Whenever i watch moving sport especially football I experience

What you are seeing is one of the two problems that are well know about the "MPEG-2" system that is used to encode digital TV.

Because of the way the system works, horizontal movement across a crowd requires a disproportionate large amount of data to encode.

Because the bandwidth on Freeview is so limited, and as most broadcasters have decided to have more channels rather than better quality pictures, on most channels the bandwidth is so limited that the effect you see, a blurry mass of blocks is visible.

The sceptical will say that this is simply an excuse to sell you HDTV equipment and channel packages.

The other problem you will see is when strobe effects are used - this will often look like very large black and white boxes.

If these effects trouble you, do not go out and buy yourself a massive TV as they will be simply much clearer to you.

Thought I would add my son's comments.


He's correct that given a stereo feed, you have to select PL2, and your
onkyo does this for you automatically so you don't need to.

What I'm saying is that I think BBC1HD is broadcasting some shows in 5.1
but where the centre, rears and sub channel are silent. Ie they should
be broadcasting 2.0 so that the onkyo can choose to apply PL2
processing, but by sending a stereo feed in 5.1 (where L,R have content
but not C,SL,SR,Sub are silent) they're doing it wrong.

Whether you can force PL2 processing on a 5.1 feed I don't know... And
what it would do when you get a real 5.1 feed I don't know...

Thank you for reading my problem. My Matsui HD ready TV has a built in freeview receiver but the free hd channels do not come up during any scan for channels. No mention is made about whether these free HD freeview channels are watchable on this TV via it's own receiver in the manual for the TV. Is this due to the TV and it's receiver or something else. the ariel is on the roof and reception of signals is very good. The TV is 18 months old. Thank you

I have an analogue tv connected through a digital tv box.This produces a decent picture. I have now bought a new 32inch digital TV. the picture quality particularly on peoples faces and on outside broadcasts , football racing etc, appear to be blurring at the edges. What is the cure ?

P.JONES: Check for 'sharpness' settings in the TV's configuration menu - though usually they come configured with too sharp a setting.

A new TV will usually have a native HD resolution, and have to upscale SD broadcasts, so some blurring is inevitable as the screen resolution is not an exact multiple of the SD picture's resolution. Again, worth seeing what options are available to correct this.

I'm on freesat with a Humax Foxsat pvr, and whilst the Humax Diagnostics show 100% for both Signal and Quality, I am getting "blurred" pics particularly on SD.Is this an alignment problem with the Dish. I've tried different TV settings. Should "sharpness" control be high or low? although it seems to make little difference.

David Harold Constantine: Turn sharpness off.

But yes, the pictures will be blurred in SD, that's why HD was introduced.

I presume you are using an HDMI cable from the box to the TV?

Tks for reply.Yes, using HDMI cable. Is it possible that Dish needs realigning inspite of displayed 100% signal and quality ??

David Harold Constantine: No, do not move your dish. As a digital service the signal quality cannot effect the picture. Please see www.ukfree.tv link icon How digital television works | ukfree.tv - independent free digital TV advice .
