Channel 9 Signal from Foothills

Yes, I live in Athelstone and Channel 9 is bad for pixelation, usually during their own promotional ads. I have had the antenna guy out to install quad shield cable etc. These ads of Channel 9 contain a lot of white. Does this contain more info in the signal which the STB is struggling with.

I am at a loss but it is frustrating. Other channels are OK.

Anybody have any ideas?

All,

There is a few common causes of pixellation

1. The encoding process the TV stations use particularly if the orginal program was in analog PAL.

2. The other which usually is accompained by sound chirps is insufficient signal into the STB. Then this is usually an antenna installation problem. It can be aggrevated by switching of mains power.

The last possibility is in the display where it is LCD or plasma.

Please read Get the best reception

Which transmitter and which antenna

at the start of this strand, Check the coverage area links and see which transmitter you should be receiving.

blublurag,

As far at the digital signal from the transmitter to the receiver is concerned the picture content is irrelevant. That being the case if there is pixellation only in large areas of white, it should happen to all. This is not the case.

You also do not say if there is chirps in the sound.

If there is large areas of white and the picture rolls and pulls, it is a problem between the STB and the display.

Check the antenna installation according to my pinned post.

Thanks AlanH. Will do some investigation. And yes, I do get chirps in the sound.

Have got it working finally, done a few things.

Replaced my Thompson with a TEAC PVR, certainly better but still not good enough.

New Antenna, Matchmaster DG91, beautiful. Wish I had done this in the first place. Still some problems in the middle of the day in good weather, have turned the masthead amplifier down, suspect it was putting the signal out of the receivers range.

:blink: Glad you got it working - nothing worse than chirping sound. I get a bit of that especially on channel 9. It annoys me. The rest of the channels are generally OK.

I feel I might have to upgrade the antenna.

I live in Myrtle Bank which is a fringe area relying on Grenfell Tower.

Anybody know of any good digital TV contractors. I am not happy with Mr Antenna. I had bad experience a while ago during analogue days and would hesitate to use them again as you get different guy every time.

Cheers

Tom

TTB,

I used Damien from DigiTech (his own business). He was good and has lots of experience with the Genfell Tower foothills situation.

:blink: Thanks for that blublurag.

I will give him a call. I have the LG 5100p crunch box and some people say that the early versions were susceptible to sound chirping and crap like when switching channels, the audio arrives a bout 5 seconds later then the videa and crap like that.

I bought mine in 1/3 quarter of last year so I may have the earlier unit.

I will give Damien a call and see what he has to say.

Cheers

I'm still having a few troubles at certain times of the day. Was OK for a while during winter but the nicer weather seems to now cause problems during the day, channels 2 and 9. Mmmm.

Antenna is a Matchmaster DG91, Kingray Masthead Amplifier, Quad Shield Cable, TEAC SD PVR.

I have been up on the roof quite a few times trying to get it just right.

I seem to have the problem where I need to turn the amplification up at certain times but then this causes me problems at other times and I have to turn it down. I need to get it fixed as I am worried I am going to fall off the roof one of these days :blink: .

Is it worth trying something such as this...

Turn the masthead amplifier up and put a variable attenuator inside so I can turn it down when required. This would also help keep the analogue signal up for other TV's in the house.

OR

Turn the masthead amplifier down and have another amplifier inside that I can adjust up if required.

Anybody with more knowledge than me have any thoughts?

Thanks.
