Paper Abstract

In this paper, we introduce a priority-based technique for the delivery of compressed prerecorded video streams across best-effort networks. This technique uses a multi-level priority queue in conjunction with a delivery window to help smooth the video frame rate delivered to the end user while allowing it to easily adapt to changing network conditions. Compared with current approaches, our priority-based approach has several advantages. First, it acts more globally by ensuring that a minimum frame rate for the window interval has been delivered before sending enhancement layers. Second, this approach is much simpler to implement than other frame smoothing algorithms that have been presented for the delivery of stored video across best- effort networks. Finally, this approach is directly applicable for the shaping of MPEG-based video encodings with frame dependencies.
