Abstract

A remote control system in which an instruction from a remote terminal is transmitted to a controlled device through a remote control device. Device unique data which is information specific to the controlled device is stored in the remote control device or the controlled device. The remote control device generates WEB display data to be displayed on the remote terminal based on a device type of the controlled device and the device unique data. Alternatively, the remote control device generates WEB display data based on the device unique data stored in the controlled device. Thus, even when a new type of controlled device is developed, or even when the function for the controlled device is extended, it does not need to modify programs for achieving functions of the remote control device. Accordingly, it facilitates a change of an operational screen of the terminal in response to those changes.

Claims

1. A remote control system which includes a controlled device capable of being controlled through a network and a remote controller which transmits control information based on a user instruction provided on a remote terminal, distinct from the remote controller, to the controlled device through the network, wherein

a) the controlled device includes:

a first communication controller that communicates with the network; and

a device type storage that stores device type information representing a type of the controlled device,

b) the remote controller includes;

a second communication controller which communicates with the remote terminal and the remote controller over the network;

a device type decisioner that receives the device type information from the device type storage of the controlled device which is designated by an instruction received from the remote terminal through the first and second communication controllers;

a device specific data storage that stores device specific data which represents information of an operation specific to the controlled device and is provided independently of a program for realizing functions of the remote control system;

a device data analyzer that generates data necessary for generating a WEB display on the basis of the device specific data stored in the device specific data storage and the device type information received by the device decisioner; and

a WEB display data generator that generates WEB display data utilized to generate the WEB display, on the basis of the data generated by the device data analyzer,

wherein the device data analyzer extracts data specific to the controlled device on the basis of the received device type information, from the device specific data stored in the device specific data storage; and

the WEB display data generator generates the WEB display data on the basis of the specific data extracted by the device data analyzer, and transmits the WEB display data to the remote terminal through the second communication controller.

3. The remote control system according to claim 1, wherein the controlled device comprises a video recorder which records a received broadcast program.

4. The remote control system according to claim 3, wherein the device specific data comprises information related to a recording operation.

2. A remote control system which includes a controlled device capable of being controlled through a network and a remote controller which transmits control information based on a user instruction provided on a remote terminal, distinct from the remote controller, to the controlled device through the network, wherein

a) the controlled device includes:

a first communication controller that communicates with the network; and

a device specific data storage that stores device specific data which represents information of an operation specific to the controlled device and is provided independently of a program for realizing functions of the remote control system,

b) the remote controller includes;

a second communication controller that communicates with the remote terminal and the remote controller over the network;

a device data memory that receives the device specific data from the device specific data storage of the controlled device which is designated by an instruction received from the remote terminal through the first and second communication controllers, and stores the device specific data;

a device data analyzer that generates data necessary for generating a WEB display on the basis of the device specific data stored in the device specific data storage; and

a WEB display data generator that generates WEB display data utilized to generate the WEB display, on the basis of the data generated by the device data analyzer, and transmits the WEB display data to the remote terminal through the second communication controller.

9. The remote control system according to claim 2, wherein the controlled device comprises a video recorder which records a received broadcast program.

10. The remote control system according to claim 9, wherein the device specific data comprises information related to a recording operation.

5. A remote control method for a remote control system including a controlled device capable of being controlled through a network and a remote controller which transmits control information based on a user instruction provided on a remote terminal, distinct from the remote controller, to the controlled device through the network, the remote control method comprising:

storing device type information representing a type of the controlled device in the controlled device;

receiving the stored device type information from the controlled device;

storing device specific data which represents information of an operation specific to the controlled device in the remote controller which is provided independently of a program for realizing functions of the remote control system;

extracting data specific to the controlled device from the stored device specific data on the basis of the received device type information, by the remote controller;

generating WEB display data utilized to generate a WEB display, on the basis of the extracted specific data, by the remote controller; and

transmitting the WEB display data to the remote terminal, by the remote controller.

7. The remote control method according to claim 5, wherein the controlled device comprises a video recorder which controls a recording operation of a received broadcast program.

8. The remote control method according to claim 7, wherein the device specific data comprises information related to the recording operation.

6. A remote control method for a remote control system including a controlled device capable of being controlled through a network and a remote controller which transmits control information based on a user instruction provided on a remote terminal, distinct from the remote controller, to the controlled device through the network, the remote control method comprising:

storing device specific data which represents information of an operation specific to the controlled device in the controlled device and which is provided independently of a program for realizing functions of the remote control system;

receiving the stored device specific data from the remote control system, by the remote controller;

generating a WEB display data utilized to generate a WEB display, on the basis of the received device specific data by the remote controller; and

transmitting the WEB display data to the remote terminal by the remote controller.

11. The remote control method according to claim 6, wherein the controlled device comprises a video recorder which controls a recording operation of a received broadcast program.

12. The remote control method according to claim 11, wherein the device specific data comprises information related to the recording operation.
