Videodisc and player for HDMAC

High definition television standards such as HDMAC require high density storage media. The videodisc medium fulfils this requirement: high-density storage and fast retrieval are achieved. A description of the transparent modulation system for a HDTV video-signal is given. It will be shown that the HDMAC format as developed in the Eureka project is the best solution for HDTV signals on a videodisc. A prototype HDMAC videodisc player is also described
