Abstract

The invention relates to a multimode emergency broadcast terminal with FM-CDR receiving. Comprising an FM-CDR receiving module, an FM-RDS receiving module, a DVB-C receiving module, a DTMB receiving module, a DVB-S receiving module, a digital medium wave receiving module, an IP network module, a CDR data buffer area, an RDS data buffer area, a DVB-C transport stream buffer area, a DTMB transport stream buffer area, a DVB-S transport stream buffer area, a digital medium wave data buffer area, an IP network data buffer area, an extraction module, a message processing module and a security module. The system comprises a storage module, a playing content processing module, a digital audio and video output module, a digital-to-analog conversion module, an audio switching module, an analog audio output module and an audio acquisition module. Signal channels such as FM-CDR are supported to receive emergency broadcast messages at the same time, and the channel anti-disaster performance of the terminal is improved.

Description

technical field [0001] The invention belongs to the technical field of emergency broadcasting, and in particular relates to a multi-mode emergency broadcasting terminal including FM-CDR reception. Background technique [0002] The emergency broadcast system consists of an emergency broadcast platform, an adapter, a transmission coverage system, and an emergency broadcast terminal. The emergency broadcast platform transmits emergency broadcast messages to the emergency broadcast terminal through the adapter and the transmission coverage system for playback. The emergency broadcast message includes emergency broadcast instructions and emergency broadcast content. The emergency broadcast content is the supplementary content of the message (text, audio, audio and video) or the parameters of the specified broadcast and TV programs. [0003] The emergency broadcast terminal is an integral part of the emergency broadcast system and the key to solving the "last mile" of emergency b...
