Abstract:
A decoding method for decoding code data comprising audio code data, video code data and data to be discarded during video decoding in an audio/video decoder, said video code data containing start codes indicating said data to be discarded within said video code data, said decoding method comprising:receiving said code data; separating the audio code data from the video code data in an audio/video separator; outputting the audio code data and the video code data from the audio/video separator to a memory for storage; detecting in said audio/video separator said start codes indicating said data to be discarded; storing in a start address register of the audio/video separator a start address within the memory of said data to be discarded, said start address determined by said start codes; turning on a signal in accordance with contents of the audio/video separator start address register and before decoding of said video code data, said signal indicating of the presence of the data to be discarded in said video code data; reading, using a CPU responsive to said signal, said start address from said start address register; reading, using said CPU responsive to said signal, said data to be discarded beginning at said start address; transferring said audio code data and video code data stored in said memory to respective audio and video decoders, said video code data including said data to be discarded; decoding the transferred audio code data and video code data stored in the memory in said respective audio and video decoders; and skipping over, in said video decoder, said data to be discarded contained in said transferred video code data.
