However, its biggest drawback is its slow transmission speed and extremely high latency. This means that the time between the initial request and the first receipt of the requested data can be very long.
Everyone is used to this mode, and the files transferred are all small and compact, with small data volumes. But when suddenly encountering a super large file, such as one over 10MB, it feels like it will take several days to download.
When I was working on 2.4G file transfer, I implemented a peer-to-peer wireless transfer method, also known as P2P technology.
2.4G technology is only suitable for short-distance transmission, such as tens of meters. It is not suitable for use in space, where the minimum distance is hundreds of kilometers.
Therefore, the requirements for wireless transmission technology are very high.
In this P2P technology, it's not like those "donkeys" or "thunderbolts." It refers to satellite-to-ground transmission to a server.
It did not bypass the server to transmit to other users, while the P2P technology of some donkey bypassed the server to transmit to users.
As for those "thunder" types, they're peer-to-peer servers. If you want faster download speeds, you have to pay and subscribe to a membership for the server to speed things up.
Furthermore, Xunlei's technology involves stealing files from its users and storing them on its servers. Whenever a similar connection occurs and the file is present on its servers, it can either speed up the download or limit your download speed. If you're in a hurry, you're forced to subscribe to a membership to download.
Obviously, the technology of a certain company cannot be used to transmit data from a satellite to the server on the other side, but there are many solutions to speed up P2P peer-to-peer transmission.
So Xing Baohua told Qiu Jun a simple solution: just create a download system software. The photos taken by the satellite wouldn't need to be stored on the satellite's hard drive; they could be downloaded directly to the hard drive array cabinet on the ground server.
In this way, satellites do not need large-capacity hard drives; they only need sufficient cache space.
The downloaded images will be automatically deleted.
There's no need to worry about compression technology; even if you tried to compress it, it wouldn't be much!
Recovery decoding technology cannot be solved by software alone; it also requires hardware support.
To avoid unnecessary trouble, Xing Baohua chose to download it directly from the file transfer server; a 10MB file wasn't very large. Besides, 10MB was just an estimate; it might be larger or smaller.
Even with the technology of this era, if it were to develop further and professional cameras were to mature, the resulting images would be clearer and the file sizes larger.
It's like a joke: a primary school teacher asked students to experience life skills by taking pictures of small animals and plants.
One student's father is a professional photographer with equipment worth over a million yuan; he's extremely professional.
The device uses high-capacity hard drives for storage, and can hold four 10GB drives each.
After the student finished filming the video, they sent it to the teacher as a compressed file. The teacher saw the compressed file spinning continuously, and was stunned when they saw that the file size was 12GB.
Further down the line, a single photo won't be handled by 10MB; it might even need to be gigabytes, which would require even more bandwidth.
After talking with Qiu Jun, I first asked him to take a look at the satellite's professional camera. This is our domestic technology, and one lens can capture 100 million pixels.
Unlike other digital devices that claim to have 100 million pixels, it is actually just the pixels from many cameras stacked together.
But the actual main camera only costs tens of millions.
The question is, why does a phone need so many cameras?
This varies depending on the scenario and the technology used. Secondly, there's the camera software on the phone, which involves a lot of technology.
As mentioned before, most mobile phone camera lenses use Sony or Leica technology.
Despite boasting tens of millions of pixels, it doesn't produce images as good as a fruit with 12 million pixels.
This is not a problem with hardware technology, but rather the accumulation of software technology, continuously refining and modifying the spectrum.
Does the satellite need these? No, so Xing Baohua wouldn't ask Chen Shuoyue's side to develop the software technology.
Only small cameras developed for use in mobile phones, laptops, and tablets will have low pixel counts, and the clarity can only be improved through technical means.
Xing Baohua was extremely busy when Xie Yingying told him that Old Mou had made another appointment.
“I won’t see you. Just say I don’t have time this year,” Xing Baohua said decisively.
He previously tricked people into thinking he was tiling, and who would have thought someone would actually take it seriously and actually raise funds for it? He even used his name to get several acquaintances in the capital to call and ask if it was real.
Xing Baohua felt he had embarrassed himself internationally. A venture capitalist was also inquiring whether Xing Baohua was in charge of the operation. If he was, they would invest as well.
This guy is a big shot in the investment world. When others look at projects, those who know him only observe his actions. Others who want to get on his bandwagon usually can't.
Xing Baohua thought Lao Mou had asked him to take over the tile-laying project, but he had told him from the beginning that the government didn't allow it and the project was off.
But now that they've come to her again, Xing Baohua is getting annoyed.
If they piss him off, we'll shut down his air freight business too, and see how much he makes then.
Xing Baohua also muttered about Lao Mou's lack of patience; this guy was blocking the company entrance. Since Xing Baohua's car wouldn't stop, he went to his house, but couldn't get in, so he came back early the next morning to block the entrance.
This man was also a business tycoon. At that time, Lao Mou was also very wealthy. He didn't care about the company's operations; he just focused on blocking Xing Baohua.
The traffic jam continued until after New Year's Day. Xing Baohua couldn't stand it anymore and called him to his office. He said to Lao Mou, "I'll give you ten minutes. I'm really busy at the end of the year. I have a lot of large projects waiting for me to handle."
