APPARATUS AND METHOD FOR ENCODING IMAGE CAPABLE OF PARALLEL PROCESSING IN DECODING AND APPARATUS AND METHOD FOR DECODING IMAGE CAPABLE OF PARALLEL PROCESSING

摘要

PURPOSE: An apparatus and a method for encoding an image capable of parallel processing in decoding and an apparatus and a method for decoding an image capable of parallel processing are provided to decode compression data belonging to each data group by entropy decoders in parallel. CONSTITUTION: A macro block encoder(210) performs integer conversion and quantization of macro blocks configuring the original image frame to output quantization coefficient data. An entropy encoder(220) performs entropy encoding of the quantization coefficient data to output compression data. A data length calculator(240) generates data groups made of continuous compression data and calculates the length of the data group. A bit stream generator(230) generates an encoded bit stream from the compression data and includes the length of the data group in a header of the bit stream.
