Quoting from Wikipedia: High Efficiency Video Coding (HEVC) is a video compression standard and is regarded as the successor of the ITU-T H.264/MPEG-4 AVC standard. HEVC is believed to not only improve the video quality, but also achieve twice the compression rate of H 264/MPEG-4 AVC (equivalent to the bit rate reduced to 50% under the same picture quality), and can support 4K resolution and even ultra-high-definition TV ( UHDTV), the highest resolution can reach 8192>4320 (8 K resolution).
Simply put, H.265 is a new video compression standard. Its core value is to transmit higher-quality network videos under limited bandwidth. It only needs about half of the original bandwidth to play videos of the same quality. This means that users can enjoy higher-quality audio and video services at the same bandwidth cost.
1.What is the significance of H.265 to live and on-demand platforms?
Due to the high compression rate of H.265, most of the live and on-demand platforms are very concerned about its development progress. If H265 can be widely used in its own business, it can save costs, improve user experience, and effectively open a gap with competitors to occupy the market. But even if H 265 has an absolute advantage, the mainstream encoding and compression standard on the market is still H.264. What is going on?
First of all, this is because H 265 has higher coding complexity, so it consumes more power and takes longer. In fact, this is also easy to understand. Let's say, for example: You pinch a sponge, and if you want to press it smaller, you have to use more effort to pinch it tighter. In the same way, if you want a higher compression rate when encoding and compressing, then the compression algorithm will be more complex, the requirements for device performance will be higher, and the power consumption per unit time will be greater. Secondly, the encoding complexity of H. 265 has increased, making its decoding more complicated. At present, most players on the market are not specifically compatible with H. 265. Finally, it must be mentioned that the browser does not support H. 265 decoding. For many audio and video customers, it means that the method of sharing and acquiring new users is blocked.
This is not a simple technical question, it is a standard question. All the mainstream browsers currently on the market do not support H265 decoding. In other words, the videos recorded by your APP or live streaming cannot be watched by sharing to friends. You can not watch it on the web.
As we mentioned above, the encoding and decoding of H. 265 is very performance-consuming. From the hardware point of view, don't let the CPU do things that can be done by the GPU. In fact, Apple itself supports H.265 hard-coding, and in subsequent versions of ios 11, they will open this capability to all developers. This means that most of the i0s platform has entered the H. 265 era. But for those live broadcast and on-demand platforms for all ordinary users, it is not enough that only i0S supports H265. When you open the door to do business, you can't ask every customer to choose a mobile device according to their wishes. Therefore, if H 265 is to be further popularized, it must support soft coding, that is, use the CPU for H.265 coding, and control the power consumption within the normal range.
2.H.265 prospect prediction
On the whole, I think the prospect of H265 is very clear, and it is only a matter of time before it is widely popularized. Because it basically has a variety of unique conditions.
First: the support of giants. Apple's repeated mention of H 265 at WDC at least shows Apple's attitude. The hundreds of millions of Apple devices in the world will become a factor in the popularity of H265.
Second: the promotion of audio and video companies, because the popularity of H265 is directly related to the profits of many audio and video business companies. Imagine that if the bandwidth of a few Ts is saved at 50%, the extra-a large amount of profit is likely to make some live on-demand companies turn losses into profits.
Third: due to the fast update speed of hardware equipment, the further improvement of the performance of hardware such as mobile phones and PCs will cause the shortcomings of high performance requirements of H.265 to be gradually overcome.
Fourth: the upgrade of rich media, such as the rapid development of next-generation media such as VR and AR. These media have higher requirements for the amount of information transmitted per unit bandwidth than traditional media.

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
