System and Method for controlling audience reservation of digital multimedia broadcasting}

The present invention relates to a system and method for controlling viewing reservation of digital multimedia broadcasting, and more particularly, when a text message received at a communication terminal is a broadcast viewing recommendation message, a start / end time of a program included in the message is compared with a current time. Compare and determine the current broadcast status of the program, and generate and output one of the viewing availability query message, the viewing reservation query message, and the broadcast end indication message according to the determined broadcasting status to the DMB broadcast through the recommended message. The present invention relates to a system and method for watching reservation control of a digital multimedia broadcasting that enables a user to immediately watch a corresponding program by entering a DMB or DMB.

As electronic and communication technologies develop, digital broadcasting such as digital terrestrial TV broadcasting, digital wired cable broadcasting, and digital multimedia broadcasting (DMB) are becoming more common than conventional terrestrial broadcasting and cable broadcasting. There is a trend.

Analog broadcasting is a limited broadcasting method that transmits programs produced by broadcasters unilaterally to viewers, and viewers simply select one of three or four channels during the broadcast time and watch the broadcasted program.

Recently, due to the introduction of wired cable broadcasting, broadcast programs have diversified and broadcast channels have been diversified into several channels, but this is also a limited broadcast in that one can watch broadcast programs received on TV.

However, digital broadcasting can provide HD (High Density) video or CD (Compact Disk) level sound, and broadcast programs can be connected and connected with other digitized media such as personal computers (PCs) or digital cameras. It is a broadcast method that can be used.

Another advantage of the above-described digital broadcasting is that the broadcast program is transmitted as digital multimedia data, so that while broadcasting the broadcast program, information about the broadcast program or broadcast program on a daily, weekly or monthly basis is converted into data and transmitted together with the broadcast program. The viewer who receives the digital broadcast program and watches the broadcast program may not only watch the broadcast program that is transmitted unilaterally, but may also check the broadcast information such as the type of the broadcast program, the broadcast time, and the detailed information of the broadcast program. Therefore, the broadcast can be watched efficiently.

A program provider (PP) for generating a broadcast program, that is, broadcast content in digital broadcasting, generates the information on the above-described broadcast as metadata and transmits the TV, mobile terminal, viewer, through a communication medium such as a communication network or satellite. It transmits to a receiving terminal such as a set top box, and the receiving terminal provides the viewer with broadcasting information by outputting information included in the metadata received through the installed EPG program on the screen.

On the other hand, one of the most prominent features of digital broadcasting is that two-way communication between the viewer and the broadcaster is possible.

That is, when using digital broadcasting, the viewer checks the type of broadcasting program, broadcasting time, detailed information of the broadcasting program, and the like through a receiving terminal, and searches for and selects a desired broadcasting program so that the schedule can be viewed at a desired time. ) Can be adjusted.

In addition, the program provider (PP) transmits a broadcast viewing invitation message (URL SMS) as shown in FIG. 1 to the user terminal, and selects 'OK' if the user wants to enter the DMB or 'NO' if not. It is supposed to be. At this time, the text content of the URL SMS is fixed. When the user selects 'confirmation', the user may enter the DMB to check whether the corresponding program is on the air, before or after the broadcast, and the user may make a reservation or watch.

In the case of recommending viewing DMB using the conventional SMS as described above, it is difficult to check whether the DMB program recommended by the user at the time of checking the SMS content is being broadcast, before the broadcast is started, or when the broadcast is over.

In addition, there is a disadvantage that can be confirmed only if the DMB enters whether to watch a program, viewing reservations, or broadcast time has been received.

In addition, in case of viewing reservations / immediate viewing of a program that is recommended for viewing, there is an inconvenience in that the user enters the DMB and schedules viewing / viewing.

The present invention has been made to solve the problems described above, and when the SMS is shown to the user by including the program broadcast start time and the end time in the text content sent to the URL SMS, the SMS in accordance with the broadcast, before the broadcast, the end of the broadcast An object of the present invention is to provide a control system and method for watching a reservation of a digital multimedia broadcasting to change and display the text content of the digital multimedia broadcasting.
