Abstract

According to one embodiment, there is provided an information processing apparatus connectable to a TV receiver via a digital image interface, including: a display device; a plurality of image output terminals including a digital image output terminal associated with the digital image interface; an image output selection section configured to select an image output terminal for output to the TV receiver from the plurality of image output terminals; and an image output section configured to output image data of an image being displayed on the display device and control data for control of the TV receiver to the TV receiver through the selected digital image output terminal, the image output section configured to generate the control data based on an operation state of the information processing apparatus.

Claims

1. An information processing apparatus configured to connect to a TV receiver via a digital video interface, the apparatus comprising:

a display device;

a plurality of video output terminals comprising a digital video output terminal associated with the digital video interface;

a video output selection section configured to select a video output terminal for output to the TV receiver from the plurality of video output terminals; and

a video output section configured to output video data of a video being displayed on the display device and control data for control of the TV receiver to the TV receiver through the selected digital video output terminal, the video output section configured to generate the control data based on an operation state of the information processing apparatus.

2. The information processing apparatus of claim 1, wherein the TV receiver comprises a plurality of video input terminals;

and

wherein the video output section is configured to output to the TV receiver control data for selecting a video input terminal associated with the digital video interface from the plurality of video input terminals when the digital video output terminal is selected by the video output selection section.

3. The information processing apparatus of claim 1, wherein the video output section is configured to output to the TV receiver control data for powering on the TV receiver if the TV receiver is not powered when the digital video output terminal is selected by the video output selection section.

4. The information processing apparatus of claim 1,

wherein, the TV receiver is configured to have a broadcast mode for realizing video quality and a display area that are suitable for a broadcast video and a PC mode for realizing video quality and a display area that are suitable for a video of the information processing apparatus;

and

wherein the video output section is configured to output to the TV receiver control data for switching from the broadcast mode to the PC mode when the digital video output terminal is selected by the video output selection section in a state that a video of the information processing apparatus is being displayed on the display device.

5. The information processing apparatus of claim 1,

wherein the TV receiver is configured to have a broadcast mode for realizing video quality and a display area that are suitable for a broadcast video and a PC mode for realizing video quality and a display area that are suitable for a video of the information processing apparatus;

and

wherein the video output section is configured to output to the TV receiver control data for setting the broadcast mode if a moving picture is being displayed in a full screen of the display device and control data for setting the PC mode if a moving picture is being displayed in a window of the display device when the digital video output terminal is selected by the video output selection section.

6. The information processing apparatus of claim 1,

wherein each of the information processing apparatus and the TV receiver has a plurality of video quality modes for moving picture display;

and

wherein the video output section is configured to output to the TV receiver control data for selecting a video quality mode corresponding to a video being displayed on the display device when the digital video output terminal is selected by the video output selection section.

7. A method for controlling a TV receiver by an information processing apparatus comprising a display device, comprising:
