80-508: Each episode normally airs two hours in length (condensed down from the normal two-and-a-half-hour length of a live telecast), although there have been some episodes that were only thirty to sixty minutes long, due to lack of complete footage, or were preserved as newsreels for a majority of games played in the 1950s. And there are still some episodes which were aired in a full two-and-a-half hours of game time. Some recent games, however (e.g. 2008 NBA Finals ) were shortened to only an hour despite

160-404: A cinema , newsreels were a source of current affairs, information, and entertainment for millions of moviegoers. Newsreels were typically exhibited preceding a feature film , but there were also dedicated newsreel theaters in many major cities in the 1930s and ’40s, and some large city cinemas also included a smaller theaterette where newsreels were screened continuously throughout the day. By

240-474: 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

320-625: 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

400-420: 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

480-743: 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,

560-404: 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

640-515: A few programs on NBA TV to do so. This applies only, however, to games shown before the availability of high definition (e.g. games prior to 2007). In recent years, Hardwood Classics is shown in full high definition, with black pillarboxes filling in for games originally aired in the 4:3 standard definition ratio. The episodes that have been broadcast on this series have been mostly playoffs and Finals games, but it also features significant games with great personal accomplishments, such as: As sort of

720-559: 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

800-400: 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

880-536: A newsreel story can be found in the film Citizen Kane (1941), which was prepared by RKO's actual newsreel staff. Citizen Kane includes a fictional newsreel called "News on the March" that summarizes the life of title character Charles Foster Kane while parodying The March of Time . On August 12, 1949, one hundred twenty cinema technicians employed by Associated British Pathé in London went on strike to protest

Hardwood Classics also lends its name to the Mitchell & Ness clothing line of authentic vintage NBA jerseys, as well as the annual throwback game series "Hardwood Classics Nights", featuring NBA teams in throwback uniforms . During the 2011 NBA lockout , Hardwood Classics

1040-434: 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

1120-486: A special treat for fans, NBA TV normally broadcasts a Hardwood Classics / Greatest Games episode that features a significant game between two franchises that happen to play each other in a game taking place on that same night. On or around Christmas , NBA TV shows marathons of classic Christmas Day games. These games are from as far back as 1970 and often feature the New York Knicks (with 45 appearances, by far

1200-588: A substantially higher image resolution than 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

1280-551: 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

1360-511: 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

The earliest Christmas Day telecast in the NBA TV archives is a 1970 ABC telecast, between the Hawks and Suns from the Arizona Veterans Memorial Coliseum in Phoenix , with the Suns winning 127–115. There have been several Hardwood Classics episodes that were re-edited and remastered. For instance, Game 6 of

1520-491: 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

1600-495: 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

1680-437: 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

1760-514: 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

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

The program was re-titled NBA TV: Hardwood Classics, presented by The History Channel , in March 2004 (retitled simply as NBA TV: Hardwood Classics when it moved to NBA TV in 2005). However, some episodes still run under

2480-465: The "Greatest Games" title were re-aired under the "Hardwood Classics" banner. Every Monday, Hardwood Classics was promoted as 'Old School Monday' and two games or more featuring a significant milestone or moment were aired. 'Old School Monday' airs only during the NBA off-season. Beginning in October, a variation of Hardwood Classics called 'Classic Quarters' is also aired, in which a thirty-minute episode

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

2800-452: 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,

2960-526: 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

The American Advanced Television Systems Committee (ATSC) HDTV system had its public launch on October 29, 1998, during

3440-465: 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,

3520-521: The assumption that it will only be viewed only on a ( sRGB ) computer screen. As an added benefit to the original broadcasters, the losses of the pre-conversion essentially make these files unsuitable for professional TV re-broadcasting. Most HDTV systems support resolutions and frame rates defined either in the ATSC table 3, or in EBU specification. The most common are noted below. At a minimum, HDTV has twice

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,

Upon visiting a demonstration of MUSE in Washington, US President Ronald Reagan was impressed and officially declared it "a matter of national interest" to introduce HDTV to the US. NHK taped the 1984 Summer Olympics with a Hi-Vision camera, weighing 40 kg. Satellite test broadcasts started June 4, 1989,

