Are normal HDTV shows just stereo or is there some surround sound encoding?

post #1 of 5
Thread Starter 
I am an old Audio hi fi buff but completely new to Home theatre. I finally got rid of my old refrigerator size rear projection tv and bought a 70" sharp LCD/LED and Onkyo reciever. When I watch movies the jacket always tells how the sound track is encoded and I set my reciever to the appropriate decoder,

However, I mostly just watch HDTV on u-verse. I don't find any information on the channel guide of any type of sound encodeing for TV shows or movies. Should I assume they are all just stereo? And if so is there a prefered setting to give a surround sound effect?

I would say almost all are DD 5.1. But thats for my viewing habits on Comcast cable.


Your experience may be completely different on U-verse with the shows that you watch.

I would use auto surround in which if program is stereo that's what you'll get. If 5.1 that's what you'll get assuming you have that setup

Most HD content is 5.1, but some (mostly older) shows are 2.0, Your AVR should know what signal it's receiving and set the appropriate surround mode. If not, you can always check your AVRs front or on screen display to find out what signal you are getting.

That being said, in my experience most 5.1 encoding for television shows is implemented terribly. This is why I've set my DirecTV Tivo to only output in stereo and I let the AVR matrix from there. Everything sounds better this way to me.

I agree most HD is 5.1 although the surrounds may not be used much. I use PLIIx for my TV and Blu-ray listening, this gives me 7.1 output even if the source is only 2.0 or 5.1. So I enjoy 7.1 for basically everything and I love it.
