Hi @quanglam68
welcome to the Stereolabs community.
Ubuntu porting on NVIDIA Shield TV is not an official distribution, so we cannot provide technical support.
The device is equipped with a Tegra X1 processor, that is close to the Jetson Nano in performance (maybe a little better).
It seems that the installed OS is Linux for Tegra (L4T) v32.7.2, so unofficially I can say that you could try to install the ZED SDK v3.8.2 for Jetpack 4.6.1.
Let me know if it works, my Engineer side is curious.
