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.

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.

摘要： An Encoder Assisted Frame Rate Up Conversion (EA-FRUC) system that utilizes various motion models, such as affine models, in addition to video coding and pre-processing operations at the video encoder to exploit the FRUC processing that will occur in the decoder in order to improve the modeling of moving objects, compression efficiency and reconstructed video quality. Furthermore, objects are identified in a way that reduces the amount of information necessary for encoding to render the objects on the decoder device.
