5 Virtual Cards
5.1 Introduction
A ‘virtual card’ is a collection of controls from a number of cards on the same frame that appear
as a single extra card. The virtual cards feature can be used to limit user interaction, simplify
operation or assemble features for specific control purposes. The virtual card creation process
involves direct editing of an XML file which is then put into the frame front panel; this is offered
as a chargeable service by Crystal Vision or can be carried out by someone familiar with XML
editing. What follows is a guide to the process of creating a virtual card.
5.2 What you will need
1. A text editor – ideally Oxygen http://www.oxygenxml.com/ with the CV 'external tool' so
you can see what your virtual card will look like on VisionWeb.
2. Telnet and FTP access to the frame containing the card(s) you want to incorporate into
your virtual card.
3. The XML files for those cards. You can get these from the Registered Area of the CV
website
http://www.crystalvision.tv/support/registeredarea/registeredarea.html
support.
4. The virtual card template file.
5.3 Summary of what you have to do
1. Decide what controls you want on your virtual card and how you want them grouped.
2. Get the XML files for the 'source' cards from the website.
3. Pick a 'virtual slot' number for the virtual card. Make a copy of the template file and save it
with a filename including the 'virtual slot' number for the frame.
4. Customise your template file so that it refers to your specific virtual card.
5. Create the menu structure in it and populate the menu structure with controls copied from
real card XML files, adding a reference to the real card (its slot) and the original control ID.
6. Check the validity of your XML file against the CV schema file. This is a standard XML
editor function.
7. If you are using Oxygen with the CV tool you can also generate an HTML file to check the
control arrangement is what you want. Copy the file into the correct directory on the frame.
8. Reboot the frame.
9. The virtual card will now be available for use.
