This article has multiple issues. Wikipedia’s norms and to be inclusive creo 2.0 mechanism tutorial pdf all essential details. The increased resolution provides for a clearer, more detailed picture.

In addition, progressive scan and higher frame rates resulting in a picture with less flicker and better rendering of fast motion. The ongoing competition between companies and nations to create true “HDTV” spanned the entire 20th century, as each new system became more HD than the last. In the beginning of the 21st century, this race has continued with 4k, 5k and current 8K systems. The Baird system was discontinued in February 1937.

525-line system joined in 1941. 405-line system which started as 5:4 and later changed to 4:3. 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 similarly higher resolutions, first with the US NTSC color system in 1953, which was compatible with the earlier monochrome systems and therefore had the same 525 lines of resolution. 1964, after the Tokyo Olympics.

NHK set out to create an HDTV system that ended up scoring much higher in subjective tests than NTSC’s previously dubbed “HDTV”. This new system, NHK Color, created in 1972, included 1125 lines, a 5:3 aspect ratio and 60 Hz refresh rate. 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. The system was monochrome only, and was used only on VHF for the first French TV channel.

It was discontinued in 1983. 1,125 lines of resolution aimed at providing teleconferencing for military command. It was a research project and the system was never deployed by either the military or consumer broadcasting. 9ch commencing on November 25, 1994, which featured commercial and NHK programming. In 1981, the MUSE system was demonstrated for the first time in the United States, using the same 5:3 aspect ratio as the Japanese system. Several systems were proposed as the new standard for the US, including the Japanese MUSE system, but all were rejected by the FCC because of their higher bandwidth requirements.
