Abstract
The disclosure is directed to techniques for region-of-interest (ROI) processing for video telephone (VT) applications. According to the disclosed techniques, a recipient device defines ROI information for video information transmitted by a sender device, i.e., far-end video information. The recipient device transmits the ROI information to the sender device. Using the ROI information transmitted by the recipient device, the sender device applies preferential encoding to an ROI within a video scene. In this manner, the recipient device is able to remotely control ROI encoding of far-end video information by the sender device.
Claims54
A method comprising:
- receiving information from a remote device specifying a region of interest (ROI) within near-end video encoded by a local device and received by the remote device;
- and
- encoding the near-end video based on the ROI to enhance image quality of the ROI relative to non-ROI areas of the video.
A video encoding device comprising:
- a region of interest (ROI) engine that receives information from a remote video communication device specifying a region of interest (ROI) within near-end video transmitted to the remote device;
- and
- a video encoder that encodes the near-end video to enhance image quality of the ROI relative to non-ROI areas of the video.
A computer-readable medium comprising instructions to cause a processor to:
- receive information from a remote device specifying a region of interest (ROI) within near-end video encoded by a local device and received by the remote device;
- and
- encode the near-end video to enhance image quality of the ROI relative to non-ROI areas of the video.
A method comprising:
- generating information specifying a region of interest (ROI) within far-end video transmitted by a remote device and received by a local device;
- and
- transmitting the information to the remote device for use in encoding the far-end video based on the ROI to enhance image quality of the ROI relative to non-ROI areas of the video.
A video encoding device comprising:
- a region of interest (ROI) engine that generates information specifying a region of interest (ROI) within far-end video received from a remote device;
- and
- a video encoder that encodes near-end video and transmits information specifying the ROI with the encoded near-end video for use by the remote device in encoding the far-end video based on the ROI to enhance image quality of the ROI relative to non-ROI areas of the far-end video.
