Videostrong KII Pro
Features
Videostrong KII Pro is a android based set top box, with DVB tuners integrated, it can receive Live digital TV - both FTA (Free to Air) channels.
Videostrong KII Pro VS Mecool KII Pro
There were different versions of this TV Box, all made by the same manufacturer.
Videostrong just happens to (re)sell some of their products under the Mecool brand, with different hardware.
The 2 known versions of the KII Pro are the "original" KII Pro (the version this port is made for), which uses the Amlogic S905 SoC, and the newer Mecool KII Pro, which uses the Amlogic S905D SoC instead. They both look the same except the newer one most likely has a Mecool logo on the front, and the Mecool KII Pro seems to use Android 7.1.1 instead of Android 5.1.1.
Linux
There are work of proting mainline linux to Videostrong KII Pro. For example a device tree that in the mainline linux ,etc. Postmarket OS has a port for it that use mainline kernel.

Availink AVL6862
The AVL6862 (AVL6862TA-CA23(?)) is a demodulation chip from Availink. It supports terrestrial television (DVB-T/T2), satellite television (DVB-S/S2), as well as cable television (DVB-C).
Drivers and firmware
The AVL6862 has drivers that will eventually get upstreamed by Availink.
- AVL6862 driver (from CoreELEC's downstream media_tree repository)
- AVL68X2 and AVL62X1 drivers (from Availink, apparently temporary as they will upstream those)
- chewitt's modifications (just adds a Kconfig and Kbuild)
- Firmware (also from Availink, will be upstreamed)
RafaelMicro R912
Drivers and firmware
- R912 driver (from CoreELEC's downstream media_tree repository)
- R848 driver (taken from a downstream kernel)
The status of drivers
The are some wip minline drivers in https://github.com/chewitt/linux/commits/dvb-sucks but there are no demux to combine the audio/video data output from them into something that can be played due to lack of demux driver in the mineline.
