Abstract:
1. A system for determining an encoding rate for an MPEG based digital video information stream comprising: a service quality manager server comprising a processor configured to determine an encoding rate of a digital video information stream for a customer comprising a viewer of a cable system, said processor configured to: receive a video quality service parameter from a service profile of said customer wherein said video quality service parameter indicates a level of video quality to be streamed to said customer, determine whether said customer is presently being provided with another digital video information stream in response to a previous video on-demand request, and if so, determining an associated encoding level of said another digital video information stream, determining a level of resource allocation related to bandwidth on a shared transmission medium serving said customer, determining one from a plurality of encoding rates for said viewer in response to a present request for video on-demand service, reducing the quality of video encoding presently used for said another digital video information stream being provided to said customer in response to the present request for a video on-demand service when it is determined that said customer is presently being provided with said another digital video information stream; providing authorization for a VOD Server comprising a VOD Session manager to provide said digital video information stream, wherein said digital video information stream is encoded at said encoding rate, and updating said level of resource allocation commensurate with said encoding rate used to encode said MPEG based digital video information stream and by taking into account the reduction of quality of said another digital video information stream.
