Abstract

According to one embodiment, a reception-side electronic device outputs reception specification data for receiving a signal suitable for the reception-side electronic device to a transmission-side device which selectively sends signals of the same contents in a plurality of signal forms. The reception-side electronic device includes transmitting/receiving and signal-processing units, a memory, a system setting unit, and a display processing unit which judges whether the first receiving specification data or the second receiving specification data is to be adopted as a signal to be transmitted to the transmission-side device.

Claims

1. A reception-side electronic device to output reception specification data to a transmission-side device which selectively sends signals of the same contents in a plurality of signal forms, the reception-side electronic device comprising:

transmitting/receiving and signal-processing units which transmit the receiving specification data to the transmission-side device and which receive a signal sent in a predetermined standard from the transmission-side device to decode the signal into a video signal;

a memory;

a system setting unit which sets first receiving specification data to designate a signal form as a default as well as second receiving specification data to designate a desired signal form among the plurality of signal forms and which stores the data in the memory; and

a display processing unit which is used to judge whether the first receiving specification data or the second receiving specification data is to be adopted as a signal to be transmitted to the transmission-side device.

2. The electronic device according to claim 1, wherein the receiving specification data is extended display identification (EDID) data defined by a high definition multimedia interface (HDMI) standard.

3. The electronic device according to claim 1, wherein the receiving specification data is extended display identification (EDID) data defined by a high definition multimedia interface (HDMI) standard, and the first receiving specification data and the second receiving specification data are data which designates a high-definition (HD) signal and data which designates a standard (SD) signal, respectively.

4. A video display device to output reception specification data to a transmission-side device which selectively sends signals of the same contents in a plurality of signal forms, the video display device comprising:

transmitting/receiving and signal-processing units which transmit the receiving specification data to the transmission-side device and which receive a signal sent in a predetermined standard from the transmission-side device to decode the signal into a video signal;

a memory;

a system setting unit which stores, in the memory, first receiving specification data which designates a signal form as a default as well as second receiving specification data which designates a desired signal form among the plurality of signal forms;

a display processing unit which is used to judge whether the first receiving specification data or the second receiving specification data is to be adopted as a signal to be transmitted to the transmission-side device; and

a conversion unit which converts, into another signal form, the signal of the desired signal form corresponding to the second receiving specification data, when the second receiving specification data is adopted, and sends the signal.

5. The video display device according to claim 4, wherein the receiving specification data is EDID data defined by an HDMI standard, and the first receiving specification data and the second receiving specification data are data which designates a high-definition (HD) signal and data which designates a standard (SD) signal, respectively.

6. The video display device according to claim 4, wherein the receiving specification data is EDID data defined by an HDMI standard,

the first receiving specification data and the second receiving specification data are data which designates a high-definition (HD) signal and data which designates a standard (SD) signal, respectively, and

the display processing unit displays a reception setting item of the HD signal and a reception setting item of the SD signal, respectively.

7. The video display device according to claim 4, wherein the receiving specification data is EDID data defined by an HDMI standard,

the first receiving specification data and the second receiving specification data are data which designates a high-definition (HD) signal and data which designates a standard (SD) signal, respectively, and

the display processing unit displays a reception setting item of the HD signal, a reception setting item of the SD signal and a reception setting item of an original source, respectively.

8. The video display device according to claim 4, wherein the receiving specification data is EDID data defined by an HDMI standard,

the first receiving specification data and the second receiving specification data are data which designates a high-definition (HD) signal and data which designates a standard (SD) signal, respectively,

the display processing unit displays a reception setting item of the HD signal and a reception setting item of the SD signal, respectively, and

the conversion unit is an SD-HD up-converter which converts the SD signal into the HD signal.

9. A method of controlling a control unit of a device having:

transmitting/receiving and signal-processing units which transmit reception specification data to a transmission-side device to selectively send signals of the same contents in a plurality of signal forms and which receive a signal sent in a predetermined standard from the transmission-side device to decode the signal into a video signal;

a memory;

a display processing unit which outputs the video signal; and

the control unit which controls an operation of a conversion unit to convert the signal form, the control unit controlling method comprising;

storing, in the memory, first receiving specification data which designates a signal form as a default as well as second receiving specification data which designates a desired signal form among the plurality of signal forms;

performing such display as to judge whether the first receiving specification data or the second receiving specification data is to be adopted as a signal to be transmitted to the transmission-side device; and

converting, into another signal form, the signal of the desired signal form corresponding to the second receiving specification data, when the second receiving specification data is adopted, and sending the signal.

10. The method of controlling the video display device according to claim 9, wherein the receiving specification data is EDID data defined by an HDMI standard, and the first receiving specification data and the second receiving specification data are data which designates a high-definition (HD) signal and data which designates a standard (SD) signal, respectively,

the method comprising:

converting the standard (SD) signal into the high-definition (HD) signal, when the standard (SD) signal corresponding to the second receiving specification data is sent.
