摘要： A method is provided by which a subscriber accesses an SDV channel using a set top terminal. The method begins when the set top terminal receives a user request to tune to a first SDV channel. An active services list is also received over an access network. The active services list includes an entry for each currently available SDV program and a time-to-live (TTL) associated therewith. Tuning information is identified for the first SDV channel from its entry in the active services list. The set top terminal tunes to the first SDV channel using the identified tuning information. The channel change information associated with the user request is locally stored in set top terminal for transmission over the access network at a later time.

摘要： A switched digital video (SDV) system is provided that includes an SDV manager for coordinating SDV sessions requested by subscriber terminals associated with a service group. An input is provided for receiving content to be broadcast during the SDV sessions. At least one edge device is provided for receiving transport streams that include SDV programming provided by the input and for transmitting each transport stream over an access network to at least one of the subscriber terminals on one of a plurality of SDV channels. The SDV manager is configured to (i) monitor bandwidth used by the edge device to provide the SDV programming to the service group and (ii) cause a bit rate of at least one SDV program supplied to the edge device to be adjusted based on the monitored bandwidth usage.

摘要： A video on demand (VOD) asset management system (100). Content is moved within the VOD system in accordance with predetermined variables such that certain content, such as that which is in high demand, is located on a server (120, 125) which is nearer to a subscriber (130), and content which is in lesser demand is located on a server (110, 115) which is more remote from the subscriber. Content may also be duplicated or moved within the system based upon other variables such as demographics of the subscriber, whether there is an advertising campaign for the content, and the age of the content.

摘要： A method is provided for acquiring channel viewership information in a content delivery system. The method begins by receiving a plurality of messages over an access network each indicating that a subscriber is switching to a specified broadcast channel. The information obtained from the messages is aggregated to generate channel viewership information identifying a number of subscribers tuned to each broadcast channel over a period of time. The channel viewership information is presented in a selected format.
