Information broadcasting network access device

Abstract

The invention discloses an information broadcasting network access terminal device comprising an analog-to-digital converter circuit, a first address latch circuit, a main controller, a second addresslatch circuit, an external static data memory circuit, a network controller circuit, a network transformer circuit and a data interface circuit, wherein the analog-to-digital converter circuit, the first address latch circuit and the main controller are connected in sequence; one end of the second address latch circuit is connected with the main controller, and the end of the second address latchcircuit is connected with the external static data memory circuit; the other end of the external static data memory circuit is connected with the network controller circuit; the network controller circuit is connected with the network transformer circuit; and the network transformer circuit is connected with the data interface circuit. The information broadcasting network access terminal device can stable network access of campus broadcast, so that the campus broadcast can fully use the network resources, and realize the function of audio on demand, and is stable and reliable.

Description

technical field [0001] The invention relates to the field of information broadcasting, in particular to an information broadcasting network access terminal device. Background technique [0002] There are many types of communications and broadcast network infrastructure. During the development of broadcasting and communication, broadcasting is divided into ground wave and satellite broadcasting; communication is divided into various forms of network systems such as Internet, mobile communication, and public switched telephone network communication. For ordinary users, Internet service providers and commercial computers receive Internet services and video-on-demand broadcast services. Campus broadcasting is a kind of low-power FM broadcasting. Many colleges, middle schools and even primary schools have now adopted a large number of campus FM broadcasting to broadcast English programs or other programs. The frequency range is usually between 76-87MHz. The TV with sound radio ...
