Abstract :
This paper describes the revised versions of the three recording/playback interface systems from the previous ones. Modifications were required to meet the current HDTV transport data formats which were significantly changed in accordance with the Grand Alliance (GA) specification. The interface is also modified to accept both 8 VSB and 16 VSB modes. It has three types of interface application: the first interface is for the GA-HDTV transmitter to D3 digital VTR, the second is for the GA-HDTV receiver to HD-VCR and the third is for the HD-VCR to D3 VTR. The interface hardware was fully developed and used for the GA-HDTV systems laboratory testing in April, 1995 at ATTC and field testing in Charlotte, North Carolina
