To assist users of a VYA module in understanding how it is to be applied, a simple example is to be provided in the form of a process network containing a frontend module, a backend module, a control module, and the VYA module in question. The frontend and backend should be links to standard VYA modules, e.g., for I/O of PFSPD files. This test bench should be accompanied by the makefile, initialization files where applicable, video test sequences, and the expected response to these sequences to allow module behavior to be verified. Preferably, a typical and an extreme sequence are provided for illustrating both normal and exceptional behavior. Test sequences should be as short as possible to minimize storage space and transmission bandwidth.
