In the absence of any official info,could someone please give me the final and 100% correct details for the up and coming Winter Hill Freeview changes? How I originally understood the situation,was that PSB1/BBC A MUX,would be powered up on 19th Feb 2020,on UHF CH32 and the CH50 version would be simulcast for 24 Hours until the early Hours of 20th,when it would be discontinued. However i'm now hearing from some,that both CH50 and CH32 will be simulcast until April 22nd 2020? The Date of the remaining channels to be moved to Aerial Group T or W. I've emailed Freeview.co.uk again for clarification on this and also the situation regarding North Wales Winter Hill viewers and their Help scheme for the elderly,etc?

David Robert:

I posted very clearly on the 31st Jan. on p189 in response to Chris Gunn that the Simulcast continues until 22nd April. That post was immediately before your previous post. Perhaps you missed it.

As regards Help schemes, there is no help scheme for the Elderly per se. The Free Help that is available is organised by Freeview if someone contacts them and is not able to receive the 3 PSB multiplexes in particular on the new frequencies, but I believe it also includes the COMs4-6.
It is provided Free provided the person does not have Satellite or Cable. Age is irrelevant.

Chris. I took the information from the Digital UK/Ofcom Data for the Winter Hill Transmitter. Sadly I can't post you a screenshot of it here. The info in that clearly states that viewers will need to retune on 20th February,2020 and the New CH32 PSB1 MUX,will be powered up on 19th February,2020. I posted a screenshot of this on UK Free's Twitter Feed,relating to your posts and the Winter Hill Transmitter. I'm not doubting your info but somewhere along the lines,errors have been made in the info released? I note that there still is no response from Freeview.co.uk,to my request to clarify this? What a mess!

Yes, but it does NOT say on that page that the simulcast ceases on the 20th. You have read too much into that. If you search for the more detailed information about the retunes in the various other pages & documents available, it's all quite clear. Clearly you are doubting me because you haven't researched enough!

Reply from Freeview regarding the Winter Hill Retune(s)

Dear Mr. Roberts,

Thank you for your email dated 5 February regarding technical changes at Winter Hill.

The BBC A Mux will run in parallel (simulcast) until 22 April to help support viewers who may need a new aerial to receive BBC A on CH 32.

CH 50 will be listed from 751 in the TV guide temporarily. CH 32 will technically launch on 19 February but will not be configured to replace CH 50 'in the guide' until 20 February.

The retune should work from 10AM on 20 February.

Viewers who receive their channels from the Winter Hill transmitter (regardless of their location) may see pop up messages on screen advising the need to retune on 20 February.

In most cases a simple retune will restore any missing channels. If anyone is still having trouble getting certain channels back (following the event) then please encourage them to call us on freephone 0808 1000 288 for further support.

They can find out more information on these changes (nearer the time) and how it may affect them by visiting: Important changes to Freeview | Freeview before they call us, as they might be entitled to free home support.

Please note: Home support is only available for 3 months from the date of the retune event at each transmitter. Home support ends for the 20 February changes at Winter Hill on: 20 May 2020

Our usual opening hours are: Mon-Fri 9am-6pm, Saturday 9am-5pm.

Home Support:

If retuning does not restore the affected services, we may be able to send a qualified installer to the viewers home. This service is available when:
The viewers house has its own aerial and they don't have access to satellite or cable TV
The problems can be attributed to the frequency changes, and;
TV services cannot be restored by following our advice over the phone.
Our installers will investigate the cause of any reception problems and undertake necessary work, including installing a replacement rooftop aerial where required (includes loft and external wall-mounted aerials).

We do not provide in-home support to properties with shared aerial systems, businesses or
households that use a portable set-top aerial to receive TV services.

There is no charge for this service. Should any viewer arrange independently for an aerial installer to carry out work, we are not obliged to refund any costs they incur.

Thankfully at last some clear and concise info from Freeview.co.uk.

If you don't want clear and precise information from independent experts, why come here asking questions in the first place? The information you have got from Freeview is exactly what I've posted here in several recent posts!

Bad Characters Update:

I had thought, maybe, the BBC had finally eliminated the root cause of these errors in their EPG data, but no, they haven't.

The latest short-form error-dump follows:


Invalid Character Codes in the EIT off North West multiplex BBC A. Date: 2020/02/19 10:12:56

It has become apparent through observation that invalid bytes in the Freeview EIT text strings are the low-order bytes of the Unicode General Punctuation Block:

Of course only bytes less than 0x20 qualify as invalid codes in the context of EIT text strings.

Since about April 2018, the following invalid codes have been found in the Freeview EIT text items:

0x01, substitute: {0x01} -> Unicode Character: "EM QUAD" (U + 2001)
0x08, substitute: { } -> Unicode Character: "PUNCTUATION SPACE" (U + 2008)
0x0B, substitute: {} -> Unicode Character: "ZERO WIDTH SPACE" (U + 200B)
0x10, substitute: {-} -> Unicode Character: "HYPHEN" (U + 2010)
0x13, substitute: {--} -> Unicode Character: "EN DASH" (U + 2013)
0x14, substitute: {---} -> Unicode Character: "EM DASH" (U + 2014)
0x18, substitute: {L'} -> Unicode Character: "LEFT SINGLE QUOTATION MARK" (U + 2018)
0x19, substitute: {R'} -> Unicode Character: "RIGHT SINGLE QUOTATION MARK" (U + 2019)
0x1C, substitute: {L''} -> Unicode Character: "LEFT DOUBLE QUOTATION MARK" (U + 201C)
0x1D, substitute: {R''} -> Unicode Character: "RIGHT DOUBLE QUOTATION MARK" (U + 201D)

There are 1098 invalid codes in the current EIT:
invalid code, count, percentage
0x18, 15, 1.37%
0x19, 1025, 93.35%
0x1C, 29, 2.64%

The Code Rate for com8 was reduced to 1/2 a while ago.

Here are the current Bitrates for com7 and com8:

PCRs in each transport stream were used to calculate the bitrate.

Median values tend to eliminate rogue PCR results.

The values can be used to deduce the transmission parameters using a calculator such as:

DVB-T2 Data-Rate Calculator: DVB-T2 Data-Rate Calculator - Tools for Digital TV and Mobile DTV

Hi js, > The Code Rate for com8 was reduced to 1/2 a while ago.

It's believed this happened on the 12th Feb. when Sandy Heath and a few other transmitters had a retune, it was spotted on the Freeveiw Detailed Coverage checker for Sandy Heath reception and supposedly upcoming changes on WH on the 20th, and later dates for other TXs, but it seems they all must have changed on the 12th as one might expect because it's an SFN. Checking here on off-air it hadn't changed on the Monday (10th) but had later in the week!
