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.
