Abstract

A method and apparatus for supporting a priority transmission of broadcasting data in a transmitter of a digital broadcasting system. A determination is made as to whether a priority transmission of one broadcasting service to be provided is supported. If the service supports the priority transmission, a plurality of subchannels to be transmitted for the service are set and a priority of the data to be mapped to the plurality of subchannels is set. The data of the broadcasting service is mapped to the plurality of subchannels according to the priority. Data streams mapped to the plurality of subchannels are encoded in different encoders and the encoded data streams are transmitted.

Description

[0001] priority [0002] This application was filed at the Korean Intellectual Property Office on April 27, 2005 under 35 U.S.C. Section 119, assigned serial number 2005-35073 and entitled "For Supporting Priority Data in a Transmitter of a Digital Audio Broadcasting System method and apparatus for transmission", the contents of which are hereby incorporated by reference. technical field [0003] The present invention relates generally to Digital Audio Broadcasting (DAB) systems and terrestrial Digital Multimedia Broadcasting (DMB) systems, and more particularly to a method and apparatus for transmitting data of one of the first services so that when audio is provided from a DAB transmitter , data and video services, the code rate can be used differently according to the data priority. Background technique [0004] The Digital Audio Broadcasting (DAB) transmitter is a transmitter of a DAB system commonly referred to as the European Research Coordination Agency (Eureka) 147 ...
