1. Background:
In the past few years, some live TV satellites have been launched in the Asia-Pacific region. In addition to Japan already having live broadcast satellites, Russia, South Korea, Thailand, and the Philippines also have live broadcast satellites and live broadcast satellites in disguised form. Almost all domestic use Thai UBC live broadcast satellite (referred to as Taixing live broadcast). The advantage of live star is that it can cover dozens of high-quality satellite digital TV programs with 60cm or smaller antenna in the service area of ​​live star. With the development of broadband, people are increasingly demanding the transmission of analog and digital satellite signals on the Internet.
Looking at the current streaming media technology, the most important one is whether there is a complete set of digital resource management system. In Microsoft's latest operating system, Windows Server 2003, we were pleasantly surprised to see a new and powerful streaming media management system, which is Windows Media Services 9 (hereinafter referred to as WMS 9), and the streaming media server HVC 400IP network video live broadcast The system uses it to embody high-definition live broadcasting.
Second, the function
Mainly live broadcast of TV channels, live broadcast of 4 channels of TV programs through campus IP network, and real-time analysis.
1. It can also realize 4-channel live broadcasting on wide area network satellite signals, on-site recording of campus activities, video conferencing, VCD, DVD, AV, DV and other signals. The high-performance compression hardware algorithm is required, the sound is clear and smooth, and the image displayed on the receiving end after transmission has no flower screen and mosaic phenomenon.
2. Support WMV and AVI files that can be recorded into MPEG-4 files in real time while recording the compressed signals in live broadcast.
3. The system can accommodate more than 1000 users to watch programs online at the same time.
3. Analysis
Real-time live broadcast of TV programs, and real-time analysis. The Taixing signal is received and converted into an AV signal through a high-quality satellite receiver or other equipment. It is directly collected and compressed by a compression card to the HVC 400IP network video live broadcast system, and then the live broadcast is realized through the server.
To watch live satellite TV programs live on the campus network, this requires the system to have high transmission rate, data synchronization, data stream distribution, high stability and other characteristics. And the best solution to realize the video and audio transmission of the network is the transmission method of streaming media. The system compresses AV video signals into MPEG-4 video and audio streams while live broadcasting and stores them as WMV or AVI video files in real time.
4. System Structure
1. Network bandwidth requirements
TCP / IP protocol, 100M or 1000Mbps export
2. HVC 400IP network video live broadcast system
Hardware configuration: Xeon 2.4G CPU, 512M memory, sound card, 100/1000 network card Software configuration: Windows Server2003 + Nowsteam live broadcast system software5. Advantages and characteristics of HVC 400IP network video live broadcast system
In terms of compression and encoding, it is currently more popular to use a video compression card plus software compression, but this greatly improves the video picture quality, delay, and especially stability, and consumes less CPU resources. (About 10% of the live broadcast all the way); hardware compression meets all the requirements for high-quality, high-definition live video broadcast! Previously, because there was no dedicated hardware compression chip, there was no corresponding hardware encoder in the market, but now the HVC 400IP network video live broadcast system provides us with a low-cost, high-quality hardware compression and live video solution!
HVC 400IP network video live broadcast system is a high-quality streaming media management system that can provide DVD image quality at a low bit rate of 2Mbps. It is a product based on single-chip compression technology that supports multiple formats. Using multiple algorithms to compress and connect the original video and audio signals into different format stream files, thus ensuring the synchronization of video and audio in time; operating systems supporting multiple platforms include: Win2000 / XP, Windows Server 2003, Linux, etc. Nowstream is a set of software specially developed for the HVC 400IP network video live broadcast system. It comprehensively uses the latest computer network technology and streaming media technology, and has a very broad application prospect.
