Abstract

An electronic device having a clock portion for counting time and having the time on the clock portion set based on time information acquired from outside has a notification portion that communicates information of the time counted by the clock portion to an external device via a physical line. Alternatively, an electronic device has a first clock portion counting time and an acquisition portion that acquires, from an external device having a second clock portion for counting time and having the time on the second clock portion set based on time information acquired from outside, information of the time counted by the second clock portion via a physical line, and the time on the first clock portion is set based on the information acquired by the acquisition portion.

Claims

1. An electronic device having a clock portion for counting time and having time on the clock portion set based on time information acquired from outside, the electronic device comprising:

a notification portion that communicates information of the time counted by the clock portion to an external device via a physical line.

2. The electronic device according to claim 1,

wherein the physical line is an HDMI-CEC line.

3. The electronic device according to claim 1,

wherein the notification portion communicates the information on at least one of the following occasions:

when the external device starts information playback operation;

when the external device displays a time information setting screen on a display portion;

when the external device shifts into a stand-by state; and

when the time on the clock portion is set.

4. The electronic device according to claim 1,

wherein the notification portion communicates the information when the clock portion counts a change in value of minutes.

5. An electronic device comprising:

a first clock portion counting time; and

an acquisition portion that acquires, from an external device having a second clock portion for counting time and having time on the second clock portion set based on time information acquired from outside, information of the time counted by the second clock portion via a physical line,

wherein time on the first clock portion is set based on the information acquired by the acquisition portion.

6. The electronic device according to claim 5,

wherein the physical line is an HDMI-CEC line.

7. The electronic device according to claim 5,

wherein the acquisition portion acquires the information on at least one of the following occasions:

when the device starts information playback operation;

when the device displays a time information setting screen on a display portion;

when the device shifts into a stand-by state; and

when the time on the second clock portion is set.

8. The electronic device according to claim 5,

wherein the acquisition portion acquires the information when the second clock portion counts a change in value of minutes.
