  • Patent number: 8446533
    Abstract: In an AV system in which a television apparatus and a recorder are individually connected to an AV amplifier through an HDMI, in the case where sound is output from the AV amplifier, if insertion of headphones into the television apparatus is detected, control information to switch the destination of the audio data is transmitted from the television apparatus to the AV amplifier. The AV amplifier switches the destination of the audio data that is input from the recorder from a speaker output section to the television apparatus in accordance with the control information. Thus, even if the headphones are inserted into the television apparatus while the AV amplifier is outputting sound reproduced by the recorder, the sound can be output from the headphones.

  • Patent number: 8340499
    Abstract: To select a recording device for recording a program in a digital television receiver to which a plurality of recorders (recording devices) are connected, control is performed to acquire image quality information about the program to be recorded and to compare the program image quality to be recorded with the recording image quality of a recording medium for each connected recording device. Based on the result of this comparison, a recorder is selected that can secondarily record the program onto a recording medium without compromising the program image quality.

  • Patent number: 7620910
    Abstract: To improve ease of operation with which a user selects an image when many images are simultaneously displayed on a screen, a frame, which divides many images into 12 areas, is superimposed and displayed on a screen displaying thumbnail exhibition thereon. For example, the press of a channel key allows selecting one of the areas and moving to the selected area a focus frame indicating a candidate image for selection, and then the presses of cursor keys allow moving the focus frame to a desired image to be selected. The number of areas can be changed and displayed according to the number of channel keys when a television remote control is used, or according to the number of numeric keys when a mobile telephone is used.

  • Publication number: 20090184887
    Abstract: A display apparatus includes a main display control unit to control display characteristic parameters of a main display and a sub-display control unit to control display characteristic parameters of a sub-display. A determination unit determines whether to highlight data according to contents of the data to be displayed on the sub-display. When it is determined that the data is highlighted, the sub-display control unit controls the display characteristic parameter of the sub-display in a manner not interlocking with the display characteristic parameter of the main display. On the other hand, when it is not determined that the data is highlighted, the sub-display control unit controls the display characteristic parameter of the sub-display in a manner interlocking with the display characteristic parameter of the main display.
