Abstract
An integrated circuit receives a compressed input stream having a first compression format. A media processing module converts the compressed input stream to an intermediary compression format for processing without fully decompressing the compressed input stream. After processing, a compressed output stream having a second compression format is generated from the intermediary compression format. Processing is dynamically adjusted responsive to changing network conditions. Optionally, the integrated circuit can receive live, raw video, partially encode it into the intermediary compression format, process it with the media process module as well as take the intermediary compression format, decode and output the live, raw video.
