Abstract: In implementations of the subject matter described herein, there are provided a method and apparatus for real time screen sharing. During the screen sharing of two devices, if a certain condition is satisfied for an image encoded by a first device and an image decoded by a second device, the first device pauses image processing images.

After the first device resumes image processing, the adjusted parameter is used to encode a new image captured on the first device. According to implementations of the subject matter described herein, a transmission code rate during the screen sharing can be controlled according to the pause time of pausing image processing. The implementations of the subject matter described herein can reduce transmission latency of screen sharing, thereby effectively ensuring the user experience.

Abstract: Innovations in unified intra block copy (“BC”) and inter prediction modes are presented. In some example implementations, bitstream syntax, semantics of syntax elements and many coding/decoding processes for inter prediction mode are reused or slightly modified to enable intra BC prediction for blocks of a frame. For example, to provide intra BC prediction for a current block of a current picture, a motion compensation process applies a motion vector that indicates a displacement within the current picture, with the current picture being used as a reference picture for the motion compensation process. With this unification of syntax, semantics and coding/decoding processes, various coding/decoding tools designed for inter prediction mode, such as advanced motion vector prediction, merge mode and skip mode, can also be applied when intra BC prediction is used, which simplifies implementation of intra BC prediction.
