The design of interactive Video-on-Demand (VOD) sys­ tems is highly complicated when scalable stream merging is used. Support of requests under the Near Video-on-Demand (NVOD), where not all requests are serviced immediately, introduces additional complications. We develop an over­ all solution for designing interactive NVOD systems when stream merging is(More)
The design of interactive Near Video-on-Demand (NVOD) systems is highly complicated when scalable stream merging is used. We propose an intelligent client-side cache management policy for these systems, allowing and exploiting cache discontinuity. This policy maximizes the percentage of interactive requests serviced from the client’s own cache without(More)
The required real-time and high-rate transfer of multimedia data limits the numbers of requests that can be concurrently serviced by video-on-demand (VOD) systems. Resource-sharing techniques can be used to address this scalability challenge, but they greatly complicate the efficient support for interactive operations. We develop an overall solution for(More)
