Abstract
The disclosure is directed to techniques for picture-in-picture (PIP) processing for video telephony (VT). According to the disclosed techniques, a local video communication device transmits PIP information to a remote video communication device. Using the PIP information, the remote video communication device applies preferential encoding to non-PIP regions of video transmitted to the local video communication device.
Claims38
A method comprising:
- encoding video to be transmitted to a remote video communication device based on remote picture-in-picture (PIP) information, wherein encoding includes preferentially encoding regions of the video that are not covered by a remote PIP region, and wherein preferentially encoding includes skipping encoding of regions of the video that are covered by the remote PIP region;
- and
- transmitting the video and PIP information to the remote video communication device.
A video communication device comprising:
- an encoder that encodes video to be transmitted to a remote video communication device based on remote picture-in-picture (PIP) information, wherein the encoder preferentially encodes regions of the video that are not covered by a remote PIP region, and wherein the preferentially encoding includes the encoder skipping encoding of regions of the video that are covered by the remote PIP region;
- and
- a signaling module that sends PIP information to the remote video communication device.
A computer program product, the computer program product including a non-transitory computer readable medium storing computer-executable instructions that when executed cause a processor to:
- encode video to be transmitted to a remote video communication device based on remote picture-in-picture (PIP) information, wherein the instructions that cause the processor to encode include instructions that cause the processor to preferentially encode regions of the video that are not covered by a remote PIP region, and further wherein the instructions that cause the processor to preferentially encode include instructions that cause the processor to skip encoding of regions of the video that are covered by the remote PIP region;
- and
- transmit the video and PIP information to the remote video communication device.
A system comprising:
- means for encoding video to be transmitted to a remote video communication device based on remote picture-in-picture (PIP) information, wherein the means for encoding preferentially encodes regions of the video that are not covered by a remote PIP region, and wherein preferentially encoding includes skipping encoding of regions of the video that are covered by the remote PIP region;
- and
- means for transmitting the video and PIP information to the remote video communication device.
