System for reducing the work load of a terminal for receiving Digital Multimedia Broadcast (DMB) and method of transmitting version information relating to Program Specific Information and Service Information (PSI/SI) data and of parsing PSI/SI data

摘要

Provided are a DMB system for reducing a working load of a DMB receiving terminal, a method of transmitting PSI/SI version information, and a method of parsing PSI/SI. When PSI/SI is generated, a DMB station receives version information of the PSI/SI from each of PSI/SI generators, generates PSI/SI version information, and transmits the generated PSI/SI version information through a specific channel. Then, the DMB receiving terminal receives the PSI/SI version information, compares the received PSI/SI version information to stored PSI/SI version information, and parses received PSI/SI according to the comparison result. Accordingly, by controlling the DMB receiving terminal to parse PSI/SI only if the PSI/SI has been modified, an unnecessary working load due to the parsing can be reduced.
