Streaming media refers to the media form that transmits audio, video and multimedia files in the network by streaming. Compared with the network playing form of viewing after downloading, the typical feature of streaming media is to compress the continuous audio and video information and put it on the network server, so that users can watch while downloading without waiting for the whole file to be downloaded. Due to the advantages of streaming media technology, it is widely used in video on demand, video conference, distance education, telemedicine and live online system. As a symbol of the new generation of Internet applications, streaming media technology has developed rapidly in recent years.
Streaming media server is the core system of streaming media application and the key platform for operators to provide video services to users. The main function of streaming media server is to collect, cache, schedule, transmit and play streaming media content. The main performance of streaming media application system depends on the performance and service quality of media server. Therefore, streaming media server is the basis of streaming media application system, and also the most important part.
function
The main function of streaming media server is to transmit video files to clients by streaming protocols (RTP / RTSP, MMS, RTMP, etc.) for users to watch online; It can also receive real-time video stream from video capture and compression software, and then live broadcast to client by streaming protocol. The typical streaming media server is Windows Media Service (WMS), which uses MMS protocol to receive and transmit video, and windows media player (WMP) as the front-end player; Helix server of real networks company uses RTP / RTSP protocol to receive and transmit video, and real player is used as the front end; Adobe's flash media server uses RTMP (rtmpt / rtmpe / rtmps) protocol to receive and transmit video, and uses flash player as the front end. It is worth noting that with the popularity of Adobe's flash player (according to Adobe's official data, the installed capacity of flash player has reached more than 99%), more and more network videos begin to use flash player as the front end. Therefore, more and more enterprises begin to use flash player compatible streaming media server, And began to eliminate other types of streaming media server. Besides Adobe Flash media server, the streaming media server software of sewise and ultrant flash media server, as well as red5, an open source software based on Java, support flash player.

2.1. Using umsmonitor to configure UMS service
Umsmonitor is a tool software specially used to manage the ultrant media server software. With umsmonitor, you can easily start, stop and restart the ultrant media server service, and set various operating parameters. You can right-click the ant icon in the lower right corner of the windows tray to pop up the system menu, as shown in the following figure:
After the above menu pops up, select the "open ultrant media server monitor" option with the left mouse button to pop up the main control interface of umsmonitor.
On the main control interface of umsmonitor software, you can view the installed UMS related services and their working status through the "service status" list on the left. To manage a service, you need to first select the list item on the left, and then find the three service control buttons on the right, namely "start service", "stop service", "restart service", The corresponding functions of these three buttons are: start UMS related services, stop UMS related services, and restart UMS related services.
On the main control interface of umsmonitor software, you need to select the "ultra media server (UMS)" item first, and then click the "configure service" button on the right with the left mouse button to enter the ultra media server software configuration interface.
After the configuration is completed, you need to click "application" to confirm the modification, and then click "OK" to make the modification take effect immediately. At this time, the software will prompt you whether to restart the ultrant media server service to make the modification take effect. Select "OK" to make the configuration take effect.
2.2. Test the VOD function
To use the VOD function, you need to prepare a FLV format video file and copy it to any media library path (the media library path can be added through umsmonitor), or add the path of the FLV format video file to the media library path.
After the video file and media library path are ready, please make sure that the modified settings have taken effect and that the file name does not conflict. If you are using the nginx web server provided by the installation program, please add the vod.html Open the file in Notepad; If you are using an existing web server, set the UMS in the root directory of the web server\ vod.html Open it in Notepad and find the following code:
so.addVariable ('file','6 rooms.flv ');
so.addVariable ('start','0');
so.addVariable ('streamer',' rtmp://127.0.0.1 :1935/vod');
Change 127.0.0.1 to the IP address of your current server; If you use your own FLV format video file, please vod.html "6" in the above code in the file rooms.flv ”Change to the name of the video file you prepared.
If you use the nginx web server provided by the installation program, you can access http: / / {server IP address} through the browser/ vod.html To access the on demand page; If you use the original web server of your computer, you can access http: / / {server IP address} / UMS through the browser/ vod.html To access the on demand page.
After the play page appears normally, click the player to play.
2.3. Test the live broadcast function
You can use Adobe Flash Media live encoder 3.1, a free software provided by Adobe company, to test the live broadcast function of ultrantmedia server software.
2.3.1 install Adobe Flash Media live encoder 3.1
Please refer to Adobe official website for installation process and help.
2.3.2 preparation of camera equipment
You can use a USB webcam or a professional video capture card (which needs to be recognized by Adobe Flash Media live encoder 3.1 program) as the video source.
2.3.3 release live stream with Adobe Flash Media live encoder 3.1
Open Adobe Flash medialive encoder 3.1 software to ensure that the video capture device and audio capture device can work normally. The hardware devices that work normally should be as shown in the figure below:
Please correctly set the location marked by the red rectangle of the seat map. The URL address of the FMS URL should be "RTMP: / / {IP address of the server where the ultrantmedia server is located} / live", and the stream should be "livestream". After setting, first press the "connect" button. If the text on the "connect" button changes to "disconnect", it indicates that the connection is successful; Then press the "start" button marked in the bottom red rectangle to start the live broadcast.
2.3.4 viewing live video
If you are using the nginx web server provided by the installation program, please add the live.html Open the file in Notepad; If you are using an existing web server, set the UMS in the root directory of the web server\ live.html Open the file in Notepad and find the following code:
so.addVariable ('file','livestream');
so.addVariable ('streamer',' rtmp://127.0.0.1 :1935/live');
Change 127.0.0.1 to the IP address of your current server; If you rename the published video stream, set the live.html The "livestream" in the above code in the file is changed to the name of your own named video stream.
If you use the nginx web server provided by the installation program, you can access http: / / {server IP address} through the browser/ live.html To visit the live page; If you use your computer's original web server, you can access HTTP through a browser

How far(long) the transmitter cover?
The transmission range depends on many factors. The true distance is based on the antenna installing height , antenna gain, using environment like building and other obstructions , sensitivity of the receiver, antenna of the receiver . Installing antenna more high and using in the countryside , the distance will much more far.
EXAMPLE 5W FM Transmitter use in the city and hometown:
I have a USA customer use 5W fm transmitter with GP antenna in his hometown ,and he test it with a car, it cover 10km(6.21mile).
I test the 5W fm transmitter with GP antenna in my hometown ,it cover about 2km(1.24mile).
I test the 5W fm transmitter with GP antenna in Guangzhou city ,it cover about only 300meter(984ft).
Below are the approximate range of different power FM Transmitters. ( The range is diameter )
0.1W ~ 5W FM Transmitter ：100M ~1KM
5W ~15W FM Ttransmitter : 1KM ~ 3KM
15W ~ 80W FM Transmitter : 3KM ~10KM
80W ~500W FM Transmitter : 10KM ~30KM
500W ~1000W FM Transmitter : 30KM ~ 50KM
