Nucleus Name DS_SYS_VideoLoop
Nucleus Number 1215
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
VIP using DS_VIP_Routing .
