摘要： An apparatus, system and method are provided for adaptive flow control of layered streaming video over wireless local area networks (WLANs). In one aspect prioritized and adaptive transmission mechanisms are provided based on buffer fullness and discarding visually less important packets so that future visually more important packets can reach the decoder in time. In another aspect, aggregated control is provided for all video applications as well as separate control for each video application.

摘要： This invention provides an efficient standard-compliant system (400 500), apparatus (550) and method for employing the technique of Data Partitioning (DP) to provide acceptable picture quality in digital video transmitted over a wireless home multimedia network (411 510) that may adhere to a layered protocol (300), during conditions of degraded or reduced bandwidth. Such compliance insures that video from a source which incorporates the present invention can be successfully decoded and rendered by any digital video receiver that conforms to the corresponding standard, and that the transmitting equipment can be used with any equipment that adheres to the networking protocol (300).

摘要： A method and apparatus for determining an image noise estimate value in a digital video processing system using only a single video image. In the method and apparatus, SAD values in the video image are calculated. For each SAD value, a determination is made as to whether the SAD value falls within one or more of a plurality of predetermined SAD value ranges, each of which corresponds to a prospective image noise estimate value. The determination is made concurrently for all of the predetermined SAD value ranges. For each one of the SAD value ranges, the number of SAD values that fall within that predetermined SAD value range is counted. The prospective image noise estimate having a count value that meets predetermined criteria is then selected as the image noise estimate value in the digital video processing system.
