A VTR (video tape recorder) format using the same cassette as D3 but recording component signals sampled to CCIR 601 recommendations at 10 bit resolution. With internal decoding D5 VTRs can play-back D3 tapes and provide component outputs. Uncompressed component digital video recorders.
Being a non-compressed component digital video recorder means D5 enjoys all the performance benefits of D1, making it suitable for high-end post production as well as more general studio use. Besides servicing the current 625 and 525 line TV standards the format has provision for HDTV recording by use of about 4:1 compression (HD D5).
