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
440-617: 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
528-420: 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
616-718: 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,

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
792-411: A format typical of the late 1940s, with a combination of information, music, and sports. When CHUM was about to debut, Leary told the press that the new station would be known for community service and in-depth news, in addition to live talent and the most popular phonograph records. Allan Waters , a salesman from Part's patent medicine business took control of CHUM-AM in 1954. Waters' first major move
880-556: 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
968-400: 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

Between 2008 and 2009, Corus Entertainment acquired SexTV: The Channel, CLT, and Drive-In Classics from CTV Ltd. for an estimated worth of $ 73 million and $ 40 million each. However, it was announced that CTVglobemedia would be selling CKX-TV in Brandon, Manitoba to Bluepoint Investment Corporation for a dollar. But that station was closed down on October 2, 2009, after Bluepoint rejected
1144-1043: A package of games for the Toronto Raptors , Toronto's then-new NBA franchise. The resulting station became known as The New VR . That same year, the CHUM Radio Network was established to deliver syndicated radio programs across Canada. The experiment was successful enough that CHUM replicated CKVR's format on several stations it had acquired from Baton Broadcasting in 1997, including CHRO in Pembroke , CFPL in London , CKNX in Wingham , and CHWI in Windsor . Most of these stations were also former CBC affiliates, and all were in markets where CKVR's sister station, CITY-TV, were already available on basic cable. CIVI in Victoria, British Columbia
1232-525: A pivotal role in the company's development. The company expanded into television holdings for the first time when it gained a one-third interest in CBC affiliate CKVR-TV , a station founded by Ralph Snelgrove (whose first initial and that of his wife, Valerie, form part of the station's callsign), in Barrie. It acquired a second one-third share in 1968, and eventually gained full control in 1970. On May 12, 1967, under

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
1408-495: A service "designed for an adult audience that will be devoted to music in all its forms ". On September 4, 1996, the CRTC approved CHUM and Radiomutel's application for Musimax. The channel launched on September 8, 1997. In June 1999, Astral Media announced it would take over Radiomutuel and gain control of Radiomutuel's assets including MusiMax shortly thereafter. In July 2006, CTVglobemedia announced it would acquire CHUM Limited. While

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

Remstar also successfully applied to have the amount of music-oriented programming the channel must air reduced to 80%. The sale was closed on September 16, 2014. On August 29, 2016, MusiMax rebranded as Max , switching to a general entertainment format. On August 23, 2010, Astral launched
1760-551: 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
1848-507: 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

In 2016, Remstar relaunched MusiMax as Max into its current format while M3 (the former MuchMoreMusic) was replaced into the Canadian version of Gusto, which was renamed into CTV Life Channel in 2019. As a former Category A service , Max was required to be carried on the basic service of all digital television providers serving the province of Quebec. The channel was, and still is, typically offered optionally at
2024-486: 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
2112-491: 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
2200-437: 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
2288-499: 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,

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
2464-667: The Citytv brand. At the same time, CHUM announced plans to consolidate the master control departments for CKVR, CFPL, CHRO, CHWI and CKNX at 299 Queen Street West in Toronto, as well as the traffic and programming departments at CFPL, resulting in the loss of approximately nine staff members from CKVR. The switch occurred on June 3, 2005. Allan Waters stepped down from the CHUM Limited Board of Directors in October and became an honorary director. On December 3, 2005, Waters died in Toronto at

CTVgm's takeover bid was completed on October 30, although CHUM was immediately in a blind trust under lawyer John McKellar. Immediately following the announcement, CHUM separately announced 281 layoffs, primarily at its local stations in western Canada; local newscasts (other than Breakfast Television and
2640-506: 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
2728-535: 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

Rogers subsequently purchased 33 Dundas Street East, the former Olympic Spirit building, located at the edge of Dundas Square for the use of its Toronto television stations, and CITY-TV moved out from 299 Queen Street West into the new facility on September 8, 2009. In 2010, CP24 extended their 5:00pm newscast after
3256-517: 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

CHUM claims the layoffs were part of an ongoing process to streamline its operations and not directly related to the takeover. On June 8, 2007, the CRTC approved the CTV takeover of CHUM. However, the CRTC made the deal conditional on CTV divesting itself of Citytv rather than A-Channel. This consequently voided

CTV said it would keep all other assets, except CHUM's interest in MusiquePlus/MusiMax, and potentially CKX-TV and CLT . The sale of the CHUM Limited properties to CTVglobemedia was completed on June 22, 2007 with CTVgm as the sole owner of CHUM. The Citytv stations remained under blind trust awaiting sale to Rogers Media (see below). Following

3696-465: 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,

CHUM Limited first pursued a license from the CRTC for MuchMoreMusic —an adult contemporary counterpart to MuchMusic —in 1993, as part of a round of applications for new specialty channels. CHUM also proposed MusiquExtra, a French-language counterpart that would be a sister to MusiquePlus . The CRTC approved only Maclean-Hunter and Rawlco Communications ' The Country Network , denying all other applicants. CHUM submitted its proposals again in January 1996; they included both MuchMoreMusic and its French counterpart with Radiomutuel, now known as MusiMax, which proposed

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.

