As the name suggests, digital network broadcasting is a broadcasting system that digitizes (A/D-converted) broadcast signals and transmits them over Ethernet (TCP/IP) or the Internet (Internet). That is, after the analog audio signals are collected, quantized, and encoded, according to the network. A broadcast method in which a protocol transmits over a network.
2. What is the principle of digital network broadcasting based on, and what is the reliability?
Digital network broadcasting is to collect compressed digital audio files (such as MP3) or digital audio files stored in the memory in real time according to a certain algorithm, and transmit the audio files to the network broadcast receiving end in the form of data packets according to the transmission protocol through the network. Then, after the D/A conversion by the network broadcast terminal, the audio signal is restored, and after being amplified, the speaker is driven to work. Each network broadcast terminal is an embedded computer with audio codec and network communication functions, and has its own independent IP address. Like the PC network in the LAN, it communicates according to the TCP/IP protocol.
3. What are the components of digital network broadcasting?
Network audio broadcasting is structured by a master computer (audio server), a set of broadcast software or server software, and the audio files are sent to the remote network terminal by IP flow. Each terminal should have a fixed IP address and network module, a professional digital audio decoding device (software or hardware), power amplifier control unit.
4. What is the sound quality of digital network broadcasting , will there be a delay?
Digital network broadcasting adopts MP3 audio compression format, sampling frequency 44.1KHz, 16Bit high-quality audio compression format, and adopts pure digital transmission mode, which does not generate noise accumulation during production, processing and transmission, causing signal-to-noise ratio The drop causes the signal to deteriorate.
In theory, digital network broadcasting has a delay in transmission remote transmission. It takes a certain time for transmission-cache-decoding. However, as long as the downlink bandwidth of the network is 128K, the stereo audio signal can be transmitted very smoothly. It can be controlled within 0.3 to 0.5 seconds, and it does not affect from the point of view of use.
5. What are the technical advantages of digital network broadcasting compared to traditional broadcasting?
Digital network broadcasting is a truly digital broadcasting system in its true sense. The digital format is completely used for the production, storage and transmission of program sources. Traditional broadcasting (constant-pressure broadcasting, FM broadcasting) is generally only digital in recording and broadcasting, but analog transmission is still used in the transmission process, so the sound quality of digital broadcasting should be superior to traditional broadcasting.
6. How many broadcast signals can a digital network broadcast transmit at the same time?
Because digital network broadcasting is pure digital signal transmission, it is not limited by the number of programs. It can broadcast different programs to each network broadcasting terminal. It is no problem to transmit dozens or even hundreds of signals simultaneously in actual use. , fully meet the requirements of regular broadcasting.
7. What is the wiring structure of digital network broadcasting , and how far can it be transmitted?
Digital network broadcasting is designed according to the technical standards of the most common Ethernet transmission architecture. As long as there is a network interface, network broadcasting terminals can be installed without special wiring, whether it is optical fiber, super five cable, digital microwave or wireless network. Bridges can transmit network audio broadcasts as long as the network is connected.
8. Can digital network broadcasting implement AOD on demand?
It is ok, because the network broadcast itself works under the TCP/IP protocol based on two-way communication. The two-way broadcast terminal of stellar science and the network power amplifier with on-demand function can query the server for remote on-demand or scheduled play through the remote controller.
9. Can digital network broadcasting achieve two-way intercom function?
It can be said that the network broadcast is two-way communication. The stellar Coton HX network broadcast terminal is embedded with the microphone and voice acquisition transmission module, which can fully realize the intercom function with the broadcast center.
10. Should digital network broadcasting be transmitted over the wide area network (Internet)?
Yes, each terminal of the digital network broadcast has its own fixed independent IP and server to communicate, but in the wide area network, the telecom operator assigns each user a dynamic IP, so that the network broadcast terminal cannot be combined with the wide area network. Direct server communication, Stellar Coton uses IP resolution technology, can set up a VNN server specifically, as a relay in the communication, that is, when the network broadcast terminal and the broadcast server work on the Internet, they first access the VNN after startup. The server reports its own IP address and ID to the VNN server, and then the VNN server directs the IP of each terminal to the broadcast server to establish two-way communication, thereby completing the network broadcast on the wide area network.
11. Can digital webcasts be broadcast live?
Yes, the network broadcast can be collected, quantized, and encoded in real time through the LININE port of the sound card, and the live broadcast function can be realized. 1. What is digital webcasting?
As the name suggests, digital network broadcasting is a broadcasting system that digitizes (A/D-converted) broadcast signals and transmits them over Ethernet (TCP/IP) or the Internet (Internet).
