Abstract: Interactive content preservation and customization technology is placed at the broadcast facility to ensure reliable transmission of the interactive content to a local subsystem. An interactive content code detector detects interactive content codes in the video stream at the broadcast facility. The interactive content code detector is placed in the transmission path before the video stream is transmitted to broadcast facility hardware that may strip out, destroy, corrupt or otherwise modify the interactive content and interactive content codes. Once an interactive content code detector detects a code, an interactive broadcast server determines what action to take, and instructs an data insertion unit accordingly. The interactive content codes or interactive content may be placed in a portion of the video that is guaranteed by the broadcast facility to be transmitted, for example, the closed caption region of the vertical blanking interval.

Abstract: An interactive voting application is broadcast to a broadcast receiver. The broadcast receiver executes the voting application, allowing a voter to cast one or more votes on an electronic ballot, and then transmits the votes to a server. In a preferred embodiment, the server stores the votes so that the voters cannot be associated with their votes.

Abstract: A system and method provide sophisticated analysis of program viewership by executing interactive applications that generate responses describing the viewers' behavior. A broadcast server maintains a database of interactive applications each preferably associated with a program that will be broadcast. The interactive applications preferably include monitoring interactive applications that are configured to selectively monitor viewership, interactive application usage, and reception terminal usage. When the program is broadcast, the monitoring interactive application is inserted into the broadcast feed and delivered to a broadcast receiver such as a television set-top box. The broadcast receiver includes a processor, memory, and other hardware necessary to execute the interactive application.

Abstract: A system and method allow for the periodic re-configuring of broadcast receivers to control their storage of responses to interactive applications during a polling period. A broadcast server maintains a database of interactive applications each preferably associated with a program that will be broadcast. When the program is broadcast, an interactive application is inserted into the broadcast feed and delivered to a broadcast receiver such as a television set-top box. The broadcast receiver includes a processor, memory, and other hardware necessary to execute the interactive application. When executed, the interactive application generates a response which is transmitted to a local data center at, for example, the cable head-end. Generated responses have specific types. To manage the number and capacity of the system to receive responses, priority values are assigned to responses of different types.
