5.1 Dolby from Over-the-air Broadcasts?
Question:
My question is, i know not all HD programming probably is in 5.1 Dolby surround. And i know that they say some HD programming fom Cable/Satellite providers is in surround sound(w/ and STB). I'm wondering, are some Over-the-air broadcasts also in 5.1 Dolby as well... even though it's terrestrial(O.V.A.)? Like the Primetime shows on NBC or CBS that are in HD... I've seen them say at the beginning "Availible in HD/5.1".
The other thing that makes me ask this, is because HDTVs with digital tuners in them(ATSC) most likely have digital audio out; optical or coaxial...
Answer:
The outputs will vary between different sets. 5.1 is the standard audio signal for HD on both satellite and terrestrial signals. If for some reason it is different, your audio system should automatically make the appropriate adjustments.
You ask many different questions
First lets start with HD TV's without ATSC tuners in them
If you tune to station with Dolby broadcast and connect your
monitor audio (red and white RCA's) to a surround sound
better TV's like a Hitachi will have Dolby present
Now for HDTV's with ATSC built in
the DOLBY is ONLY found on the ATSC audio output
meaning if it isnt digital TV its in stereo
the Dolby surround is not reproduced by the TV
that requires a minimum of 5 speakers
but is available
Almost all Terrestial HDTV programming is in surround mode
however not all programming on HDTV channels is in HD
Also in regards to your change to Satellite TV
Many installers like to "USE" the existing coax
lines from the cable install to speed things up
INSIST on new lines from the dish to each reciever
this will provide the best possible picture quality
guarenteeing no splices or barrel slices
and with the leftover RF coax already inplace
you can set one SD reciever to RF 3 and one to RF 4
and feed them into the coax for your present cable
and aquire PIP from satelite service in other rooms
