Abstract

A system and method for processing image signals, including a signal dividing unit for dividing input image signals per frame into a first plurality of sub-blocks with a second plurality of the sub-blocks being included in the horizontal direction and each of the sub-blocks having the height equal to that of at least one macro-block, a recording unit for recording thus divided input image signals, a third plurality of encoding units each for encoding the divided and recorded input image signals in units of sub-block to be outputted as an encoded stream with the number of the encoding units equal to that of the sub-blocks in the horizontal direction, a further recording unit for recording the encoded stream in units of sub-block, and a stream conversion unit for outputting a video stream after rearranging the order of the encoded and recorded stream.

Description

technical field [0001] The present invention relates generally to signal processing systems and methods, and more particularly to systems and methods for processing image signals. Background technique [0002] In recent years, the trend of large-size and high-resolution display devices has become more and more obvious. Along with this display device development trend, it is also necessary to improve the ability of encoding processing and decoding processing of images to be displayed on the display device (for example, refer to Japanese Unexamined Patent Application Publication Nos. 2001-346201, 2004-356857, 2008 -54183, and Heisei 10 (1998)-234043). In order to increase the processing capability of an MPEG (Moving Picture Experts Group) decoder, for example, it is necessary to increase the calculation capability of a processing unit for performing decoding processing, and also increase the bandwidth between external memories for storing decoded picture data ( transmission ...
