7.11.6 Option Card Plug-and-Play
The unit is designed around a plug-and-play concept to make it as easy as possible
to add new option cards and functionality. This means that the chassis and Host
controller card provide a base level of functionality, while any specific functionality
associated with an option card is contained on the option card itself.
A good example of this is MPEG SI generation. The Host controller provides the
functionality to generate and play out the SI required by a Transport Stream.
However a VCM is required to provide any descriptors required for any elementary
stream types that it generates.
