Distributed video coding using reliability data

A device for processing video data, the device comprising:

• a memory configured to store the video data;
• and
• one or more processors implemented in circuitry and coupled to the memory, the one or more processors configured to:
• obtain video data;
• obtain prediction quality feedback, wherein the prediction quality feedback is based on reliability of estimated pictures generated by a receiving device;
• adapt one or more of video encoding parameters or channel encoding parameters based on the prediction quality feedback;
• perform a video encoding process to generate encoded video data based on one or more pictures of the obtained video data, wherein the video encoding process is controlled by the video encoding parameters;
• perform a channel encoding process on the encoded video data to generate channel encoded data, wherein the channel encoding process is controlled by the channel encoding parameters;
• and
• a communication interface configured to transmit the channel encoded data to the receiving device.

A method of processing video data, the method comprising:

• obtaining error correction data at a receiving device and from a transmitting device, wherein the error correction data provides error correction information regarding a picture of the video data;
• generating, at the receiving device, prediction data for the picture, wherein the prediction data for the picture comprises predictions of blocks of the picture based at least in part on one or more previously reconstructed pictures of the video data;
• generating, at the receiving device, encoded video data based on the prediction data for the picture, wherein the encoded video data includes transform blocks that comprises transform coefficients;
• scaling, at the receiving device, bits of the transform coefficients of the transform blocks based on reliability values for bit positions;
• generating, at the receiving device, error-corrected encoded video data using the error correction data to perform an error correction operation on the scaled bits of the transform coefficients of the transform blocks;
• and
• reconstructing, at the receiving device, the picture based on the error-corrected encoded video data.
