The present invention describes a new digital video tape recorder apparatus and method in which video channels are simultaneously recorded in a recording mode, and in which any of the recorded video channels is reproduced when in a reproducing mode. The apparatus includes a first selector unit for generating signals for identifying one or more channels containing video signals to be recorded. A receiver sends the channel identifying signals to a transmitter, which, in turn, uses the channel identifying signals to selectively identify the channels to be transmitted to the receiver. The transmitter compresses and multiplexes the video signals of the channels selected by the receiver. The receiver receives the compressed and multiplexed signals, and records and stores the received signals. A demultiplexer selectively demultiplexes the channels transmitted to the receiver, and a memory records or stores the signals in the demultiplexed channels. A second selector unit selects one or more recorded channels for reproduction, such that a decompressor decompresses the signals of the channels selected by the second selector unit. The tape recorder apparatus further includes a decompressor associated with one or more of the recording media for pre-decompressing a predetermined amount of leading signals. In another embodiment, the selection signals from the first selector unit are fed back to the transmitter for determining the number of selected channels, so as to automatically adjust the channel bandwidth of the video channels.
