Abstract

In a method of transmitting broadcasting signals, a transmission frame has the same configuration as that of the existing terrestrial DMB signal. A transmission frame including a base layer service stream is modulated to a base layer, and a transmission frame including an enhancement layer service stream is modulated to an enhancement layer. The enhancement layer service stream is composed of additional data that is not included in the base layer service stream, in order to provide an enhancement layer service. In this way, the method can provide a high-quality service requiring high transmission efficiency while being compatible with the existing terrestrial DMB system. The high transmission efficiency means a higher data transfer rate than that of the existing terrestrial DMB system.

Description

technical field [0001] The present invention relates to a method and device for transmitting digital broadcast signals and a method and device for receiving digital broadcast signals. Specifically, the present invention relates to a method and device for transmitting digital broadcast signals and a method and device for receiving digital broadcast signals, which can provide high-quality services requiring high transmission efficiency and ensure backward compatibility with existing terrestrial DMB signals. compatible. High transmission efficiency means a higher data transmission rate than existing DMB systems. [0002] The present invention is supported by the IT R&D project of MIC / IITA [2006-S-017-02, Research and development of advanced transmission technology for terrestrial DMB systems]. Background technique [0003] A terrestrial DMB (Digital Multimedia Broadcasting) system is constituted by adding a standard for providing video services to the Eureka-147DAB system, an...
