Non-standard Teletext-Time transmission on TG4

Antenna

Non-standard Teletext-Time transmission on TG4 - On TVs with a button (can be marked 'time' or something else) on remote control that displays the current time (extracted from ordinary teletext) in corner of the picture - there is a problem in doing so on TG4:

The attached two pictures show this on a Beko TV, the time from RTE1 displays fine - but on TG4 the first digit is missing - 20:34:40 displays as "0:34:40 ".
Some other TVs (such as a JVC I tried - time is displayed on that by pressing 'i' button twice) might display correct time as set from the last channel with correct formatted teletext time (since last switch-on), however if TG4 is the only channel (with teletext) received since last switch on there is no time displayed.

The problem is apparently caused by the time being left shifted by one character from the norm in TG4's teletext transmission. Go into TG4's teletext ('Teacs') and compare the exact position of the time in the top line of the screen with other channels' teletext. It is one character left of the norm (on other channels with teletext).

RTE1 time from teletext


TG4 time from teletext - with 1st digit missing - time should be 20:34:40


both pictures on a Beko NR21271TDS CRT TV - on that TV the time is displayed (provided the viewed channel has teletext) by pressing 'SUB' button on remote

Last time I checked TG4's teletext didnt even identify the name of the channel correctly (same story with RTE2) :rolleyes:

Sloppy amateurish incompetency

I've seen RDS time wrong on RadioNaG. Is this some Irish language feature? I never did Irish at school so I have no idea.

Newstalk is always wrong too by about half an hour.

Its a disgrace that the regulators allow broadcasters away with this sort of thing.

Many clock radios use RDS to synchronise their clock functions (the whole point of the RDS CT feature in the first place)

RDS encoders should have the CT feature disabled by default and it should be only be enabled when it is synchronised with a GBR/MSF/GPS type clock.

In the early years of Téacs TG4 the time was provided using the 12hour clock. Seems to use the 24 hour clock now, the clock feature must not have been changed hence the missing 2. The Téacs time is now 22:10.

How do video recorders/PVR's which use teletext to set their clocks cope with TG4 text ?

I assume that the clock is right only it isn't displaying the first digit.

Yeah we have a SilverCrest (Lidl) kitchen radio which does this and is often half an hour to many hours off. There doesn't seem to be any way to choose what station it picks up the time from either, or tell me what station it is getting the time from. Very annoying.
