Abstract
According to one embodiment, an electronic apparatus includes a receiver and a transmitter. The receiver receives a video signal from an external electronic apparatus through a cable conforming to a High-Definition Multimedia Interface (HDMI) standard. The receiver receives, from the external electronic apparatus through the cable, information for transferring a signal using a function of Audio Return Channel (ARC) or enhanced Audio Return Channel (eARC) of the HDMI standard. The transmitter transmits a position information signal or an audio signal to the external electronic apparatus through the cable, in accordance with the received information.
Claims12
An electronic apparatus comprising:
- a receiver configured to:
- receive a video signal from an external electronic apparatus through a cable conforming to a High-Definition Multimedia Interface (HDMI) standard;
- and
- receive, from the external electronic apparatus through the cable, information indicative of a type of a signal to be transferred using a function of Audio Return Channel (ARC) or enhanced Audio Return Channel (eARC) of the HDMI standard;
- and
- a transmitter configured to:
- transmit a signal, which is switched between a position information signal and an audio signal in accordance with the received information, to the external electronic apparatus through the cable using the function;
- when the received information indicates transfer of the position information signal, set a first mode as a transfer mode in which the function is used, and transmit the position information signal to the external electronic apparatus through the cable using the function;
- and
- when the received information indicates transfer of the audio signal, set a second mode as the transfer mode in which the function is used, and transmit the audio signal to the external electronic apparatus through the cable using the function.
An electronic apparatus comprising:
- a transmitter configured to:
- transmit a video signal to an external electronic apparatus through a cable conforming to a High-Definition Multimedia Interface (HDMI) standard;
- and
- transmit, to the external electronic apparatus through the cable, information indicative of a type of a signal to be transferred using a function of Audio Return Channel (ARC) or enhanced Audio Return Channel (eARC) of the HDMI standard;
- and
- a receiver configured to:
- receive a signal, which is switched between a position information signal and an audio signal in accordance with the information, from the external electronic apparatus through the cable using the function;
- when the information indicative of transfer of the position information signal is transmitted and a first mode is set as a transfer mode in which the function of the external electronic apparatus is used, receive the position information signal from the external electronic apparatus through the cable using the function;
- and
- when the information indicative of transfer of the audio signal is transmitted and a second mode is set as the transfer mode in which the function of the external electronic apparatus is used, receive the audio signal from the external electronic apparatus through the cable using the function.
A control method of controlling an electronic apparatus that receives a video signal from an external electronic apparatus through a cable conforming to a High-Definition Multimedia Interface (HDMI) standard, the control method comprising:
- receiving, from the external electronic apparatus through the cable, information indicative of a type of a signal to be transferred using a function of Audio Return Channel (ARC) or enhanced Audio Return Channel (eARC) function of the HDMI standard;
- and
- transmitting a signal, which is switched between a position information signal and an audio signal in accordance with the received information, to the external electronic apparatus through the cable using the function, wherein the transmitting includes:
- when the received information indicates transfer of the position information signal, setting a first mode as a transfer mode in which the function is used, and transmitting the position information signal to the external electronic apparatus through the cable using the function;
- and
- when the received information indicates transfer of the audio signal, setting a second mode as the transfer mode in which the function is used, and transmitting the audio signal to the external electronic apparatus through the cable using the function.
A control method of controlling an electronic apparatus that transmits a video signal to an external electronic apparatus through a cable conforming to a High-Definition Multimedia Interface (HDMI) standard, the control method comprising:
- transmitting, to the external electronic apparatus through the cable, information indicative of a type of a signal to be transferred using a function of Audio Return Channel (ARC) or enhanced Audio Return Channel (eARC) of the HDMI standard;
- and
- receiving a signal, which is switched between a position information signal and an audio signal in accordance with the information, from the external electronic apparatus through the cable using the function, wherein the receiving includes:
- when the information indicative of transfer of the position information signal is transmitted and a first mode is set as a transfer mode in which the function of the external electronic apparatus is used, receiving the position information signal from the external electronic apparatus through the cable using the function;
- and
- when the information indicative of transfer of the audio signal is transmitted and a second mode is set as the transfer mode in which the function of the external electronic apparatus is used, receiving the audio signal from the external electronic apparatus through the cable using the function.
