Information Processing System, Information Processing Apparatus, and Information Processing Method

An information processing system comprising:

• a conversion adaptor having a video input connector that complies with a first standard and a video output connector that complies with a second standard;
• and
• an information processing apparatus configured to be connected to the conversion adaptor, the apparatus including:
• a video output port complying with the first standard for connection of the video input connector;
• an image processing module configured to output a first signal that complies with a logical layer of the first standard when the video input connector is not connected to the video output port, the image processing module being configured to output a second signal that complies with a logical layer of the second standard when the video input connector is connected to the video output port;
• and
• a bias module connected to the video output port and the image processing module and configured to output a third signal to the video output port, the bias module being configured to change physical layer information of the first signal or the second signal.

An information processing method for an information processing apparatus comprising a video output port that complies with a first standard and to which a conversion adaptor having a video input connector that complies with the first standard and a video output connector that complies with a second standard is connected, the method comprising:

• connecting the video input connector to the video output port;
• generating a first signal that complies with a logical layer of the second standard;
• and
• generating a second signal by changing physical layer information of the first signal, the second signal being supplied to the video output port.
