ABSTRACT:
A frame combining apparatus, having a plurality of decoding means for decoding frame data for each of a plurality of sub-frames through a decoding process opposite to a coding process when a plurality of coded data streams obtained by coding frame data of a frame divided into a plurality of sub-frames are input, a synchronizing means for generating external synchronizing data for defining output timings of decoded outputs from a plurality of decoding means, and a delaying means for generating more than one external synchronizing data delayed by a delay time corresponding to a plurality of sub-frames in response to the division of a frame and to give the external synchronizing data from the synchronizing means and external synchronizing data having a delay time corresponding to the divided sub-frames out of more than one delayed external synchronizing data to decoding means corresponding to the sub-frames, respectively.