4320-1084: 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

In 2009, Hardwood Classics also began to broadcast condensed 30-minute episodes of the NBA All-Star Weekend Slam Dunk Contest , beginning with the 1984 contest. These programs are shown only during the month of February, which coincides with the NBA All-Star Weekend . Beginning in 2010, Hardwood Classics is hosted by Marc Fein , and later by either Matt Winer or Rick Kamla , who gives

4640-411: The intended definition. All of these systems used interlacing and a 4:3 aspect ratio except the 240-line system which was progressive (actually described at the time by the technically correct term sequential ) and the 405-line system which started as 5:4 and later changed to 4:3. The 405-line system adopted the (at that time) revolutionary idea of interlaced scanning to overcome the flicker problem of

4720-512: The late 1970s, and in 1979 an SMPTE study group released A Study of High Definition Television Systems : Since the formal adoption of Digital Video Broadcasting's (DVB) widescreen HDTV transmission modes in the mid to late 2000s; the 525-line NTSC (and PAL-M ) systems, as well as the European 625-line PAL and SECAM systems, have been regarded as standard definition television systems. Early HDTV broadcasting used analog technology that

One example of this was the Christmas Day 1985 matchup between the Knicks and the eventual champion Boston Celtics where the Knicks trailed 58–33 in the third period, yet came back to force overtime, eventually winning 114–103 in two overtimes. Another notable Knicks Christmas Day game took place

5120-458: The narrator used humorous remarks for light-hearted or non-tragic stories. In the U.S., newsreel series included The March of Time (1935–1951), Pathé News (1910–1956), Paramount News (1927–1957), Fox Movietone News (1928–1963), Hearst Metrotone News (1914–1967), and Universal Newsreel (1929–1967). Pathé News was distributed by RKO Radio Pictures from 1931 to 1947, and then by Warner Brothers from 1947 to 1956. An example of

5200-494: 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

5280-584: 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

5360-543: 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

Newsreel-producing companies excluded television companies from their distribution, but the television companies countered by sending their own camera crews to film news events. Newsreels died out because of the nightly television news broadcast, and technological advances such as electronic news-gathering for television news , introduced in

5600-545: 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,

5680-684: 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,

5760-558: Was aired on NBA TV on a daily basis, usually twice a day, primarily to fill in programming hours. This is because recent footage of active NBA players could not be aired per agreement by the league during the lockout, instead NBA TV focused on programming featuring NBA legends during this period, other than ongoing WNBA and NBA Development League games. More recent episodes focused more on an individual player or team accomplishments aside from games which feature signature plays and series/championship victories. Some games previously aired under

5840-553: Was dedicated to a particular quarter of a classic NBA game. During the 2020 NBA season break due to the COVID-19 pandemic , NBA TV aired select classic games under the Hardwood Classics Popcast title. The format brought back in-game tidbits last seen under the Greatest Games name. Even though NBA TV now airs in high definition , Hardwood Classics continue to be shown in standard definition , one of only

5920-494: 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

6000-582: 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

6080-615: 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

6160-636: 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

6240-611: Was launched in the United Kingdom, it was airing the British Movietone and Gaumont British newsreels for several years (except for a hiatus during World War II), until 1948, when the service launched their own newsreel programme, titled Television Newsreel , that would last until July 1954, when it was replaced by News and Newsreel . On February 16, 1948, NBC launched a ten-minute television program called Camel Newsreel Theatre with John Cameron Swayze that featured newsreels with Swayze doing voiceovers. Also in 1948,

6320-422: Was originally aired as a two-hour episode in 1999, but was shortened to an hour when it was re-aired in 2004, only covering the latter stages of the fourth quarter and two overtimes. Some Hardwood Classics games were aired with one portion of the broadcast handled by a local network, and another portion handled by either a national (or another local, preferably the opposing team's) network, handling play-by-play for

6400-534: 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
