Whenever i watch moving sport especially football I experience much poorer picture quality with what i call 'ghosting', do I need HDTV?

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.

Hi,the definition of ghosting is a secondary image attached to the video which can be from indifferent
reception on analogue,mismatch of input circuitery,noise, too many units in line,poor cable where the
signal gets reflected back and forth in the cable.On analogue,there were cases in London where the
ghosting wasn't fixed ,this was called multipath.

As stated in my articles,mpeg 2 does suffer from stuttering or jerking effects particulary on fast motion
where there is insufficent bit rate to carry the video information but domestic equipment also has deliberate
noise added as per my previous articles and i have explained why.
