FIG. 4 illustrates a TCP / IP layer of a mobile terminal constituting the network of FIG. 1.

5A and 5B illustrate a process of providing a mobile broadcast service to a mobile terminal based on the network of FIG. 1 according to an embodiment of the present invention.

The present invention relates to a mobile broadcasting service, a central control system and a home media server providing the same. More specifically, the present invention relates to TV broadcasting data provided from wired cable or satellite broadcasting service providers that are used in most homes. The present invention relates to a mobile broadcast service method and system for providing a real time streaming method to a mobile terminal (mobile phone, PDA, WiBro terminal, etc.) of the mobile broadcast service subscriber connected in a to-point method.

The general mobile broadcasting service is provided in two ways. One is the satellite digital mobile broadcasting service (hereinafter referred to as "satellite DMB"), which provides broadcasting via satellite, and the other is the terrestrial digital mobile broadcasting service (hereinafter referred to as "terrestrial DMB"), which relays broadcasts through a transmission tower on the ground. have. However, the mobile broadcast services have various problems.

The first problem is the problem of content acquisition. In the mobile broadcasting service, securing stable contents is a key to service success. In the case of satellite DMB, only limited contents are provided due to the refusal of retransmission of terrestrial programs in the terrestrial DMB, a competitive service. Terrestrial DMB is struggling to invest in the production of separate contents for this service only by the free service model by the publicity. In addition, terrestrial DMB has a problem in the retransmission of programs already secured by more terrestrial broadcasters due to the limited radio frequency band.

The second problem is that the national network service area is not secured. In the case of satellite DMB, the nationwide network service was provided from the beginning of service due to the nature of transmission technology. However, in the case of terrestrial DMB, there are still many obstacles to overcome in order to provide the nationwide network service.

Third, there is a problem of radio shadow areas. In the case of satellite DMB, the shadow area problem was largely solved by installing a gap filler, but in the case of terrestrial DMB, it was not possible to install a repeater in order to minimize investment costs in order to maintain a free service policy. Is hardly caught, and services are not provided properly due to radio interference in urban areas.

Fourth is an expensive plan. Terrestrial DMB service is provided free of charge, but in case of satellite DMB service fee is expensive to recover the repeater installation cost, satellite launch cost, and maintenance cost.

Fifth, there is no revenue model for mobile service providers. Satellite DMB and terrestrial DMB provide services using mobile radio frequencies and other dedicated frequency bands. As a result, mobile service providers provide services to customers such as DMB (satellite DMB and terrestrial DMB) actual subscriber attraction, terminal dissemination, and billing agency, but it does not provide mobile operators with the actual profit model. Even if the DMB service is activated, it can only benefit from additional aspects such as the penetration rate of new mobile phones (DMB phones) and new subscribers, and cannot find profit models such as subscription fees and data usage fees, which are practical service aspects.

Lastly, the problem of handset spread. The DMB service is provided through some dedicated terminals, navigation complex terminals, and mobile phone combined terminals. Among them, the penetration rate of mobile handset-type terminals is the majority, but in the case of mobile handset-type handsets, very few mobile phones with DMB functions are included.

The technical problem to be achieved by the present invention is to provide a mobile mobile broadcasting service that can solve the problems of the above-mentioned DMB service by providing the cable terminal and satellite broadcasting to the mobile terminal in real time through the next generation mobile communication network and portable Internet network.
