Should I be receiving surround sound from HD receptions?


I have a Hitachi big screen tv that receives HD reception using uhf antenna. Therefore I have co-ax cable from antenna to tv. How if possible do I get the surround sound to my surround sound receiver?


Can I expect the surround sound quality to be the same or close to the same as a dvd?


Thanks

The answer to your first question is "yes" - you should be receiving digital surround sound from your HD signal.


In order to get it to your receiver you would need to run a connection form the TV to the receiver. It is unlikely that your TV has a digital sound output (although you never know - I am not fully up to speed on TVs nowadays), so you might need to run an analog connection.


There should be audio out connections from the TV - run these into the audio in on your receiver and you should be good to go.


The sound will not be as good as a DVD if you have to use the analog connections because you will lose some quality on the conversion - especially since the digital to analog conversion in being done by your television which is unlikely to have good DACs.


If you want to preserve the digital quality of the sound, (I think) you will need to get a separate HDTV receiver that can pass through the digital sound to your receiver.

Does you TV have a built in ATSC tuner or are you using an external tuner?


If you have a built in tuner in the TV, there will be a digital output on the TV to feed an input on your receiver, if you are using an external ATSC tuner it will have an output to feed your receiver. All of the digital connections I know of are optical, but I am sure there is some TV or tuner out there with a digital coax connection.


The sound will be the same as a DVD, Dolby Digital is what is broadcast with HDTV. Some programs only have DD2.0 and some have 5.1


What model is you Hitachi?


OK I searched some of your other posts and you have a 57s700 with a built in tuner.


In the manual page 9 it says you have an optical out for sound. See this link

Go to page 9 & look at item #9, that is the optical out to connect to your receiver. Make sure the settings on your TV are set to Dolby Digital & NOT to PCM only. that is the only audio connection you need from the tv unless you have a vcr or something else that need 2 chanel sound

The Hitachis I've seen with a built-in ATSC tuner feature a optical digital output. He would run that to his Dolby receiver.

I have a panasonic dvd recorder that I will want to hook up also.


What will be the best method to hook up the TV / DVD Recorder / Receiver?


Antenna to TV to DVD Recorder to Receiver or what?


Thanks

 

[Jordan420]

Do you have cable or only Over the Air TV?

 

[mjones73]

What model DVD burner? Most likely you will want to hook your cable to the TV to take advantage of it's built in tuner then the optical out from the TV to the AV receiver for sound. The DVD burner would hook to the monitor out section of your TV via s-video and rca cables to record sound and video then you'd hook it to the component inputs on your TV run a seperate optical or coax input to the AV receiver (would require a receiver with at least two digital inputs.) to view video and sound.

Right now I only have OTA but I will be adding Satellite in the near future.

Well just hook up the optical out from your TV to the receiver for now, when you switch to sat, you won't want to use the internal tuner in your TV anymore, the D* box will have one built in which will allow you to intergrate the OTA and sat into one guide.

Good advice, except you will need to hook up the analog outputs from your TV to the receiver in order to get audio from analog channels.

I have a hitachi ultravision HD tv and it has an optical output to my receiver for dolby digital, however I think little if any is actually broadcast in dolby digital, everything my receiver gets from the TV shows pro logic.

I do not believe so, the manual linked above states that the optical connection will pass PCM & DD, just as sat boxes, cable boxes & DVD players do. I was incorrect when I said to set it to DD only set it to DD/PCM



With your set up right now I would hook the antenna to the DVD recorder, then to the tv. You would also need to hook composite, s-vid or component to the TV for the picture & optical from the dvd recorder to your receiver.


With the antenna going into the DVD recorder first you would be able to time shift or record TV programs onto the DVD burners hard drive independent of what you are watching on the TV


Hook it up like the diagram on page 5 of the manual.


Here is a link to your DVD recorder on amazon which has a link to the manual about half way down the page

Check the settings in your TV it may be set to PCM only.

Everything broadcst in HD is broadcast in Dolby Digital, either 5.1 or 2.0


And check this thread

There is a ton of incorrect and confused advice being dispensed in this thread. Here's the straight skinny.


The ATSC standard for DTV uses the same Dolby Digital AC3 standard as DVD. It can be anything from 1.0 to 5.1 and you must use either a coaxial or optical connection to your receiver to hear it.


To listen to analog channels (either OTA or on cable) you will have to have the analog outputs of your TV or STB connected. Audio from both analog and digital channels will be output via the analog connectors, but only the digital channels will be output via the digital output.

I find it really hard to believe you'd need to switch audio input sources to watch analog channels the built in tuner in the TV receives, there is no mention of this in the manual. They do make analog to digital convertors, it wouldn't be hard for the TV to convert the analog sound to digital and pipe it out the optical connector if Hitachi included the correct circuitry in the TV.

You are correct the standard allows anything from 1.0 to 5.1

99% of what is broadcsat is either 2.0 or 5.1

I'm not aware of any receivers that do the analog to Dolby Digital conversion. Neither my Sony KD-34XBR960 TV or my Motorola DCT5100 cable box output the audio from analog channels on the digital output. If anyone knows of a receiver that does, I'd like to know about it.

 

[mjones73]

I pretty positive my HTL-HD does, will confirm it when I get home.

 

[Jordan420]

My 2001 RCA TV with a built in RCA DTC100 tuner can also do this , there is an option in the audio menu for auto select where PCM is sent to the receiver for 2 ch audio & DD is sent if there is a DD track.


3 of my Dish network receivers 6000, 501, 721 are only connected to the receiver with an optical connection (no L&R), all play audio from every station analog, digital, OTA.


edited due to not working as the manual indicates it will

I have experimented with every conceivable connection mode between my KD-34XBR960 and there is no way to send the audio from an analog station through the digital audio interface. The instruction manual page you referenced merely says the following, "Because all equipment does not output digital audio, you should also connect the TV's analog audio jacks to the amplifier's analog audio input jacks, as described on page 38."


I have also had no success in getting audio out of the digital output of the DCT5100 when tuned to an analog channel.
