Tutorial: Diagnostics for High-Speed Video Circuitry: Application to a Digital Videotape Recorder
It is generally accepted that complex digital equipment should include some form of diagnostics to assist in the location of fault conditions. Signature analysis techniques, when integrated into the hardware and software of a digital videotape recorder (DVTR) can efficiently test and greatly facilitate troubleshooting digital circuitry with minimal circuit overhead. In addition, other techniques may be incorporated to improve the testability and reliability of the system, such as the inclusion of special test signals in the video and audio paths. The most effective systems are those that are completely self-contained and do not require the use of any external equipment. The above-mentioned diagnostic techniques have been successfully integrated in a composite DVTR.
