EyeTV is a European brand of TV tuners that allow users to watch TV on various devices including computers and smartphones . The brand was introduced in 2002 by Elgato Systems and was sold to Geniatech in 2016.
100-569: The first EyeTV hardware device was introduced in November 2002. It was a small USB -powered device that contained a cable tuner and hardware encoder in order to convert television video into an MPEG-1 format for watching on a computer. It also had coaxial and RCA plugs to connect it with a VCR or camcorder. A 2002 article in Macworld said it was the "first step" in bridging computers and television, but at this point still had "some kinks". The next iteration
200-420: A "good" rating, saying that it was easy to install and worked well with Apple applications, but some aspects were quirky or frustrating. Sound and Vision Magazine said it was "pretty darn cool" and an easy, inexpensive way to get media server functionality, though there were some user interface quirks. It gave the product an 89 out of 100 rating. By 2005, several other EyeTV products had been introduced, such as
300-474: A 5:3 (1.67:1) aspect ratio and 60 Hz refresh rate. The Society of Motion Picture and Television Engineers (SMPTE), headed by Charles Ginsburg, became the testing and study authority for HDTV technology in the international theater. SMPTE would test HDTV systems from different companies from every conceivable perspective, but the problem of combining the different formats plagued the technology for many years. There were four major HDTV systems tested by SMPTE in
400-445: A built-in hub that connects to the physical USB cable. USB device communication is based on pipes (logical channels). A pipe connects the host controller to a logical entity within a device, called an endpoint . Because pipes correspond to endpoints, the terms are sometimes used interchangeably. Each USB device can have up to 32 endpoints (16 in and 16 out ), though it is rare to have so many. Endpoints are defined and numbered by
500-617: A clearer, more detailed picture. In addition, progressive scan and higher frame rates result in a picture with less flicker and better rendering of fast motion. Modern HDTV began broadcasting in 1989 in Japan, under the MUSE /Hi-Vision analog system. HDTV was widely adopted worldwide in the late 2000s. All modern high-definition broadcasts utilize digital television standards. The major digital television broadcast standards used for terrestrial, cable, satellite, and mobile devices are: These standards use
600-420: A comprehensive HDTV standard was not in the end established, agreement on the aspect ratio was achieved. Initially the existing 5:3 aspect ratio had been the main candidate but, due to the influence of widescreen cinema, the aspect ratio 16:9 (1.78) eventually emerged as being a reasonable compromise between 5:3 (1.67) and the common 1.85 widescreen cinema format. An aspect ratio of 16:9 was duly agreed upon at
700-525: A difficult-to-find Edit button. Some of the iHome software, which plays video content from a computer onto a television, was released in 2006 as a universal binary. Version 2.4 of the EyeTV software was released in 2007 and added an export tool for Apple TV. As of February 2015, EyeTV no longer sells ATSC tuners. (ATSC is the digital television standard used in the United States, Canada, South Korea, Mexico and
800-718: A digital format from DVB. The first regular broadcasts began on January 1, 2004, when the Belgian company Euro1080 launched the HD1 channel with the traditional Vienna New Year's Concert . Test transmissions had been active since the IBC exhibition in September 2003, but the New Year's Day broadcast marked the official launch of the HD1 channel, and the official start of direct-to-home HDTV in Europe. Euro1080,
900-404: A division of the later defunct Belgian TV services company Alfacam, broadcast HDTV channels to break the pan-European stalemate of "no HD broadcasts mean no HD TVs bought means no HD broadcasts ..." and kick-start HDTV interest in Europe. The HD1 channel was initially free-to-air and mainly comprised sporting, dramatic, musical and other cultural events broadcast with a multi-lingual soundtrack on
