  • Publication number: 20040103439
    Abstract: A television system provides access to Internet data simultaneously with a displayed television program. Data units including data address sites available through a networked computer system such as the Internet are embedded in a television signal along with a television program. Information representing the data address site, such as an icon or descriptive text, is displayed simultaneously with the television program on the television. If the user selects the data address site, a data retrieval terminal in two-way communication with the network and associated with the television establishes a connection with the network and requests the data corresponding to the selected data address site. The retrieved information is then formatted for display.

  • Publication number: 20040073920
    Abstract: A television viewer uses a PIP format for display of program related information such as television program listings from a program schedule data base in the background and moving, real time or stored video clip images of a program selected from the displayed listings in the PIP window. All the text of the background information lies outside the PIP window. In one embodiment, as the viewer selects a particular program from the display of current television program listings by means of a cursor or a code number, the corresponding program automatically appears in the PIP window.

  • Publication number: 20040034866
    Abstract: A television system comprises an electronic program guide (EPG) including a picture-in-picture (PIP) window and means for returning to a last channel viewed full screen (LCF) in a television viewing mode prior to entering the guide mode. The EPG displays a program list including a listing for the LCF and text identifying it as such. This last channel listing is positioned at the top of a program list area in the guide. The viewer returns directly to the LCF in the television viewing mode by setting a cursor to the last channel listing prior to exiting the guide mode. In guides including listings for future programs, the last channel listing remains in a designated position of the program list area.

  • Patent number: 6687906
    Abstract: In one embodiment, the invention is a system and method for simultaneously displaying advertisements with an electronic program guide (EPG). The system displays television schedule information in rows of schedule information items including the time and channel for at least a portion of the displayed television schedule information items. An advertisement is selected for display from a plurality of advertisements, and the selected advertisement is displayed between two rows of the schedule information items simultaneously with the displayed television schedule information items.

  • Patent number: 6668133
    Abstract: Digital compressed codes, associated with advertisements enable a user to selectively record additional information, which would be broadcast on a television channel at a later time. The advertisement could be print advertisement or broadcast advertisement on television or radio. The user enters the digital code (I code) associated with an advertisement into a unit with a decoding means which automatically converts the code into CTL (channel, time and length). The unit within a twenty four hour period activates a VCR to record information on the television channel at the right time for the proper length of time. The decoded channel, time and length information can be communicated directly to a VCR and used by the VCR directly to automatically activate the VCR to record a given television information broadcast corresponding to the communicated channel, time and length.

  • Publication number: 20030213001
    Abstract: Multiple channel maps are embedded in a television transmission and the appropriate channel corresponding to the particular television service used by the viewer is downloaded for use with the television receiver. Each channel map is accompanied by a channel map identifier which identifies the source of the television transmission and a geographic identifier. The source of a television transmission is automatically detected by monitoring the radio-frequency spectrum allocations of telecast stations. The geographic area identifier is determined by comparison with a user inputted geographic area identifier. The channel map having a channel map identifier corresponding to the detected television transmission source and the user inputted geographic area identifier is downloaded and stored for future use.

  • Publication number: 20030074664
    Abstract: A system for providing an electronic program guide for both over the air channels and direct broadcast satellite channels includes a VCR (80) with an RF tuner. The RF signal carrying the over the air channels is connected to the RF input (64) of the DBS receiver (50), combined with an RF modulation on channel 3 (or 4) of the DBS channel tuned by the DBS receiver. The combined RF signal is sent to the RF tuner in the VCR, which tunes either channel 3 (or 4) for the DBS channel or the appropriate RF channel for a local over the air channel. The output of the RF tuner is output on the VCR's baseband video output (84) which is connected to a baseband video input (66) on the DBS receiver. This system provides a baseband video signal for both over the air and DBS channels.

  • Publication number: 20030063218
    Abstract: A local language is pre-stored in permanent memory. Equivalent data is transmitted in the vertical blanking interval (VBI) to television receivers. Each equivalent data set comprises a unique language identifier and a foreign language translation of, or graphical representative of, the local language pre-stored in permanent memory. The viewer selects the language to be displayed from an on screen menu with a remote controller. The selected equivalent data is retrieved from the VBI and stored in a RAM for future display. When the microprocessor calls up the text of a command for display, the equivalent data is substituted for the local language data so the foreign language version of the command can be displayed in a seamless manner. If no equivalent data is in the RAM, the local language pre-stored in permanent memory is displayed on the television screen in accordance with the normal operation of the microprocessor.

  • Patent number: 6526576
    Abstract: In A direct broadcast satellite (DBS) systems, local over the air channels are not included in the satellite signal or in the program guide provided by conventional direct broadcast satellite systems. Rather, over the air channels may be received from a television antenna or a cable television system. The disclosed system for providing an electronic program guide for both over the air channels and direct broadcast satellite channels includes a VCR (80) with an RP tuner. The RE signal carrying the over the air channels is connected to the RF input (64) of the DBS receiver (50), combined with all RF modulation on channel 3 (or 4) of the DBS channel tuned by the DBS receiver. The combined RF signal is sent to the RF tuner in the VCR, which tunes either channel 3 (or 4) for the DBS channel or the appropriate RF channel for a local over the air channel. The output of the RF tuner is output on the VCR's baseband video output (84) which is connected to a baseband video input (66) on the DBS receiver.

  • Publication number: 20020181936
    Abstract: A television system has a television viewing mode and a guide mode. The guide mode includes an electronic program guide (EPG), which provides the viewer program information for tuned programs, and a tape index guide (TIG), which provides information for programs recorded on a video cassette. In both guides, real time images of a program are displayed in a PIP window on the television screen and guide information is displayed in the background. In both guides, the viewer may switch between a currently telecast program or a recorded program. The viewer may access either guide from the television mode and vice versa. In the guide mode, the viewer may independently switch the guide information and the type of program, i.e., tuned or recorded, in the PIP window.
