Abstract: An access system and method for providing interactive access to an information source through a television distribution system is disclosed. The distribution system includes a television distribution network, headend distribution equipment at the headend of the distribution network, and a plurality of terminals at terminal ends of the distribution network. An input device and an upstream transmitter are associated with one of the terminals to input a command for the information source and to transmit the inputted command on an upstream channel of the distribution network, respectively. A headend server, upstream receiver, and data encoder are associated with the headend distribution equipment. The headend server is interfaced to the information source. The upstream receiver is interfaced to the headend server to receive and forward the command to the headend server.

Abstract: A system and method for accessing Internet-based and other information through a user television in a television distribution network enables a user to access and view information which is related to the programming content of a currently viewed television broadcast. This concept, known as channel hyperlinking, enables a television viewer to download Internet Web pages, and the like, which are related to a currently viewed advertisement, program, newscast, etc. To facilitate channel hyperlinking, each user of the system sends channel hyperlink requests through an upstream channel to a network headend by actuating a hyperlink button on a television remote control, for example. The network headend is interfaced to the Internet by means of an Internet Service Provider (ISP), and downloads HTML Web page data from the Internet to the requesting user.

Abstract: A system and method for transmitting programming guide and other information in a television distribution system permits selective access to the information. The information is formatted at a server (20) located in a network headend (12) into pages of text information, such as program listings for groups of channels at selected times of day, and preferably is broadcast continually on one or more designated channels (18) to a plurality of viewer set tops (16). Each of the set tops (16) contains a terminal processor (29) which facilitates selection and display of the downloaded information by means of a script program or application. The server (20) preferably feeds the formatted pages of text in a repeating carousel manner to a multiplexer (27) that transmits the pages on one or more digital channels to the set tops (16). Preferably, a background screen on which the program listing information is to be overlayed is separately transmitted or is stored in the set tops (16).

Abstract: A national level information service system collects local and national interest information and advertisements from a plurality of remote providers that may be located around the country or the world, and distributes this information to one or more television distribution systems for viewing by the system viewers. The system provides timely information relating to various areas of interest, including, for example, news, sports, weather, stock information and the like, that can be viewed on one or more television channels. Providers of the national and local interest information periodically collect the raw data containing the information to be broadcast, and store the data at a designated location, preferably on the provider's Internet server. These stored files are then periodically retrieved and compared to previously retrieved files to determine whether they have been updated by the information provider.

Abstract: A system and method for interactive broadcast of Internet web pages, or the like, on dedicated downstream channels in a cable television system or the like facilitates hyperlinking by a user from a broadcast television program to a web page, or between web pages, for example. In one embodiment, each user's set top is programmed with channel mapping information that maps each hyperlink request to a particular channel and time where the requested information is being broadcast in a multiplexed information stream. In response to receipt of a hyperlink request from a user actuating a remote control button, mouse or keyboard, the set top tunes to the appropriate one of the downstream channels, and downloads the web page or other information. In one embodiment to facilitate picture-in-picture capability using a single tuner, the tuner in the set top briefly tunes away from the video program to the appropriate data channel for receiving the hyperlink information.

Abstract: Navigation techniques enable Internet web pages and other image frames to be navigated using a conventional keyboard or a television remote control, for example. In a first technique, a guide mapping application links objects in the various frames contained in an accessed web page so that when a user actuates a directional button on a remote control or a keyboard, the guide mapping application navigates the user to an object in the present frame or in another frame to which a currently selected object is linked. The guide mapping application also employs “edge of frame” indicators in those objects which are located on an edge of a frame. When an “edge of frame” indicator is detected, the application searches for and locates the appropriate adjacent frame, as well as the object within the adjacent frame that is located in the closest proximity to the object containing the “edge of frame” indicator, and then navigates the user to that object.

Abstract: An access system and method provides interactive access to an information source, such as the Internet, through a networked distribution system, such as a television distribution system. Each user in the television distribution system can access the Internet through an associated terminal by sending commands through an upstream channel to a headend server which is interfaced between a television network headend and an Internet Service Provider(ISP). The headend server manages all Internet information requests from the terminals by forwarding the requests to the ISP and receiving the requested information therefrom. An Internet Protocol (IP) address is assigned only to the headend server which keeps track of the terminals requesting information by means of terminal identification numbers or codes associated with each request.

Abstract: Method for increasing the recording time of a digital video tape recorder ("VTR") and for supporting multiple normal play modes of digital VTR operation, e.g., a standard play mode of operation and one or more long play modes of operation. To achieve long play mode operation data reduction is performed on a received full rate video data stream to generate a reduced rate video data stream. Data reduction is performed using data prioritization and selection, requantization of full rate data stream, and/or by selecting data to be included in the reduced rate data stream as a function of what portion of a video frame the data represents. The reduced rate data stream is generated to be compliant with the data format of the full rate data stream. During long play mode recording operation the data in the reduced rate data stream is recorded on a tape at the same tape data density as used during standard mode VTR operation.