1000-556: A global recommendation for Analog HDTV. These recommendations, however, did not fit in the broadcasting bands which could reach home users. The standardization of MPEG-1 in 1993 led to the acceptance of recommendations ITU-R BT.709 . In anticipation of these standards, the DVB organization was formed. It was alliance of broadcasters, consumer electronics manufacturers and regulatory bodies. The DVB develops and agrees upon specifications which are formally standardised by ETSI . DVB created first
1100-400: A much wider set of frame rates: 59.94i, 60i, 23.976p, 24p, 29.97p, 30p, 59.94p and 60p. In the days of standard-definition television, the fractional rates were often rounded up to whole numbers, e.g. 23.976p was often called 24p, or 59.94i was often called 60i. Sixty Hertz high definition television supports both fractional and slightly different integer rates, therefore strict usage of notation

The USB 3.2 specification added a second lane to the Enhanced SuperSpeed System besides other enhancements so that the SuperSpeedPlus USB system part implements the Gen 1×2 , Gen 2×1, and Gen 2×2 operation modes. However, the SuperSpeed USB part of the system still implements
1300-434: A rolling schedule of four or five hours per day. These first European HDTV broadcasts used the 1080i format with MPEG-2 compression on a DVB-S signal from SES 's Astra 1H satellite. Euro1080 transmissions later changed to MPEG-4/AVC compression on a DVB-S2 signal in line with subsequent broadcast channels in Europe. Despite delays in some countries, the number of European HD channels and viewers has risen steadily since
1400-534: A standard to replace virtually all common ports on computers, mobile devices, peripherals, power supplies, and manifold other small electronics. In the current standard, the USB-C connector replaces the many various connectors for power (up to 240 W), displays (e.g. DisplayPort, HDMI), and many other uses, as well as all previous USB connectors. As of 2024, USB consists of four generations of specifications: USB 1. x , USB 2.0 , USB 3. x , and USB4 . USB4 enhances
1500-625: A tethered connection (that is: no plug or receptacle at the peripheral end). There was no known miniature type A connector until USB 2.0 (revision 1.01) introduced one. USB 2.0 was released in April 2000, adding a higher maximum signaling rate of 480 Mbit/s (maximum theoretical data throughput 53 MByte/s ) named High Speed or High Bandwidth , in addition to the USB ;1. x Full Speed signaling rate of 12 Mbit/s (maximum theoretical data throughput 1.2 MByte/s). Modifications to
1600-551: A top broadcasting administrator in Japan admitted failure of its analog-based HDTV system, saying the U.S. digital format would be more likely a worldwide standard. However this announcement drew angry protests from broadcasters and electronic companies who invested heavily into the analog system. As a result, he took back his statement the next day saying that the government will continue to promote Hi-Vision/MUSE. That year NHK started development of digital television in an attempt to catch back up to America and Europe. This resulted in
1700-507: A variety of video codecs , some of which are also used for internet video . The term high definition once described a series of television systems first announced in 1933 and launched starting in August 1936; however, these systems were only high definition when compared to earlier systems that were based on mechanical systems with as few as 30 lines of resolution. The ongoing competition between companies and nations to create true HDTV spanned
1800-500: Is full-duplex ; all earlier implementations, USB 1.0-2.0, are all half-duplex, arbitrated by the host. Low-power and high-power devices remain operational with this standard, but devices implementing SuperSpeed can provide increased current of between 150 mA and 900 mA, by discrete steps of 150 mA. USB 3.0 also introduced the USB Attached SCSI protocol (UASP) , which provides generally faster transfer speeds than

A bi-directional endpoint, on the other hand, accepts both IN and OUT packets. High-definition television High-definition television ( HDTV ) describes a television or video system which provides a substantially higher image resolution than
2000-611: Is a USB-powered device with dual tuners for receiving over the air television broadcasts. The tuners can be used simultaneously for an optimized signal, or one tuner can be used to record a channel, while another is used to watch a separate show. Diversity was first introduced in November 2006. A driver in 2009 added compatibility with Windows 7. A review in TechRadar gave EyeTV Diversity five out of five stars. PC Advisor and Pocket-Lint both gave it four out of five stars. EyeTV Hybrid, which can pick up digital or analog television broadcasts,
