Decode processing apparatus, decode processing method, data distribution program, and decode processing program

A decode processing method comprising:

• in a decode processing apparatus:
• splitting a screen of encoded moving picture data into a plurality of vertical bands;
• distributing each of the plurality of vertical bands to a plurality of at least three processors;
• decoding the plurality of vertical bands of the encoded moving picture data in units of a predetermined processing block by the at least three processors, wherein a communication of decoded moving picture data between the at least three processors occurs when a leftmost processing block and a rightmost processing block in each of the plurality of vertical bands is decoded;
• generating picture data of the screen based on the decoded moving picture data by the at least three processors, wherein
• a first temporary storage and a second temporary storage are interposed between each pair of processors of the at least three processors, wherein the first temporary storage communicates the decoded moving picture data from
• a first processor of the plurality of at least three processors to a second processor, immediately following the first processor, of the at least three processors, and
• the second temporary storage communicates the decoded moving picture data from the second processor to the first processor, and wherein
• the first temporary storage and the second temporary storage for each pair of processors of the at least three processors are different.

A non-transitory computer readable medium having at least one code section for performing decode processing of encoded moving picture data, the at least one code section being executable by a computer for causing the computer to perform steps comprising:

• splitting a screen of the encoded moving picture data into a plurality of vertical bands;
• distributing the encoded moving picture data belonging to each of the plurality of vertical bands to a plurality of processors, wherein a communication of decoded moving picture data between the plurality of processors occurs when a leftmost processing block and a rightmost processing block in each of the plurality of vertical bands is decoded, wherein
• a first temporary storage and a second temporary storage are interposed between each pair of processors of the plurality of processors, wherein
• the first temporary storage only communicates the decoded moving picture data from a first processor of the plurality of processors to a second processor, immediately following the first processor, of the plurality of processors, and
• the second temporary storage only communicates the decoded moving picture data from the second processor to the first processor, and wherein
• the first temporary storage and the second temporary storage for each pair of processors of the plurality of processors are different.

A non-transitory computer readable medium executed by each of a plurality of computers which are incorporated in a decode processing apparatus having at least one code section for performing decode processing of moving picture data, the at least one code section being executable by a computer of the plurality of computers for causing the computer to perform steps comprising:

• when performing decode processing of each processing block, causing a first computer of the plurality of computers to use processing results of processing blocks positioned left, top left, and top right of a processing block of interest;
• if a vertical band of the moving picture data is positioned left of an allotted vertical band and if a leftmost processing block of an allotted vertical band is to be processed, causing the first computer to receive the processing result of the processing block positioned left of the processing block of interest from a second computer of the plurality of computers caused to process the another vertical band positioned left;
• causing the first computer to perform decode processing using the processing result of the processing block positioned left and the processing result of the processing block positioned left received during the processing of blocks in the upper row;
• causing the first computer to transmit the result of the decode processing to the second computer caused to process the another vertical band positioned left;
• if another vertical band is positioned right of the allotted vertical band and if the rightmost processing block of the allotted vertical band is to be processed, causing a computer of interest of the plurality of computers to receive the processing result of the processing block positioned right of the processing block of interest from the second computer caused to process the another vertical band positioned right;
• causing the computer of interest to perform decode processing using the processing result of the processing block positioned top right;
• and
• causing the computer of interest to transmit the result of the decode processing to the second computer caused to process the another vertical band positioned right, wherein
• communication of decoded moving picture data between the plurality of computers occurs when a leftmost processing block and a rightmost processing block in each vertical band is decoded, and wherein
• a first temporary storage and a second temporary storage are interposed between each pair of computers of the plurality of computers, wherein
• the first temporary storage only communicates the decoded moving picture data from one computer of the plurality of computers to another computer, immediately following the one computer, of the plurality of computers, and
• the second temporary storage only communicates the decoded moving picture data from the another computer to the one computer, and wherein
• the first temporary storage and the second temporary storage for each pair of computers of the plurality of computers are different.
