Abstract

Transmitting compressed variable bit rate video with traditional constant bit-rate (CBR) service for continuous playback requires a large buffer at the viewer's side. In this paper, we study a new CBR transmission scheme, called PCR-assist CBR (PCBR) which employs the Program Clock References (PCR) embedded in the MPEG-2 Transport Streams to reduce the buffer requirement. The PCBR scheme uses PCRs to examine its transmission regularly. It holds up the transmission if it is ahead of schedule. Based on the experimental results with video traces, the PCBR scheme reduces the buffer requirement at the cost of higher transmission rate.
