1) Intelligent air conditioning and projection equipment management system

     With the development of the economy and the improvement of material conditions, the school has become one of the most concentrated public areas for air-conditioning. How to effectively manage the air-conditioning in separate classrooms and other office areas, this is to build a low-carbon green campus. One of the primary goals. iDste uses a highly innovative means to intelligently manage and control classroom split air conditioners by means of wireless terminals that have been distributed in classrooms. Managers only need to input task modes according to preset time intervals. The class air conditioner can be turned on and off according to the preset mode (first turn the power on and off after the machine is turned on to ensure the air conditioner specification is used). Saving energy does not affect the terminal's actions performed according to any preset tasks.

The following main functions can be intelligently implemented through the platform software:

■ Remote monitoring, management intelligent central control and setting intelligent central control operation

■ Develop an implementation strategy for intelligent central control (including switching, power-off, identity verification, etc.)

■ Visualize the usage of the device

■ Remote configuration of intelligent control parameters

2) Digital IP Broadcast Support System

Although digital IP broadcasting provides a very easy means and free imagination for audio transmission, efforts should be made to cater to the actual application of the user, and it is necessary to work hard on software functions and performance. The integrated software system of iDste digital IP broadcasting should be perfected by the actual operation requirements of the first-line teachers on campus. It has become one of the best digital broadcasting management and broadcast software systems for campus. Relying on a strong R & D team and extensive research. The software system of iDste digital broadcasting starts from the user's actual situation and grows together with the user's needs. At present, the main functions such as automatic or manual intelligent broadcast, mode setting, mobile call, and role login based on various complex environments have been completed. The realization of these functions has greatly exerted the application characteristics of campus digital broadcasting. Since the software system is oriented to the needs and development of digital signals on campus, this greatly enriches the needs of front-line users, and it is very pragmatic to reduce the users of first-line users. Work pressure.

■ Intelligent broadcast

     The broadcast system of iDste digital broadcasting system takes the timeline as the main axis, which fully meets the characteristics of time regularity, punctuality rate and signal standardization of campus digital broadcasting. For the signal setting of one semester, the user only needs to set it once in the software, and the whole semester will take effect. At the same time, the software also provides a very user-friendly setting means, which is convenient for the user to manually select the real-time manual broadcast. The function settings of each playout task provide very detailed parameters for the user to choose, such as: broadcast time, duration, volume, source, temporary or normal, random selection, and so on. These rich parameter settings almost meet all the broadcast conditions of campus audio broadcasting, providing users with extremely convenient practicality and strong intelligence.

■ Mode setting

The extremely complex campus ring signal system operates intelligently according to specific logic. This is the challenge faced by all digital IP broadcast system software platforms. The mode setting in the iDste software system provides innovative operation for the system. Means, the perfection and application of this function, provides a very simple means for complex signal setup on campus. For example, a very frequent simulation test in the third grade, which requires a specific ringtone for the third grade exam. Use the mode function to match the level setting of the iDste convention. Operators can easily handle this task in a "mode" manner without having to change tasks frequently. After the end of the mode time of the grade stage, it is automatically changed to the normal timing "mode". All the prescribed signals will be delivered to each classroom in accordance with the "mode" requirements and accurate. There is no limit to the number of “modes”. From “exam mode” to “summer/winter mode”, in order to cope with the increasing number of holidays, iDste can set the user-friendly settings in software functions. care.

