8.3 I2C System Test The I2C system test of selected registers runs immediately after closing the WinVCC4
Configuration dialog box with OK (unless the I2C system test program options button was
disabled).
If the I2C system test passes, then only a PASS message will appear. If the test failed, then a
dialog box like Figure 9 will appear. See Section 9, Troubleshooting, for details on how to
resolve this issue.
The I2C system test can be run at anytime by clicking Run System I2C Test in the Tools menu.

8.4 Real-Time Polling Real-time polling provides polling functions that execute in the background continuously, when
enabled via the Real-Time Polling dialog. There are two polling functions. The function that
applies to the TVP5160 decoder is VIDEO–STANDARD AUTO–SWITCH POLLING.
When the TVP5160 decoder detects a change in the input video standard, it automatically
switches to operation in the detected standard (which includes all necessary I2C register
initialization) for proper decoding of the input video. The ADV7311 encoder does not have this
feature. For this reason WinVCC4 must update the video encoder.
