Cross-layer cross-channel sample prediction

A computer-implemented method for video coding, comprising:

• reconstructing a reference sample for a reference channel in a reference layer of video data;
• determining a target prediction sample for a target channel in a target layer based at least in part on the reference sample via cross-layer cross-channel prediction, wherein the target channel is a different channel than the reference channel;
• and
• coding the target channel based at least in part on the target prediction sample.

A system for video coding on a computer, comprising:

• a display device configured to present video data;
• one or more processors communicatively coupled to the display device;
• one or more memory stores communicatively coupled to the one or more processors;
• a sample reconstruction logic module of the video coder communicatively coupled to the one or more processors and configured to reconstruct a reference sample for a reference channel in a reference layer of video data;
• and
• a cross-layer cross-channel prediction logic module of a video coder communicatively coupled to the sample reconstruction logic module and configured to determine a target prediction sample for a target channel in a target layer based at least in part on the reference sample via cross-layer cross-channel prediction, wherein the target channel is a different channel than the reference channel.

A system comprising:

• an antenna configured to receive an encoded bitstream of video data;
• and
• a video decoder communicatively coupled to the antenna and configured to decode the encoded bitstream, wherein the video decoder is configured to:
• reconstruct a reference sample for a reference channel in a reference layer of video data;
• determine a target prediction sample for a target channel in a target layer based at least in part on the reference sample via cross-layer cross-channel prediction, wherein the target channel is a different channel than the reference channel;
• and
• decode the target channel based at least in part on the target prediction sample.
