    • Disclosed is a broadcasting system and method for transmitting/receiving a broadcast data in a broadcasting system, which reduces an application download period by efficiently utilizing a data broadcasting stream and a return channel for application download when a reception terminal receives a data broadcast. The broadcasting system and method includes a data broadcast reception terminal to receive the broadcast data and a bi-directional broadcasting server to communicate with the data broadcast reception terminal through a return channel: the data broadcast reception terminal receives a data broadcast stream during one broadcast transmission period, and requests the bi-directional broadcasting server to transmit a portion of the data broadcast stream (e.g. section data) through the return channel when the section data of the received data broadcast stream is lost; the bi-directional broadcasting server transmits the section data to the data broadcast reception terminal when a download request is received for the section data from the data broadcast reception terminal; and the data broadcast reception terminal performs modularization using a received lost section data and the previously-received section data to extract application files when receiving the lost section data and displays the extracted application files on a screen.
    • 公开了一种在广播系统中发送/接收广播数据的广播系统和方法,当接收终端接收到数据广播时,通过有效利用数据广播流和应用下载的返回信道来减少应用下载周期。 广播系统和方法包括:接收广播数据的数据广播接收终端和通过返回信道与数据广播接收终端通信的双向广播服务器:数据广播接收终端在一个广播传输期间接收数据广播流 并且当所接收的数据广播流的段数据丢失时,请求双向广播服务器通过返回信道发送数据广播流的一部分(例如,段数据); 双向广播服务器当从数据广播接收终端接收到针对分段数据的下载请求时,将该部分数据发送到数据广播接收终端; 并且数据广播接收终端使用接收到的丢失部分数据和先前接收的部分数据进行模块化,以在接收丢失部分数据时提取应用文件,并将所提取的应用文件显示在屏幕上。

    • A terrestrial DMB receiver using an imaginary channel in a terrestrial DMB system is disclosed. The terrestrial DMB receiver includes: a key input unit for receiving an input from a user; a display unit for providing image output to the user; an imaginary channel storage unit for storing information on imaginary channels designated to each broadcasting service by the user; a DMB receiving unit for receiving terrestrial DMB broadcasting; a MCI/SI analyzer for analyzing MCI and SI of FIC information from a DMB broadcasting signal received through the DMB receiving unit; and a controller for searching for the imaginary channel storage unit according to values of number keys input from the key input unit, extracting service IDs, controlling the DMB receiving unit to select broadcasting services according to the extracted service IDs, checking the information analyzed through the MCI/SI analyzer, and performing an update for the imaginary channel storage unit.
