Problems solved by technology

[0011] However, in the case where the terminal of the service purchaser is not connected to the broadcast service when the notification message is transmitted via the broadcast channel, the terminal cannot receive the notification message
Therefore, in order to receive every unexpected notification message, the terminal should always stay connected to the broadcast service, although this is inefficient

Abstract

An apparatus and method for transmitting / receiving a notification message in a Digital Video Broadcasting (DVB) system are provided, in which a terminal detects an Access Point (AP) from an Electronic Service Guide (ESG) bootstrapping session, queries the AP to request a notification message list or all or part of a notification message over a communication channel, and receives the notification message list or all or part of the notification message from the AP.

Description

technical field [0001] The present invention relates to an apparatus and method for transmitting / receiving notification messages in a Digital Video Broadcasting (DVB) system. More particularly, the present invention relates to an apparatus and method for transmitting / receiving a notification message via a communication channel in a DVB system. Background technique [0002] Digital Video Broadcasting (DVB) is a European digital broadcasting technology and supports a transmission standard for providing digital multimedia services as well as legacy digital broadcasting services through mobile or portable devices. [0003] The DVB system can multiplex broadcast data based on Moving Picture Experts Group-2 (MPEG2) Transport Stream (TS) and simultaneously transmit an Internet Protocol (IP) based data stream. The DVB system can also send multiplexed data from multiple services in one IP stream. Accordingly, a terminal supporting the DVB system receives an IP stream, demultiplexes...
