ABSTRACT:
A method and apparatus for encoding multi-channel video signals is disclosed. In order for multiple of input channels to share hardware resources, one input channel is selected and multi-channel input video signals are stored through memory block switching. Multiplexer (1), video decoder (3), and digital video multiplexer (9) participate in selecting one input channel and memory block switching section (17) switches input and restoring frames to and/or from memory (27). For stabilizing frame rate under the conditions of multiple input channels, input channel sequence is determined by synchronization signal separator (7) and priority detection and channel switching section (13). In accordance with the present invention, multi-channel video signals are encoded into MPEG by using the conventional single channel MPEG encoder (15).
