Abstract: Innovations in encoder-side options for intra block copy (“BC”) prediction mode facilitate intra BC prediction that is more effective in terms of rate-distortion performance and/or computational efficiency of encoding. For example, some of the innovations relate to concurrently performing block vector (“BV”) estimation and making block splitting decisions for a block. Other innovations relate to selectively merging blocks into a larger block during BV estimation.

Abstract: A processing for a first pixel in a picture comprises obtaining a lower limit of a first color component of the first pixel in a first color space based on a distance between a color of the first pixel and a first distorted version of the color in a second color space. An upper limit of the first color component in the first color 5 space is obtained based on a distance between the color and a second distorted version of the color in the second color space. A filtered value is obtained of the first color component and which is equal to or larger than the lower limit and equal to or lower than the upper limit. The processing results in filtered values that are cheaper to encode but that are visibly undistinguishable from the original colors of the pixels.

Abstract: A technique for synchronizing video receivers with a video stream already in progress includes caching a key frame in a transport protocol component of a video communication system and providing the key frame on demand to any receiver attempting to join the stream and/or to rejoin the stream after an error, such as a dropped packet. Once a receiver obtains the key frame, the receiver requests that the source of the video stream issue a new sync-point frame, where the sync-point frame depends on the key frame but on no other frame for its content. The receiver may then proceed to display rendered video beginning with the sync-point frame.
