Abstract

The invention discloses an addressable teaching broadcast system, consisting of a multimedia computer, a sound source, a digital encoder, an intelligent broadcast decoder, a sound box and an automatic fault off-line circuit, wherein, a broadcast system software is arranged in the multimedia computer and connected with the digital encoder, an input end of the digital encoder is connected with an output end of the sound source, the output end of the digital encoder is connected with the input end of the intelligent broadcast decoder, and the output end of the intelligent broadcast decoder is connected with the sound box which restores a signal from the sound source into a sound. The automatic fault off-line circuit is connected with the intelligent broadcast decoder to prevent partial failure and guarantee normal broadcast of the broadcast system. The system changes the traditional form of the school broadcast in the past and has the advantages of simple and reliable structure, flexible and practical configuration, humanized operation, high quality, economy, stability, and practicality, etc.

Description

technical field [0001] The invention belongs to a broadcasting system, and in particular relates to an addressable teaching broadcasting system. Background technique [0002] The broadcasting system is one of the indispensable infrastructures of every school. Despite the rapid development of video technology and network technology in recent years, the broadcasting system is still used by various schools because of its practicability, economy and convenience. All kinds of schools in our country basically have public broadcasting systems, which are mainly used in various public occasions, such as holding school-wide activities, announcements, raising the national flag, inter-class exercises, broadcasting inter-class music, commending advanced, and holding school-wide meetings Wait. Limited by resource conditions, network broadcasting (communication protocol is TCP / IP mode) has real-time delay, complex technology, large investment, and difficult maintenance. All classrooms br...
