|smp01||I was a victim of a lot of pixelation back when it was popular. I have not changed anything and I have not noticed any problems with this in a number of months now.|

|57||I've moved your post to this previous thread on the topic. Pixellation is a result of a poor signal. Macroblocking is a result of compression artifacts as discussed in post 2. Others may feel free to comment.|

Has anyone noticed an increase to pix-elating lately?
Wow my 630 is really bad. It is especially noticed when;
Changing channels. It is like it is not on the station. When I hit "Recall" and then go back it is okay?
When recording one feed and watching another. When the recording starts the channel I am watching starts to pix-elate.
Recorded shows are badly pix-elated when they are being watched?
What the hell is going on with SD? The dish has been recently re-aligned and current strengths are in the 90+ range with ECB at 9-10. From what I understand these are good numbers.
Man I am sooooo fed up with this provider it is a good thing they are not within driving distance as I would really like to talk to the morons that are running this outfit.
We should pick a date in March where we all call to cancel our contracts to see if they realize who the real foundation of this business is!!

|robman50a||I understand now, thank you 57. It is indeed macroblocking (example 'The Voice') . Now I also know that pixalation is those colourful blocks on my screen when I got the OTA feed on and the weather is bad.|

|robman50a||Well I noticed that the quality of Cogeco compared to Shaw Direct was a huge difference. On cable there where blocks on every channel and I have learned that was due to the compression on the CATV system. With SD the picture is way more better and there are hardly ever any blocks.|

I assume you're talking about macroblocking. An appropriate optimization of the TV can minimize macroblocking by turning down the sharpness, using the proper picture mode, etc.

The OTA feed does likely have less compression and therefore less macroblocking.

Any one know how to reduce the amount of pixelation?
I have been seeing a lot of artifacts on some of the HD channels on my plasma TV, not so much on my LCD and none on my LED TV.
I am using the DSR600 with HDMI.
For example when 'The Voice' was on you would see pixelation clearly on the faces and in the background.
Could it be there because of a setting on my TV? Like contrast or sharpness may be to high?
I did switch inputs to the OTA feed and the picture was beautiful but then when I switched back to the DSR600 there where the blocks.
The signal level was strong though coming in.
