Proposal for Error Detection and Handling in Studio Equipment

By its nature, video equipment which is digital, rather than analog, has greater potential for “minor” failures which result in signal distortions which are visually obnoxious. Analog equipment is more likely to fail gracefully and subtly when it malfunctions. On the other hand, digital equipment has a potential for self-testing, verification, monitoring, and remote diagnosis that is not possible with analog equipment, by its very nature. — A proposal for exploiting this potential for error detection, self-diagnosis, and complete system monitoring in digital equipment is described. The proposal includes generating CRC words which are inserted into the digital video signal and used for error detection. Additional error information is also inserted into the signal which allows appropriate monitoring equipment to detect the occurrence of any bit errors, and identify and isolate failing video equipment.
