1. Realization of functions and features
â— Realization function:
For this solution, we use the sunflower TV broadcaster (AVCaster â„¢) and the multi-channel TV demodulator (TV2AV) to build a professional and stable campus network TV station and develop network TV in the campus network. It can realize 16 channels of network TV, which meets the purpose of the majority of teachers and students to watch TV through the network, view TV program videos and so on.
â— Characteristics of the program:
1. Professional grade equipment provides super stability;
2. The implementation is convenient and fast, and it is easy to carry out the live TV broadcast business;
3. Designed specifically for the characteristics of campus networks, it can achieve unicast and multicast to meet the concurrency of large-scale users;
4. Good expandability, according to the characteristics of the university's multi-campus, provide a proprietary solution, multiple campuses can share the same live broadcast source;
5. Extremely cost-effective, a package of campus network TV station solutions, only need to provide its own cable TV access port, network access port.
2. System composition and application structure diagram:
â— System composition:
1. User-supplied cable TV port and network access port;
2. One sunflower live TV broadcaster, model: AVCaster â„¢ -16;
3. One multi-channel TV demodulator, model: TV2AV-16;
â— Application structure diagram:

3. Brief introduction of realization function:
1. Support unicast and multicast modes, and can provide network TV services across routers and firewalls;
2. Support server cascading applications, backbone network unicast, local area network multicast, suitable for modern university multi-campus simultaneous development of network TV;
3. Support B / S and C / S two application modes, which can meet the purpose of personalized network TV on campus network;
4. Adopt pure hardware to realize the collection and compression of audio and video signals, which does not occupy system resources at all, has strong stability, and can meet 7 * 24 uninterrupted live broadcast;
5. Both AVCaster and TV2AV use shelf-grade industrial chassis, which has good stability and high integration, and the project implementation is convenient and fast;
6. Integrate many functions such as audio and video collection, compression, storage, publishing, user authentication, remote management and Web services, which fully meets the campus network to develop network TV;
7. The audio and video are fully synchronized, and the live broadcast delay can be controlled within 2 seconds;
8. Video output code stream 8kpbs-2000kpbs adjustable, audio output code stream 8kpbs-160kpbs adjustable, the sound image is clear, smooth, no pause, audio and video are fully synchronized;
9. The unique technology can ensure the smooth transmission of network data without generating network spikes;
10. Provide timing operation function, the administrator can control the time to provide network TV, making the system very flexible;
11. Provide timing recording function, can use hard disk recording, provide on-demand viewing function of recorded programs, watch if you want to watch, stop when you want, watch at any time;
12. Support NAS storage server, large-capacity hard disk, can record programs at any time;
13. Provide users with an intuitive and friendly operation interface, ordinary users can easily use and skilled operation without special training;
14. Support cascading applications. According to the characteristics of modern universities, it can provide an application mode of building a live network server on the main campus and a distribution server on the branch campus, which greatly expands the application of network TV.
4. Comments on the plan:
This solution is mainly aimed at the campus network, which provides a professional and highly integrated one-stop idea for building campus TV stations, making network TV construction easier and more convenient.
The highlight of this solution is that TV2AV-16 can be seamlessly connected with AVCaster, reducing the redundancy and signal attenuation caused by the traditional single AV cable, and making the network TV more flexible and fast.
