    I think that anyone would be hard pressed to design a digital tv standard that supported efficient video forward error correction and interlacing without hitting the patent thicket that the companies designing MPEG-2 created. As I understand this OMS gets around this by basically supporting neither (which is quite acceptable for video for computer screens that is using a reliable transport). That said the ATSC probably could have used technology that had less patents and patents that expired sooner.

    I agree with you that interlacing is not needed for new implementations. I also agree with you that it probably is possible to implement a royalty free digital tv standard with interlacing and forward error correction. I think it would be very expensive to patent clear it. For example, MPEG-1 video at least has age on its side, and Wikipedia, Redhat and Ubuntu don’t consider it clear enough of patents to support it.
