Analysis Modern layout of the multimedia classroom gear requirements more and much more, including Projector , Electric screen, personal computer, video show stand, audio and so on. In order that the operation of complex multimedia devices grow to be simplified, intelligent, common practice is to use existing multimedia Central control Method (the manage) to connect these devices, controlled by the centralized manage, for example, teachers can effortlessly switch the microphone input or play personal computer audio information can be accomplished via the manage system of each and every classroom multimedia gear, remote monitoring and management. Of course, such a network to the classroom to facilitate the provision of other applications for open space.
In addition, Campus radio Is crucial in schools in the globe. Standard analog set up specific campus radio broadcast channel, will broadcast the signal to introduce classroom, into the power amplifier energy amplifier, and then into Speaker Play. This broadcasting method delay is little, a great number of terminals simultaneously. However, it utilizes low frequency, significantly less susceptible to interference require to set up specialized radio circuits, higher expense, influence on campus appearance, system expansion and poor challenging to attain higher-fidelity audio signals.
Classic classroom need to have to install two systems: the handle method, connect a assortment of multimedia gear broadcasting technique, like the audio decoder, amplifier, speakers. The two systems are independent of each other, can not be linked, if you want to control the technique in the broadcasting system for audio output and switch in between the audio output, you require to manually re-amplified to change the wiring. This drastically increased the difficulty of teaching employees in the operation, but also increase the management and upkeep much more challenging. In addition, the audio decoder and the controller requires its personal distribution network, IP address, also led to a waste of network resources.
Analog broadcasting in order to resolve these troubles, using TCP / IP network Technologies The audio signal to form IP packet protocol for transmission on the network technology has been created. iDste embedded multimedia, broadcasting integrated intelligent control program is to use TCP / IP network technologies to MP3 format audio data stream sent out, and then receives a specific decoding device, decoding device and then to the MP3 audio stream into audio decode signal, and then sent to power amplifier power amplifier, and then into sound box.
IDste embedded multimedia, radio integration control?? To bring fresh and sensible impact of the user
[HC Education Network with plans] [HC Education Network with plans] IDste embedded networked multimedia, radio, control integration is an integrated digital broadcasting in the control method. The method can be directly received from the network to decode the audio stream and then restore the speech signal, so no longer need to have a unique decoder. This not only removed a specific audio decoder, minimize costs, will also broadcast the signal connected to the central handle system, to the broadcast signal only as an audio input in the handle of the impact of enabling broadcasters and other audio input linkage to facilitate the switch. Because all of the audio input through the handle of centralized control and then enter, amplifiers also can be fixed then in manage of the audio output on the. As in the combined control method and broadcasting system, you can use the very same system to manage all the gear, monitoring and upkeep, which also reduces the campus facilities management and monitoring difficult, greatly reducing maintenance expenses. Compared to analog broadcasting, the integration of digital broadcasting has excellent scalability, can be arbitrarily extended to the campus exactly where any IP network.
For compatibility with conventional analog broadcasting, iDste multimedia, broadcast integration control method also enables direct access to analog broadcast signals in the control, in order to achieve analog broadcasting and other input to the manage of the audio interaction capabilities. This guarantees that the school’s investment in conventional analog broadcasts, the college also the function of the analog broadcast an emergency backup gear to use in order to net the case of paralysis can still use the radio.
