The 4K@60 frame live encoder is a high-end product, and the options are relatively small. There are several single-chip microcomputer chips in the Taiwanese chips that can do encoding, but the functions are too simple and the application range is relatively limited. Among the SOC chips, this specification can be achieved. Yes, there are relatively few options. HiSilicon, Novatek, Ambarella, Rockchip, and Aixin have products of this specification, but generally the prices are relatively high. Novatek NT98530 is the best cost-effective. The following focuses on the advantages of the NT98530 solution.
The technical framework diagram is shown above.
This solution has many advantages, the specific advantages are as follows:
1. It can support a variety of input interface extensions. For example, if some users want to access the DP interface, they can support it with slight modifications under this framework.
2. Support video storage, and can use a variety of storage methods, SD/TF storage, U disk storage, SATA hard disk storage.
3. The secondary processing of images can be realized, such as beauty algorithm, character overlay and image fusion.
4. Support audio and video synchronous processing or separate processing. Support mic array.
5. Support local display output, support display UI design, support menu.
6. Support dual network ports, which can be used to isolate the live broadcast by dividing the internal and external networks.
7. Support multiple wireless transmissions.
8. The encoding end and decoding end can use the same chip.
