摘要:
A function managing apparatus allows a user to avoid a fault likely to occur in a user terminal before a new function is installed on the user terminal. A function managing apparatus for communicating with a user terminal is provided. Specifically, the function managing apparatus includes a receiving unit, predicting unit, and alerting unit. The receiving unit receives from the user terminal the new function ID identifying the new function to be installed on the user terminal, and the installed function IDs identifying one or more functions previously installed on the user terminal. The predicting unit specifies the new function and one or more installed functions based on the new function ID and installed function IDs received by the receiving unit, and predicts the result when the new function is installed on the user terminal. The alerting unit notifies the user terminal of the prediction result of the predicting unit.
摘要:
To provide a terminal device capable of independently determining an occurrence of an event, and autonomously processing a service in response to the event. An event detection section (205) detects a predetermined event. A service retrieving section (206) retrieves a service corresponded to the detected event. A service execution section (207) determines an application program related to the retrieved service, and another terminal device which cooperatively executes the application program. Then, the service execution section (207) instructs an application management section (203) and an application execution section (204) of the own terminal device and the other terminal device to obtain and execute the program.
摘要:
A memory card 13 includes wireless network communication unit for having electronic equipment to access a storage server 11 on a network. The storage server 11 includes at least a non-authentication area 111. Data such as contents is written into a non-authentication area of the memory card 13 or the non-authentication area 111 of the storage server 11. In other words, an area of a storage area to which data can be written is expanded by the non-authentication area 111 of the storage server 11. Thus, the non-authentication area of the memory card 13 increases apparently. Encoding key used for encoding and decoding contents protected by copyrights is written to an authentication area on the memory card 13. Anyone can access content data in the non-authentication area 111 of the storage server 11, but an encoding key required for decoding the content is in the memory card 13. Thus, only a person who has the memory card 13 and valid electronic equipment can decode, reproduce and output the content using the encoding key. In this way, the storage capacity of the memory card 13 can be increased apparently while security of data protected by copyrights is guaranteed.

In a transmission device (2): a controller (2a) performs a control of reading, from information regarding video specification, first information indicating whether a reception device is capable of intermittent reception of receiving a video signal at a timing that causes certain number of frames to be intermittent, and, when the reception device can perform intermittent reception, multiplexing, to the video signal during a blanking period of the video signal to be updated, an enable signal indicating the present video signal is to be enabled and second information indicating that transmission of the video signal will not resume unless the video signal is updated; and a transmitter (2d) transmits the video signal that is to be updated and then does not resume transmission of the video signal unless the video signal is updated.
摘要:
In a signal transmitter and a signal receiver, a multiplexing part multiplexes a video signal and a time-base-compressed audio signal on the basis of a multiplexing control signal to transmit the multiplexed signal through a data line in the signal transmitter. Further, a demultiplexing part demultiplexes a video/audio multiplexed signal received through the data line into the original video signal and audio signal by a demultiplexing control signal in the signal receiver. According to the so-configured signal transmitter and signal receiver, it is possible to realize a signal transmission system compliant with the DVI standard, in which the audio signal as well as the video signal can be transmitted.

A video signal and an audio signal are time division multiplexed, encrypted, and transmitted. A transmission side time-compresses the audio signal, multiplexes, encrypts, and transmits the time-compressed audio signal in a blanking period of the video signal. Control is performed using an audio signal data enable signal ADE, and an audio signal/video signal switch signal.
摘要:
A signal transmitter and a signal receiver comprises a time base compression part (101) for compressing an audio signal on a time base to output the compressed signal as a time base compressed audio signal and a multiplexing part (102) for multiplexing a video signal, a control signal, and the time base compressed audio signal to output the multiplexed signal to the external as a video/audio control multiplexed signal. The thus constituted signal transmitter and the signal receiver realize a signal transmission system for multiplexing and transmitting the video signal, audio signal, and control signal, for consequently transmitting high-quality diverse digital audio signals without conversion into an analog signal, and for transmission at high speed with minimal error.
