What They Say
Semiengineering.com published an article by Rambus that looked at the topic of the big boost in video transport inside cars and the challenges because cars need to meet strict EMC requirements, cannot be too power hungry and need to meet strict safety standards if they involve safety critical ADAS (advanced driver assistance systems).
VESA DSC and VDC-M have been adopted into the MIPI DSI-2 display interface specification, one of the most widely used embedded display interfaces for mobile, AR/VR, and now automotive applications. Last year, the MIPI Display Working Group conducted a study to show that VDC-M compression was safe to use for automotive applications. The study was published as a whitepaper and concluded that VDC-M compression was visually lossless for automotive use cases, meaning that the test images compressed at a maximum 6:1 compression ratio were indistinguishable from the same images that had not been compressed.
Rambus offers encoder and decoder IP cores supporting the VESA DSC and VDC-M compression standards, as well as a MIPI DSI-2 controller.
What We Think
It hadn’t occurred to me that you would have to safety certify something like DSC! (BR)
