Information processing device and method for processing signal of information processing device
View Patent ↗An information processing device is provided with plural HDMI connectors through which an audio signal is supplied to the other information processing device. The device allows selection of an audio signal supply destination. The audio signal supply is requested, and the audio signal is supplied to the specified information processing device in the requested arriving order. The information processing device of a specific type is determined as a priority device which is preferentially selected to receive the audio signal. If the information processing device of specific type is determined as the priority device, and supply of the audio signal therefrom is requested, the audio signal is supplied to the priority device by terminating the audio signal supply to the other information processing device. The audio signal may be supplied to plural supply destinations.
1. An information processing device for processing an input information signal which contains an audio signal, comprising:
Plural High Definition Multimedia Interface (HDMI) connectors for transmission and reception of the information signal with an external information processing device;
an audio separation unit for separating the audio signal from the information signal supplied from the HDMI connectors;
an output connector selection unit which selects at least one of the plural HDMI connectors so as to supply the audio signal separated by the audio separation unit to the selected HDMI connector, or does not supply the audio signal to any one of the HDMI connectors; and
a control unit for controlling an entire operation of the information processing device, wherein the control unit controls the output connector selection unit to output the separated audio signal to the external information processing device from one of the plural HDMI connectors based on a predetermined condition;
wherein:
the predetermined condition is an issue order of a command of the information processing device to the external information processing device to output the audio signal to a specified external information processing device of external information processing devices, or a command of the specified external information processing device to the information processing device to output the audio signal to the specified external information processing device; and
the control unit controls the output connector control unit to output the separated audio signal to the specified external information processing device from the HDMI connector, to which the specified external information processing device has been connected based on the command in the command issue order.
2. The information processing device according to claim 1 , further comprising an On Screen Display (OSD) circuit for superimposing an OSD display which notifies a user of output of the separated audio signal to the external information processing device on the separated video signal.
3. An information processing device for processing an input information signal which contains a video signal and an audio signal, comprising:
Plural High Definition Multimedia Interface (HDMI) connectors for transmission and reception of the information signal with an external information processing device;
a first video audio separation unit for separating a first video signal and a first audio signal accompanied with the first video signal, from the information signal supplied from the HDMI connectors;
a broadcast receiver unit for receiving a broadcast signal of a television broadcast;
a second video audio separation unit for separating a second video signal and a second audio signal accompanied with the second video signal, from the broadcast signal received by the broadcast receiver unit;
an input switching unit for selecting one of the supplied first video signal separated by the first video audio separation unit and the supplied second video signal separated by the second video audio separation unit, and selecting one of the first audio signal separated by the first video audio separation unit and the second audio signal separated by the second video audio separation unit in synchronization with the video signal;
a display unit for receiving the video signal selected by the input switching unit to display the video information contained in the video signal;
a speaker for receiving the audio signal selected by the input switching unit to generate audio information contained in the audio signal;
an output connector selection unit which receives the audio signal selected by the input switching unit to supply the audio signal to at least one of the plural HDMI connectors by selection or does not supply the audio signal to any one of the HDMI connectors;
a control unit for controlling an entire operation of the information processing device, wherein the control unit controls the output connector selection unit to output the separated audio signal from one of the plural HDMI connectors to the external
information processing device based on a predetermined condition; and wherein:
the predetermined condition is an issue order of a command of the information processing device to the external information processing device to output the audio signal to a specified external information processing device of external information processing devices, or a command of the specified external information processing device to the information processing device to output the audio signal to the specified external information processing device; and
the control unit controls the output connector control unit to output the separated audio signal to the specified external information processing device from the HDMI connector, to which the specified external information processing device has been connected based on the command in the command issue order.
4. The information processing device according to claim 3 , further comprising an On Screen Display (OSD) circuit for performing an OSD display which notifies a user of output of the separated audio signal to the external information processing device on the display unit.
