Record/playback interfaces: DSC-HDTV, HD-VCR and D3 VTR

Three interface systems used to record and play back the compressed digital data from the DSC-HDTV (high-definition television) system are described. The first interface is for recording the compressed data from the DSC-HDTV to the HD-VCR system; the second is for the DSC-HDTV to the D3 digital VTR (video tape recorder); and the third is for the HD-VCR to the D3 VTR. The interface hardware was fully developed, and the feasibility of recording and playing back the digital data from the DSC-HDTV to both the HD-VCR and the D3 machine was demonstrated.<>
