A 14-inch reel of 2-inch quad videotape compared with a modern-day MiniDV videocassette. Both media store one hour of color video. The first commercial professional broadcast quality videotape machines capable of replacing kinescopes were the two-inch quadruplex videotape (Quad) machines introduced by Ampex on April 14, 1956, at the National Association of Broadcasters convention in Chicago.
Coupled with the slow horizontal tape speed, the sound was comparable with that of a low-quality audio cassette. By contrast, all Video8 machines used audio frequency modulation (AFM) to record sound along the same helical tape path as that of the video signal. This meant that Video8's standard audio was of a far higher quality than that of its ...
Ampex created the first D-2 video machine, the ACR-225 commercial spot player [2] working with Sony, who had done some early research into composite digital video, [3] as a cost-effective solution for TV broadcasters with large investments in composite analog infrastructure such as video routers and switchers, since it could be inserted into existing analog broadcast facilities without ...

Below is a list of broadcast video formats. 24p is a progressive scan format and is now widely adopted by those planning on transferring a video signal to film. Film and video makers use 24p even if they are not going to transfer their productions to film, simply because of the on-screen "look" of the (low) frame rate, which matches native film.
1-inch Type B Helical Scan or SMPTE B is a reel-to-reel analog recording video tape format developed by the Bosch Fernseh division of Bosch in Germany in 1976. The magnetic tape format became the broadcasting standard in continental Europe, but adoption was limited in the United States and United Kingdom, where the Type C videotape format met with greater success.
By 1976, ferricobalt formulations took over the video tape market, [60] and eventually they became the dominant high-performance tape for audio cassette. [51] Chromium dioxide disappeared from the Japanese domestic market, [ 51 ] although chrome remained the tape of choice for high fidelity cassette duplication among the music labels.