2100-876: Is also an EyeTV iPhone app that allows the user to watch their recorded shows on their iPhone, control their EyeTV recordings or watch live TV while connected to Wi-Fi. A compact version for laptops, the EyeTV GO, was introduced in May 2014. USB Universal Serial Bus ( USB ) is an industry standard , developed by USB Implementers Forum (USB-IF), that allows data exchange and delivery of power between many types of electronics. It specifies its architecture, in particular its physical interface , and communication protocols for data transfer and power delivery to and from hosts , such as personal computers , to and from peripheral devices , e.g. displays, keyboards, and mass storage devices, and to and from intermediate hubs , which multiply

Pictures show only receptacles: The Universal Serial Bus was developed to simplify and improve the interface between personal computers and peripheral devices, such as cell phones, computer accessories, and monitors, when compared with previously existing standard or ad hoc proprietary interfaces. From the computer user's perspective,
2300-486: Is no single standard for HDTV color support. Colors are typically broadcast using a (10-bits per channel) YUV color space but, depending on the underlying image generating technologies of the receiver, are then subsequently converted to a RGB color space using standardized algorithms. When transmitted directly through the Internet, the colors are typically pre-converted to 8-bit RGB channels for additional storage savings with
2400-491: Is not the first HDTV service over digital terrestrial television in Europe; Italy's RAI started broadcasting in 1080i on April 24, 2008, using the DVB-T transmission standard. In October 2008, France deployed five high definition channels using DVB-T transmission standard on digital terrestrial distribution. HDTV broadcast systems are identified with three major parameters: If all three parameters are used, they are specified in
2500-437: Is required to avoid ambiguity. Nevertheless, 29.97p/59.94i is almost universally called 60i, likewise 23.976p is called 24p. For the commercial naming of a product, the frame rate is often dropped and is implied from context (e.g., a 1080i television set ). A frame rate can also be specified without a resolution. For example, 24p means 24 progressive scan frames per second, and 50i means 25 interlaced frames per second. There
2600-499: Is the use of highly efficient modulation techniques for further reducing bandwidth, and foremost for reducing receiver-hardware and antenna requirements. In 1983, the International Telecommunication Union's radio telecommunications sector (ITU-R) set up a working party (IWP11/6) with the aim of setting a single international HDTV standard. One of the thornier issues concerned a suitable frame/field refresh rate,
2700-468: Is used in all digital HDTV storage and transmission systems will distort the received picture when compared to the uncompressed source. ATSC and DVB define the following frame rates for use with the various broadcast standards: The optimum format for a broadcast depends upon the type of videographic recording medium used and the image's characteristics. For best fidelity to the source, the transmitted field ratio, lines, and frame rate should match those of
2800-506: The Federal Communications Commission (FCC) because of their higher bandwidth requirements. At this time, the number of television channels was growing rapidly and bandwidth was already a problem. A new standard had to be more efficient, needing less bandwidth for HDTV than the existing NTSC. The limited standardization of analog HDTV in the 1990s did not lead to global HDTV adoption as technical and economic constraints at
2900-535: The ISDB format. Japan started digital satellite and HDTV broadcasting in December 2000. High-definition digital television was not possible with uncompressed video , which requires a bandwidth exceeding 1 Gbit/s for studio-quality HD digital video . Digital HDTV was made possible by the development of discrete cosine transform (DCT) video compression . DCT coding is a lossy image compression technique that
