End-to-end safety mechanism for display system

A display system, comprising:

• a display receiving device comprising a screen and a first display port coupled with the screen;
• and
• a display transmitting device comprising a display controller and a second display port coupled with the display controller and the second display port, wherein the display controller is configured to:
• replace one or more video frames from one or more input video streams with a set of alpha-blended test frames, each alpha-blended test frame generated by deterministically alpha-blending at least a portion of a set of test frames with at least a portion of the one or more input video streams;
• generate and insert cyclic redundancy check information for the set of alpha-blended test frames into one or more secondary data packets associated with an alpha-blended video stream;
• process the set of test frames and the one or more video frames to generate an output video stream;
• and
• perform an error detection procedure for the set of test frames using the cyclic redundancy check information to detect an error associated with video frames of the output video stream.

An apparatus for a display transmitting device, comprising:

• a display port;
• a display controller coupled with the display port;
• and
• a processor and a memory, wherein the memory stores instructions that when executed by the processor causes the apparatus to:
• generate cyclic redundancy check information for a set of alpha-blended test frames, each alpha-blended test frame generated by deterministically alpha-blending at least a portion of a set of test frames with at least a portion of one or more input video streams;
• insert the cyclic redundancy check information into one or more secondary data packets associated with an alpha-blended video stream;
• process, by the display controller, the set of test frames and the set of video frames associated with the alpha-blended test frames to generate an output video stream to be output from the display port;
• and
• perform an error detection procedure for the set of test frames using the cyclic redundancy check information to detect an error associated with video frames of the output video stream.
