Abstract:
为了使用广播服务适当地传输紧急警报信息，具有100msec的传输帧间隔的前导码部分(31)包括调谐数据部分(31A)和保留位部分(31B)并且包括预定的总位长。在所述调谐数据部分(31A)内存储用于调谐至相关的接收侧广播信道的L1数据。而且，在所述前导码部分(31)内部的所述保留位部分(31B)内存储由紧急警报信息处理部分(202)处理的紧急警报信息。在预定义消息模式下，消息以二进制格式表示预定义紧急警报信息并且在仅仅一个帧内传输。
Abstract(English):

In order to suitably transmit emergency alert information using a broadcast system, a preamble part (31) that has a transmission frame interval of 100 msec includes a tuning data part (31A) and a reservation bit part (31B) and comprises a predetermined total bit-length. L1 data for tuning to a relevant reception-side broadcast channel is stored in the tuning data part (31A). Further, emergency alert information that is processed by an emergency alert information processing part (202) is stored in the reservation bit part (31B) inside the preamble part (31). In a predefined message mode, a message expresses predefined emergency alert information in binary format and is transmitted in just one frame.
