Method for Processing Broadcast Data in Portable Device, And Computer-Readable Recording Medium with Broadcasting Data Processing Program for the same}

The present invention relates to a method for processing broadcast data in a portable device, and more particularly, to a technique for processing broadcast data of a plurality of mobile TV chips in a portable device.

In general, a broadcast service is a service provided for the purpose of providing all users with a terminal capable of receiving a broadcast service. Such broadcast services are classified into audio broadcasting services such as radio broadcasting providing only voice, video broadcasting services such as television providing voice and video services, and multimedia broadcasting services including voice, video and data services. These broadcast services are based on the analog method, and digital broadcasting is being made in accordance with the breakthrough technology. In addition, the broadcasting service is a multimedia service of a wired network that provides high-definition and high-speed data together with wires, a method of providing a multimedia service by using satellites, and a wired and satellite satellite, instead of the conventional transmission tower. It is being developed in various ways such as using the same time.

As one of these methods, one of the methods of spurring commercial services in recent years is a service of digital multimedia broadcast (DMB) method. This DMB method is based on Digital Audio Broadcasting (DAB) and is based on Eureka-147 (European REserch Coordination Agency progect-147), a technical standard of DAB implemented in Europe. Therefore, hereinafter, the DMB service is referred to generically including DAB service. In addition, the DMB service is divided into a satellite DMB method and a terrestrial DMB method, which provide services using an artificial satellite. The satellite DMB method using an artificial satellite uses a method of multiplexing data using code division multiplexing (CDM) to divide and transmit channels. On the other hand, the terrestrial DMB method uses an orthogonal frequency division multiplexing (OFDM) method to transmit channels separately by multiplexing. Among them, terrestrial DMB broadcasting services are provided free of charge, and anyone can watch high-quality programs as long as they have the equipment to listen to the broadcasting.

Referring to FIG. 5, broadcast data is generated in each of the mobile TV chips 210, 230, and 250 (S511, S513, and S515). In this case, the broadcast data generated by the first mobile TV chip 210 is generated by the first broadcast data, and the broadcast data generated by the second mobile TV chip 230 is generated by the second broadcast data and the third mobile TV chip 250. One broadcast data is referred to as third broadcast data.

Subsequently, the third mobile TV chip 250 transmits the third broadcast data to the second mobile TV chip 230 (S520).

Subsequently, the second mobile TV chip 230 generates a combined information header including information for distinguishing the second broadcast data and the third broadcast data (S531), and combines the second broadcast data with the third broadcast data. The broadcast data is generated (S533) and transmitted to the first mobile TV chip 210 (S535).

Subsequently, the first mobile TV chip 210 adds additional combined information for distinguishing the combined broadcast data and the first broadcast data to the combined information header (S541), and further combined broadcast combining the combined broadcast data and the first broadcast data. Generate data (S543) and transmit it to the AP (300) (S545).

Subsequently, the AP 300 checks the combined information header included in the received additional combined broadcast data (S551), and combines the combined broadcast data with each piece of broadcast data (the first broadcast data and the second using the identified combined information header). The data is parsed into broadcast data and third broadcast data (S553).

Subsequently, the AP 300 processes the parsed broadcast data and outputs the processed broadcast data through the display (S555).

Therefore, according to the present invention, by transmitting broadcast data of another mobile TV chip from one mobile TV chip connected to the AP to the AP, the number of interfaces with a plurality of mobile TV chips can be reduced and the number of interfaces can be reduced. It is possible to lower the production cost of the.