3000-457: The 240-line with its 25 Hz frame rate. The 240-line system could have doubled its frame rate but this would have meant that the transmitted signal would have doubled in bandwidth, an unacceptable option as the video baseband bandwidth was required to be not more than 3 MHz. Color broadcasts started at similar line counts, first with the US NTSC color system in 1953, which was compatible with
3100-485: The 5, 10, and 20 Gbit/s capabilities as SuperSpeed USB 5Gbps , SuperSpeed USB 10 Gbps , and SuperSpeed USB 20 Gbps , respectively. In 2023, they were replaced again, removing "SuperSpeed" , with USB 5Gbps , USB 10Gbps , and USB 20Gbps . With new Packaging and Port logos. The USB4 specification was released on 29 August 2019 by the USB Implementers Forum. The USB4 2.0 specification

The first one preserves USB 3.0's SuperSpeed architecture and protocol and its operation mode is newly named USB 3.1 Gen 1 , and the second version introduces a distinctively new SuperSpeedPlus architecture and protocol with a second operation mode named as USB 3.1 Gen 2 (marketed as SuperSpeed+ USB ). SuperSpeed+ doubles
3300-448: The CMTT and ETSI, along with research by Italian broadcaster RAI , developed a DCT video codec that broadcast near-studio-quality HDTV transmission at about 70–140 Mbit/s. The first HDTV transmissions in Europe, albeit not direct-to-home, began in 1990, when RAI broadcast the 1990 FIFA World Cup using several experimental HDTV technologies, including the digital DCT-based EU 256 codec,
3400-666: The Dominican Republic.) The Elgato web site explicitly declined to give a reason: "Elgato Technical Support is not able to comment on this business decision." In February 2016, Elgato sold EyeTV to Geniatech Europe GmbH, a wholly owned subsidiary of Shenzhen Geniatech Inc., Ltd. Geniatech will take over the complete EyeTV product line. This company no longer sells the Turbo.264 HD software and reduced digital TV tuners to one model. The Thunderbolt products remained with Elgato until they were sold to Corsair Gaming in 2018.

3500-504: The Eye TV EZ. The EZ was a basic, entry-level product with an analog tuner for watching TV on a Mac computer. In 2006, version 2.1 of the EyeTV software was introduced with a new user-interface, an integrated TV guide from TitanTV and compatibility with Apple remotes. The interface was similar to that of other Apple products. An article in Macworld praised the update and especially the new editing features, but said it had some quirks, such as
3600-549: The EyeTV HD product for recording high-definition cable and satellite programming was introduced. Because cable and satellite signals are encoded, the device must be connected to a tuner from a television provider. Then it provides remote controls, recording and DVR-functionality from a connected computer. A Macworld review gave the product four out of five stars. A review in Laptop Magazine gave EyeTV HD 3.5 out of 5 stars. It said

The EyeTV for DTT (digital terrestrial TV) is a small USB-powered device with an antenna for receiving free over-the-air television broadcasts. It received a 4 out of 5 rating in TechRadar. A review in The Register gave it an 85 percent rating. The Eye TV Wonder was only available from July 2005 to January 2006, before being discontinued and replaced with
3800-517: The Japanese public broadcaster NHK first developed consumer high-definition television with a 5:3 display aspect ratio. The system, known as Hi-Vision or MUSE after its multiple sub-Nyquist sampling encoding (MUSE) for encoding the signal, required about twice the bandwidth of the existing NTSC system but provided about four times the resolution (1035i/1125 lines). In 1981, the MUSE system was demonstrated for

4600-465: The United States saw Hi-Vision/MUSE as an outdated system and had already made it clear that it would develop an all-digital system. Experts thought the commercial Hi-Vision system in 1992 was already eclipsed by digital technology developed in the U.S. since 1990. This was an American victory against the Japanese in terms of technological dominance. By mid-1993 prices of receivers were still as high as 1.5 million yen (US$ 15,000). On February 23, 1994,

European standards did not follow until the 1960s, when the PAL and SECAM color systems were added to the monochrome 625-line broadcasts. The NHK (Japan Broadcasting Corporation) began researching to "unlock the fundamental mechanism of video and sound interactions with the five human senses" in 1964, after the Tokyo Olympics. NHK set out to create an HDTV system that scored much higher in subjective tests than NTSC's previously dubbed HDTV . This new system, NHK Color, created in 1972, included 1125 lines,

