Abstract

A video signal receiving apparatus controls a video display portion to display an error message when a video signal is received in a nonconforming video format. A user checks an error message and selects Yes through an input portion. A control portion of a video signal receiving apparatus controls a hot plug detection signal transmitting portion to transmit a Low signal serving as a reset signal as a hot plug detection signal for a predetermined period of time. At this time, a control portion of a video signal transmitting apparatus receives the Low signal for the predetermined period of time to reset a video format or the like, requires EDID to transmit a video signal in an optimum video format, and retransmits the video signal in the optimum video format to the video signal receiving apparatus in accordance with the EDID.

Claims

1. A data receiving apparatus comprising:

a transmitting/receiving portion which transmits or receives data;

an output portion which performs data outputting of an audio signal or an image signal in accordance with reception of the data; and

a control portion which, when the received data has a format different from a format in which the data can be output from the output portion, controls the transmitting/receiving portion to transmit a reset signal.

2. A data receiving apparatus according to claim 1, wherein

the output portion includes at least one of an image display portion and a audio output portion.

3. A data receiving apparatus according to claim 1, wherein

the transmitting/receiving portion includes a reset signal transmitting portion which transmits a Low signal conforming to the HDMI (High Definition Multimedia Interface) as the reset signal.

4. A data receiving apparatus according to claim 1, wherein the transmitting/receiving portion includes a reset signal transmitting portion which transmits a Low signal as the reset signal and an EDID transmitting portion which transmits EDID (Extended Display Identification Data) serving as data in a format in which the data can be output from the output portion.

5. A data receiving apparatus according to claim 1, wherein

the control portion outputs a message for checking a change in format to the output portion when the data has a format different from a format in which the data can be output from the output portion.

6. A data receiving apparatus comprising:

a transmitting/receiving portion which transmits or receives data conforming to the HDMI standard;

an output portion which performs data outputting of an audio signal or an image signal in accordance with reception of the data; and

a control portion which, when the received data has a format different from a format in which the data can be output from the output portion, controls the transmitting/receiving portion to transmit a Low signal as a reset signal.

7. A data receiving apparatus according to claim 6, wherein

the output portion includes at least one of an image display portion and a audio output portion.

8. A data receiving apparatus according to claim 6, wherein

the transmitting/receiving portion includes a reset signal transmitting portion which transmits the Low signal as the reset signal and an EDID transmitting portion which transmits EDID (Extended Display Identification Data) serving as data in which the data can be output from the output portion.

9. A data receiving apparatus according to claim 6, wherein

the control portion outputs a message for checking a change in format to the output portion when the data has a format different from a format in which the data can be output from the output portion.

10. A data receiving apparatus comprising:

a transmitting/receiving portion which transmits or receives data;

an output portion which performs data outputting of an audio signal or an image signal in accordance with reception of the data; and

a control portion which, when the received data has a format different from a format in which the data can be output from the output portion, controls the transmitting/receiving portion to transmit a reset signal which makes data in a format in which the data can be output from the output portion transmitted.

11. A data receiving apparatus according to claim 10, wherein

the output portion includes at least one of an image display portion and a audio output portion.

12. A data receiving apparatus according to claim 10, wherein

the transmitting/receiving portion includes a reset signal transmitting portion which transmits a Low signal conforming to the HDMI (High Definition Multimedia Interface) as the reset signal.

13. A data receiving apparatus according to claim 10, wherein

the transmitting/receiving portion includes a reset signal transmitting portion which transmits a Low signal as the reset signal and an EDID transmitting portion which transmits EDID (Extended Display Identification Data) serving as data in a format in which the data can be output from the output portion.

14. A data receiving apparatus according to claim 10, wherein

the control portion outputs a message for checking a change in format to the output portion when the data has a format different from a format in which the data can be output from the output portion.
