18 TVP5160EVM User’s Guide
If the WinVCC4 autoswitch polling function is enabled, then the detected video standard status
from the TVP5160 decoder is polled until a change in the input video standard (or in the
TVP5160 sampling mode) is detected. When a change is detected, the video encoder is
reprogrammed as needed for the detected standard. Using this feature, the video source can
change its video standard and the system will display using the new standard without user
intervention.
To enable autoswitch polling (recommended), the video-standard autoswitch polling function
must be enabled in the Real–Time Polling dialog box as shown in Figure 10. The Real–Time
Polling dialog can also be accessed once WinVCC4 is up and running by clicking Real–Time
Polling in the Tools menu.
