Abstract

A video output device includes an OSD generation means for generating OSD (On Screen Display) for controlling the device itself, a detection means for detecting a connected state in which the device is connected to a prescribed external display device in a state realizing a mutual device control function which can perform control between devices mutually and a forced output means for outputting the OSD generated by the OSD generation means to the external display device forcibly and displaying the OSD on a display portion of the external display device regardless of any setting of the device when detecting the connected state by the detection means.

Claims

1. A video output device comprising:

an OSD generation means for generating OSD (On Screen Display) for controlling the device itself;

a detection means for detecting a connected state in which the device is connected to a prescribed external display device in a state realizing a mutual device control function which can perform control between devices mutually; and

a forced output means for outputting the OSD generated by the OSD generation means to the external display device forcibly and displaying the OSD on a display portion of the external display device regardless of any setting of the device when detecting the connected state by the detection means.

2. The video output device according to claim 1,

wherein the forced output means outputs playback control buttons with respect to video stored in the video output device as the OSD.

3. The video output device according to claim 2,

wherein the forced output means stops outputting the OSD to the external display device in the case that, after some operation was performed with respect to the OSD, the next operation is not performed until a prescribed period of time has passed.

4. The video output device according to claim 3,

wherein the forced output means forcibly outputs the OSD again in the case that, after the output of the OSD was stopped, some operation has been performed with respect to the display portion of the external display device.

5. The video output device according to claim 4, further comprising:

an OSD output means for continuing displaying of the OSD to a monitor of the device itself regardless of whether the OSD is forcibly outputted to the external display device or not.

6. The video output device according to claim 1,

wherein the forced output means outputs the OSD in a state in which the OSD is superimposed on video to be outputted to the external display device by the video output device.

7. The video output device according to claim 1,

wherein the forced output means outputs a menu screen for selecting any of plural playback modes as the OSD when the connected state is detected by the detection means.

8. The video output device according to claim 1,

wherein the detection means detects a CEC connected state in an HDMI standard.

9. An OSD forced display method of a video output device, the method comprising the steps of:

detecting a connected state in which the video output device and a prescribed external display device are connected in a state realizing a mutual device control function which can perform control between devices mutually by a detection means of the video output device;

generating OSD (On Screen Display) for controlling the video output device itself by an OSD generation means when the connected state is detected in the detection step; and

outputting the OSD generated in the step of generating the OSD to the external display device forcibly by a forced output means of the video output device and displaying the OSD on a display portion of the video output device regardless of any setting of the video output device.

10. A video output device comprising:

an OSD generation unit configured to generate OSD (On Screen Display) for controlling the device itself;

a detection unit configured to detect a connected state in which the device is connected to a prescribed external display device in a state realizing a mutual device control function which can perform control between devices mutually; and

a forced output unit configured to output the OSD generated by the OSD generation unit to the external display device forcibly and to display the OSD on a display portion of the external display device regardless of any setting of the device when detecting the connected state by the detection unit.
