<p>PURPOSE:To simultaneously receive the picture signals of plural series through the use of the same decoding circuit by decoding the picture-multiplexed signal, and interpolating a picture element, omitted at a sending side, into the picture signal of each series, after demultiplexing it, and besides, converting it into a television signal. CONSTITUTION:A time division multiplexing picture signal, inputted to a picture decoding circuit 1, is decoded into a multiplexed original picture signal, and after it is inputted to the picture switching circuit 4 of a picture demultiplex circuit 2, it is demultiplexed into the picture of every series by a demultiplex control circuit 3, through the inverse operation of a picture multiplexing at the sending side, and stored in each buffer 5-5, and outputted to the circuit of a sequential step at a regulated timing. Each picture signal, demultiplexed and inputted to a picture interpolation circuit 6 of the sequential step, is interpolated with the picture element by the demultiplex control circuit 3, according to the ratio of each multiplexed picture, and outputted. Each picture signal A-D, regenerated in such a way, is given a conversion into each television signal at a picture signal afterprocessing circuit 7, and outputted being analogized. Thus, the picture signal of the plural series can be simultaneously picture-reproduced by the same decoding circuit.</p> |
