As mentioned.

  In addition, since the distance from the access point is changed by carrying, the process of switching the antenna is also one of the predetermined processes. When the antenna is switched, the reception sensitivity may be displayed as a bar. Further, in the case of TV, since it is possible that the viewing user has been switched, the data of the electronic program guide (EPG) may be updated to prepare for user channel selection. In addition, the recording of the continuation of the program that has been viewed so far on the built-in hard disk and DVD (Digital Versatile Disc) is started, and the video and / or audio signal is processed depending on the reception status according to the processing to be followed and played back later. A process for turning on noise reduction, a process for alerting the user with a warning sound or vibration when an AV code or a power source is inserted, and the like are also examples of the predetermined process.

  On the other hand, when the user finishes carrying and detects it, the process of canceling the audio mute, the process of gradually returning the sound to the value before carrying, the sound volume gradually returning and the user's volume at the midway Volume value Processing to stop when there is an operation, processing to cancel screen mute, processing to gradually release screen mute so that it does not turn on even if the main unit is heavy and temporarily installed (lighten gradually), Processing to cancel the power saving mode, processing to make it possible to quickly adjust according to the installation location by starting the image quality adjustment of the menu, because it may be difficult to see with the previous settings when carrying from outside → inside, inside → outside, The process of returning the antenna, the process of turning on the power when the power was turned on before carrying, the process of returning to the noise reduction setting before carrying, the process of finely adjusting the channel There may be mentioned as one of the one or return processing of a given process.

  Here, when the stand is on the floor, it is recognized that it has been carried, or when the stand is on the floor and the handle is released, it is recognized that the carrying has been completed, or when the built-in vibration sensor stops vibrating. It may be recognized that carrying is finished.

  Furthermore, it is preferable that the user can set whether or not to execute the various settings described above by an operation such as a menu. For example, if the user has set mute for audio and video, when he / she wants to watch a TV while he / she is watching TV in one room, The video is muted. Also, when watching a TV outdoors in a bright room and trying to take it back to a dimly lit room, the image adjustment is extremely different, so that the image adjustment screen will be launched and adjusted when the handle is set apart. However, since such a setting may be an unnecessary function for a certain user, it is preferable that the setting can be turned ON / OFF using a menu.

  As described above, according to the present embodiment, when carrying all or part of the portable audio-visual device, it is possible to execute processing suitable for the carrying situation without bothering the user. For example, the reception state may be deteriorated when moving, and the annoying noise at that time can be reduced. In addition, when the user does not see the video when moving (except when viewing), the video can be muted to extend the battery time and save energy. Furthermore, the system configuration in which the television receiver 3 can be covered not only from the power cord 41 but also from the wireless center 4 as shown in FIG. 5 is expected to increase in the future. Therefore, by applying the present invention to such a configuration, it is possible to expect energy saving during carrying when viewing with a thin and light portable cordless TV or the like, and battery time can be extended.
