Abstract: Methods and systems for storing and accessing video data are presented. A method of storing video data may include receiving a reservation request to reserve a program for a user. The method may also include determining whether a reservation window associated with the program has expired. The reservation window may be based at least partially on a previously received reservation request. The method may also include storing a reservation record associating the program with the user after determining that the reservation window has not expired.

Abstract: A service management system for a communications network which accepts requests for communications services from service order sources. The service management system includes an interface to the service order sources, a database, and an interface to network elements which provide the communications services. The service order sources may have differing order input formats which are converted by the system into a single internal format for processing and determining of provisioning information to be output to the network-elements. The service management system includes table-driven logic which is used to validate and process the requests to determine the provisioning information. Once the provisioning information is determined, it is queued to the appropriate network element, and an acknowledgment is sent to the originating service order source. The service management system also includes a interface to query the database and network elements to perform debugging and error correction.
