Well, H.264 over DMB requires far more processing for decoding that HE
AAC or AAC over DMB or DABv2 (DABv2 is virtually identical to DMB), so
if you're admitting that DMB doesn't work then please go ahead and say
this.

As it is, both Radioscape and Frontier-Silicon have designed
chipsets/modules that can decode video over DMB, so I suggest you go
back to your drawing board and fabricate something else that might have
a grain of truth in it.
