OTA signal quality (audio and video)

I've been playing around with over the air HD broadcasts lately. I've been told its the best quality picture you are going to get next to Blu-ray. But are there degrees of quality based on signal strength or is the signal merely there or not?

Because the picture looks great when the image is relatively still. But I'm getting significant macro-blocking (1/2" blocks on a 46" TV) during scenes with lots of movement. (I don't get these from Blu-ray discs so its not the TV). Would a better antennae make a difference or is this the best that you can hope for with OTA HD broadcasts?

I've also noticed that the broadcast 5.1 audio often has pretty noticeable artifacting (especially in the surrounds). It's a slippery, phase-shifting digital white noise like sound you get when an audio signal is way over compressed). If the video can be improved by a better antenna (outdoor... I'm using indoor rabbit ears now) I'm guessing the audio will improve as well.

Outdoor antenna a must

You can eliminate a great deal of the issues you describe by 1) Moving your location closer to the source transmission, 2) increasing your line of sight, and 3) Relying on a stable outdoor antenna that is not impeded by landscaping/trees or other solid objects. 'Get it done', as they sometimes say Wink

so its not really all or nothing then

stronger signal means higher higher bitrate?

If anything, perhaps a less variable bit rate

I thought the 'cliff effect' with digital was the real problem with obtaining good reception OTA. At least with the good 'ol days of analog I could still identify the sports teams by jersey, although it looked like they were playing in a snowstorm Wink.

OTA

You need something besides rabbit ears as you must be close to signal source. I suggest you go to this site,http://www.avsforum.com/avs-vb/showthread.php?t=381623&page=364 and get your tvfool report and post it so others can analyze it. I use OTA but have large antenna to receive signals from a long distance: 40 plus miles.
