Efficient coding of source video sequences partitioned into tiles

A method of coding video data, comprising:

• partitioning individual frames of a video source into a plurality of tiles of common size;
• coding the frames from the video source according to a video coding protocol including assigning each tile of each frame from the video source its own timestamp according to the video coding protocol, and
• coding content of the tiles of the frames with motion compensation according to the video coding protocol having a respective temporal location corresponding to the tiles's respective timestamp and tiles corresponding to a first tile location over a plurality of frames of the video source are designated as a reference tile for the motion compensation at a first frequency lower than tiles corresponding to a second tile location over the plurality of frames;
• and
• outputting the coded tile data to a channel.
