Abstract
An output device to output an image and/or a sound based on a signal input from one of a plurality of external devices connected to the output device, the external devices including an HDMI source device to input an HDMI signal to the output device. The output device is configured to instruct an adjustment of sound volume of the sound output from the output device; to adjust the sound volume of the output sound in accordance with an instruction from an instruction section; to judge whether a header of an Audio InfoFrame exists in InfoFrame data in the HDMI signal input from the HDMI source device or not; and to invalidate the instruction from the instruction section during a period from time when the header of the Audio InfoFrame is judged not to exist by the judgment section to time when the header is judged to exist.
Claims5
An output device to output an image and/or a sound based on a signal input from one of a plurality of external devices connected to the output device, the external devices including a High-Definition Multimedia Interface (HDMI) source device to output an HDMI signal to the output device, the output device comprising:
- an instruction section to perform an instruction for adjusting sound volume of the sound to be output from the output device;
- an adjustment section to adjust the sound volume of the sound to be output in accordance with the instruction from the instruction section;
- a judgment section to judge whether a header of an Audio InfoFrame exists in InfoFrame data in the HDMI signal input from the HDMI source device or not;
- and
- an invalidation section to invalidate the instruction from the instruction section so that the previously set sound volume is maintained during a period from when the judgment section judges that the header of the Audio InfoFrame does not exist to when the judgment section judges that the header exists.
An output device to output an image and/or a sound based on a signal input from one of a plurality of external devices connected to the output device, the external devices including a High-Definition Multimedia Interface (HDMI) source device to output an HDMI signal to the output device, the output device comprising:
- an instruction section to perform an instruction for adjusting sound volume of the sound to be output from the output device;
- an adjustment section to adjust the sound volume of the sound to be output in accordance with the instruction from the instruction section;
- a judgment section to judge whether a header of an Audio InfoFrame exists in InfoFrame data in the HDMI signal input from the HDMI source device or not;
- a selection section to select one of the plurality of external devices;
- and
- an invalidation section to invalidate the instruction from the instruction section so that the previously set sound volume is maintained during a period from when the judgment section judges that the header of the Audio InfoFrame does not exist to when the HDMI source device becomes unselected by the selection section.
An output device to output an image and/or a sound based on a signal input from one of a plurality of external devices connected to the output device, the external devices including a High-Definition Multimedia Interface (HDMI) source device to output an HDMI signal to the output device, the output device comprising:
- an instruction section to perform an instruction for adjusting sound volume of the sound to be output from the output device;
- an adjustment section to adjust the sound volume of the sound to be output in accordance with the instruction from the instruction section;
- a selection section to select one of the plurality of external devices
- a judgment section to judge whether a header of an Audio InfoFrame exists in InfoFrame data in the HDMI signal input from the HDMI source device or not;
- an invalidation section to invalidate the instruction from the instruction section so that the previously set sound volume is maintained during either of a period from when the judgment section judges that the header of the Audio InfoFrame does not exist to when the judgment section judges that the header exists and a period from when the judgment section judges that the header of the Audio InfoFrame does not exist to when the HDMI source device becomes unselected by the selection section;
- and
- an informing section to inform a fact that the instruction has been invalidated when the instruction from the instruction section has been invalidated by the invalidation section.