USB devices are linked in series through hubs. The hub built into
6000-1084: The following form: [frame size][scanning system][frame or field rate] or [frame size]/[frame or field rate][scanning system] . Often, frame size or frame rate can be dropped if its value is implied from context. In this case, the remaining numeric parameter is specified first, followed by the scanning system. For example, 1920×1080p25 identifies progressive scanning format with 25 frames per second, each frame being 1,920 pixels wide and 1,080 pixels high. The 1080i25 or 1080i50 notation identifies interlaced scanning format with 25 frames (50 fields) per second, each frame being 1,920 pixels wide and 1,080 pixels high. The 1080i30 or 1080i60 notation identifies interlaced scanning format with 30 frames (60 fields) per second, each frame being 1,920 pixels wide and 1,080 pixels high. The 720p60 notation identifies progressive scanning format with 60 frames per second, each frame being 720 pixels high; 1,280 pixels horizontally are implied. Systems using 50 Hz support three scanning rates: 50i, 25p and 50p, while 60 Hz systems support

Early HDTV broadcasting used analog technology that
6500-964: The latest versions of the standard extend the power delivery limits for battery charging and devices requiring up to 240 watts ( USB Power Delivery (USB-PD) ). Over the years, USB(-PD) has been adopted as the standard power supply and charging format for many mobile devices, such as mobile phones, reducing the need for proprietary chargers. USB was designed to standardize the connection of peripherals to personal computers, both to exchange data and to supply electric power. It has largely replaced interfaces such as serial ports and parallel ports and has become commonplace on various devices. Peripherals connected via USB include computer keyboards and mice, video cameras, printers, portable media players, mobile (portable) digital telephones, disk drives, and network adapters. USB connectors have been increasingly replacing other types of charging cables for portable devices. USB connector interfaces are classified into three types:

Between 1988 and 1991, several European organizations were working on discrete cosine transform (DCT) based digital video coding standards for both SDTV and HDTV. The EU 256 project by
6800-609: The many various legacy Type-A (upstream) and Type-B (downstream) connectors found on hosts , hubs , and peripheral devices , and the modern Type-C ( USB-C ) connector, which replaces the many legacy connectors as the only applicable connector for USB4. The Type-A and Type-B connectors came in Standard, Mini, and Micro sizes. The standard format was the largest and was mainly used for desktop and larger peripheral equipment. The Mini-USB connectors (Mini-A, Mini-B, Mini-AB) were introduced for mobile devices. Still, they were quickly replaced by
6900-539: The maximum signaling rate to 10 Gbit/s (later marketed as SuperSpeed USB 10 Gbps by the USB 3.2 specification), while reducing line encoding overhead to just 3% by changing the encoding scheme to 128b/132b . USB 3.2 , released in September 2017, preserves existing USB 3.1 SuperSpeed and SuperSpeedPlus architectures and protocols and their respective operation modes, but introduces two additional SuperSpeedPlus operation modes ( USB 3.2 Gen 1×2 and USB 3.2 Gen 2×2 ) with
7000-579: The mixed analog-digital HD-MAC technology, and the analog MUSE technology. The matches were shown in 8 cinemas in Italy, where the tournament was played, and 2 in Spain. The connection with Spain was made via the Olympus satellite link from Rome to Barcelona and then with a fiber optic connection from Barcelona to Madrid . After some HDTV transmissions in Europe, the standard was abandoned in 1993, to be replaced by
7100-504: The new USB-C Fabric with signaling rates of 10 and 20 Gbit/s (raw data rates of 1212 and 2424 MB/s). The increase in bandwidth is a result of two-lane operation over existing wires that were originally intended for flip-flop capabilities of the USB-C connector. Starting with the USB 3.2 specification, USB-IF introduced a new naming scheme. To help companies with the branding of the different operation modes, USB-IF recommended branding
