I have a video of the last Ceefax testcard shown on BBC Two digital this morning.

The page number was replaced with 010 ten minutes before the end, then 005, 003 and 001 as a countdown to the end.
The display used to display Teletext characters is the BBC Micro screen Mode 7.
This screen mode uses less memory than other screen modes, as each character is treated as a pixel.
The characters 0 to 255 are used to display a character, select a character colour or graphic colour.

... but can't afford a new TV, or don't have room for another TV, you can view HD channels on your old SD TV set.
HD on a SD TV set.
The picture quality will be 'standard quality' and not 'high quality'.
There will be no advantage viewing the HD version of BBC1, ITV1 or Channel 4,
but you will get the BBC HD programs. (Until it turns into BBC2 HD). Re: Hasan Loonat
You need two digital receiver to watch and / or record two different channels. Is it a Sky + box?
Most old analogue TV's and Video recorders had a built in analogue tuner, but if your current TV and recorder is plugged into the same digital box
and it only has one digital tuner then you can only view or record a single channel.
Try turning off your Sky box off at the mains for a few seconds, also check the cables are plugged in and no short circuits in the satellite cable.
On the top graph (Terrestrial channels) you also have a white line from 2011 for Channel 4.
Is there no data for Channel 4 before 2011?
Surprised how big the Channel 5 figures are in the 90's due to the very very slow interdiction of this channel.
They only managed to finally transmit to the who country at the end of 2012.

Digital text is ending on ITV and Channel 4 on 7/01/2013.
See Youtube youtu.be/AxwQY_r59TQ
or text page 362On your mapsofvhf.php page you could also add a list of the VHF transmitters so visitors can click on the transmitter name as well as the map to visit a page.
Also next to the names have the channel number, power, vertical horizontal etc. in a table.
EG.
Name, Station, Location, Channel, V/H, Power
Crystal Palace, BBC London & South East, TQ 339712, 1, V, 200kW
Croydon, TQ IBA Theams / LWT, 332696, 9, V, 400-kW Re: Briantist
The page looks good, thank you.
My Granddad made the first colour TV.
He had a black and green cathode-ray tube from an old radar display at the end of the war and used it to make a black and green 405 VHF TV.
They used to show fish in a fish bowl between programs, so the fish looked better in black and green than black and white.
Re: Mike Davison
Although teletext has ended on terrestrial TV and officially on satellite.
On BBC3 and BBC4 satellite (and possably other channels) there is a page 100 saying that Ceefax has ended.
Also on some channels on satellite you can still access the subtitles on page 888.
Go to BBC3 and press the subtitles button, then select teletext on your TV and go to page 888 and you will have two sets of subtitles.
P.S.
On my Sky box I can view Teletext with a TV connected using the UHF aerial lead,
but for some reason it doesn't work using the SCART lead.
This8s may be because I have the lead going thru a DVD recorder first. jamie and ANN SHORTALL snow on your dish will stop it from working.
If the signal dose not return when the snow has melted then the dish may have moved or water has got in the dish LNB socket.
What signal level do you have?
Press SERVICES then 4 then 6 for signal test. Ceefax has ended. (22/10/2012)
The BBC TV Center has closed. (22/03/2013)
And now the BBC HD channel is closing. (27/03/2013) :o(
Brian Wright, I heard somewhere that Dr Who will have a story in 3D this year.
Expect it will be on BBC1 HD and a normal version in BBC1 SD Mike Dimmick, Briantist
Is the testcard at 4:00 a 3D testcard?
See above video. If nobody uses Virgin Media and it doesn`t exist then zero people are useing it.
So how can you have a figure of -500 homes in 2012?
