TELETEXT FORMAT PICTURE & SOUND CONTROL

Doubling character height

Repeatedly pressing the HEIGHT button Manual background (A23) doubles the character height in the following order:

Upper half of the page (UP) > Lower half of the page (DOWN) > Return to normal height. If the page is in UP or DOWN mode, then normal size is automatically set if :

-A new page request is made (e.g. CYAN, INDEX or PAGE UP/DOWN).

-CANCEL mode (A8) function is used.

-VOLUME menu is activated the with the MENU button (A19).

Note : The menu at the base of the screen is always visible

Volume and brightness control in teletext mode

VOLUME ( and sound MUTE), BRIGHTNESS and CONTRAST controls are all possible in teletext. The BRIGHTNESS and CONTRAST controls are dedicated to the teletext display.

-Access the VOLUME control by pressing the MENU button (A19) in teletext mode. A barograph will appear in the lower part of the screen (as in TV mode). If MUTE is active a mute icon is also shown.

-A second press on the MENU button (A19) will access the BRIGHTNESS control, and a third press the CONTRAST control.

-The active bargraph will timeout after 3-4 seconds (as in TV mode VOLUME control) or by pressing on the MENU button (A19) a fourth time (after CONTRAST control)

-Each control can be adjusted by using the remote control CURSOR RIGHT (A20) / LEFT (A7) buttons.

-Mute can always be activated by pressing the SOUND MUTE button (A2).

-Any change to the VOLUME level will cancel the SOUND MUTE.

WATCHING TV WHILE PAGE SEARCHING

The CANCEL function can be used to make the teletext page transparent, thus revealing the TV picture:

- To enter cancel mode, press the CANCEL Manual background button (A8) while in teletext mode. The TV program will reappear on the screen, while only the teletext page number remains at the top and left corner of the screen.

- You can enter a new page number in this mode only by using the remote control NUMBER 0...9 buttons (A3), or with the INDEX Manual background button (A18).

- If a page has been requested, but has not yet arrived, "???" flashing characters will be displayed until the page arrives. Otherwise, the same characters will be displayed without flashing until the next arrival of the page in the transmission cycle. Once arrived the page number will be displayed.

-The teletext page can be made visible again by pressing the CANCEL Manual background button (A8).

-It should be noted that the TV program cannot be changed while in cancel mode.

WATCHING TV WITH TELETEXT SUBTITLES

If the actual teletext page is a news flash or subtitle page, then most of the TV picture becomes visible. In this situation the ZOOM format chosen in TV mode is reactivated, where possible.

This is particularly useful while watching a program with the teletext subtitles. Only formats which do not allow the full height of the TV picture to be seen are not possible in teletext mode, as these would not allow all teletext lines to be displayed.

Therefore only the formats ZOOM 14:9 AND ZOOM 16:9 (available with wide screen TV models) cannot be preserved with teletext subtitles. In this situation the default format FULL SCREEN (equal to 16:9) will be used.

For FAVOURITE format, FULL SCREEN will also be used only if the vertical size chosen is greater than 100%.

Note : A 16:9 or 14:9 format can be realised by keeping a 100% vertical size, but reducing the horizontal size, thus allowing teletext subtitles to be used over a picture that has no distortion.