7200-452: The number of a host's ports. Introduced in 1996, USB was originally designed to standardize the connection of peripherals to computers, replacing various interfaces such as serial ports , parallel ports , game ports , and ADB ports. Early versions of USB became commonplace on a wide range of devices, such as keyboards, mice, cameras, printers, scanners, flash drives, smartphones, game consoles, and power banks. USB has since evolved into
7300-537: The one-lane Gen 1×1 operation mode. Therefore, two-lane operations, namely USB 3.2 Gen 1× 2 (10 Gbit/s) and Gen 2× 2 (20 Gbit/s), are only possible with Full-Featured USB-C. As of 2023, they are somewhat rarely implemented; Intel, however, started to include them in its 11th-generation SoC processor models, but Apple never provided them. On the other hand, USB 3.2 Gen 1(×1) (5 Gbit/s) and Gen 2(×1) (10 Gbit/s) have been quite common for some years. Each USB connection
7400-472: The optional functionality as Thunderbolt 4 products. USB4 2.0 with 80 Gbit/s speeds was to be revealed in November 2022. Further technical details were to be released at two USB developer days scheduled for November 2022. The USB4 specification states that the following technologies shall be supported by USB4: Because of the previous confusing naming schemes, USB-IF decided to change it once again. As of 2 September 2022, marketing names follow
7500-518: The peripheral device. Developers of USB devices intended for public sale generally must obtain a USB ID, which requires that they pay a fee to the USB Implementers Forum (USB-IF). Developers of products that use the USB specification must sign an agreement with the USB-IF. Use of the USB logos on the product requires annual fees and membership in the organization. A group of seven companies began
7600-541: The previous generation of technologies. The term has been used since at least 1933; in more recent times, it refers to the generation following standard-definition television (SDTV). It is the standard video format used in most broadcasts: terrestrial broadcast television , cable television , satellite television . HDTV may be transmitted in various formats: When transmitted at two megapixels per frame, HDTV provides about five times as many pixels as SD (standard-definition television). The increased resolution provides for
7700-491: The same encoding. It also includes the alternative 1440×1152 HDMAC scan format. (According to some reports, a mooted 750-line (720p) format (720 progressively scanned lines) was viewed by some at the ITU as an enhanced television format rather than a true HDTV format, and so was not included, although 1920×1080i and 1280×720p systems for a range of frame and field rates were defined by several US SMPTE standards.) HDTV technology
7800-484: The standard at Intel; the first integrated circuits supporting USB were produced by Intel in 1995. Released in January 1996, USB 1.0 specified signaling rates of 1.5 Mbit/s ( Low Bandwidth or Low Speed ) and 12 Mbit/s ( Full Speed ). It did not allow for extension cables, due to timing and power limitations. Few USB devices made it to the market until USB 1.1 was released in August 1998. USB 1.1
7900-573: The standard for DVB-S digital satellite TV, DVB-C digital cable TV and DVB-T digital terrestrial TV. These broadcasting systems can be used for both SDTV and HDTV. In the US the Grand Alliance proposed ATSC as the new standard for SDTV and HDTV. Both ATSC and DVB were based on the MPEG-2 standard, although DVB systems may also be used to transmit video using the newer and more efficient H.264/MPEG-4 AVC compression standards. Common for all DVB standards
8000-477: The syntax "USB x Gbps", where x is the speed of transfer in Gbit/s. Overview of the updated names and logos can be seen in the adjacent table. The operation modes USB 3.2 Gen 2×2 and USB4 Gen 2×2 – or: USB 3.2 Gen 2×1 and USB4 Gen 2×1 – are not interchangeable or compatible; all participating controllers must operate with the same mode. This version incorporates
8100-415: The thinner Micro-USB connectors (Micro-A, Micro-B, Micro-AB). The Type-C connector, also known as USB-C, is not exclusive to USB, is the only current standard for USB, is required for USB4, and is required by other standards, including modern DisplayPort and Thunderbolt. It is reversible and can support various functionalities and protocols, including USB; some are mandatory, and many are optional, depending on
