Abstract:
1. A signal processing system, comprising: a signal dividing unit configured to divide input image signals per frame into a first plurality of sub-blocks, each sub-block having a height in a vertical direction equal to that of at least one macro-block, and a second plurality of said sub-blocks being arranged in a horizontal direction; a first recording unit configured to record the divided input image signals in units of the sub-block to form divided and recorded input image signals; a third plurality of encoding units each configured to encode the divided and recorded input image signals in units of the sub-block to be outputted as an encoded stream, a number of the third plurality of encoding units being equal to a number of the sub-blocks divided by the signal dividing unit in the horizontal direction; a second recording unit configured to record the encoded stream in units of the sub-block to form an encoded and recorded stream; and a stream conversion unit configured to output a video stream after rearranging the encoded and recorded stream such that an order of the output video stream coincides with the order of the input image signals.
