    Three key elements of live broadcast system development

     

    After 2016, various live broadcast APP platforms have sprung up, and the demand for live broadcast system development has also grown rapidly after entering 2017. Of course, everything has two sides, and so is the development of live broadcast systems. With the increase in demand for the development of live broadcast systems, the three inevitable key elements of the live broadcast platform at the technical level have slowly entered people's field of vision. So what are the three key elements?
    1. Caton
    To a certain extent, the resolution and delay of Caton are contradictory. There are three reasons for stuttering. The first is that the host will get stuck in the uplink, and all viewers will get stuck. The second is the stuttering caused by the internal network of the CDN, such as fluctuations in the transit network, uncontrolled node load, or some Networking strategy problems, the third is the scheduling and terminal network problems, such as DSN mismatch, or last-hop network jitter. There must be a monitoring manual to be able to find the main problem points and deal with them in a targeted manner.
    2. Delay
    In addition to the video GOP cache mentioned above, the second delay mainly comes from accumulation. In addition to frame skipping and other logic, it can also be improved by changing the transmission protocol. For live broadcast services that require high delay control, such as interactive live broadcasts, it is not at all Will use a protocol such as TCP for transmission, but will choose UDP protocol. Because for this kind of live broadcast, all the data of the video can be discarded, but priority should be given to ensuring the instantaneity of the audio.

    3. First screen opening speed
    The opening of the first screen tests the networking mode of the live CDN, the network coverage and the optimization degree of the transmission protocol. Li Hao specially reminded that this year's requirements for the opening speed of the first screen are getting higher and higher. The second opening is already the index requirement of last year. This year, it will be refined to a few hundred milliseconds. If this level is not achieved, there will be no competitive advantage. At this point, choosing a reliable CDN is particularly important.
    From the above three key elements, it is not difficult to see the importance of CDN in the development of the live broadcast system. In the view of Yunbao Network Technology, the first domestic service provider engaged in the development of live broadcast systems, breaking through the node limitations of CDN and the multiple choices of CDN has become an inevitable development trend of live broadcast technology. In response to this problem, Nokia's live broadcast system took the lead in launching the "Cloud Leopard Live Overseas Version" and the background CDN switching function.
    Although the technical requirements for live broadcast are complicated, Nokia Siemens Networks still insists on overcoming every technical problem. Of course, by overcoming these three key issues, the user experience of the live broadcast will be basically guaranteed.

     

     

     

     

     

     

    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

    1KW ~ 2KW FM Transmitter : 50KM ~100KM

    2KW ~5KW FM Transmitter : 100KM ~150KM

    5KW ~10KW FM Transmitter : 150KM ~200KM
