An analogue component VTR system for SD television, using a half-inch cassette – very similar to the domestic Betamax. This was developed by Sony and is marketed by them and several other manufacturers. Although recording the Y, R-Y and B-Y component signals onto tape, many machines are operated with coded (PAL or NTSC) video in and out.

The system was developed to offer models for the industrial and professional markets as well as full luminance bandwidth (Betacam SP), PCM audio and SDI connections.
