Abstract: A method and a system for selecting and ordering broadcast programs uses an electronic program guide that may be broadcast to subscribers or posted on an Internet web site. The system allows national broadcasters to provide one or more channels of pay-per-view or subscription programming and to establish a mechanism for billing subscribers who access the programs. Subscribers may access the Internet and send a program request to a web site. An authorization is then forwarded to a billing center and to a local broadcaster. The billing center debits the subscriber's account, or prepares a bill. The local broadcaster sends the authorization to the subscriber. The authorization includes a program code and a terminal identifier that permit the subscriber's television or set top terminal to decrypt and display the program.

Abstract: This invention is a method of allocating bandwidth for a television program delivery system. This method selects specific programs from a plurality of programs, allocates the selected programs to a segment of bandwidth, and continues to allocate the programs until all the programs are allocated or all of the available bandwidth is allocated. The programs may be selected based on a variety of different factors or combination of factors. The selected programs may also be prioritized so that higher priority programs are distributed before lower priority programs in case there is not enough bandwidth to transmit all of the programs. This invention allows a television program delivery system to prioritize a large number of television programs and distribute these programs based on their priority levels. The invention also permits a television program delivery system to dynamically allocate bandwidth over time or based on marketing information, such as consumer demand.

Abstract: A menu-driven television program access system and method provide a menu structure that allows subscribers to select and view television programming and other services. The menu structure lists programs by program category or by chronological order of broadcast. The subscriber scrolls the menus until a desired program identifier, such as a title and date/time of broadcast is found. The subscriber then operates a “go-button” on a remote control to select the desired program. In response to operation of the “go-button,” a set top terminal turns to a channel carrying the selected program.

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. Advertisements are displayed during commercial breaks in the television programs. Such advertisements may be broadcast on the same channel as the television program. In addition, feeder channels may carry alternate advertising that may be better suited for certain viewing audiences. The operations center or the cable headend generate a group assignment plan that assigns the television terminals to groups, based on factors such as area of dominant influence, household income and other demographic data, and programs watched data gathered by the television terminals. 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.