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
5808-579: 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
5896-673: The sale of Moses Znaimer's interest in the station. In 1987, CITY and the other CHUM-owned television stations moved to the CHUM-City Building at 299 Queen Street West , which became one of the most recognizable landmarks in the city. The CHUM Radio Building at 1331 Yonge Street remained CHUM Limited's corporate headquarters. Between 1984 and 1999, CHUM Limited expanded into many new television holdings such as MuchMusic , Star! , Space , Bravo !, CP24 , SexTV: The Channel , Fashion Television Channel , Canadian Learning Television , and many others. In September 1995, CKVR disaffiliated from
5984-533: The sale to CTVgm. As Shaw Communications purchasing the Global Television Network and the Canwest television properties, Vidéotron launching its wireless telephone network with video content as a key selling point, and the enormous popularity of wireless and Internet video and other media streams at the 2010 Vancouver Olympics , Bell once again sought to bring a content provider into its portfolio. It
6072-491: 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
6160-573: 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
6248-472: The station manager at CKCL for 14 years. CHUM received its licence in late November 1944 to operate a station with 1000 watts. CHUM launched as a dawn-to-dusk radio station under York Broadcasters Limited on 28 October 1945, with John H.Q. "Jack" Part, an entrepreneur in the business of patent medicines, as its president. The station, then operating from studios in the Mutual Street Arena , broadcast
6336-516: The takeover less than a month, Richard Gray was named head of news for the A-Channel stations and CKX-TV (another station in the CHUM acquisition). Gray reports directly to the CTVgm corporate group instead of CTV News to preserve independent news presentation and management. Gray now oversees CKVR and the other news departments; CHRO, CFPL, CKNX, CHWI, CIVI and CKX-TV. With CHUM Limited dissolved, there were
6424-513: The takeover. On December 4, 2013, Remstar , owners of the French television system V , announced that it would acquire MusiquePlus and MusiMax for an undisclosed amount through its subsidiary V Media Group . On September 11, 2014, the CRTC approved the sale. The acquisition is valued at $ 15.5 million; to fund the purchase, Remstar will sell 15% stakes in V Media to the Caisse , Fonds de solidarité FTQ and
6512-539: 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
6600-424: 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
6688-532: 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,
6776-677: 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,
6864-399: Was acquired by CTVglobemedia's predecessor Bell Media in 2013, MusiquePlus was sold to V Media Group, parent company of Quebec's V network . As with its English counterpart, MusiMax was formerly oriented primarily towards music programming. Due to shrinking interest in music television because of the growth of online platforms, MusiMax increasingly focused on non-music programming targeting
6952-751: Was acquired by salesman Allan Waters in 1954. CHUM had expanded to and owned 33 radio stations across Canada under its CHUM Radio Network division (now Bell Media Radio ) and also owned other radio stations. The company also operated full or joint control of 15 local television stations under the ATV , Citytv (acquired in 1981) and A-Channel (formerly NewNet, now CTV 2 ) brands, one CBC Television affiliate, one provincial educational channel, Atlantic Satellite Network in Atlantic Canada , and 20 branded specialty television channels , most notably MuchMusic and its various spin-offs that were launched under Moses Znaimer ,
7040-456: Was added into the system by CHUM at its launch in October 2001. A month prior, CHUM bought CKVU from CanWest Global and it became Citytv Vancouver on July 22, 2002. Prior to CHUM's acquisition of CKVU, some Citytv programming was syndicated to KVOS in nearby Bellingham, Washington . Moses Znaimer retired from active management at CHUM in April 2003, and briefly continued to work on projects with
7128-505: Was announced to re-acquire 100% of the company's broadcasting arm in September 2010, including CTV Limited. Under the deal, Woodbridge, Torstar, and Teachers' received $ 1.3 billion in either cash or equity in BCE, while BCE will also assume $ 1.7 billion in debt (BCE's existing equity interest is $ 200 million, for a total transaction value of $ 3.2 billion). Woodbridge will simultaneously regain majority control of The Globe and Mail , with Bell retaining
7216-489: 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
7304-578: 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
7392-594: 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
7480-630: 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
7568-629: Was one of several sources (alongside Canwest 's CH / E! and Global TV ) providing syndicated programming to independently owned CBC and CTV affiliates. CHUM announced in February 2005 that the NewNet stations would be relaunched under the A-Channel brand by that fall; the rebrand took place on August 2, 2005, the same date when the former A-Channel stations in Winnipeg , Edmonton and Calgary , recently acquired by CHUM from Craig Media, were relaunched under
7656-583: Was to secure a licence for 24-hour-a-day broadcasting for CHUM, along with a power increase to 5,000 watts. On April 17, 1959, the name York Broadcasters was changed to CHUM 1050 Radio Ltd. . The CHUM studios were moved from 250 Adelaide Street West to 1331 Yonge Street, Toronto, where their iconic neon sign was erected for the first time. CHUM-FM would begin broadcasting in 1963 under a Classical Music/Fine Arts format. Alex Forbes, whose accounting firm Ewin & Forbes had been CHUM's auditor since 1952, joined CHUM 1050 Radio Ltd. as Secretary-Treasurer. He would play
7744-530: 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
