Yes, I'm sure. You are confusing PQ with pixelation/interruptions in picture. There's an excellent post in an old thread about this. You may read it.
I have read that but I still believe there is some flaw in that post as picture does not comes in single 0 or 1 but there are around 1 Million 0's and 1's and some 0 and 1 can be wrong where picture correction technique takes place and picture correction will not always be perfect and picture quality gets decreases.
If you are experiencing pixelation then its definitely due to signal issue only. However smudged or lower resolution picture are not due to signal issues. The PQ is affected by bit rate and encoding algorithm used. Missed signal will result in pixelation. All data is checked for errors. So if the checksum is not correct then entire group of pixel is rejected. Ultimately it all depends on software used. If error correction is not strict then PQ can deteriorate slowly and not in blocks.
So does that means signal quality does not have any affect or it can have some effect as the checksum correction cannot always be right? If Signal strength is more and signal quality is less than it mean you are getting some incorrect bits and signal correction is taking place as signal quality decreases, checksum of part of picture can also fail and pixelation/defect will start appearing and PQ will start decreasing.
In Airtel we don't experience single point pixel issues when signal fails. Just blocks of pixels appear. Also transmitted signals have redundancy. i.e multiple bits are repeated. So there is a level of signal to noise ratio that will not result in any checksum errors.
I tried manually and software upgrading started and completed successfully. However after restart it is still showing 618. So I guess there's no 619 yet. Forcing update only overwrites the same version.
