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: The disclosure is directed to a multi-channel encoder. The multi-channel encoder is configured to generate an encoded data stream. The multi-channel encoder includes a plurality of channel encoders, and a processor configured to allocate time slots in the encoded data stream to each of the channel encoders to vary the rate of data provided by each of the channel encoders into the encoded data stream.

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.
