    • A multiplexing video decoding apparatus for decoding video signals of a plurality of channels and a method therefore are provided. The multiplexing video decoding method receives bit streams, each of which has a plurality of slices, in a plurality of channels and decodes bit streams of the plurality of channels in a multiplexed mode. The multiplexing video decoding method includes sequentially decoding video signals of the bit stream on a slice interval basis in one channel in the plurality of channels, and when the slice has been decoded, switching to decode a slice for each of the other channels; and decoding in a multiplexed mode bit streams of a plurality of channels by repeating the above steps to the following slice of each of the channels. The apparatus includes a plurality of FIFO memories for receiving and processing the multiple bit streams in parallel, a processor for sequentially decoding the bit streams from the FIFO memories, and a video processor to reproduce a video signal.
    • 提供了用于解码多个通道的视频信号的复用视频解码装置及其方法。 复用视频解码方法在多个信道中接收每个具有多个片段的比特流,并以多路复用模式解码多个信道的比特流。 复用视频解码方法包括在多个信道中的一个信道中以片段间隔为基础顺序解码比特流的视频信号,并且当切片被解码时,切换为每个其他信道解码片; 并且通过将上述步骤重复到每个信道的后续片段,以多路复用模式对多个信道的比特流进行解码。 该装置包括用于并行地接收和处理多个比特流的多个FIFO存储器,用于从FIFO存储器顺序地解码比特流的处理器和用于再现视频信号的视频处理器。
