Q. Can a 35" monitor be put onto a WorldCart?
A.Yes, a 35" monitor can be put onto a WorldCart only in the United
States and Canada.
Q. Does the Concorde•4500 support Annex-D graphics?
A. Yes, the Concorde•4500 does support Annex-D graphics; however,
the display is limited to 2 x CIF vertical and 1.5 x CIF horizontal.
The resolution of standard H.261 Annex-d graphics is 704
horizontal by 576 vertical. This resolution is 2 x CIF horizontal
and 2 x CIF vertical. Therefore, the total resolution of Annex-D
graphics is actually 4 x CIF.
The Concorde¥4500 is fully compliant with Annex-D graphic
protocols. The encoder sends 4 CIF sub-images to produce a
4 x CIF graphic. The decoder receives 4 CIF images to reproduce
the 4 x CIF graphic. However, the horizontal resolution is limited
to 512 pixels.
The limitation of the horizontal resolution is not linked to NTSC
or PAL resolutions, so it does not matter which one you have.
Q. Is there a smaller WorldCart?
A. Yes there is.
The part number is CART4.
Q. What is the maximum number of Speed Dial Entries?
A.There are 47 dual-line 25-digit numbers with full 6-character site
names. There are 69 dual-line 10-digit numbers with full 6-character
site names.
If any of the following conditions are true, a larger number of
entries is possible:
Less than 6-character site names are used.
Not all entries are dual-line.
The number of digits per number is less than is stated above.
