Unicast: Point-to-point connection, i.e. the "opposite" of multicast 
which is one to many (or many to many). In this mode, a transmit unit 
sends video data direct to a unique destination address. 
VLAN: Virtual LAN, a network of units that behave as if they are 
connected to the same wire even though they may actually be 
physically located on different segments of a LAN. 
Watermarking: A mechanism to "stamp" video content with unique 
marks, making it possible to trace the origins of illegaly distributed 
content. The marks are invisible for the viewer. 
XML: eXtensible Markup Language. A very common self-describing 
text-based data format. Used for many purposes: Meta-data, 
configuration files, documents, etc. The readability of the format has 
made it very popular and is now the fundament for many types of WEB 
services.
