Description The Codec generates a video signal with a specific signature and sends it to the output
of the digital board. The user selects which video input path must be routed on the
digital board and a video standard. The Codec encodes the video signal, checks the
signature, and returns a conclusion.
Note: Before executing this nucleus the user must route the video signal on the analog
board with the proper nucleus.
