Re: Screen shots from JAG

OK, but what is the bit rate of the transmission standard? HDTV is about 16Mbps isn't it? Here (no idea about the US) I believe a digital TV channel is about 25Mbps and is used to transmit a single HDTV stream at about 16-18Mbps and a SDTV stream at about 6-8Mbps, plus a few content other feeds like tv programs channels etc.

All which would mean there is more compression in the transmission than the origonal capture would it not? I've certainly seen native Z1 frame captures without any visible macroblock structure like the ones in your posted frames.

Perhaps if Jody had access to native frame captures from the cameras RAW footage a real frame comparison could be made with much more meaning.
