METHOD AND APPARATUS FOR TRANSMITTING/RECEIVING ELECTRONIC SERVICE GUIDE IN DIGITAL BROADCASTING SYSTEM
First Claim
1. A method for transmitting an Electronic Service Guide (ESG) in a digital broadcasting system, the method comprising the steps of:
- collecting ESG data to be transmitted;
setting a number of Internet protocol (IP) streams to transmit the ESG data in order to transmit the ESG data in a multi-stream mode;
generating partitioning information used for each of the IP streams, the partitioning information including at least one partitioning rule to partition the ESG data into the IP streams and at least one partitioning value for the at least one partitioning rule, in which the at least one partitioning rule includes at least one among a service ID, a service genre, an absolute time, a session type, and a profiling type defined by a provider, and the at least one partitioning value includes at least one of a start value and an end value according to the at least one partitioning rule; and
transmitting the ESG data, which has been partitioned according to the partitioning information, through the IP streams.
