Nucleus Name
DS_SYS_VideoLoopThroughStart
Nucleus Number
1213
Description
The video signal, which is conform the user input, is routed from the input to the
output. The input is set using the proper nucleus to route the signal on the
board(s). All outputs are enabled.

Note:
When a DTT module is in the set use DS_DTTM_SwitchCVBSPath as well !
Firmware Upgrading & Diagnostic Software
Decode the user input for the proper port to use
Write out the bytes through the indicated port
Description
Writing the bytes to the UART succeeded
The user provided wrong input
Writing to the UART failed
Decode the user input for the port to read from
Read from the port and return data read to the user
Description
Reading the data from the UART succeeded
The user provided wrong input
Reading the data from the UART failed
Decode the videosignal: PAL / NTSC and Y/C, RGB, CVBS,YUV
Initialise the Video Input Processor and check for valid signal
Initialise the Video Front End and start capturing frames to memory
Initialise the SYNC module
Initialise the Video Post Processing and retrieve frames from memory
Initialise the mixer
Initialise the DENC module
Route the signal to all outputs
