"Villages" new rural integrated IP broadcast solutions

Background

1,2006, the State Council issued a document on the 1st, a new socialist countryside construction. All levels of government continue to implement the radio and television, "every village" project.

2,2005, 2006, SARFT full deployment of the "village" project, requiring "five included": Central clear requirements should be included radio and television coverage of party committees at all levels of government work agenda to include Government economic and social development of socialist new countryside construction master plan at all levels, at all levels of public expenditure into the government budget, incorporating all levels of government poverty alleviation program, the assessment of cadres into the content.

3, SARFT on the issuance of "" Eleventh Five-Year "period of radio and television technology development plan," the notice (2006.12.21), and has published DAB national industry standards ("30MHz-3000MHz Terrestrial Digital Audio Broadcasting System Technical Specifications", 2006.5. 19) vigorously promote digital broadcasting.

The role of the "village" New Countryside IP broadcast

1, IP network broadcasting system in the county rural radio, suitable for providing a wealth of professional science, education, law, journalism and cultural knowledge to the township (town) or village. Effectively improve the technological content of the modern countryside. Make from village to village, village and county, village and city in close connection with the broadcast to enhance scientific and technological development in rural areas.

2, to achieve levels of radio stations up and down the network interconnection. In the municipal center, allowing access to authorized provincial departments. Levels can be controlled down by superiors authorized to access upwards.

3 levels (city / district / county and township / street) broadcasting station can provide multiple modes of access. Including telephone (landline, mobile, IP telephony), IP microphone, broadcasting stations mining software, remote access, and CD, radio (AM / FM / DAB), microphones and other analog audio local access. Output to lower radio stations, but also through the network to the front output AM / FM / DAB radio.

4, the end of the broadcast station (village, neighborhood) in addition to access to higher broadcasting, can access local analog audio. After the amplifier output driver tweeter / frets, or FM modulated output to the speakers.

"Villages" new rural IP broadcast design ideas

1, the network structure and transmission technology, in line with trends, both economic costs and practicality. "Network + Radio" double coverage, "Wired + Wireless" combinations.

2, the value to the party and government cultural propaganda, public emergency command driven, supplemented by e-government (notices, meetings, hotlines), government communications and rural public entertainment and other functions.

3, self-contained broadcasting network, hierarchical access control. Under the premise of safety broadcast, governments at all levels to facilitate telephone, computer networks and other forms of access, to achieve commercials, broadcast and other functions.

4, stable and reliable, high quality, easy to use, simple to maintain. Front-end IP handset, using the IP broadcast midway switches, two-way IP voice terminal ends.

Advantage "villages" new rural IP broadcast

Powerful

Pure digital radio system that covers all the features of traditional broadcasting system. And the implementation of the audio-on-demand function. And make full use of network resources, audio resources available on the network at any time. Since each terminal has a separate IP address, which can control the playback of any type of a terminal program

CD quality sound

As a result of network transmission technology to transmit audio signals without interference and distortion. MP3 compression algorithm uses network bandwidth low (8k-128k) but also to ensure fidelity sound, tested using 44.1khz 16bit sampling rate 128kbps compression pass band (line-out) 20-16khz, Distortion ≤ 3%

High reliability

Instability of traditional broadcasting system depends on the quality of the main transmission lines, transmission lines or unreasonable cause instability and even burned constant pressure power amplifier. Since pure digital broadcasting system by means of sophisticated Ethernet communications technology, each terminal device is equivalent to a simple computer linked into the local area network. Users only need to ensure the smooth flow of the network, without adding additional maintenance.

Simple installation

Installation is simple. Just have the following three conditions: a 220V AC outlet, have a standard Ethernet access socket (RJ45) and a location placed under digital broadcasting terminal (one speaker volume).

"Villages" new rural IP broadcast function

Covers all the features of traditional broadcasting system

Including business speech radio, background music, regularly rang the bell and radio programs broadcast and so on.

Systems based on IP network, follow the TCP / IP protocol

Multi-line, full use of the computer network resources, avoid duplication of overhead wire, an Ethernet interface, where you can take a digital broadcast terminals, real radio, computer networks, multi-play.

Leading online speech

Leading online via any computer, connected to a microphone, which can achieve radio address, broadcast or you can specify all local broadcasting, remote support via Internet broadcast. Issued an emergency broadcast notification.

Real-time interviewing

The external audio (deck, CD, radio, microphone, etc.) audio server real-time access to high-quality compressed data stream, and broadcast data sent over the network, real-time digital broadcasting receiving terminal and play through the built-in speakers. Provides a wealth of professional science, education, law, journalism and cultural knowledge.

Regular broadcasts

Digital broadcasting terminals with separate IP addresses, the server can receive personalized regularly broadcast programs alone. Audio material storage announcer will need to use on the server's hard drive, and prepare to play program, mission planning system will be fully automated broadcast.

Multiple partitions broadcasting

The system can be set to any number of groups playing audio programs developed by or for any specified area radio address; service software can remotely control the playback contents of each terminal (delineated area play), etc. and volume;

Emergency fire radio (optional)

Fire alarm systems can access the signal, fire linkage and support neighborhood level alarm.

Terminal built-in switch (optional)

Switching a digital broadcast terminal built 100Mcard module, the terminal can solve the problem of the port occupied by the existing network, but also an appropriate one to two terminals connected in series, the investment saving wiring.

Audio material production

Digital material can clip, mixing, fade, noise elimination, variable speed constant adjustment and other functions.

System resources than the server can store thousands of hours of music programs or voice programs. Users can expand the storage space or replace the server, or adding disk arrays and other equipment to enhance the system performance based on the actual situation.
