Abstract:
Recording and playback device (120) for recording and playing back data on or from an optical disk (90a) by use of a laser beam. Dependent on the error rate resulting from recording or playback of data, the device controls the laser beam intensity. An Independent claim is made for an optical recording and playback method in which laser beam intensity is adjusted according to the measured error rate.
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.

PROBLEM TO BE SOLVED: To effectively use a broadcast receiver (tuner) included in a display device of, for example, a television receiver. SOLUTION: A personal computer (PC) 10 and a television receiver (TV) 30 are connected to each other with one HDMI cable 1. A TMDS channel in the HDMI cable 1 is used to transmit a video signal from the PC 10 to the TV 30. A predetermined line (for example, a reserve line or an HPD line) in the HDMI cable is used as a high-speed data line for performing bidirectional communication. Stream data obtained in the broadcast receiver (tuner) of the TV 30 are transmitted to the PC 10 using the high-speed data line. The PC 10 records the received stream data or performs an image synthesizing process and other processes using the received stream data. The PC 10 transmits the synthesized video signal to the TV 30 over the TDMS channel. On the TV 30, a desktop screen, a reproduced image, a web page, etc. are displayed simultaneously with a television screen. COPYRIGHT: (C)2009,JPO&INPIT

Abstract:
PROBLEM TO BE SOLVED: To provide an information processing apparatus and program which make it possible to reproduce video or sound expressed by a signal transmitted from an external apparatus without depending on an executing state of an operating system to improve user convenience. SOLUTION: 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 to the second reproduction state.

PROBLEM TO BE SOLVED: To speedily and properly set a format of a voice signal to be outputted to a display device. SOLUTION: When a monitor 12 is connected to an image processor 11 via a HDMI cable 13, the image processor 11, on the basis of an EDID acquired from the monitor 12, makes the monitor 12 display an audio format setting screen, in which only the setting items of the voice signal acceptable to the monitor 12 is selectable, and makes the user select the format of the voice signal that is to be supplied to the monitor 12 from the image processing device 11. For example, the present invention is applicable to an information processor that outputs voice signal to a monitor. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To enable a user to freely utilize digital content with high image quality. SOLUTION: When an application for operating a receiver is activated in a personal computer connected to the receiver via USBI/F51, a microcomputer 53 controls a switch 56 on the basis of information to be transmitted from the personal computer to extract the data of any of content received via a tuner 54 or content acquired via iLINKI/F55, and controls a converter 57 as necessary to convert the image quality of content. Then, an image compositing unit 59 composites the data of the content with a slave screen of GUI for operating the receiver of the personal computer to be inputted via DVI/IF58. This apparatus is applicable to a digital tuner. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide a digital content with the optimum quality while protecting the copyright of the digital content. SOLUTION: An HDCP control unit 60 determines whether a monitor to be connected via a DVII/F61 is a monitor compatible with HDCP, and a result of determination is reported to a microcomputer (MC) 53. If the monitor to be connected is not the monitor compatible with the HDCP, the MC 53 sets a converter 57 at an ON state. When data received via a tuner 54 or acquired via an iLINKI/F55 and to be supplied from a switch 56 are the data of an HD image, the converter 57 converts the data into data of and SD image. This apparatus is applicable to a digital tuner. COPYRIGHT: (C)2006,JPO&NCIPI
