IP production stream is so close to me

I vaguely feel this time IP The production flow is so close to me , As in TV packaging （VSS,AR and Gfx） Neighborhood neighborhood neighborhood close 8 Technology of , I was very lucky to join at the beginning Vizrt, I can learn about the trends of some international stations , About 2 Years ago, I heard that a European TV station realized IP The transformation of Urbanization , At that time, I began to look for information about this TV station IP Some information about chemical transformation , But there are no following reasons , After that, there was no domestic IP The movement of melting , Everything was put on hold . Until recently I met a living NewTek TriCaster.

Contact TriCaster It's less than 1 Months , But the information learned from all aspects , It has deeply shocked me , As a technology, I don't know that such a huge technological change has taken place now .

First , I want to borrow it Dr. Andrew Cross（NewTek Of CTO） A few words in a program , Roughly meaning “ When I see all kinds of digital equipment cameras , mobile phone , The computer , TV can be connected to the network , But the video output and input methods used are different , When you can pass your program youtube Let the global Internet audience see , But in the studio, the video signal can't be transmitted for a meter through the network （ Studios are using SDI Line ）.” Let's first understand what he said .

Let's first introduce TriCaster, I think he is based on Windows Broadcast guide system , Support SDI and NDI. What is? NDI？ The simple understanding is SDI Web version of .TriCaster It has occupied almost all the live broadcast of E-sports OB, Many large companies , Almost all schools use , I just learned . What I have always imagined is that radio and television equipment can be like OA The office system is as competitive , Only then can there be vitality , Don't just think about selling at a high price , Make the whole industry dead , Finally, waiting to be revolutionized by others .

NDI yes NewTek To launch the IP Stream standard , This standard is open , Safe to use , So now many radio and television equipment manufacturers have supported NDI,NDI No need for professional switches , Gigabit network switches can , Probably exist on the network at the same time 100 Lu HD NDI flow , I don't know if you have considered the existence of video matrix here, which is of little significance , Through the network protocol, you can freely allocate from the switch NDI Signal source , The existence of video plates is also of little significance , Besides being compatible with traditional radio and television equipment , So how much can you save , How much will the architecture of the whole system integration be simplified .

Of course NDI The stream of is compressed , There is also a traditional radio and television equipment manufacturers launched IP Stream standard SMPTE2022, I don't know much about that , It is said that 10G Switch support . I am now more resistant to professional equipment , Pay more attention to the solutions of the public . I think the public needs a high sex ratio solution , So that more people can afford it , Then high-quality content will naturally appear , Instead of just relying on some excellent studios , Let a hundred flowers bloom .

In the final analysis, why do you feel like leaving this time IP The production flow is so close , because NDI The standard of is open , Companies or capable integrators can make cost-effective solutions that meet their customers , All of a sudden, the customer base from the traditional radio and television , Expand to all walks of life , High cost performance, but it retains the high standard of radio and television .

Here I would like to remind you NewTek I used to work in radio and television , The preliminary understanding is about 20 Years or so , They launched NDI It's equivalent to putting the previous 10 Most of the products in recent years have been abandoned （ Because it's all based on SDI Of ）, But their transformation of the traditional process is very thorough , You can add code to your software to output directly NDI,NDI The use is also not based on boards and matrices , Unlike some video board manufacturers, they also launched IP Streaming hardware board , But the input device cannot be found , The output device cannot be found , All kinds of difficulties , I think it's all IP It's gone , You can't rely on the computer's own graphics card and CPU To solve the problem ？ I have to produce a hardware board . contrast NewTek It's really short-sighted .

It may be that they were NDI Flow influence is too large , So there will be some bias above , I'm sorry , I'll share it with you after I know it for a while . I suggest you try it NDI tool The toolkit , There are many things that are particularly useful , for example ：scan converter The interface of any desktop application can be transformed into NDI flow , And then directly TriCaster You can use it .
