A video demultiplexer and video decoder include features for efficient video data recovery in the event of channel error.

In particular, the boundary information permits the error to be associated with a small segment of data. The video decoder conceals data from the beginning of the segment of data, rather than an entire slice or frame in which the segment resides. In this manner, the video decoder provides efficient data recovery, limiting the loss of useful data that otherwise would be purposely discarded for concealment purposes.

Efficient video slicing

The disclosure is directed to a video slicing technique that promotes low complexity, bandwidth efficiency and error resiliency. A video encoder places an RM close to the beginning of each logical transmission unit (LTU) so that all but a very small end segment of each video slice fits substantially within an LTU. Instead of requiring placement of RMs exactly at the LTU boundaries, a video encoder applies an approximate alignment technique. Video slices are encoded so that RMs are placed close to the beginning of each LTU, e.g., at the end of the first MB falling within the LTU. A portion of the last MB from the preceding slice carries over into the next LTU. Loss of an LTU results in loss of virtually the entire current slice plus a very small portion of the previous slice.

Apparat og fremgangsmåte for å utføre talesignalkompresjon ved hjelp av koding ved forskjellig takt, av tidsintervaller eller rammer med digitaliserte talesampler (10).

Video source rate control for video telephony

The disclosure relates to techniques for video source rate control for video telephony (VT) applications. The source video encoding rate may controlled using a dual-buffer based estimation of a frame budget that defines a number of encoding bits available for a frame of the video. The dual-buffer based estimation technique may track the fullness of a physical video buffer and the fullness of the virtual video buffer. The source video encoding rate is then controlled based on the resulting frame budget. The contents of the virtual buffer depend on constraints imposed by a target encoding rate, while the contents of the physical buffer depend on constraints imposed by varying channel conditions. Consideration of physical video buffer fullness permits the video source rate control technique to be channel-adaptive. Consideration of virtual video buffer fullness permits the video source rate control technique to avoid encoding excessive video that could overwhelm the channel.
