Here, as in the above description, the broadcast information web page may be output to an information dedicated window for simultaneously providing broadcast information separately from the dedicated window of the TV receiving card program.

Next, a case where the user requests a reservation request is as follows. 4 is a diagram illustrating an embodiment of a reservation viewing process in a bidirectional broadcast linking method according to the present invention.

The user who looked at the broadcast information search web page clicks the reservation icon (84 of FIG. 2B) on the web browser and requests a reservation request (S300). Then, an auxiliary web page presenting the information on the reservation viewing is presented to the user, and the reservation information input by the user through the auxiliary web page is stored in the user terminal 10 and the broadcasting information providing server 30 (S310). . However, in order to easily store a plurality of subscribers, it is preferably stored in the reservation DB 40.

The interactive broadcast linked program selectively checks the reservation information at predetermined intervals according to whether the user terminal is connected to the broadcast information providing server 30.

That is, if the user terminal 10 is connected to the broadcast information providing server 30, the broadcast information providing server 30 is searched. If the user terminal 10 is not connected, the user terminal 10 is searched to read the reservation information (S320). In operation S330, it is determined whether the broadcast start time is reached.

If it is determined that the broadcast start time is not determined, the reservation information is continuously read at a predetermined cycle, and if it is determined that the broadcast start time is determined, it is determined whether the program for the TV receiving card is driven.

It is determined whether the program for the TV receiving card is running (S340). If not, the program for the TV receiving card is driven (S345), and the channel change command is transmitted to the program for the TV receiving card (S350). If it is determined in S340 that the program for the TV receiving card is being executed, the channel change command is transmitted to the program for the TV receiving card (S350).

The program for the TV receiving card changes the channel of the TV receiving card according to the transmitted channel change command (S360), and outputs the corresponding channel to the dedicated window 70 of the program for the TV receiving card (S370). Then, receiving the broadcast information web page of the channel from the broadcast information providing server 30 and outputs it on the web browser (S380).

As in the viewing channel change, when the user terminal 10 and the broadcasting information providing server 30 are in an offline state, the user terminal 10 and the broadcasting information providing server 30 are received from the broadcasting information providing server 30 when they are online and are cached in the user terminal 10. The broadcast information web page is displayed on a web browser.

Therefore, the user can watch the broadcast program of the reserved channel at the reservation time. In the above description, the broadcasting information web page is output to the web browser as an example. However, the broadcasting information web page may be configured to be output in an information dedicated window for simultaneously providing broadcasting information separately from the dedicated window of the TV receiving card program. .
