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: 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.
