Method and apparatus for transcoding video data

An apparatus for transcoding video data from a first format to a second format comprising:

• a video decoder operative to decode video that is encoded in the first format and produce at least one decoded data block that comprises decoded data for multiple display lines;
• a linear memory address data block populator, operatively coupled to the video decoder, and operative to perform a linear write operation on the decoded data block by controlling storing of the decoded data block in consecutive linear addresses in memory such that a line of memory comprises decoded data for multiple display lines;
• a block data populator operative to fetch the line of memory;
• and
• an encoder, operatively coupled to the block data populator, and operative to re-encode the video data to the second format.

A system comprising:

• an apparatus for transcoding video data from a first format to a second format comprising:
• a video decoder operative to decode video that is encoded in the first format and produce at least one decoded data block that comprises decoded data for multiple display lines;
• a linear memory address data block populator, operatively coupled to the video decoder, and operative to perform a linear write operation on the decoded data block by controlling storing of the decoded data block in consecutive linear addresses memory such that a line of memory comprises decoded data for multiple display lines;
• a block data populator operative to fetch the line of memory;
• an encoder, operatively coupled to the block data populator, and operative to re-encode the video data to the second format from the fetched line of memory;
• a transmitter operative to send the re-encoded video of the second format to a display device;
• a display device comprising:
• a decoder operative to decode the re-encoded video of the second format;
• and
• a display operative to display the decoded video.

A non-transitory storage medium that comprises executable instructions that when executed by an integrated circuit fabrication system, causes the integrated circuit fabrication system to produce an integrated circuit that is operative to:

• decode video that is encoded in a first format and produce at least one decoded data block that comprises decoded data for multiple display lines;
• perform a linear write operation on the decoded data block by controlling storing of the decoded data block in consecutive linear addresses in memory such that a line of memory comprises decoded data for multiple display lines;
• fetch the line of memory and translate the line of memory back into the decoded data block for re-encoding in the second format wherein the block of data comprises data block for multiple display lines;
• and
• re-encode the video data to the second format using the decoded data block that was translated from the fetched line of memory.