■ Mobile call and role login 

PC BC.png

iDste provides mobile call and automatic playout system based on TCP/IP network. The biggest feature of this system is to integrate the computer terminals on the existing campus network with digital IP broadcast through specific protocols, so that all the broadcast needs of the campus can be used. Those who can directly participate in the setting of the digital broadcasting system through their own desktop terminals, the open functions are reflected in the information means for everyone. These do not require proprietary equipment to participate in the functions of digital broadcasting on campus, and bring a very easy-to-use experience to grade groups, classroom teachers (especially English teachers), general affairs, and academic affairs. Each user participates in the organization's broadcast function under a specific authorization based on a specific authorization. For example, a high-level third-grade English teacher with four classes can use his administrator's authorization and time grouping restrictions every day. He can organize the English listening broadcast at the next morning of the day, and set it up in the second. The day server will automatically broadcast his playlist content to a specific group, without any other manual intervention. Of course, he can make a voice call to the relevant group (group member) within the allowed permissions. iDste writes specific authorization information into the authorization information of the portable USB-Key. The iDste digital audio broadcasting station solves professional problems from the perspective of proprietary devices, such as the network broadcast of campus radio stations. Real-time acquisition of analog sound sources and broadcast on digital networks. The iDset digital broadcasting system, from both the software and the hardware, constructs, organizes and implements the entire system with open thinking, truly bringing the application to the ground and catering to the actual needs in the most convenient way.


3) High-definition audio and video direct broadcast

    Media such as media resources (supporting 1920*1080P) and text information in the media library are broadcasted to the grouped audio and video terminals according to a predetermined time. Level and time limits can be set for all media broadcast tasks.

    Relying on the TCP/IP network, the live real-time scenes are point-to-point and point-to-group in full HD format to the audio and video playback terminal, time-on-demand Internet or LAN video resources, and single-point or packet-to-broadcast to any audio and video playback terminal in the LAN. Support for HTTP on-demand protocol.

4) Equipment management

    All audio and video playback terminals can perform pre-mode setting and remote management, and can automatically cut or select strong cuts for audio and video broadcasts from the server, and automatically activate or deactivate the connected display devices when unattended ( Such as projectors, LCD terminals, stereos, etc.)

5) Media Management

    Powerful database support, fast uploading means, single or batch upload audio and high-definition video files, audio and video playback supports MP3, MOV, AVI, TS stream and other mainstream formats.

6) Role management of multi-service integration

    Support all functions of iDste digital IP broadcasting. Only one iDste NC-02 terminal device is needed inside the platform. With iDste fusion platform support software, it can realize multi-services such as centralized control of equipment, digital IP broadcasting, high-definition video decoding, and campus cultural information release. Combine multiple campus utility functions to truly reduce the repetitive investment of equipment. Each type of business management is managed by a specific role.

                      

Third, the application scenario of iDste integrated multi-service system

    The iDste fusion system is based on the intelligent management terminal equipment (iDste NC-02A) installed in the classroom. The terminal is connected to all the audio-visual equipment in a single classroom. Because it has intelligent management of the connected audio-visual equipment, it is provided by digital campus. With the data network interface of the classroom, combined with the iDste converged server and multi-service support platform software, we can build an intelligent, all-digital, high-definition intelligent broadcast and direct broadcast platform. The broadcast system utilizes the media management and support platform provided by the iDste fusion system. As long as the content to be broadcasted is pre-established, the intelligent broadcast can be scheduled and grouped in a preset manner. The smart terminal distributed in the classroom can automatically activate the connected display device, and the display device can be automatically turned off after the completion of the play, without any manual intervention. Utilizing the existing campus network without re-laying additional cables, the iDste support platform relies on proprietary proprietary protocols and provides strong cross-network configuration support. Since each terminal uses professional pure hardware full HD decoding, the broadcast quality is exceptionally good. For live broadcast or live TV broadcasts that are often encountered on campus, the iDste Convergence System also offers a powerful HD encoding device (iDste BW-802) that delivers high-definition signals from SDI/HDI, HDMI, CVBS to H.264. The format is output through the network, and the iDste support platform can push the timing of any code stream program from iDste BW-802 intelligently to any terminal device.

   The iDste converged multi-service system, which is integrated with high-definition video, has been applied to hundreds of primary and secondary schools in Shenzhen, Jiangsu, Fujian, Shandong, Beijing and other places, successfully achieving the broadcast and management of HDTV services on campus TV stations. With the continuous improvement of the system, a new concept of fully digital, intelligent integration of campus TV stations and campus culture intelligent broadcast and management system will have a profound impact on the future of smart campus.
