Note: Please note that any change in the captured frame (e.g. clock) will result as a failed test.
Test sets available in the CRC based video test set are
• CRC Based Single Reference Frame Video Test
• CRC Based Single Frame Video Stability Test
• CRC Based Sequence of Reference Frames video Test
• CRC Based Continuous Sequence of Reference Frames Test
CRC Based Single Reference Frame Video Test
The test compares captured frames to a provided reference.
TE compares the video mode (Frame Width, Height, BPP and optionally Frame rate) to
provided parameters and after that captures frames and compares the CRC (check sum) of
their three color components to the provided reference until the number of bad frame limit
provided is detected or the provided total number of frames is reached.
The test is judged FAIL if video mode does not match or the number of bad frames is
exceeded.
The test optionally captures the failed frames as bitmap images and stores them into the
hard disc.
