[Object] To increase the usability for users without decreasing the security level. [Solving Means] A personal computer (PC)is connected to a television receiver (TV)using an HDMI cable. When a video signal is transmitted from the PCto the TV, a TMDS channel in the HDMI cableis used. A high-speed data line that performs bi-directional communication using predetermined lines of the HDMI cable(e.g., a reserve line and an HPD line) is provided. In PC, a firewall is set. When, for example, being connected to the PC, the TVtransmits a firewall turn-off command to the PC. Alternatively, when, for example, performing data transmission using the high-speed data line provided between the TVand the PC, the TVtransmits a firewall turn-off command to the PC. The security level and connectivity can be maintained without troublesome setting performed by the user and, therefore, the usability for users can be increased.

Electronic apparatus and method for turning off firewall of electronic apparatus

The present invention relates to an information processing apparatus, an information processing method, and a program which are capable of rapidly and appropriately setting a format of an audio signal to be output to a display apparatus. When a monitor apparatusis connected to an image processing apparatusvia an HDMI cable, the image processing apparatusdisplays an audio format setup screen on the basis of EDID acquired from the monitor apparatus. Only the setup items of the audio signal, which the monitor apparatuscan receive, are enabled in the audio format setup screen. A user selects a format of the audio signal to be supplied from the image processing apparatusto the monitor apparatuson the audio format setup screen. The present invention is applicable to, for example, an information processing apparatus outputting an audio signal to a monitor.

Apparatus and method of processing information and program

An information processing apparatus is provided that includes a control unit to execute an operating system and selectively output a first video signal or both the first video signal and a first audio signal, an external input unit to which an external content signal containing a second video signal and a second audio signal transmitted from an external apparatus is input, and a reproduction state switch control unit to selectively switch a first reproduction state for reproducing the first video signal or both the first video signal and the first audio signal, and a second reproduction state for reproducing the second video signal and the second audio signal, wherein, if input of the external content signal to the external input unit is detected during a reproduction standby state, the reproduction state switch control unit switches the reproduction standby state with the second reproduction state.

Information processing apparatus and program

An information-processing apparatus comprises an acquisition unit configured to acquire information about a communication-method type from a display device connected to the information-processing apparatus, a determination unit configured to determine whether or not the display device is adapted to receive data on digital contents by using a predetermined copyright-protection technology based on the communication-method-type information, a conversion unit configured to convert an image quality of the digital contents based on the determination result, and an output unit configured to transmit the converted digital contents to the display device.

Information-processing apparatus, information-processing method, program, and storage medium

A data recording/reproducing apparatus wherein various data to be used for maintenance are measured, and parameters required for analysis of the maintenance data are prerecorded to realize prediction of the service life of a semiconductor laser and detection of occurrence of any trouble that may be derived therefrom. In this apparatus where data are recorded in and/or reproduced from a recording medium, the internal state of the apparatus is measured, then any abnormal state in the apparatus is detected on the basis of abnormal state decision data, and the detected state is transmitted to an external information processor. The apparatus comprises a means for measuring first data relative to the apparatus; a first memory means for storing second data to make a decision as to an abnormal state of the measured first data; a means for generating third data relative to maintenance of the apparatus on the basis of the first and second data; and an output means for delivering the third data as an output.

Recording/reproducing apparatus, and method of detecting state thereof

A recording/reproducing apparatus is disclosed which records and reproduces data to and from an optical disc using a laser beam. In accordance with an error rate detected from the data that have been recorded and reproduced to and from the optical disc, the apparatus controls the intensity of the laser beam in order to ensure error-free recording of the data.

Method and apparatus for controlling the intensity of a laser beam used to record/reproduce data to/from an optical disc

According to the present invention, maintenance data about a plurality of distribution terminal devices which are different from each other in frequency with which they are in use and circumstances under which they are in use are transmitted to a host computer, whereby a lifetime of a semiconductor laser can be predicted and an occurrence of a trouble can be detected without receiving information from a user or shops in which the distribution terminal devices are installed.
