    • Disclosed is a system and a method for transmitting/receiving update information of Electronic Service Guide (ESG) data in a Digital Video Broadcasting-Handheld (DVB-H) system. For this, the system for transmitting/receiving the update information includes a DVB-H system for detecting the version of the ESG data which is to be transmitted, for inserting the version information of the ESG data in a predetermined table among tables containing Program Specific Information/Service Information (PSI/SI) data, and for transmitting the version information of the ESG data included in the predetermined table; and a DVB-H receiving terminal for receiving PSI/SI data and then analyzing the received PSI/SI data to detect the version of the ESG data from the analyzed PSI/SI data, for comparing the detected version of the ESG data with version information of ESG data detected from PSI/SI, which has been already received, in order to check if the two versions accord with each other, and for making connection with a transmission channel of the ESG data if the two versions do not accord with each other, to receive the ESG data, and then to update the received ESG data.

    • Disclosed is a DMB data receiving apparatus and method for improving a DMB data receiving speed. According to the DMB data receiving apparatus and method, if there are predetermined MSC data, which have not been received or received with an error when receiving MSC data by a DMB reception terminal, the DMB reception terminal can receive the predetermined MSC data through a return channel established between the DMB reception terminal and a broadcasting station. In detail, if there are predetermined MSC data, which have not been received or received with an error, the DMB reception terminal request the broadcasting station to transmit the predetermined MSC data and to allow establishment of a return channel, and then receives the predetermined MSC data through a return channel established based on the request. Therefore, when some MOT content data have not been received or received with an error, the DMB reception terminal can immediately receive the corresponding MOT content data without waiting until the next MOT data transmission period begins, thereby greatly improving the DMB data receiving speed.
    • 公开了一种用于提高DMB数据接收速度的DMB数据接收装置和方法。 根据DMB数据接收装置和方法,如果存在由DMB接收终端接收到MSC数据时没有接收到或接收错误的预定MSC数据,则DMB接收终端可以通过返回来接收预定的MSC数据 在DMB接收终端和广播电台之间建立通道。 详细地说,如果没有接收到错误的预定MSC数据,DMB接收终端请求广播电台发送预定的MSC数据并允许建立返回信道,然后接收预定的MSC 通过根据请求建立的返回信道的数据。 因此,当一些MOT内容数据没有被接收或接收到错误时,DMB接收终端可以立即接收对应的MOT内容数据,而不等待直到下一个MOT数据传输周期开始,从而大大提高DMB数据接收速度。
