EFFICIENT BANDWIDTH USAGE DURING VIDEO COMMUNICATIONS

Abstract:

Methods, systems, and devices for efficient bandwidth usage during video communications are described. A device may estimate first motion vector information of a frame associated with a set of video frames based on a reference frame associated with the set of video frames. The reference frame may include a preceding intra-frame, a predicted-frame, or a bi-directional predicted frame in a video frame sequence. In some aspects, the device may estimate second motion vector information of the frame associated with the set of video frames based on a learning model, compare the first motion vector information and the second motion vector information using the learning model, and generate a set of video packets carrying the set of video frames including the video frame based on the comparing. In some examples, the video frame may be generated at the device or at a second device in wireless communication with the device.
