As more hd channels are added and hd becomes the norm , you will see less details and sharpness in the picture and the compression turned up to squeeze more channels in. Then the industry will come out with Super High Definition , requiring everyone to upgrade to it, to get the sharpest picture quality. More $$$$ for the industry. Remember when Satellite tv began in the early to mid 90's? The picture was razor sharp and they advertised "Crystal Clear Digital picture". Then as locals were added and more national channels were added ,the crystal clear picture began to degrade and looked like crap. Case in point Directv's sd picture looks like total crap. DISH has come up with compression techniques that continue to cram more channels into the same transponder and you are supposedly not able to see the channel suffer any picture quality loss. First it was 3 hd channels to a transponder , then 8 and now I am hearing 9 hd channels are being crammed on to one transponder, using mpeg 4 compression. The more hd becomes the normal delivery for most channels , the more you will see the picture quality drop and the average public won't even see the difference. Remember most think that coax cable plugged into the tv is hd ,JUST because the tv is hd . Most don't even know they need hdmi cable to get hd picture.
