Abstract: Some examples described herein provide for display image data reliability and safety, for example end-to-end safety methods, apparatuses, and systems for display systems. One example includes a method, including replacing video frames from input video streams with a set of test frames. The method further includes generating an alpha-blended video stream based on the set of test frames and the input video streams. The method further includes generating and inserting cyclic redundancy check (CRC) information for the set of test frames into secondary data packets associated with the alpha-blended video stream. The method further includes processing the set of test frames and video frames by a display controller to generate an output video stream. The method further includes performing an error detection procedure for the set of test frames using the CRC information to detect an error associated with the set of video frames.
