Abstract

The invention provides a multi-carrier frequency cooperative transmission method. The multi-carrier frequency cooperative transmission method comprises the following steps: mapping service data to be transmitted to different logic channels according to service attributes; and mapping the service data on different logic channels to different carrier frequencies for transmission. According to the multi-carrier-frequency cooperative transmission method provided by the invention, multi-channel multi-carrier-frequency cooperative transmission of service data can be realized based on service attributes, so that video receiving with upgradable quality is realized.

Description

technical field [0001] The present invention relates to the technical field of digital communication, in particular to a method for coordinated transmission of multiple carrier frequencies. Background technique [0002] With the rapid development of digital technology and information technology, the world has entered the era of digitization, informationization and networking, and digital multimedia broadcasting has also developed rapidly. At this stage, there are mainly the following types of digital TV broadcasting standards in the world: Digital Video Broadcast (DVB) standard in Europe, Advanced Television Systems Committee (ATSC) standard in the United States, and Integrated Services Digital in Japan. Broadcasting (Integrated Service Digital Broadcasting, ISDB) standard. China's digital television began to develop under the atmosphere of increasing international digitization, and launched the Digital Television Terrestrial Multimedia Broadcasting (DTMB) standard and Chin...
