Abstract: A method of data management for efficiently storing and retrieving data in response to user access requests. The method includes receiving a request from at least one client for a title not resident in a storage server, where the title includes a play track having a plurality of chapters. The retrieval from a secondary storage device of play track portions proximate chapter delineation points is initiated, and bandwidth capacity and quality-of-service (QoS) parameters associated with the secondary storage device is determined. In the case of a client request to begin presentation of the title at one of the chapters, streaming of retrieved portions of the play track chapter to the client is initiated, masking latency associated with the secondary storage device is provided, and retrieval of at least unretrieved portions of the play track chapter and subsequent play track portions from the secondary storage device is initiated.

Abstract: A terminal for decoding and presenting encoded realtime and non-realtime interactive program guide (IPG) content including a realtime video portion and a non-realtime guide graphics portion. The terminal includes a demodulator operative to receive and demodulate a modulated signal to provide a transport stream, and a transport demultiplexer coupled to the demodulator and operative to receive and process the transport stream to provide a sequence of transport packets re-timestamped to synchronize encoded realtime content and encoded non-realtime content included therein. At least one video decoder is coupled to the transport demultiplexer and operative to receive and decode the encoded realtime and non-realtime contents to recover the realtime and non-realtime contents for the user interface.

Abstract: A method and apparatus for streaming content to an access network in an interactive information distribution system. The method encapsulates the content in accordance to an Internet Protocol (IP). The content is then transcoded into a format supported by the access network, and streamed over a distribution network to a remote server or to a subscriber terminal that is coupled to the access network. The apparatus is embodied as stream caching server for streaming the content encapsulated within the packet to access networks via a stream distribution network in response to a request for content. A packet processor is coupled to the stream server for processing the encapsulated content within the IP packets into a format native to the access network.

Abstract: Methods, systems, computer-readable media, and apparatuses for searching and delivering program content are described herein. A search request may be received from a first user device. One or more content sources in a distributed digital communication network may be searched for program content that satisfies the search criteria. Responsive to determining that the search was unsuccessful, the one or more content sources may be monitored for changes to determine whether at least one change satisfies the search criteria. Data indicative of the at least one matching result may be delivered to a second user device. A selection of a program content item associated with one of the at least one matching result may be received. According to one or more aspects, the selected program content item may be delivered to the second user device.

Abstract: A method and an apparatus are used to target interactive virtual objects to subscribers in a television delivery system. Programs are selected and virtual object locations are defined in the selected programs. The virtual objects available for targeting are categorized and the categories are correlated to subscriber information to determine the optimum targeting of the virtual objects. The virtual objects may be targeted based on individual subscriber information or on information related to groups of subscribers. When a frame of a program includes a virtual object location, a default or an alternate virtual object is displayed. The virtual object location may change over space or time. The virtual object may be interactive, and may be used to link a subscriber to a remote location, such as an Internet web site. An operations center or a cable headend may generate a group assignment plan that assigns the subscribers' television terminals to groups, based on factors such as area of dominant influence and household income. A retrieval plan is then generated that instructs the television terminals to select the desired virtual object for display. The television terminals record which virtual objects were displayed, and report this information to the cable headends and the operations center. The reported information is used to generate billing for commercial advertisers, and to analyze viewer watching habits. Interactive virtual objects are received by the television terminal with directions on actions to be taken upon selection of the interactive virtual object. Actions may result in the initiation of processes locally at the television terminal, or communication with a remote site for the initiation of processes to be performed remotely. The invention uses upstream data reception hardware, databases and processing hardware and software, and corresponding features in the televisions to accomplish these functions.

Abstract: An interactive information distribution system for providing secure distribution of video-on-demand content. The interactive information distribution system includes at least one programming source for storing at least one partially encrypted video program, and a distribution center including a remote server. The remote server stores the at least one partially encrypted video program received from the at least one programming source. The remote server also processes the partially encrypted video program corresponding to a subscriber requested video program to produce a fully encrypted video program. A subscriber-side distribution network, coupled to the distribution center, causes transmission of the fully encrypted video program to the requesting subscriber.
