Abstract
An analog data stream is monitored as a series of blocks. A ring memory array digitally stores the blocks and repetitively loads and unloads the blocks. A freeze switch disables loading of the latest blocks. A block identifier puts out a unique block identification value for each block put out by the memory and is responsive to the freeze switch, so that when loading stops, each block put out bears the same identification value. The invention is particularly well suited to handling of television frames.
