摘要： A switched digital video (SDV) system includes an SDV manager for coordinating a SDV session requested by a subscriber terminal and a storage medium on which resides content to be transmitted during the SDV session. The system also includes a plurality of edge devices for receiving a transport stream that includes content provided by the storage medium and transmitting the transport stream over an access network to the subscriber terminal on one of a plurality of SDV channels. The SDV manager is configured to cause different renditions of an SDV program to be provided by the edge devices to subscriber terminals associated with different target groups. The target groups each include a plurality of subscriber terminals that is less than a number of subscriber terminals serviced by a distinct edge device or devices.

摘要： A process is provided that may be employed by a set top terminal when a viewer is engaged in a SDV session and is required to switch from one edge device to another. The method begins when a set top terminal receives an SDV program forwarded over an access network by a first digital modulator. The SDV program is received on a first SDV channel associated with the first digital modulator. Next, a request is received to tune to a second SDV channel associated with a second digital modulator to thereby continue receiving the SDV program over the access network. The set top terminal detects an event indicating that a change from the first SDV channel to the second SDV channel will lessen disruption to a viewer of the SDV program. Finally, the set top terminal tunes to the second SDV channel.

摘要： Scheduled data is received and distributed in a system, such as a DSDD system. A schedule director receives a schedule representing inventory of data available from a data source and desired times for distributing the data. The schedule director coordinates with one or more resource managers that maintain information regarding resource utilization in the system. The schedule director negotiates with the resource managers to reserve resources in the system for receiving the scheduled data from the data source, storing the received data, and/or preparing the received data for delivery to a user. Resources are reserved based on the schedule and the resources determined to be available. The resources are reserved to perform at least one task, independent of other resources in the system.
