A method and apparatus of processing multimedia data that includes a first section received in error are disclosed. Error distribution information corresponding to the first section may be obtained. One of a plurality of error recovery schemes may be selected based on the error distribution information for the first section. The selection may be based at least on whether a channel switch is detected. The first section may be processed based on the selected error recovery scheme.

Method and apparatus for unified error concealment framework

Techniques for error concealment in multimedia data processing. In an embodiment, error distribution information corresponding to a first section in an access unit is obtained. In another embodiment, a plurality of error recovery schemes may be applied to the first section of the multimedia data based on the error distribution information.

A temperature sensor may sense the temperature of a multi-core processor. In response to the temperature of the multi-core processor exceeding a temperature threshold for the multi-core processor, one or more busy processor cores of the multi-core processor may be power collapsed without reducing clock speed of the multi-core processor.

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.

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.

A method of controlling signal termination includes providing first logic for selectively terminating signals received at a first device on a bidirectional data bus, providing second logic for selectively terminating signals received at a second device on the bidirectional data bus, sending first signals from the first device to the second device on the bidirectional data bus at a first speed, stopping the sending of the first signals, after stopping the sending of the first signals, enabling the second logic and shifting a reference voltage of the second device from a first level to a second level, after enabling the second logic at the second device, sending second signals from the first device to the second device on the bidirectional data bus at a higher speed, and controlling the first logic based on a speed of signals received at the first device on the bidirectional data bus.

Techniques for video encoding and decoding channel switch frames (CSF) to enable acquisition and re/synchronization of the video stream while preserving compression efficiency is provided. Systems and methods to process multimedia data enabling channel switching are presented. The systems generate a CSF with one or more network adaptation layer (NAL) units as a random access point (RAP) frame. Back-to-back frames are transmitted which include the CSF and a non-RAP frame, each having the same frame ID number.

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.
