  • Patent number: 6137546
    Abstract: An autoprogrammer is provided for a television receiver capable of receiving conventional analog (NTSC) channels and DTV (8VSB) channels. First, conventional analog channels are identified and then skip channel data for each of the channels is stored in a memory. Subsequent executions of the autoprogramm function map DTV channels. Skip channel data is entered in the memory for these additional DTV channels. Mapping DTV channels occurs without deletion or overwrite of previous channel mapping information. Additionally information is stored in the skip channel memory giving antenna location for mapped DTV stations. DTV autoprogramming can be carried out at different channel positions.

  • Patent number: 6111677
    Abstract: The present invention is a method and apparatus for controlling a device by a remote controller. A receiving unit receives a first signal emitted by the remote controller and converts the received signal into a data stream. A communication medium carries the data stream from the receiving unit. A transmitting unit receives the data stream from the communication medium and converts the received data stream into a second signal compatible with the device.

  • Patent number: 6075570
    Abstract: It is an object of the present invention to provide an electronic program guide system and an electronic program guide displaying method that allow a desired program to be selected in a short time and at a high degree of reliability. EPG data of programs received by an IRD 4 through a satellite and EPG data of programs transmitted as a ground wave and received by a TV receiver 5 are converted into EPG data with an integrated format by an EPG receiver 6. The integrated EPG data is then output and displayed to the TV receiver 5.

  • Patent number: 6011526
    Abstract: The invention provides a display apparatus which operates in a synchronized relationship with a movement of the body of a viewer. A movement amount or a turning angle of the entire body or a part of the body of a viewer such as, for example, a movement of the eye-balls or a turning angle of the head, is detected by a sensor, and a portion of an original image is extracted and displayed in response to a magnitude of the detected movement amount or turning angle. Simultaneously, an audio signal is processed based on the information from the sensor so that an audio image may be formed at a normal position corresponding to the displayed image.

  • Patent number: 5978039
    Abstract: In a television equipped with an image control apparatus, when a signal reception condition is deteriorated, a poor image is not displayed on the television screen by reproducing saved image data. The image control apparatus is arranged by a receiver for receiving a signal including image data, a detecting device for detecting disturbance of the; signal received by the receiver, a memory for saving the image data included in the signal received by the receiver, and a display controller for controlling display of the image data on a display unit. That image data saved in the memory is read out on the detecting device detecting the disturbance of the signal and is displayed, while the disturbance of the signal is continued.

  • Patent number: 5652628
    Abstract: A television signal receiving apparatus which receives, analyzes and displays an information signal which is multiplexed onto a broadcasting wave and transmitted, and through the resulting information which has been obtained by analysis of the continuously stored information signal can display the information in such a way as to be related to the image information which corresponds to an associated one of a number of broadcasting channels. In this way a television signal receiving apparatus which is convenient for a user can be realized.

  • Patent number: 5512955
    Abstract: A method for entering channel representative information provided by a broadcasting signal that has been received by a television signal receiving apparatus and setting a plurality of channels in response thereto is disclosed. The method includes a first step for initiating channel setting by a CPU contained in a television signal receiving apparatus in response to an initiating signal; a second step for setting a start channel number in a counter; a third step for selecting a channel from the broadcast signal in accordance with the channel number in the counter; a fourth step for judging whether the selected channel is an active channel; a fifth step for extracting an information signal from the selected channel if the selected channel has been judged active in the prior step; and a sixth step for writing information represented by the information signal and the channel number of the selected channel to a memory.

  • Patent number: 5477275
    Abstract: A video signal receiving system having a plurality of video signal receiving apparatuses wherein use of a remote commander for one of the plurality of video signal receiving apparatuses allows a user to remotely control others of the plurality of video signal receiving apparatuses. Additionally, if such remote control is not direct control but composite control that requires control by a microcomputer, use of the above-mentioned remote commander allows the user to perform the composite control over the above-mentioned other video signal receiving apparatuses without adding necessary composite control capabilities to the other video signal receiving apparatuses.
