ABSTRACT:
In a television receiver, a demultiplexer for a high definition multiplexed analog component television signal provides samples of each component signal. A group of samples for each component signal is selected according to the aspect ratio of the television receiver display, and according to the aspect ratio of the picture contained in the high definition multiplexed analog signal so that the selected group is the one that provides picture information which fits the aspect ratio of the display. The selected samples for one scan line are first stored during the active scan line time and then read out sequentially during the subsequent scan line time. The stored samples of each component signal are read out sequentially during substantially the same time period to provide the required Y, U, V signals. A similarly designed demultiplexer may be used to process an extended aspect ratio frequency multiplexed signal such as a high definition NTSC-formatted signal.
