    • Disclosed is an apparatus and method for transmitting/receiving an EPG when a digital broadcasting system uses different frequency channels according to broadcasters. In the apparatus and method, the digital broadcasting system determines a first frequency channel for transmitting first EPG data for all broadcasting programs, transmits the first EPG data through the first frequency channel at a first data rate, and transmits second EPG data through second frequency channels at a second data rate less than the first data rate, the second EPG data including both broadcasting streams of a corresponding frequency channel and at least part of the first EPG data. A receiving terminal receives the first EPG data through the first frequency channel, or receives broadcasting program data through one of the second frequency channels and simultaneously receives the second EPG data to updates the first EPG data.
    • 公开了一种当数字广播系统根据广播机构使用不同的频道时发送/接收EPG的装置和方法。 在该装置和方法中,数字广播系统确定用于发送所有广播节目的第一EPG数据的第一频道,以第一数据速率通过第一频道发送第一EPG数据,并通过第二频道发送第二EPG数据 在小于第一数据速率的第二数据速率下,第二EPG数据包括相应频道的两个广播流和第一EPG数据的至少一部分。 接收终端通过第一频道接收第一EPG数据,或者通过第二频道之一接收广播节目数据,同时接收第二EPG数据以更新第一EPG数据。
