BRIAN: The broadcast EPG is sent in tables with different table IDs for different types of data.
The Schedule data uses a possible 16 tables for up to 64 days, each table carrying 4 days worth of EPG data.
Only the first two tables are used in the UK, providing an 8 day schedule,
There are separate tables for "Now and Next".
More information is needed. What is the Model of the TV? What exactly does "only one day" mean? The more you can tell us the better.

ASTRA/BSkyB Diffs:
An encrypted HD test named 52586 was added to the BSkyB service tables:
Comparing files List ASTRA 03-12-2019 18 01.txt and List ASTRA 04-12-2019 11 01.txt
************************ NEW ************************
SERVICE NAME TYPE EPGID SID TSID ONID FREQ.P ENC EIT PROVIDER BOUQUETS LCN
52586 25 1203 52586 2116 2 11427V 1 1 BSkyB 000000000000010 1031
At present, only the PMT and ECM streams belonging to 52586 are present. The video and audio streams advertised in the PMT are absent.
What makes 52586 of interest is the transponder it's on: 11427V.
11427V currently has four HD services on it, all of which are on Freesat:
S4C HD
FRANCE 24(ENG)
FreeSports HD
QUEST HD
Whilst looking at 11427V I noticed FreeSports HD had lots of missing packets.
Further investigation showed that the video and audio streams were dropping out for a few seconds every minute or so.
This is reflected in the bitrate measurement for 11427V:
Video Bitrate (Mbps) sampled at 32 <= dPCR <= 43 ms intervals over 17 seconds for 11426.50 V 29500 8/9 DVB-S2 QPSK (04/12/2019 16:46:51)

That was at 16:46 and it's still dropping out now at 21:20.

Digital UK (or is it just Freeview now) have some ZERO WIDTH SPACES on offer this week, courtesy of BBC 6 Music!
A short-form error summary follows:
Invalid Character Codes in the EIT off North West multiplex BBC A. Date: 2019/12/05 00:59:54
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 976 invalid codes in the current EIT:
invalid code, count, percentage
0x08, 24, 2.46%
0x0B, 2, 0.20%
0x13, 4, 0.41%

Chris.SE: Thanks. Amazingly, my "dog nose" comment turned out to be entirely appropriate.

Chris.SE: ... Khyber. Still not updated. I get the impression they don't care much about traditional transmission anymore. The BBC push iplayer in your face at every opportunity and ridicule people who don't want to use it, in their "iplayer: wasted on some" advert. Well, I for one, refuse to use it. They can stick it up their .....

Chris.SE: Do you really want to lay yourself on a plate for the scrutiny of MI5TV?

Chris.SE: Very funny. I wonder what the neighbours think.
The last time I accessed the BBC site, I was presented with a page about George Orwell, informing that he worked at the BBC, though no documentary evidence of it existed.
I wonder what Orwell's "Big Brother" was, that watched everyone.
That new "smart" TV you've got, are you watching it or is it watching you?
Incidentally, Orwell's real name was Eric Blair, the same surname as the pathological liar and blood-drenched war criminal whose wars, as with many others, were facilitated by the BBC.

Chris.SE: Would that be a "Magic" remote for an LG?
I was thinking about that "watch this programme from the start" option, and how it might work.
It seems as though it requires a personal stream for every viewer, but that would be impossible if the number of viewers was large. Anyone know how it works?

Freesat4 was renamed to Freesat Info and added to the test region with LCN 901 on SD, HD and G2 devices.
Freesat Info is not the same as freesat info, which appears on SD and HD devices on LCN 999 but confined to the test region on G2 devices:
