Information processing apparatus, information processing method, and computer program product
An information processing apparatus is compatible with a High-Definition Multimedia Interface (HDMI) and serves as a sink device. The information processing apparatus comprising: a storage unit that stores therein recommended device information that is about a recommended source device and that includes a logical address and a vendor ID of the source device; and a controlling unit that obtains information about a logical address and a vendor ID of a source device connected to the information processing apparatus, compares the obtained information with the recommended device information, and if it is determined that the connected source device is not the recommended source device, performs control so as to allow the connected source device to be used while limiting a usage range of video and audio outputs.
1. An information processing apparatus that is compatible with a High-Definition Multimedia Interface (HDMI) and serves as a sink device, comprising:
a memory that stores therein recommended device information of a recommended source device, which includes a logical address and a vendor ID of the recommended source device; and
processing circuitry that obtains information about a source logical address and a source vendor ID of a source device connected to the information processing apparatus, compares the obtained information with the recommended device information, and when it is determined that the connected source device is not the recommended source device, causes a display to display information indicating the determination and an inquiry inquiring whether a user wants to limit a usage range of video and audio outputs, and when the user indicates that the usage range should be limited, performs control so as to allow the connected source device to be used while limiting the usage range of the video and audio outputs.
2. The information processing apparatus according to claim 1 , wherein the processing circuitry realizes the limiting by discarding data received from the connected source device.
3. The information processing apparatus according to claim 1 , wherein the processing circuitry realizes the limiting by lowering a quality of video and audio data transmitted from the connected source device by rewriting EDID data of the information processing apparatus.
4. An information processing method implemented by an information processing apparatus that is compatible with a High-Definition Multimedia Interface (HDMI) and serves as a sink device, the information processing method comprising:
obtaining, by processing circuitry of the information processing apparatus, information about a source logical address and a source vendor ID of a source device connected to the information processing apparatus;
comparing, by the processing circuitry, the obtained information with recommended device information that is stored in a memory of the information processing apparatus, that is about a recommended source device, and that includes a logical address and a vendor ID of the recommended source device; and
causing, by the processing circuitry, when it is determined that the connected source device is not the recommended source device, a display to display information indicating the determination and an inquiry inquiring whether a user wants to limit a usage range of video and audio outputs, and when the user indicates that the usage range should be limited, performing control so as to allow the connected source device to be used while limiting the usage range of the video and audio outputs.
5. A computer program product comprising a non-transitory computer-readable medium containing an information processing program, the program causing processing circuitry of an information processing apparatus that is compatible with a High-Definition Multimedia Interface (HDMI) and serves as a sink device, to perform:
obtaining information about a source logical address and a source vendor ID of a source device connected to the information processing apparatus;
comparing the obtained information with recommended device information that is stored in a memory of the information processing apparatus, that is about a recommended source device, and that includes a logical address and a vendor ID of the recommended source device; and
causing, when it is determined that the connected source device is not the recommended source device, a display to display information indicating the determination and an inquiry inquiring whether a user wants to limit a usage range of video and audio outputs, and when the user indicates that the usage range should be limited, performing control so as to allow the connected source device to be used while limiting the usage range of the video and audio outputs.
6. The information processing apparatus of claim 1 , wherein the processing circuitry is further configured to not limit the usage range of the video and audio outputs, when the user indicates that the usage range should be limited.
