    摘要： The stress-induced birefringent single mode optical fiber includes an optical core having a high refractive index and a high thermal expansion coefficient. An arrangement formed from an optical material having a low refractive index and a low thermal expansion coefficient is disposed to engage the outer surface of the core tangentially at opposite ends of a diameter of the core to establish a stress therein. Air encompasses the remainder of the outer surface of the core to provide a light guiding cladding for the core and, hence, the fiber itself. The arrangement to establish the stress may include a pair of flat plates engaging the outer surface of the core tangentially which are entrapped in a circular tube which is concentric with the core such that air is entrapped between the plates and the circular tube to provide the light guiding cladding. Alternatively, an elliptical tube is provided to engage the outer surface of the core at the minor axis of the elliptical tube to provide the desired stress in the fiber. In this case air is enclosed in the elliptical tube to provide the light guiding cladding.

    摘要： A system is provided in which an interactive television program guide is implemented on user television equipment such as a set-top box. The program guide provides an operator showcase in the form of one or more operator showcase television listings screens, each of which contains a set of television listings information. The sets of television listings information are generated by querying a database of television listings data in a database in the set-top box. Each database query is based on content criteria previously selected by the cable system operator or other service provider. The service provider is also able to define the format with which the television listings information is displayed in the television listings screens. A title and logos may also be selected by the service provider for each screen. The operator showcase television listings screens may therefore by customized and branded by the service provider. The user may access multiple operator showcase television listings screens using a centralized operator showcase menu.

    摘要： A system is provided that allows a user to select a pay program for purchase from a program guide. The program guide determines whether the selected program is part of a package of pay programs. If the selected program is part of a package, information regarding the package is provided to the user so that the user may decide whether to purchase the package. If the selected program is part of several packages, information for all packages is provided. The system automatically sets reminders for packages containing repetitive programming. The system monitors whether the user has watched any of the programs in such packages. When the user watches a program from the package, the remaining reminders are cancelled. If a user does not watch any programs in a package of any type, purchase of the package is cancelled and the user is provided with the opportunity to reschedule.

    摘要： A client-server interactive television program guide system is provided. An interactive television program guide client is implemented on user television equipment. The interactive television program guide provides users with an opportunity to define expressions that are processed by the program guide server. The program guide server may provide program guide data, schedules reminders, schedules program recordings, and parentally locks programs based on the expressions. Users' viewing histories may be tracked. The program guide server may analyze the viewing histories and generates viewing recommendations, targets advertising, and collects program ratings information based on the viewing histories.
