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.
Technical - Evaluate user input.
- Reset the global variables, video memory.
- Fill the video memory with a vertical colourbar.
- Initialise the Codec SYNC-module.
- Initialise the Codec MIXER-module.
- Initialise the Codec VPP-module.
- Initialise the Codec DENC-module.
- Display the original image.
- Initialise the VIP.
- Initialise the Codec VFE-module.
- Try to detect a sync in the VIP input.
- Catch the received image in memory.
- Display the received image.
- Compare the received image with original image.
- Create a conclusion.
Execution Time 3 seconds.
User Input <VideoSignal> <VideoStandard>
1. Video Signal (CVBS,YC,RGB,YUV,DTT).
2. VideoStandard (PAL, NTSC).
