D3 Digital video


A VTR standard using 1/2” tape cassettes for recording digitised composite (coded) PAL or NTSC signals sampled at 8 bits.

Cassettes are available for 50 to 245 minutes.

Since this uses a composite signal the characteristics are generally as for D2 except that the 1/2” cassette size has allowed a full family of VTR equipment to be realised in one format, including a camcorder.
