    摘要: A method and apparatus for multi-layer integration for use in error recovery is disclosed. An error is detected in a multimedia data based on a first layer protocol and the detected error in the multimedia data is concealed based on a second layer protocol. In one aspect, the error in a multimedia data is detected based on a communication layer protocol and controlled based on a transport layer protocol. An error distribution of the controlled error is then determined based on a sync layer protocol and the detected error in the multimedia data is concealed based on an application layer protocol. In another aspect, a method and apparatus for multimedia data processing comprises error recovery as well as scalability. Finally, a method and apparatus as disclosed allows processing of multimedia stream by receiving multiple streams of encoded multimedia data, performing error recovery on an erroneous portion of a stream, and reconstructing the multimedia data from the multiple streams.

    摘要: This disclosure relates to techniques for performing display mode based video encoding to reduce power consumption in a source device of a Wireless Display (WD) system. More specifically, the techniques enable the source device to select an encoding process based on whether the video data to be encoded is in a static display mode or a dynamic display mode. For example, when the video data is in the static display mode, the source device selects a static encoding process that reduces an amount of video data processing and compression, which in turn reduces power consumption at the source device. When the video data is in the dynamic mode, the source device may select a conventional dynamic encoding process. The source device encodes the video data according to the selected encoding process, and transmits the encoded video data to one or more sink devices in the WD system for display.
