HDTV SERIAL INTERFACE SYSTEM

This paper describes a new serial interface system which uses conventi onal 75 ohm coaxial cable. Typically parallel 25 pin cable and connect ors are used to transfer and receive the data between digital systems such as HDVCR, D3 VTR and HDTV Receiver. The coaxial cable is more des irable for consumer product applications and also for studio applicati ons where long signal paths and switching are required. This serial da ta transfer technique is thoroughly tested and utilized in the data tr ansmission/reception between systems more than 200 feet apart. It is a lso cost effective because it does not require RF PLL, scrambling, and NRZI hardware.
