Data parallel processing method and apparatus in image decoder

摘要

In order to efficiently perform parallel processing of data without increasing the amount of buffers required for data parallel processing in an image decoder, a frame of an image signal encoded through a video encoder is encoded, A data parallel processing apparatus in an image decoder that performs parallel processing on a bit stream, the apparatus comprising: a decoding operable to group encoded bit strings of the parallel structure frame in local s and to group the data grouped in the local s into a plurality of The image data signal can be efficiently converted into an encoded bit stream without generating a full or empty phenomenon of the buffer while suppressing an increase in the capacity of the buffer required for data parallel processing in the image decoder. Can be processed in parallel.
