A. Network broadcasting server software
1. Can directly connect to the standard TCP/IP protocol network and utilize existing networks to achieve multi network integration;
2. Adopting embedded systems as the main architecture to avoid virus attacks on broadcasting hosts;
3. When the server in the main control room is disconnected, it does not affect the broadcasting use of each sub control room and partition;
4. Campus broadcasting software is the core of the campus audio broadcasting system, which completes the permission management function within the entire campus broadcasting, provides data interface services for the acquisition and broadcasting of various audio broadcasts, and provides timed playback and real-time media acquisition services to network broadcasting equipment in various regions, responding to playback requests from various broadcasting control equipment. After organizing and arranging the audio program menu, it can be transmitted to the system server through the campus network, and management personnel can log in and modify it through broadcast management software;
5. Automatically detect faulty network broadcasting equipment;
6. Equipped with an automatic control and manual operation platform with programming accuracy to the second;
7. Easy to operate and visually displayed. Real time display of the current working status of each network terminal, with human-machine dialogue function;
8. Supports uninterrupted working hours of 7 x 24 hours;
9. Super strong data processing capabilities, supporting multi-threaded data processing, and supporting multi-user online services;
10. Rich program sources, playback options for any set of programs, and independent control for each set of programs;
11. Powerful control function, controlling online network broadcasting terminals, capable of independent zoning, IP, volume control, and detecting the online status of the terminals;
12. Single point, partition free on-demand: The broadcast terminals distributed at each broadcast point can be controlled by the infrared remote control or buttons of the terminal device to complete any on-demand or channel selection of the database in the server. It can fast forward, fast rewind, pause, and repeat between two points AB. Terminals with LCD screens can display information such as database directory, volume size, IP address, and current playback location on the display screen;
13. The program can be programmed and controlled by week, month, day, etc;
14. Fully digital signal processing and transmission;
15. Session Heartbeat: Through the heartbeat mechanism between the service and the session client (also known as handshake, handshake every ten seconds to detect online status, automatic restart of terminal devices, fully intelligent), it avoids abnormal client exits and long-term occupation of the terminal by deadlocked sessions;
16. Equipped with built-in fire alarm function, it can achieve single point, single zone, multi zone, adjacent layer, N ± 1, N ± 2, N ± 3, N ± 4, N ± 5, and multiple alarm modes for the entire area. The expansion can provide a secondary development platform, connect with other systems, and support Internet transmission.
B. Management software (can be used for sub control)
1. Complete terminal management, task management, permission management and other management functions, and provide data mining interface services for various voice acquisition;
2. Provide system operation programming functions;
3. Real time monitoring of the operational status of various devices in the system;
4. Can remotely log in to the host based on user password permissions and effectively manage the host;
5. Capable of controlling devices in the system through software.
C. Broadcast/insertion software
1. Complete the live streaming function of leaders on various campuses online;
2. Speak directly through an office computer;
3. You can directly select and block playback areas online;
4. Complete network radio broadcasting, courseware resource conversion, and real-time audio broadcasting;
5. Convert various analog audio signals into digital signals;
6. Can live stream various external audio sources to various network audio terminals in real time;
D. Configure software
1. Device ID: A unique ID number assigned by the manufacturer to each device, which is used by the server to identify each device during system operation;
2. Device MAC address: Each network device has a globally unique network hardware address assigned by the manufacturer;
3. The IP address and port number of the device: The IP address of the device itself needs to be unique within its network segment. Most devices are located within a local area network, with an IP address of 192.168. x.x. Maintain default values at the factory and configure them on-site according to network management requirements. If there is no special need for the port number of the device, keep the firmware default value;
4. Gateway IP address: The LAN port address of the upper layer router on the subnet where the device is located. Subnet mask: usually 255.255.255.0;
5. Server IP address and port number: The server's own IP address and port number are set on the server, and the IP address is configured according to the network environment. If there is no system conflict, the port number should remain at its default value;
6. Corresponding server IP address and port number must be set on the network audio device, otherwise the device cannot connect to the server correctly. It should be noted that the settings on the device are related to the network environment, not necessarily the values displayed on the server, but rather the IP of the router on the local area network where the server is located;
7. Device Description: A string used only for viewing and does not affect device operation. Similar to Room X in the X teaching building of XX campus, it is for the convenience of equipment management.
