"hui zhou gaoshengda technology" (Huizhou Goldman Sachs Technology Co., Ltd.) is a Chinese manufacturer of wireless/wifi modules. (just translate this site to English in your browser - http://www.gaosd.com/home). Scroll to the bottom to see the different manufacturers using them.

Not really "spoofing" your IP address of your Hisense TV, but is actually the MAC address of your wifi module inside your Hisense TV that is being assigned an IP address by your router to give the TV its internet access. (without a wifi/network module, your TV would not have an IP address since it cannot connect to a network or the internet without such a module).
A simple test is to unplug your Hisense TV. You should see the Huizhou drop off your "connected" devices list.
Additionally, you could also block/pause the associated MAC address of Huizhou in your router (or an accompanying router/ISP app, if available to you) and then see what device fails to connect to your network or internet when needed/used if you have multiple smart devices that may be using these modules.
