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: 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".

The bad characters in the Freeview EIT are spreading.
The latest offender is BBC Manchester:
BBC Manchester, Thu 10 May 12:00 - 15:00: Becky Want
Becky chats to George Costigan about Long Day{'}s Journey Into Night which is on at Home.
Here we see {'}, which I have inserted in place of byte 0x19 to indicate an apostrophe was intended.
As it happens, 0x2019 is the Unicode for 'RIGHT SINGLE QUOTATION MARK'
And guess what?:
Sony Crime Channel, Sat 12 May 20:00 - 21:00: Person of Interest
No Good Deed: Reese and Finch{'}s lives are put in danger when their next person of interest stumbles upon the existence of {L'}The Machine{R'}. (S1 Ep22)
Where I have inserted {L'} in place of byte 0x18 and {R'} in place of byte 0x19.
As it happens, 0x2018 is the Unicode for 'LEFT SINGLE QUOTATION MARK'
And hows about this then:
Al Jazeera Eng HD, Thu 10 May 21:00 - 22:00: Al-Nakba
Four-part series on the history of Palestine and the events of 1948 {-} a year which the Palestinians refer to as the {L'}nakba', or catastrophe.
Where I have inserted {L'} in place of byte 0x18 and {-} in place of byte 0x13 to represent a dash or minus sign.
As it happens, 0x2013 is the Unicode for 'EN DASH'
None of these bytes are valid according to the DVB spec:
Digital Video Broadcasting (DVB); Specification for Service Information (SI) in DVB systems:
http://www.etsi.org/deliv….pdf
See Annex A: Coding of text characters.
The current culprits:
There are 388 bad characters over the next 8 days; this list is just an example from each of the services involved:

js: Whilst I'm unable to explain the reason for what you are seeing, I note that most of those channels are on Multiplexes operated by Arqiva with the exception of 4 that I spotted which were on COM4.
Maybe you could try contacting Arqiva to see if they could shed any light on the issue, they may be able to point you towards a contact for those that aren't operated by them.
Just another thought, are you able to reproduce those errors on another device so that you can eliminate the possibility of some bug that's cropped up on your receiver.

Chris.SE: Thanks for taking the trouble to reply.
I would be grateful if you could check the events I listed to confirm the errors are present on your Freeview device.
I did check on an LG TV and the code that corresponds to an apostrophe was ignored, so that what should be "can't" became "cant".

Chris.SE: The responsibility lies with Digital UK.
"Digital UK provides day-to-day technical management of the Freeview Electronic Programme Guide (EPG)"
http://www.digitaluk.co.u….pdf
Freesat and BSkyB evidently know how to manage the EPG data they receive from service providers:
Freesat:
Sony Crime, Mon 14 May 17:00 - 18:00: Person of Interest
No Good Deed: Reese and Finch's lives are put in danger when their next person of interest stumbles upon the existence of 'The Machine'. (S1 Ep22)
BSkyB:
Sony Crime, Mon 14 May 17:00 - 18:00: Person of Interest
No Good Deed: Reese and Finch's lives are put in danger when their next person of interest stumbles upon the existence of 'The Machine'. (S1 Ep22)
Freeview:
Sony Crime Channel, Mon 14 May 17:00 - 18:00: Person of Interest
No Good Deed: Reese and Finch{'}s lives are put in danger when their next person of interest stumbles upon the existence of {L'}The Machine{R'}. (S1 Ep22)
I would expect Freeview devices to ignore the incorrect codes, rendering what should be "Finch's" as "Finchs" and "'The Machine''" as "The Machine".
