  • Patent number: 7825931
    Abstract: A repeater comprises an EDID memory to store a control data and a memory control unit. The memory control unit is configured to make access to the EDID memory to read the control data therefrom, store the read control data into the EDID memory and, when access is made to the EDID memory by the set-top box, transfer the control data stored in the EDID memory to the set-top box. In this case, the memory control unit outputs an inhibiting signal to a set-top box to inhibit it from making access to the EDID memory until the completion of an operation of storing the control data from the EDID memory in the set-top box into the EDID memory in the repeater.

  • Publication number: 20050008326
    Abstract: Programming information is received from a portable terminal of a user via a communication network, and whether recording is possible according to the programming information is judged. If recording is possible, the internal state of the video recording apparatus after being programmed, including the remaining amount of available storage, is acquired, and the data of the internal state is transmitted to a Web server on the communication network. An e-mail indicating that the programming information has been registered, and an URL of the Web server, is sent to the portable terminal of the user. The data of the internal state of the video recording apparatus stored in the Web server is sent to the user in response to an instruction from the user via the communication network.
