Abstract: A system and method for providing program guide information to subscribers is disclosed. In one embodiment, the method is applied to a broadcasting system having a plurality of service networks, each broadcasting a set of programs and program guide information describing at least a portion of the set of programs. The method comprises the steps of determining a receiver station configuration; receiving a first program guide information at the receiver station, the first program guide information comprising a default transmitting network identifier value uniquely identifying the service network transmitting the first program guide information; and generating a first program guide from the first program guide information and presenting the first program guide, according to a comparison between the determined receiving station configuration and the default transmitting network identifier.

Abstract: In a value dispensing system, a system and method for securely loading and executing software in a secure device that does not include any non-volatile programmable memory is provided. A non-secure portion of the value dispensing system stores software for loading into the secure portion when needed. Commands being sent to the secure printer are monitored to determine if the secure has the necessary software to execute the command. If the secure device currently does not have the necessary software to execute the command, the command is delayed and the proper software is loaded from the non-secure portion to the RAM of the secure device. A signature associated with the software is verified to ensure the authenticity of the software. If the signature is verified, the command is passed to the secure device, and, utilizing the software in the RAM, the command is executed by the secure device.

Abstract: Electronic television program guide information is downloaded, stored and searched by a local device. A plurality of linked lists are used to remove redundancy, increase search speed, and allow dynamic categories. When a new category is encountered a new head node for a link list data structure is created. When a first program guide object containing information related to that category is downloaded, a link is made (i.e., a pointer is stored) from the head node to the guide object. When subsequent program guide objects containing information related to that category are downloaded, links are added to the end of the list or inserted in alphabetical order. As guide objects expire the links are removed. When no links remain in a particular category the head node for that category is deleted.

Abstract: A method and apparatus for providing a virtual video on demand services is disclosed. The method and apparatus disclose the storing of a segment of the video program in advance for VOD viewing at a later time. When the subscriber selects VOD service, a pre-stored video segment is retrieved for presentation to the subscriber. Remaining video program segments simultaneously broadcast on a plurality of channels are recorded in parallel while the pre-stored video program segment is retrieved and presented to the user.

Abstract: A method and apparatus for performing satellite selection in a broadcast communication system is provided. In some embodiments, a controlling data stream broadcast on a first satellite over a broadcast channel is utilized to indicate that information signals such as a television program are being carried on the same channel on a different satellite. Remote receiving apparatus utilize the controlling data stream to locate the information signals by switching to the satellite identified in the controlling data stream.

Abstract: In a broadcast system such as a direct-to-home satellite system, program guide information for different time periods is transmitted on different carousels (e.g., one for 0-6 hours from current time, one for 6-24 hours, one for 24-72 hours, etc.) and broadcast on all transponders. Guide information for time periods in the near future is transmitted more frequently (i.e., less information per carousel) than guide information for later time periods. The receiving IRD sets a bit mask to indicate which carousel or carousels it requires and downloads them in serial or parallel. Updated information is never missed because it is given a bit pattern that is never screened by the mask. Further, the IRD can download the program guide information in the background (i.e., while displaying video) because it does not need to tune to a different transponder.

Abstract: In a data communication system such as a high capacity DBS system, dynamic mapping of broadcast resources is provided to exploit occasional redundancy in the program content of two or more input data streams, freeing at least one broadcast resource to carry alternate bitstreams, such as additional programs or existing programs at higher quality. Transmission maps defining the correspondence between input data streams and broadcast resources, and reception maps defining the correspondence between broadcast resources and output data streams, are updated as needed to dynamically modify broadcast resource mapping to increase effective utilization of available bandwidth. Beneficial n:n-y:m mapping in a high capacity consumer DBS entertainment system is provided. Apparatus and methods for efficiently generating, maintaining and updating allocation maps with reduced overhead requirements, are disclosed.

Abstract: A method of broadcasting controlling data streams and remote receiving apparatus for using the same are disclosed. A viewer-channel-to-broadcast channel (VCBC) map is employed to map one or more controlling data streams to one or more channels. The VCBC map is stored in memory. When a user tunes to a channel, the VCBC map is checked to determine if a controlling data stream is associated with the tuned channel. The VCBC map is periodically updated and broadcasted.
