发明名称 DROPOUT COMPENSATOR AND LUMINANCE AVERAGER WITH ''SHARED'' DELAY
摘要 <p>A video disk player, arranged to reproduce a video signal from a single recorded field, operates with fewer components by ''sharing'' a one-line delay element (42) with a dropout compensator (36) and a luminance averager (44). In the absence of a dropout, the output video signal is taken from the one-line delay element (42). When a dropout is detected, the delayed video signal is recirculated to the input of the delay element (42). Since the video signals at both the input and the output of the delay element (42) are free of dropouts, they are provided to the line averager (44) for generating an interpolated signal for an interlaced (second) field.</p>
