Abstract: [Object] To increase the usability for users without decreasing the security level. [Solving Means] A personal computer (PC) 10 is connected to a television receiver (TV) 30 using an HDMI cable 1. When a video signal is transmitted from the PC 10 to the TV 30, a TMDS channel in the HDMI cable 1 is used. A high-speed data line that performs bi-directional communication using predetermined lines of the HDMI cable 1 (e.g., a reserve line and an HPD line) is provided. In PC 10, a firewall is set. When, for example, being connected to the PC 10, the TV 30 transmits a firewall turn-off command to the PC 10. Alternatively, when, for example, performing data transmission using the high-speed data line provided between the TV 30 and the PC 10, the TV 30 transmits a firewall turn-off command to the PC 10. The security level and connectivity can be maintained without troublesome setting performed by the user and, therefore, the usability for users can be increased.

Abstract: 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 apparatus 12 is connected to an image processing apparatus 11 via an HDMI cable 13, the image processing apparatus 11 displays an audio format setup screen on the basis of EDID acquired from the monitor apparatus 12. Only the setup items of the audio signal, which the monitor apparatus 12 can 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 apparatus 11 to the monitor apparatus 12 on the audio format setup screen. The present invention is applicable to, for example, an information processing apparatus outputting an audio signal to a monitor.

Abstract: 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.

Abstract: To effectively use a broadcast reception section (tuner) of a display apparatus such as a television receiver. A personal computer (PC) 10 and a television receiver (TV) 30 are interconnected with one HDMI cable (1). For the transmission of a video signal from the PC 10 to the TV (30), a TMDS channel of the HDMI cable (1) is used. A high-speed data line for executing bidirectional communication using a predetermined line (for example, a reserve line, an HPD line) of the HDMI cable is arranged. Stream data obtained in a broadcast reception section (tuner) of the TV 30 is transmitted to the PC 10 by use of the high-speed data line. The PC 10 records the received stream data or executes image synthesis processing and the line by use of the stream data. The PC 10 transmits the video signal after synthesis processing to the TV 30 over a TDMS channel. On the TV 30, a desktop screen, a reproduced image, a web page, and the like are simultaneously displayed along with a television screen.
