Abstract: 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.

Abstract: 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.

Abstract: A method of video coding that includes encoding resynchronization point information, where the resynchronization point information includes information identifying a location of a resynchronization point within a section of a video bitstream and information for decoding the bitstream following the resynchronization point. Also, a method for decoding digital video that includes receiving an encoded bitstream including resynchronization point information, where the resynchronization point information includes information identifying a location of a resynchronization point and information for decoding the bitstream following the resynchronization point, decoding the received bitstream, and locating the resynchronization point in the bitstream based on the resynchronization point information.

Abstract: Se proveen técnicas para codificación y decodificación de cuadros para cambio de canal (CSF) de video para habilitar la adquisición y re/sincronización de flujo de video al tiempo que se conserva la eficiencia de compresión. Se presentan sistemas y métodos para procesar datos de multimedia que habiliten el cambio de canal. Los sistemas generan un CSF con una o más unidades de capa de adaptación de red (NAL) como un cuadro de punto de acceso aleatorio (RAP). Se transmiten cuadros continuos los cuales incluyen al CSF y un cuadro de tipo no RAP, teniendo cada uno en mismo número de identificación de cuadro.
