1. A video source device for wireless display sharing, comprising:
an encoder operable to dynamically switch between encoding a video full-frame into a first bitstream at a first resolution, and a video sub-frame into a second bitstream at a second resolution, wherein the second resolution is higher than the first resolution;
processing circuitry operable to decide between encoding the video full-frame and encoding the video sub-frame based on an amount of available wireless transmission bandwidth, a number of pixels in a changed region of the video full-frame, spatial complexity of a changed region of the video full-frame, temporal complexity of a changed region of the video full-frame, or a category of region change of the video full-frame; and
a transmitter operable to wirelessly transmit the first bitstream and the second bitstream to a video sink device.