8200-489: The three existing operation modes. Its efficiency is dependent on a number of factors including physical symbol encoding and link-level overhead. At a 5 Gbit/s signaling rate with 8b/10b encoding , each byte needs 10 bits to transmit, so the raw throughput is 500 MB/s. When flow control, packet framing and protocol overhead are considered, it is realistic for about two thirds of the raw throughput, or 330 MB/s to transmit to an application. SuperSpeed's architecture
8300-539: The time did not permit HDTV to use bandwidths greater than normal television. Early HDTV commercial experiments, such as NHK's MUSE, required over four times the bandwidth of a standard-definition broadcast. Despite efforts made to reduce analog HDTV to about twice the bandwidth of SDTV, these television formats were still distributable only by satellite. In Europe too, the HD-MAC standard was considered not technically viable. In addition, recording and reproducing an HDTV signal
8400-468: The type of hardware: host, peripheral device, or hub. USB specifications provide backward compatibility, usually resulting in decreased signaling rates, maximal power offered, and other capabilities. The USB 1.1 specification replaces USB 1.0. The USB 2.0 specification is backward-compatible with USB 1.0/1.1. The USB 3.2 specification replaces USB 3.1 (and USB 3.0) while including the USB 2.0 specification. USB4 "functionally replaces" USB 3.2 while retaining
8500-424: The world already having split into two camps, 25/50 Hz and 30/60 Hz, largely due to the differences in mains frequency. The IWP11/6 working party considered many views and throughout the 1980s served to encourage development in a number of video digital processing areas, not least conversion between the two main frame/field rates using motion vectors , which led to further developments in other areas. While
8600-532: Was a research project and the system was never deployed by either the military or consumer broadcasting. In 1986, the European Community proposed HD-MAC , an analog HDTV system with 1,152 lines. A public demonstration took place for the 1992 Summer Olympics in Barcelona. However HD-MAC was scrapped in 1993 and the DVB project was formed, which would foresee development of a digital HDTV standard. In 1979,
8700-677: Was a significant technical challenge in the early years of HDTV ( Sony HDVS ). Japan remained the only country with successful public broadcasting of analog HDTV, with seven broadcasters sharing a single channel. However, the Hi-Vision/MUSE system also faced commercial issues when it launched on November 25, 1991. Only 2,000 HDTV sets were sold by that day, rather than the enthusiastic 1.32 million estimation. Hi-Vision sets were very expensive, up to US$ 30,000 each, which contributed to its low consumer adaption. A Hi-Vision VCR from NEC released at Christmas time retailed for US$ 115,000. In addition,
8800-607: Was announced at the 2011 International Franchise Conference as the first tuner for the new Freeview system in the United Kingdom. Subsequently the EyeTV Mobile and EyeTV Micro products were released for iPhones and Android respectively. The Micro and Mobile allow users to watch or record free over-the-air television programming from their smartphone. Reviews of the mobile products ranged from 2 out of 5 stars by CNET 4 out of 5 stars in Macworld and 3 out of 5 stars in PC Magazine . There
8900-489: Was discontinued in February 1937. In 1938 France followed with its own 441-line system, variants of which were also used by a number of other countries. The US NTSC 525-line system joined in 1941. In 1949 France introduced an even higher-resolution standard at 819 lines , a system that would have been high definition even by modern standards, but was monochrome only and had technical limitations that prevented it from achieving
9000-578: Was first proposed by Nasir Ahmed in 1972, and was later adapted into a motion-compensated DCT algorithm for video coding standards such as the H.26x formats from 1988 onwards and the MPEG formats from 1993 onwards. Motion-compensated DCT compression significantly reduces the amount of bandwidth required for a digital TV signal. By 1991, it had achieved data compression ratios from 8:1 to 14:1 for near-studio-quality HDTV transmission, down to 70–140 Mbit/s . Between 1988 and 1991, DCT video compression
9100-405: Was first released in early 2009. A CNET review said the device was easy and effective to use, but that buffering was often too slow to make watching live TV practical. Macworld said EyeTV's "core strength" was recording scheduled TV shows. A review in PC Magazine gave the product 3.5 out of 5 stars. The review said it "works exceptionally well" but doesn't come with Windows software. In June 2010,
