Betamax (also known as Beta, as in its logo) is a consumer-level analog recording and cassette format of magnetic tape for video, commonly known as a video cassette recorder. It was developed by Sony and was released in Japan on May 10, 1975, [ 1 ] followed by the US in November of the same year.
U-matic was also available in a smaller cassette size, officially known as U-Matic S. U-Matic S was developed as a more portable version of U-Matic, to be used in smaller-sized S-format recorders such as the aforementioned Sony VO-3800, as well as the later VO-4800, VO-6800, VO-8800, BVU-50, BVU-100, BVU-110, and BVU-150 models from Sony, among ...
In 1999 Sony backported the DV recording scheme to 8-mm systems, creating Digital8. By using the same cassettes as Hi8, many Digital8 camcorders were able to play analog Video8 or Hi8 recordings, preserving compatibility with already recorded analog video tapes. Sony introduced another camcorder cassette format called MicroMV in 2001. Sony was ...
Its cartridges, resembling larger versions of the later VHS cassettes, used 3/4-inch (1.9 cm)-wide tape and had a maximum playing time of 60 minutes, later extended to 80 minutes. Sony also introduced two machines (the VP-1100 videocassette player and the VO-1700, also called the VO-1600 video-cassette recorder) to use the new tapes.
The L-size cassette can be used in both Sony and Panasonic equipment; nevertheless, they are often called DVCAM tapes. Older Sony decks would not play large cassettes with DVCPRO recordings, but newer models can play these and M-size DVCPRO cassettes. These cassettes come in lengths up to 276 minutes of DV or HDV video (or 184 minutes for DVCAM).
Additionally, IMX ensures that each frame has the same exact size in bytes to simplify recording onto video tape. Video recorded in the IMX format is compliant with CCIR 601 specification, with eight channels of audio and timecode track. It lacks an analog audio (cue) track as the Digital Betacam, but will read it as channel 7 if used for playback.
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 ...
