If it was a live broadcast, the choice of computer configuration needed to be determined according to the live broadcast content and requirements. If it was a simple live video broadcast, it did not involve complicated operations and AI special effects. It did not have high requirements for the computer's performance. Ordinary computers or even nuclear computers could satisfy it. If you want to livestream a game, such as an FPS competitive game, it is recommended to use a computer with a standalone display. It is best if you have a sufficient budget. As livestreaming required a lot of memory, 32GB was better, and the CPU should be as high as an i7. The requirements for streaming 3A games were even higher. If it was a livestream teaching 3D modeling and other content, the configuration would be similar to a game livestream. If it was just a business office or a text and picture live broadcast, a computer could meet the needs. For multi-platform live streaming (3 - 4 platforms), the recommended CPU is an i5 - 13600K (with a nuclear display is best), the default memory is 16Gx2, the best is a 2.5G network card on the main board, the recommended graphics card is an RTHX4060 (best is an RTHX4060Ti), the power supply cannot be too poor, the heat dissipation must be good, and the case should be good. The minimum requirements for a typical live streaming computer were: an 11th generation i5 CPU, 8G of memory, a GTX1050Ti graphics card, at least three USB ports, and a 500G hard drive with a USB port. Higher configuration can be added on top of this. In addition, you also need to pay attention to the choice of cameras, microphones, earphones, and other equipment, as well as the stability of the network connection. It is recommended to use a cable network to ensure that the upload speed is at least 5 Mbit/s. The live streaming software could be selected according to one's needs, such as OBS Studio (open source and free), Streamlabs OBS (suitable for beginners), XSplit (paid software, friendly interface, suitable for advanced functional requirements), vMix (professional level, suitable for multi-camera switching and complex scenes), etc. While waiting for the TV series, you can also click on the link below to read the classic original work of "Dafeng Nightwatchman"!
