Abstract
An advanced multiplexer designed and optimized for next generation on-demand video distribution is described. Features and capabilities include low-latency client interactions, quality of service management, session based encryption management, support for multiple video formats, and support for multiple video decoding standards. Indicators are embedded in new video segments to identify start-of-segment transition points, enabling rapid transitions from one video segment to another. Low-latency operation is achieved by rapid switching, and by coordinating flushing of video buffers and buffer restoration.
