Full strength but near-zero quality?

[J. P. Gilliver]

I'm on the Heathfield transmitter. I have two receivers, fed from the
same distribution amplifier. All the channels each can get are solid.

I noticed one was getting a channel the other wasn't, so looked into it:
it is a channel on multiplex "BBC B". On the set that isn't, I did a
manual retune on all six multiplexes - all show full signal strength,
but BBC B only shows a trace of signal quality. (I presume the other
channels on that multiplex are ones I'd not watch so hadn't noticed.)
The set does not find anything on that mux.

Any idea what gives? The sets are a Polaroid HD box, which gets all
channels, and a Panasonic TX-L22X20B, on which the mux (channel 47)
shows as above. (Obviously the latter doesn't get HD channels.)

My first thought was that there's some local interference in that
frequency area - but, if that was the case, surely it'd knock out that
mux on both sets, as they're fed from the same aerial and dist. amp?

I've just checked, and it doesn't get any other BBC B mux channel either
- or rather, _the_ other one. I see BBC B carries mostly the HD channels
- the only ones not shown as HD are 46 5SELECT and 66 TBN UK. Is it
perhaps that these, though I'd assumed SD, are actually T2 encoded,
which would explain why the Panasonic isn't seeing them? I thought SD
channels being T2 encoded stopped when TPTV came onto T1.

(Is it even possible for a mux to include T2 and T1 channels, or are
they mutually exclusive?)

[Andy Burns]

Is it even possible for a mux to include T2 and T1 channels, or are they

A mux is either entirely -T1 or entirely -T2, the channels within them
can be HD,SD,radio,mheg etc.

Interference can't knock-out some logical channels within a mux, if any
are missing it's down to lack of capabilities of the receiver (e.g. for
HD as you are aware).

A HD capable T2 receiver should see

46 5SELECT
66 TBN UK
101 BBC ONE HD
102 BBC TWO HD
103 ITV1 HD
104 S4C HD
105 Channel 5 HD
106 BBC Scotland HD
107 BBC Three HD
108 BBC FOUR HD
110 Channel 4 HD
204 CBBC HD
205 CBeebies HD

depending on time of day three/four or cbbc/cbeebies will be active

I'm not sure if the following channels (possibly internet streamed) are
cruft that is coming, or cruft that's gone?

Yes, DVB-T1/T2 are modulation schemes, they don't care about programme
stream forms or their video resolution that are contained within. You
can carry any type of channel, within either modulation scheme.

A T1 receiver will simply not 'see' a T2 mux (as JPG has discovered)

Not to be confused with DAB and DAB+. The two types of DAB format, can
(and do) co-exist with the same DAB mux. If you use a DAB radio, it will
normally display the presence of any DAB+ station, but you just get
silent audio.

That will be. Our LG Bedroom telly often refuses to produce sound on any

and back again, and then all is good.

Not an uncommon experience. I had the same in a Premier Inn near Gatwick
in September. I mentioned it in another forum, and others have
experienced exactly the same.

My suspicion is, that Prem Inn have not run a rescan on their tellies,
since (in England) BBC 1 HD was regionalised in April. The tellies
(Samsungs in all cases) haven't quite automagically adopted the new
regional versions of BBC 1 HD (which has different PIDs to the old
'England-wide' version)

When I stayed recenty at a Premier Inn (in Evesham), BBC One HD didn't work

One thought, not sure but they might be able to tell that someone has
been using the maintenance mode to change settings. If someone
complains about the TV set and they find that then they might bill the
person who did it (which they can find from who had the room at that
time) with the cost of correcting it - that would probably be expensive.

Rather like if you smoke a cigarette in the room then you can be billed

Someone complaining about receiving more channels than are advertised
are unlikely to complain. If you do what has been suggested, just make
sure the hotel's own porn and movie channels still work.

As for the cost of "fixing" it, it takes a few minutes at most if you
have the right code, and the only reason to charge you for it is to
discourage you from going back.

That does incur real and high costs for the hotel, as the next occupant

We stayed in a hotel near Cirencester this week.

The telly in our room was diabolical. It was a Philips. The remote had
no 0-9 keypad, so the only way to select a channel was from the EPG
page, and/or stepping up/down with P+/-.
That took forever to load. ITV SD (on LCN 3) was missing, yet C4 and C5
SD were there (same mux, go figure !)

BBC 1 HD was completely absent, but the other HDs were there (almost
certainly no rescan sine the BBC HD regionalisation) In fact the smoking
gun for that was Russia Today was still there (as a blank entry of
course) It did have GB News, but no Talk TV, or Sky News.

interesting.
So, basically, we _are_ still getting some SD channels on T2 - but only
those two. I had assumed that stopped when Talking Pictures TV managed
to get a T1 slot, presumably desired by them because a lot of their
target audience only have T1 receivers; I _think_ they were the only

I hadn't realised that TPTV had been on PSB3 at one time. I thought they had
been on one of COM7 or COM8, and moved to one of the current muxes some time
before COM7/8 disappeared in a puff of smoke. I wonder whether the move to
T1 was prompted by more of their audience having T1-only receivers or
whether it was because the COM4/5/6 muxes are receivable from more
transmitters than those which used to broadcast COM7/8. If they become even
more succcessful, they may afford to move to PSB1/2/3 which are receivable
even from Freeview Lite relay transmitters.

I *think* there have been some sub-SD (ie 544x576) channels on PSB3 for as
long as I've had T2-capable equipment.


If you are getting the sub-SD channels but not the HD channels on PSB3, then
your TV is capable of receiving T2 but for some reason gets a very poor
signal quality despite strong signal. Silly question: have you tried the
affected TV on the aerial output that normally drives the TV that can get
HD - to rule out one feed from your splitter being corrupted while the other
isn't?

I've downloaded the manual, it seems to date from 2010 ish, and the

The OP must have a later version that has a T2 tuner (possibly
half-arsely implemented), but the screen resolution is quoted as only
1366 x 768

I actually wonder if it can support 1920 x 1080 (in order to downscale
for display) So, it may well simply ignore anything it finds at 'HD'
resolutions.

What happens if you force a 1920 x 1080 signal via the HDMI input ?

No, I'm pretty certain it's T1 only. The processor is severely limited:

No, it _does_ ignore the BBC B mux. It shows it as full strength, hardly
any quality, and doesn't find _any_ channels there. (My T2 decoder box
_does_ see them - both 46 and 66 [well, I've never looked at 66], and
the HD channels.)

Some of the channels also appear blank but when you play with some of the

I am pretty sure that the Goodmans Smart talk box only gets sd that are on
sd multiplexes as there are channels missing which appear on the Samsung TV.

Yes, that multiplex includes two SD channels (46 and 66), but a T1
decoder won't see them, even though they are SD.

There is no such thing as an SD multiplex, as wittering Gaff is
going on about. Nor an HD multiplex.
There are T and T2 multiplexes. That is it. What goes on them is
a different matter entirely.

It something that is the root of the confusion that lead to this thread
being started in the first place !

Indeed. The British media and retail industries haven't helped by
referring to T2 and T1 as HD and SD. (I don't know if the same deception
- or at least oversimplification - was used in other countries; I
suspect not.)
