Description

  The present invention relates to a television receiver (television) and a video game system, and in particular, based on game model information and game scene mode information transmitted via a CEC line of an HDMI (High Definition Multimedia Interface) cable. The present invention relates to a television receiver (television) and a video game system capable of executing a game with image quality and sound quality suitable for the above scene.

  In a conventional video game system, an identification signal indicating that the video signal is output from the game machine is added to the video signal output from the game machine, and the identification signal added to the video signal output from the game machine is determined. Japanese Patent Application Laid-Open No. 2004-228561 adjusts the image quality of the video output on the screen of the television device according to the determination result and automatically adjusts the image quality of the video game so that the image quality does not become excessive brightness or contrast. Is disclosed.

  In addition, in a conventional television device, an input terminal for connecting to a game machine and a game machine selection switch are provided, and the video / audio signal cable of the game machine is connected to the input terminal, and the game machine selection switch is operated. Japanese Patent Application Laid-Open No. 2004-228867 discloses a technique that simplifies operations during a game by switching characteristics of the screen mode, image quality, sound quality, sound field, and the like to the game mode as the television apparatus is switched to the game mode.

Further, Patent Document 3 discloses a conventional image forming apparatus in which optimum image quality setting is performed according to the type of input image signal to be displayed.
JP 7-204350 A JP-A-8-23479 JP 2000-242212 A

  Since the technique described in Patent Document 1 is a unique format in which an identification signal of a game machine is superimposed on a video signal, each game machine must support the unique format, and is compatible with all game machines as standard. There are issues that cannot be done.

  Moreover, the technique described in Patent Document 2 must prepare an input terminal and a game machine selection switch corresponding to the game machine. In addition, since various game machine models cannot be determined dynamically, it is not possible to display with image quality and sound quality suitable for any game.
