Picture Quality
Hi,

Can any of those who have received their unit comment on the PQ in relation to an A400?

Thanks!

RE: Picture Quality
Remember the NMT is the premium av line with Sigma chips the 400 with vxp so its always going to win.

Horses for courses, get a chameleon for android features xbmc netflix etc but for top line av go NMT.

There's been rumours of a linux xbmc sigma chip for some years now.

Thats what we need.

But is Chameleon's picture quality worse than a PCH A-210?

Regards.

NMT posts indicate VXP improves SD material and does nothing for HD material.

To educate us non-equestrians, re: picture quality, so strictly "v" and not "av", if we limit the discussion to say 1080p material, how would the OH be lesser than the 400?

RE: Picture Quality
Its not just all about VXP. The picture quality of the later series is better than the earlier as well. Just ask my non techy wife Big Grin

I read a good article about Sigma and its scalers. They have differing scalers for OSD, playback etc. whereas in Android presently its handled differently and cannot compete until it matures. Think it was in cnx or somewhere. Very interesting.

RE: Picture Quality
But isn't all this VXP just marketing? Is there really a difference these days? Isn't it down to codecs and the video engine processing capabilities of your TV set?

RE: Picture Quality
No, we have the ability to split the screen in Demo mode when setting VXP on the NMT. You can see the result pre setting.

The Hisilicon has some image processing abilities with IMV IIRC. Here's an article on Android 4K playback quality that'sa interesting:

As it has the OHC in the line up.

OHC > HDMI > TV (Panasonic 42G20)
Downmix stereo using standard Kodi(MC) 15.2 no hware/acc OK
Downmix stereo 1.0.40/RK Kodi(RKlib) 15.2 infrequent audio gaps hware/acc OK

No DTS downmix available for inbuilt eMC player

Gecko> HDMI > TV (Panasonic 42G20)
Downmix stereo using Gecko Kodi 15.0 OK
Downmix using inbuilt MediaCentre OK

I guess a lot has to do with how low level does each SoC, or specifically its library permit developers access in order to fine tune video quality settings. In other words unless I'm mistaken, how advanced the HAL (Hardware Abstraction Layer) is, which is how much developers see and can use in code.

Unless my eyes were fuzzy recently I actually thought SW decoding in MXPlayer looks better than when HW decoding is turned on (more sharp and little to no artifacts). Try the same on another SoC solution and the results could be completely the opposite of course.

I personally wouldn't overlook how much of a role modern TV's play though, some high-end sets have video engines that offer advanced tweaks before displaying the image on-screen.
