4;2;2 in the first video is unproven.
******************
Second video ; 4;2;2 proved. But there is an SD channel.( 576i ; so, mpeg2 )
CPU usage is too high ;
Because feeds are usually published as Mpeg4, the evidence in this video is useless, so…
******************
Previously, someone tried out HD video from Kodi. But it didn't work and KODI made the device a brick.
******************
Since "4;2;2" is a commercial sampling type, hardware manufacturers avoid giving hardware-based support to "4;2;2".
That is, hardware-based decoding for "4; 2; 2" is only available in commercial products. Expamle product ;

As for the consumer products front;
E.g; one of the sample products. For Windows device ;

The easiest way to solve "4:2:2" is to use one of the devices running windows. Of course, even with this device "4: 2: 2" will be solved with the help of codecs ! But the good news. The processor load will be no more than 35%. ( For 720p/1080i/p & H.264 videos )
*******************
Okay, why do we have to solve codecs in consumer products with "4:2:2" ?
See; even graphics card manufacturers avoid solving hardware-based "4:2:2"
******************
So, so, so… Need Windows Media Player device + tv card.
Enjoy.
