Embodiment Construction

[0023] refer to figure 1 , Indicates the flow chart of single-channel courseware collection and compression transmission and the description of its equipment configuration. The audio signal sent by the camera equipment forms digital audio signals of different formats after passing through the audio analog-to-digital converter and audio encoder; The video signals sent by the equipment are converted into digital video signals of different formats after being passed through an analog video decoder, a video preprocessing filter and a video encoder. They are sent to a digital signal processor for packetization to form a composite stream. Send the system stream to the modulator to form a modulated signal conforming to the specific channel characteristics and send it to the corresponding channel for transmission (such as Ethernet, etc.).

[0024] refer to figure 2 , indicating the schematic diagram of multi-channel receiving and streaming equipment, indicating that the signal rece...

Abstract

A remote mirroring education system based on broadband network for school is disclosed, which includes such steps as manually transmitting the education contents to computer room by magnetic tape or audio-video transmission, compressing and streaming the education contents by multi-hannel or single-channel equipment, receiving modulated signal, demodulating, multi-channel receiving and streaming, and storing them to VOD server.

Description

(1) Technical field [0001] The invention belongs to the field of broadband network applications, and in particular relates to the establishment of a school remote image education system based on a broadband network in realizing distance education. (2) Technical background [0002] Education is the foundation of a nation's prosperity. Therefore, focusing on education and cultivating talents has always been the top priority of the party and the country. The cultivation of the quality of a generation of talents must start from the primary, junior high and even earlier stages. Our country The establishment of a considerable number of key universities, key middle schools and primary schools also aims to set an example and model, and drive more schools and students to follow suit and develop. After all, there are only a small number of students who can enter key schools; more students who cannot enter key schools are eager to receive the same education as key schools, which depend...
