Abstract: There is disclosed an apparatus for decoding and reproducing moving picture experts group (MPEG) video data, including: an encoded data input unit for receiving MPEG video data and outputting a data signal; a data analyzing unit for receiving the data signal which corresponds to a respective portion of the video data, and deciding whether or not the portion should be decoded; a memory interface unit for outputting a control signal in response to an output signal of the data analyzing unit; an external memory unit for storing the MPEG video data in response to the control signal; a data decoding unit for reading and decoding the MPEG video data stored in the external memory unit and restoring the MPEG data in the external memory unit; and a digital video output unit for reading the decoded data out of the external memory unit and outputting the data at a predetermined time.

Abstract: A circuit for concurrently recording at least two picture signals, each received from at least two different desired television broadcasting channels, on a single video tape in a video tape recorder, and for concurrently reproducing at least two picture signals from a single video tape on which at least two different television broadcasting channels are recorded, in a video tape recorder provided with such video tape. First and second vertical synchronization detection circuits 104, 105 detect each vertical synchronization signal from first and second video signal input terminals VD1, VD2. A recording controller 106 receives the vertical synchronization signals that are detected by the first vertical synchronization detection circuit I04 and the second vertical synchronization signal detection circuit 105, and therefrom produces a first memory control signal, a first mixing control signal and a first selection control signal.
