Mark Winfield: Looking at the spec, this set has a satellite input but does not have Freesat. Thus, if you have it connected to a dish, all you will see is Now and Next because that is all that is transmitted.

Freeview EIT Invalid Character Codes:

To enable anyone interested to see these code errors for themselves, I have uploaded some programme clips.

The clips were recorded by Tvheadend, which happens to record the EIT along with the video and audio streams of the programme.

The full eight day programme schedule repeats every thirty seconds so that determined the clip durations.

The schedules can be seen by installing MediaInfo: MediaInfo - Wikipedia

Download: MediaInfo

Once installed, right clicking on a clip shows the media properties of that clip.

If an appropriate view is chosen, the events scheduled for the next week are also shown.

The included file "North West_BBC A__2020 12 14 053417.txt" shows the events with errors in the current EIT, as determined by my EIT parser.

Looking at those events using the "tree" view, square blocks are seen in the text at the positions of the errors.

If the "xml" view is selected, the events with errors are not displayed because the characters are not valid in xml.

In that case you will see a representation in binary.base64.

An online base64 decoder: Base64 Decode - Online Tool

I have included the MediaInfo.xml outputs for each clip.

SportyStuffTV is called "22631" at the moment as it is yet to launch on BSkyB.

There is no Freesat EPG for SportyStuffTV yet but there is BSkyB EPG.

Mostly, it is running the same sequence of events repeatedly:

22631 Mon 11 Jan 15:00 - 16:00 : UK Strongest Man
Coverage of the UK Strongest Man competition (S2, E02)

22631 Mon 11 Jan 16:00 - 16:30 : Mobil 1 - The Grid
Mobil 1 The Grid is back with Series 12 and ready for the new motorsport season

22631 Mon 11 Jan 16:30 - 17:00 : Mobil 1 - The Grid
Mobil 1 The Grid is home for the most exciting motorsports on television, tune in for insider-track racing excitement!

22631 Mon 11 Jan 17:00 - 19:00 : International GT Open 2020
After celebrating its 200th race in 2019, the international GT Open runs its 15th season in 2020, confirming itself as one of the top pro-am racing platforms in Europe. Race 1 from the Hungaroring

22631 Mon 11 Jan 19:00 - 20:00 : UK Strongest Man
Coverage of the UK Strongest Man competition (S2, E01)

...

But then:

22631 Fri 15 Jan 18:00 - 22:00 : RPGTV Live Greyhound Racing
Live greyhound racing. For details of tonight's meetings visit greyhoundbet.racingpost.com. Contact the studio via twitter @RPGreyhounds or by email at rpgtv@racingpost.com


SportyStuffTV is unusual for an AVC HD service as not only is it on a DVB-S transponder but it is statistically multiplexed with MPEG SD services - something I've not seen at 28 degrees East before.

Monika: Signal Strength is virtually meaningless on satellite. Quality is what matters.

More info needed: You said "replaced sky box" - was that a sky q box?

What postcode did you enter for the Freesat box? - The first few characters are enough.

Channels are divided into two groups by polarisation - horizontal and vertical. If there is a fault with the polarisation then half the channels would be missing.

All those channels you mention - apart from maybe ITV+1- are horizontally polarised.

Freeview invalid EIT character codes update.

New information regarding these errors has emerged.

All the errors so far had been the low-order bytes of the Unicode General Punctuation Block, but not this one:

Al Jazeera Eng, Fri 05 Feb 20:00 - 21:00: Chocolate's Heart Of Darkness
The dark side of a $100 billion industry where enslaved children can still be found toiling the cocoa {0x01}elds for the chocolate we love and crave.

The invalid code in this case is the byte 0x01, which is the low byte of the correct Unicode Character 0xfb01

Unicode Character 0xfb01

Verified here:

Chocolate's Heart Of Darkness ALJAZ July 29, 2020 900am-1000am +03 Free Borrow & Streaming Internet Archive

Donate icon


So how do Freesat and Sky cope with this odd character?

Freesat replaces it with an underscore:

Al Jazeera Eng, Fri 05 Feb 20:00 - 21:00: Chocolate's Heart Of Darkness
The dark side of a $100 billion industry where enslaved children can still be found toiling the cocoa _elds for the chocolate we love and crave.


Sky replaces it with a question mark:

Al Jazeera Eng Fri 05 Feb 20:00 - 21:00 : Chocolate's Heart Of Darkness
The dark side of a $100 billion industry where enslaved children can still be found toiling the cocoa ?elds for the chocolate we love and crave.


Freeview puts out the invalid code 0x01

Jonathan : ITV no longer has region names so they have to be added manually.

I think this is correct:

Simon Shearn: Since the date of the last sample of SDN I can find, 17 September 2020, superfluous "Data Broadcast ID" descriptors have been added to the PMTs of:

Create & Craft
Blaze+1
TCC
ITVBe+1
ITV4+1
ITV3+1

If the reboots are caused exclusively by these then that might be the reason, but repeated descriptors shouldn't cause problems.
