Problems solved by technology

In the case of transmitting multimedia data using an IP tunnel in the conventional DAB system, the DAB transmitter 900 or the DAB receiver 902 cannot identify what is included in the IP packet corresponding to the multimedia data, that is, whether the IP packet is a file, a video stream, or an audio flow
Therefore, the DAB transmitter 900 or the DAB receiver 902 is only used as a channel for transmitting IP packets, but cannot adaptively process the transmitted multimedia data

Abstract

Provided are a method and apparatus for providing an IP datacasting service in a digital broadcasting system. The method for providing the IP datacasting service in the digital broadcasting system includes: generating service configuration information indicating that the IP datacasting service is provided; packetizing data to be transmitted and generating IP packet data; formatting information related to a configuration of the IP packet data by using a predetermined protocol; and transmitting the service configuration information, the IP packet data, and the information related to the configuration of the IP packet data through separate channels, respectively. Accordingly, various information related to transmitted multimedia data is transmitted together with the multimedia data, so that an IP datacasting function for appropriately processing the multimedia data according to the type of the multimedia data is provided.

Description

technical field [0001] The present invention relates to a Digital Audio Broadcasting (DAB) system, and more particularly, to a method and apparatus for providing IP data broadcasting services in the DAB system. Background technique [0002] Digital Audio Broadcasting (DAB) is a broadcasting system developed in Europe to digitize existing AM and FM radio broadcasts. DAB provides audio and data services and is also known as "EUREKA (EUREKA) 147 DAB". [0003] FIG. 1 shows the structure of a data frame 800 in the DAB system. [0004] Referring to FIG. 1 , a DAB frame 800 includes: a synchronization channel 802 , a fast information channel (FIC) 804 and a main service channel (MSC) 806 . [0005] The synchronization channel 802 includes information for synchronization used when the DAB frame 800 is demodulated. FIC804 includes various control information, urgent data and service information that need to be transmitted quickly. Signals sent over FIC ca...
