JS:

The curly brackets are extraneous, read it as if they are not present and it makes perfect UK English grammatical sense. Why they are showing I don't know.

Between this morning and this afternoon BBC News HD and Aljazeera HD have both vanished (no signal on 107 or 1108). No changes are indicated here, so what has happened?

The missing programmes have just reappeared on UHF channel 32 which now carries programmes previously on 55. Nice of them to let us know.

Brianist - can we please have an update!

Just realised that I'm probably getting a weak signal from Moel y Parc.
So, what has happened to UHF channel 55 on Winter Hill?

There is some engineering work at Winter Hill this week which might mean a weak signal from time to time and temporary loss of multiplex(es).
For those that have lost some muliplexes altogether, there was a retune event on March 7th which would have been advertised.
Go to Digital UK - Coverage checker and put in your postcode and tick "Detailed view". This will show you predicted reception and the current UHF channels for each multiplex.

Robert Lee: BBC News HD is still on the COM7 mux and is still on UHF55.

MikeP: The Al Jazeera HD event is on now so I've grabbed the EITpf off Freesat, ASTRA and Freeview:

Freesat_pf:

Al Jazeera Eng, Tue 01 May 2018 02:00 - Tue 01 May 2018 03:00: The Coming War On China
Journalist John Pilger, reveals what the news doesn't _ that the world's greatest military power, the U.S. may well be on the road to war with China.

ASTRA_pf:

Ep.2 Journalist John Pilger, reveals what the news doesn't - that the world's greatest military power, the U.S. may well be on the road to war with China.

We see an underscore character on Freesat; a dash or minus sign on ASTRA; and garbage on Freeview.

MikeP: All EIT title and description strings, for services on the DVB-T2 multiplexes, are Huffman coded.

I've had to modify my decoder to deal with these errant characters as follows.

Here, lastchar is the currently decoded byte and decode is the decoded string so far:


Select Case lastchar

Case &HA, &HD, &H20 To &H7E

decode = decode + Chr(lastchar)

Case &H19

decode = decode + "{'}"

Case &H13

decode = decode + "{-}"

Case Else

decode = decode + "{hex=" + Hex(lastchar) + "}"

End Select


I'm using the curly brackets to identify and locate the fixes in the output.

The output is an xmltv file.

If I try to open the uncorrected xmltv file in my xmltv viewer application, it responds with an error message giving the line number and position in the line of the error and refuses to proceed further.

Just done a full autoscan of Panasonic TV and Humax and C55 has reappeared! Which begs the question "why did it disappear yesterday", and why didn't a manual scan of C55 work?

I thought that the duff characters appearing in the Freeview EPG were confined to the Huffman coded strings for services on the DVB-T2 multiplexes.

I've just noticed that the same duff characters are also in DVB-T EPG data.

I don't have a Freeview HD device so I asked if someone who has would report whether the suspect characters were rendered properly in the events I listed.

I'd like to thank all those who informed me whether or not that was the case.

Now I see these duffers on DVB-T, I can check myself, no longer needing your valuable assistance.

The duff apostrophe with code 0x19 appears in 349 events over the next 7 days.

Here is one such event:

Blaze, Fri 04 May 21:00 - 22:00: Flipping Bangers
Alfa Romeo: Gus and Will are after an Italian car. They can[0x19]t afford the true classics so they let they budget dictate the vehicle and settle on a 155 from the '90s.

So how did my LG telly render the [0x19] in what should read "can't"?

It completely ignored it, outputting "cant".
