ABSTRACT:
A system for remotely controlling client recording and storage behavior schedules the recording, storing, and deleting of multimedia content on a client system storage device. The invention accepts as input a prioritized list of program viewing preferences which is compared with a database of program guide objects that indicate when programs of interest are actually broadcast. A schedule of time versus available storage space is generated that is optimal for the viewer's explicit or derived preferred content. The viewer may request that certain content be captured, which results in the highest possible priority for those content. The invention provides objects called a capture requests that are sent by the service to client systems. Capture requests reflect local storage management decisions about how the client system storage is partitioned. Capture requests also allow the service to determine content to be recorded by the client system in the same manner that a viewer requests that certain content are recorded but are more powerful than what a viewer can request. Recording requests for a capture request can preempt viewer requests or be entered at the same or lower priority as a viewer request. Capture requests can adjust all aspects of a recording request and affect the capture request itself. Client system operational functionality are also manipulated by the service using capture requests.
