Digital IP Webcasting
Digital IP network broadcasting is a purely digital one-way, two-way and multi-way audio reinforcement system based on IP data network, which transmits audio signals in packet form according to TCP\IP protocol on LAN or WAN, and then decoded by the terminal.
I. Advantageous features
1、Multiple broadcast partitions
Each webcast point in the IP network broadcasting system is an independent IP network node with its own independent IP address, and can form an independent broadcasting partition. Each webcast point can belong to multiple partitions at the same time. Changes to the partitions do not involve any physical changes.
2、Multiple programme channels
In the IP network broadcasting system, each broadcast programme is a set of IP data messages, and different broadcast programmes can be propagated in a network cable at the same time without affecting each other. 128KBPS of bandwidth is occupied by CD quality audio files, and when broadcasting 100 different CD-quality programmes at the same time, the bandwidth occupied by them is only 13M, which is less than 15% of a 100M LAN.
3、Multiple sub-control sites
All computers on the IP LAN can be used as sub-control stations to manage or use the CEOPAIP network broadcasting system.
4、Fast system construction
In places where there is an IP network, IP network broadcasting terminal equipment can be connected; in places where there is no IP network, it is relatively quick to build a simple IP network.
5、Good broadcasting sound quality
The IP network broadcasting system adopts an all-digital transmission method, which is not affected by the transmission distance or the environment, so listeners can enjoy the high-fidelity sound quality.
6、Saving system maintenance
IP network broadcasting system equipment is simple, network broadcasting terminal equipment using embedded systems cured in the processor chip, not subject to virus, can provide remote maintenance, saving a lot of maintenance work.
7、Easy system management
The system administrator is able to set up regular broadcasting tasks for different users and different partitions in advance, and the system will be executed automatically when it arrives, which is truly unattended.
8、Easy to use broadcasting
As long as the user of the broadcasting system obtains the authorization of the system administrator, he can execute the programme broadcast to the designated area on the computer sub-control station used by himself, or he can set up his own timing task to broadcast automatically, without running around for help.
II. Advantages of digital IP network broadcasting system compared with traditional broadcasting
1、The problems of traditional broadcasting system
Backward technology, poor compatibility and scalability.
Traditional broadcasting basically adopts the working mode of analogue transmission and manual management, the system is vulnerable to environmental interference and prone to crosstalk when broadcasting in multiple channels. Unable to achieve direct playback of digital format (MP3) audio files at the terminal, and unable to connect with IP networks to truly achieve digitalisation of audio sources and automation of playback management.
Poor sound quality and single function.
Broadcast equipment can only be used for background music and broadcast announcements and other activities within the area, and cannot meet the needs of remote unified broadcasting in the plant, or enable the company's management to address all plants at the same time.
Complex installation, inconvenient maintenance and high failure rate.
As fixed-voltage wired broadcasting is configured in strict accordance with the principle of matching impedance and power, the amplifier is often burnt out due to the failure of one transformer or speaker, affecting the entire broadcast.
Poor manageability and inability to be remotely controlled.
As only special playback equipment (tapes, records, CD players, etc.) and computers with stored MP3 files can be used as audio sources, dedicated personnel are required to manage broadcast content at special locations, so modern technology cannot be used to effectively manage broadcast audio sources, and remote playback control is not possible, which is not conducive to the flexible application of the broadcast system and causes waste of resources.
2、Advantages of digital IP network broadcasting system
Stronger functionality.
The pure digital broadcasting system covers all the functions of the traditional broadcasting system. It also makes full use of WAN resources and can access audio resources on the network anytime and anywhere. As each terminal has an independent IP address, it can therefore control any terminal to broadcast different programmes
Better sound quality.
No transmission interference and distortion of the audio signal due to the network transmission technology. The MP3 compression algorithm uses low network bandwidth (8k-128k) and ensures sound quality fidelity, tested at 44.1khz16bit sampling 128kbps rate compression passband (line output) 20-16khz, distortion ≤3%
Simpler installation.
Simple installation. Provided that each plant has the following 2 conditions: (1) ADSL dial-up Internet access; (2) AC 220V socket and standard Ethernet access RJ45 socket.
III. System functions
1、Grouping control: All network terminals can be broadcast in any group, which greatly enhances the flexibility of terminal management.
2、Real-time task: Real-time broadcasting and real-time picking and broadcasting can be realized; the contents of the computer media library and the real-time picking and playing of external audio sources can be played anytime and anywhere.
3、Timed ringing: respond to ringing needs at specific times and specific places, and a variety of ringing schemes can be customised.
4、Timed picking and playing: specific peripheral audio sources are collected and played to a specified area at a specific time, and the system provides a peripheral control interface.
5、On-demand function: remote media library files can be realized on-demand, and operations such as play, pause, fast forward, fast rewind, previous song, next song, etc. can be performed.
6、Intercom function: two-way intercom can be realized between broadcasting terminals, with full duplex working mode.
7、Fire linkage: the system can be seamlessly connected with the fire alarm system to achieve broadcast fire alarm.
8、Casting recording: Real-time recording of broadcast content can be realized and used as audio data for preservation.