9200-517: Was introduced in Europe in late 2009. The Register gave it an 80% rating, saying that it "works well" and that the documentation did not make it clear how to install the Apple and Windows versions of the software. The EyeTV software was updated to version 3.0 in 2008. 3.0 made user interface improvements, such as being able to mark favorites or automatically record shows in a series. A review in TechRadar gave it 4.5 out of 5 stars. The review noted that EyeTV
9300-437: Was introduced in November 2013. It is a small 44 gram device that receives free digital over-the-air television broadcasts and makes it available to portable devices through a wireless hot spot. A review in Macworld said it was portable, easy to use and had good battery life, but noted that users can't connect to other WiFi networks and watch TV at the same time. It gave the product 4 out of 5 stars. An EyeTV Mobile device for iPads
9400-594: Was introduced in the United States in the early 1990s and made official in 1993 by the Digital HDTV Grand Alliance , a group of television, electronic equipment, communications companies consisting of AT&T Bell Labs , General Instrument , Philips , Sarnoff , Thomson , Zenith and the Massachusetts Institute of Technology . Field testing of HDTV at 199 sites in the United States was completed August 14, 1994. The first public HDTV broadcast in
9500-630: Was later converted to digital television with video compression . In 1949, France started its transmissions with an 819 lines system (with 737 active lines). The system was monochrome only and was used only on VHF for the first French TV channel. It was discontinued in 1983. In 1958, the Soviet Union developed Тransformator ( Russian : Трансформатор , meaning Transformer ), the first high-resolution (definition) television system capable of producing an image composed of 1,125 lines of resolution aimed at providing teleconferencing for military command. It
9600-483: Was released in 2004 and called EyeTV 200. EyeTV 200 introduced a digital remote control and converted video programming into the higher-quality MPEG-2 format. A Macworld review gave it 4 out of 5 stars for "very good" and emphasized the video quality and ease-of-use. A story in The Washington Post said it was more expensive than some alternatives, but worked on a Mac and had good-quality recordings. Also in 2004
9700-524: Was released on 1 September 2022 by the USB Implementers Forum. USB4 is based on the Thunderbolt 3 protocol. It supports 40 Gbit/s throughput, is compatible with Thunderbolt 3, and backward compatible with USB 3.2 and USB 2.0. The architecture defines a method to share a single high-speed link with multiple end device types dynamically that best serves the transfer of data by type and application. During CES 2020 , USB-IF and Intel stated their intention to allow USB4 products that support all
9800-540: Was the de facto software for TV and computer video integration and praised its new features, but said it was expensive when purchased separately. A 2007 article in MacLife said their "top picks" for USB-powered tuners were those using the EyeTV software, such as the EyeTV hybrid or EyeTV 250. In addition to Elgato's EyeTV line of consumer devices, other brands such as Terratec and Miglia used the EyeTV software in their products through licensing agreements with Elgato. The EyeTV W
9900-434: Was the earliest revision that was widely adopted and led to what Microsoft designated the " Legacy-free PC ". Neither USB 1.0 nor 1.1 specified a design for any connector smaller than the standard type A or type B. Though many designs for a miniaturized type B connector appeared on many peripherals, conformity to the USB 1. x standard was hampered by treating peripherals that had miniature connectors as though they had
10000-530: Was widely adopted as the video coding standard for HDTV implementations, enabling the development of practical digital HDTV. Dynamic random-access memory ( DRAM ) was also adopted as framebuffer semiconductor memory, with the DRAM semiconductor industry 's increased manufacturing and reducing prices important to the commercialization of HDTV. Since 1972, International Telecommunication Union 's radio telecommunications sector ( ITU-R ) had been working on creating
