WIRELESS DISPLAY SHARING WITH DYNAMIC RESOLUTION SWITCHING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240333946 titled 'WIRELESS DISPLAY SHARING WITH DYNAMIC RESOLUTION SWITCHING
The abstract describes a video source device for wireless display sharing that can dynamically switch between encoding a full-frame video into a lower resolution bitstream and a sub-frame video into a higher resolution bitstream based on available wireless transmission bandwidth and video complexity.
- Encoder can switch between encoding full-frame video into a lower resolution bitstream and sub-frame video into a higher resolution bitstream.
- Processing circuitry decides encoding based on available bandwidth, pixel changes, spatial and temporal complexity, and category of region change.
- Transmitter wirelessly transmits both bitstreams to a video sink device.
Potential Applications: - Wireless display sharing in offices, classrooms, and homes. - Video conferencing systems. - Screen mirroring for presentations and entertainment purposes.
Problems Solved: - Efficient use of wireless bandwidth. - Improved video quality based on content complexity. - Seamless switching between full-frame and sub-frame encoding.

Original Abstract Submitted
a video source device for wireless display sharing, including: 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.
