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: Methods and systems provide a burst access protocol that enables efficient transfer of data between a first and a second processor via a data interface whose access set up time could present a communication bottleneck. Data, indices, and/or instructions are transmitted in a static table from the first processor and stored in memory accessible to the second processor. Later, the first processor transmit to the second processor a dynamic table which specifies particular data, indices and/or instructions within the static table that are to be implemented by the second processor. The second processor uses the dynamic table to implement the identified particular subset of data, indices and/or instructions. By transmitting the bulk of data, indices and/or instructions to the second processor in a large static table, the burst access protocol enables efficient use of data interfaces which can transmit large amounts of information, but require relatively long access setup times.
