摘要： A network digital video recording (nDVR) system may take into account the capabilities of a requesting user's local DVR when managing network recordings. The user's local DVR may include a temporary buffer that is normally used to record what the DVR is tuned to, and may be used for local trickplay functionality such as pausing live television. The nDVR features described herein may track the usage of the user's temporary DVR buffer, and use that in determining what to stream in response to a user's playback request. The nDVR system can also determine if the user's local DVR has an unused tuner at a time of a program recording, and can instruct the user's local DVR to also tune to the program.

摘要： An archive model can be used for managing networked storage of recorded content, such as network DVR (digital video recorder) content. Content may be initially recorded to an active storage device, with individual duplicate copies recorded for each requesting user, and subsequently archived to an archive storage device. For playback, the content can be reconstituted into the active storage device prior to delivery to the requesting user. Content can be predictively reconstituted in anticipation of user needs, and the reconstitution capacity of the system can be dynamically reallocated for load balancing.

摘要： Tokens and policy descriptors are used for dynamic on demand session management in a distributed and scalable architecture for on demand sessions and resource management. The architecture includes an on demand client, a purchase server, and a session manager. A purchase token is generated at the purchase server and assigned to the on demand client. The purchase token represents at least one requested asset. In response to an on demand session set-up request corresponding to the purchase token from the on demand client to the session manager, the purchase token is expanded to generate at least one dynamic policy management descriptor for the on demand session. This provides token-based purchase authorization and policy management for on demand services.

摘要： A secondary packetized data stream, such as a commercial, is spliced with a primary packetized data stream, such as a network television program. The system does not require decompression of the data in the primary data stream, and is particularly suitable for use at a cable system headend to allow the insertion of commercials from local businesses into a nationally broadcast television program. When a start signal is received, a pre-splicing packet of the primary stream is determined. The pre-splicing packet is the packet closest to the start time which carries an anchor frame (e.g., I or P frame) start code. To prevent a potential discontinuity at the decoder, the pre-splicing packet is processed to discard the anchor frame data, and to insert a number of stuffing bytes which is equal to the number of bytes discarded into an adaptation field of the pre-splicing packet. To further maintain continuity at the decoder, identifying data of the primary stream such as PID and PSI data, is retrieved and provided to the secondary stream. A number of null packets are inserted into the output stream at the transition point between the main program and the commercial to prevent a buffer overflow at a decoder which receives the output stream.
