Re: Picture Issues

Go to solution

My Internet speed is c.500 &  said speed is @ my TV.

I have always suffered BT pixelation Issues on the Ultra HDR channel but never on HD channels which does not make sense to me.

BT ,yesterday, played around with Speeds to zero effect & one Expert was surprised my  Extenders lacked a reset-button.

Another TV Expert arrives next week.

Sky has always performed perfectly but has just become SO costly.

My Broadband Contract was up last week but BT offered me a Package I could not refuse.

I believe the HD Picture is the best money can buy.

Before I sell my Body to Research & re-join Sky is there anything else I can try please ?

Not a solution as such, but have you tried watching TNT Sports via Discovery+ on your box? I don’t think there will be anything on there in Ultimate until Friday night’s Ireland rugby union match, but you could try that before the next tv expert arrives. Do you have the same problem on Channels 465 & 433? I realise that watching via Discovery+ is c30/40 seconds behind the multicast channels. We’ve only got FTTC and max out at 51mbps, but we use PLAs and get a perfect picture on 433&465.

Buy a long ethernet cable & try that temporarily. Obviously UHD requires a higher bandwidth than HD, & the way that channels are delivered over multicast requires that to be 100% sustainable. So random speed tests aren't much use as that's only a snapshot.

I can get it momentarily on any channel & it was BBC1 last night with 4 Incidents.
3 recordings I have watched have shown no pixelation to date.
I have been chasing Ultra HDR for years & BT then said speed was the answer.
As stated before it is the HD Issues that baffle me

I'd read your previous comment in the opposite way to how you meant it:

"I have always suffered BT pixelation Issues on the Ultra HDR channel but never on HD channels which does not make sense to me."

i.e. I thought you were saying you'd never experienced issues on HD.  What you're saying is that you're now experiencing issues on HD where you didn't previously.

Is there any possibility of temporarily moving the TV and TV Box to directly next to the Hub and using either WiFi or Ethernet to completely eliminate the Powerline Adapters from the issue?  If it works perfectly then alternatives can be explored.  If it still fails then a more complex analysis of your line conditions will be required.

@Tel2 

As @DarrenDev has said, you need to confirm what your issue is as you appear to be contradicting yourself.

I have visited 2 TV shops in Nottingham this morning.

One sells Bespoke TV's & the other an EE TV/Phone Shop.

Both independently queried my Extenders until they found out BT supplied them & when, they knew I had the Full Fibre

500 Mbps package, they both suggested the Router or Set-top box were suspect.

Hi @Tel2 what model PLAs do you have ? All recent PLA types (BT or Tp-link) should have a reset button and a recessed factory reset pin hole - your symptoms match characteristics packet loss between the hub and TV box which is why the UHD picture is so badly affected compared to HD (UHD channel playout rate is 3-4x higher than HD) and are very likely due to the PLAs struggling to find a clear channel on the in-home electric ring main. Knowing what model you have will help in diagnostics.

The ping time is indeed high as previously mentioned and the number of packets reporting as "lost" even on the BBC One Midlands East HD (generally 8-9Mb/s) is very high and will impact your picture quality.  I can understand why TV shop might suggest the router or TV box as they will not generally be aware of how live (multicast) TV is delivered over broadband.

First off I'd suggest ensuring the PLAs are reset and clearly paired, not on any extension / surge protected plug or having any switching power supplies (like mobile phone chargers) from adjacent sockets

. Might also be worth comparing how your Wifi signal strength is between the Sh2 and TV box to check if it's any clearer - just unplug the ethernet cable from the back of the TV box and use the network settings to join to the hub using WPS if possible.

Thanks

David
