高機能映像自動モニターの開発

概要

A high-performance automatic video signal detecter has been developed as a key device for next-generation signal monitoring system. It detects abnormal signals that cannot be detected by the conventional detecter, which only detects failures of video signals by sensing decrease in the level of synchronous signals. The new system detects such new items as picture freeze, cut off (black level) of video signals, and clipping of the black level of video signals. Regarding synchronous signals, it detects deviations from the RS-170A rating such as irregular synchronous signals and slippage of SCH as well as the decrease in level detected by the conventional system. Detection is achieved with HD-PICOT, a DSP capable of processing video signals in real time.
