PROBLEM TO BE SOLVED: To reproduce video from other angles, at a later. SOLUTION: A tuner 12 selects a signal of a prescribed channel from an input signal from an antenna 10 and applies the selected signal to a system decoder 14. The system decoder 14 writes data of a sub-channel not usually selected for an output among outputs of the tuner 12 to a memory circuit 26 and gives video data of a selected sub-channel or angle to a video decoder 16 and to apply audio data to an audio decoder 22. The memory circuit 26 consists of a ring memory structure. The decoders 16, 22 decode data from the system decoder 12 respectively to apply the decoded data to a display device 20 and a speaker 24. When data temporarily stored in the memory circuit 26 is reproduced, the system decoder 14 separates the data from the memory 26 into video data and audio data and supplies them to the decoders 16, 22 respectively.
