Re: Pixelation

Which channels? If you have your aerial connected then your Freeview channels will be through that and your subscription channels will be delivered by multicast.

Re: Pixelation

@Torquay40 It could beat couple of things. The most obvious is Freeview signal quality, and that will be down to how close too the transmitter you are, obstructions etc. Additionally, some of the groups of channels (MUX) are not as strong a signal. These are typically the lesser commercial channels. Sometimes, a better aerial will help.

Alternatively, if your signal strength is too strong, the BT boxes can beat bit fussy and a signal attenuator can reduce the strength (not the quality) and it can solve the problem. However, this is often seen as pixelation across more channels. I had this and the attenuator worked a treat.

Re: Pixelation

This is a problem I have had for years. I have had Pixelation problems on my TV but only on BBC channels.  A BT Engineer visited and said it was probably the signal being either too weak, or too strong. He checked the signal, it was maybe a little strong, and turned in down. Since then the Pixelation (only on BBC Channels) has returned with a vengeance. I therefore watch BBC channels through the TV directly, bypassing the BT Box. Then there  is no problems with the picture whatsoever. This indicates the aerial is fine. This does mean. however, that I can't record any BBC channels and have to watch programmes live, through the TV directly.

As BT seem unable to solve this problem, which appears to affect a number of other BT Customers, I have decided to contact the Chief Executive of BT and outline the problem to him. My contract with BT for the supply of a box in order to receive many programmes is not being honoured. BT are failing to provide the service they are contracted to provide. We are talking BBC Channels here, not some obscure channels. I have to have a BBC Licence to watch the TV that I can't record and only watch in real time. 

In my opinion, BT are in breach of contract. I am paying for a service that only provides half of what it is contracted to do. I have not been offered a discount or any method of solving this problem and it seems from the comments in this column not many others have either. The BT service we all pay for is not cheap. There are numerous alternatives, (used by many friends, neighbours, et al) who do not have these issues. Their contracts are cheaper than BT anyway.

If BT refuse to cancel my contract and do not rectify these issues then I will take this matter to the Media (newspapers, broadcasters and BT competitors).

I will write directly to the CEO and see if he is able to shed some light on this matter. I suggest other BT customers suffering these problems do similarly.

Kind Regards

Re: Pixelation

Hi @Terrior and @Torquay40 and thanks for posting.

Sorry you're having problems with pixelation. I've had this myself and as @SoupDragon57 has mentioned an attenuator sorted the problem out. I think it's worth a try in this instance.

Cheers

Re: Pixelation

Many thanks for the tip, David. I know very little about attenuators. It appears you have to have the right one, which entails engaging the services of a professional. Is it likely to affect the service to other channels? Will I be prevented from watching BBC channels on TV directly? 

I will investigate this option, however, but at the end of the day I still think it's BT's responsibility. Thank you again.

Kind Regards

Re: Pixelation

Hi @Terrior ,

I just got one from a local retailer and connected it. Worked first time so maybe I got lucky. Only cost a few quid so deffinitely worth investigating.

Cheers

Re: Pixelation

@Terrior  @DavidM  I got an attenuator online possibly eBay). They're cheap and you can get a selection of strengths (resistance). Youview boxes are apparently notorious for issues with signal being too strong. I'm sure if it was too weak, then an aerial specialist would have advised.
I run mine via internet mode these days, but I have kept the attenuator on the feed into the TVs.
