DIGI BETA Format History

The Digital Betacam format records a lossless 2 to 1 DCT-compressed digital component video signal at 10-bit YUV 4:2:2 sampling in NTSC (720×486) or PAL (720×576) resolutions at a bitrate of 90 Mbit/s plus four channels of uncompressed 48 kHz / 20 bit PCM-encoded digital audio. A fifth analog audio track is available for cueing, and a linear timecode track is also used on the tape. It is a popular digital video cassette format for broadcast television use.

Another key element which aided adoption was Sony's implementation of the SDI coaxial digital connection on Digital Betacam decks. Facilities could begin using digital signals on their existing coaxial wiring without having to commit to an expensive re-installation.[4]ic video (AVCHD 3D). The new modes also allowed higher system data rate than existing modes.
