How to build a live video system

It is planned to build a brand-new mode of live video platform, with 2W people watching online at the same time, the resolution is not less than 720P, and it cannot be stuck. What preparations need to be done? How high is the technical threshold? How much is the capital expenditure?

The technical threshold for a complete video live broadcast system to be built is very high, and it cannot be achieved by a startup team in a short period of time. So where is the high?

Audio and video technology is hard bones. It is not just a few pages or a business support system. This requires years of technology accumulation. For example, Tangqiao Technology, they have accumulated ten years of experience in audio and video technology, and it is not an entrepreneurial team that can catch up with them all at once.

The price of voice and video engineers is quite expensive, if not the most expensive IT engineer, it is also one of the most expensive. The voice processing modules include noise suppression, echo cancellation, automatic gain, forward error correction, frame loss compensation, jitter buffer, etc. Several modules are responsible for at least one module, and then to achieve cross-platform and full terminal compatibility, each platform must be One person must do it. Counting this up, the entire voice and video team has at least ten people. Assuming an average salary, ten people can get a lot of money for a year.

The development cycle takes at least half a year, and it is only possible for a first-class development team. After the development is completed, the effect is still unknown. A team once said that they are very powerful and developed it within a year, but the effect of echo cancellation and noise suppression is not good. I thought to myself, that is the core problem. If you haven't solved the core problem, can you be considered a good one?

The above is the threshold, if this threshold does not scare you, please continue to look down. Non-stuttering is a core feature, and low latency is another core feature. However, these two characteristics are a pair of contradictions: to achieve a good interaction effect, low latency is required; if low latency is required, the buffer queue must be made as short as possible; if the buffer queue is short, it cannot avoid jams. Therefore, the most compromised solution must be to find a balance between non-stuttering and low-latency, so that the lowest delay can be achieved when the voice and video are not stuck. The education live broadcast program provided by Tangqiao Technology to NetEase Cloud Classroom fully demonstrates the balance of these two characteristics.

The above also said that the technical threshold is high, and funding is not affordable for the startup team. The most important thing is time and opportunity costs, which are the lifeblood of startups. So the best plan is to use a third-party audio and video SDK like Tangqiao Technology, and leave what you are good at to those who are good at it, and you can spend more time and energy on operations, which is the best of both worlds.

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
