    Abstract: A novel network manager (214) that monitors and manages cable headend (208) components and set top terminals (220) in a television delivery system (200) is described. The invention coordinates the reception of programming and control signals at a headend (208), storing signals for intelligent selection and distribution. The invention uses a receiver (254), a work station (256), a program control information processing component (258), a network management CPU (260), databases (262), control software (264) and an instruction memory (266). The invention uses these components to manage headend (208) components, such as signal reception equipment (234), an authorization component (236), a file server (215), MPEG decoders (250), buffers (252) and modulators (238). The invention is particularly useful in processing upstream subscriber communications (246). The invention accommodates various system services, including near video on demand (NVOD), virtual video on demand (VVOD), video on demand (VOD), interactive program services, program suggestion features, advertisement targeting, standard and custom menus, and data spooling and text overlaying.

    Abstract: An aggregator, operating in a digital communications network, includes a request and results processing server, a search engine server coupled to the request and results processing server and a content acquisition server coupled to the request and results processing server. A request and results processing server receives a request for content, the search engine server searches for the content and the content acquisition program acquires content for delivery to the user. The request and results processing server includes a search request processor that receives infonuation related to a user's search request and provides the infonuation to a search results fonu builder that creates an electronic search request. The search request may be augmented by using a content suggestion engine to add additional search tenus and descriptions to the search request. The aggregator may also include a decoder that decodes program content and program metadata from remote sources for storage at the aggregator, and an encoder that encodes content metadata and programs for delivery to the user. The aggregator may also comprise one or more crawlers, such as a content crawler, to look for program content in one or more digital communications networks.

    Abstract: A novel multiple channel architecture is designed to allow targeted advertising directed to television terminals connected to an operations center or a cable headend. Program channels carry television programs. During commercial breaks in the television programs, advertisements, which are also broadcast on the program channel, are displayed. However, additional feeder channels carry alternate advertising that may be better suited for certain viewing audiences. The operations center or the cable headend generate group assignment rules that allow a set top terminal to assign itself to groups, based on information collected and maintained solely within the set top terminal. A switching plan is then generated that instructs the television terminals to remain with the program channel or to switch to one of the alternate feeder channels during the program breaks based on its group assignment. The television terminals record which channels were viewed during the program breaks, and use this information for future local targeting of advertising.

    Abstract: An electronic book selection and delivery system distributes text to subscribers. The system provides for on-demand and virtual on-demand and virtual on-demand delivery of electronic books. Specified electronic books may be broadcast to a set of subscribers. Alternatively, a first section of the specified electronic books may be broadcast. A second section of each of the electronic books is then available for later delivery, upon order by a subscriber. The second sections, as well as first sections, and true on-demand electronic books may be loaded into one or more queues. The queues may then be emptied based on a priority model. Electronic books in an on-demand queue may be given priority for delivery over electronic books in other queues.
