“…We focus on the issue of efficient bandwidth allocation for the delivery of pre-recorded video. Other related issues such as storage, media synchronization, and operating system support have been extensively researched in other papers (for example, [12,14,15]), and will not be addressed here. Allocation efficiency is measured by the effective bandwidth per stream, or equivalently, by the maximum number of connections that can be simultaneously transported using a fixed total bandwidth.…”

We present efficient schemes for scheduling the delivery of variable-bit-rate MPEG-compressed video with stringent quality-of-service (QoS) requirements. Video scheduling is being used to improve bandwidth allocation at a video server that uses statistical multiplexing to aggregate video streams prior to transporting them over a network. A video stream is modeled using a traffic envelope that provides a deterministic time-varying bound on the bit rate. Because of the periodicity in which frame types in an MPEG stream are typically generated, a simple traffic envelope can be constructed using only five parameters. Using the traffic-envelope model, we show that video sources can be statistically multiplexed with an effective bandwidth that is often less than the source peak rate. Bandwidth gain is achieved without sacrificing the stringency of the requested QoS. The effective bandwidth depends on the arrangement of the multiplexed streams, which is a measure of the lag between the GOP periods of various streams. For homogeneous streams, we give an optimal scheduling scheme for video sources at a video-on-demand server that results in the minimum effective bandwidth. For heterogeneous sources, a sub-optimal scheduling scheme is given, which achieves acceptable bandwidth gain. Numerical examples based on traces of MPEG-coded movies are used to demonstrate the effectiveness of our schemes.

Engineering tests and scientific experiments use a variety of techniques to simultaneously record phenomena that frequently are not well correlated to the human's visual and cognitive timeframe. Therefore, the captured data are subsequently analysed in a different timeframe using, for example, slow motion or time lapse, and in some cases the playback rate is variable in a more complex manner. We term this condition time elasticity. We present methods to achieve synchronism amongst the range of media streams captured whilst consuming a low overhead of computing resource. These schemes allow for variable start times and extents for individual media streams as well as providing for variable time increments both within one medium and across a range of media elements. The techniques have been demonstrated within a system for the analysis of vehicle crash tests.
