Abstract

According to one embodiment, an information processing apparatus includes: a decoder configured to decode video data to generate a video signal; an adjusting unit configured to execute an adjustment processing on the video signal; an input-output terminal configured to output to an external apparatus the video signal subjected to the adjustment processing by the adjusting unit and to receive identifying information from the external apparatus; and a switching unit configured to select the adjustment processing according to the identifying information.

Claims

1. An information processing apparatus comprising:

a decoder configured to decode video data and to generate a video signal;

an adjusting module configured to execute an adjustment on the video signal;

a terminal configured to output the adjusted video signal to an external apparatus and to receive an identifying information from the external apparatus; and

a switching module configured to select the adjustment according to the received identifying information.

2. The information processing apparatus of claim 1, further comprising a storage module configured to store a plurality of parameter sets for the adjustment, the plurality of parameter sets being associated with a plurality of identifying informations,

wherein the switching module is configured to select a parameter set corresponding to the received identifying information for the adjustment.

3. The apparatus of claim 2, wherein the plurality of parameter sets comprises an initial parameter set, and

wherein the switching module is configured to select the initial parameter set for the adjustment when the plurality of parameter sets do not comprise a parameter set corresponding to the received identifying information.

4. The apparatus of claim 2, further comprising:

a display; and

a display driver configured to control a video signal output to the display and the terminal,

wherein the plurality of parameter sets comprises a display parameter set for the display, and

wherein the switching module is configured to select the display parameter set for the adjustment when the video signal is output to the display.

5. The information processing apparatus of claim 2 further comprising a detecting module configured to detect an output destination of the video signal;

and

a receiver configured to receive the identifying information from the external apparatus through the terminal when the detecting module detects that the output destination has changed.

11. The information processing apparatus of claim 1, wherein the terminal comprises a connector configured to connect to a cable.

6. An information processing apparatus comprising:

a decoder configured to decode video data and to generate a video signal;

an adjusting module configured to execute a first adjustment and a second adjustment on the video signal;

a terminal configured to output the adjusted video signal to an external apparatus and to receive identifying information from the external apparatus; and

wherein the adjusting module is configured to execute the first adjustment when the terminal receives a first identifying information, and

wherein the adjusting module is configured to execute the second adjustment when the terminal receives a second identifying information.

7. The apparatus of claim 6, wherein the adjusting module is configured to execute the first adjustment when the terminal receives a third identifying information.

12. The information processing apparatus of claim 6, wherein the terminal comprises a connector configured to connect to a cable.

8. An information processing apparatus comprising:

a decoder configured to decode audio data and to generate a audio signal;

an adjusting module configured to execute an adjustment on the audio signal;

a terminal configured to output the adjusted audio signal to an external apparatus and to receive an identifying information from the external apparatus; and

a switching module configured to switch the adjustment according to the identifying information.

9. The apparatus of claim 8, further comprising a storage module configured to store a plurality of parameter sets for the adjustment, the plurality of parameter sets being associated with a plurality of identifying informations,

wherein the switching module is configured to select a parameter set corresponding to the received identifying information for the adjustment.

10. The apparatus of claim 8, wherein the plurality of parameter sets comprises an initial parameter set, and

wherein the switching module is configured to select the initial parameter set for the adjustment when the plurality of parameter sets does not comprise a parameter set corresponding to the received identifying information.

13. The information processing apparatus of claim 8, wherein the terminal comprises a connector configured to connect to a cable.
