Question about Panasonic SC-HT920 System

1 Answer

Does not play multichannel audio (5.1) input through optical digital audio

I have an upscale DVD player, so that I can use the HDMI connection to display upscaled 1080p video from my DVDs to output video to my HDTV. I thought that using the player's digital output to connect it to the Panasonic SC-HT920 digital input would let me have the whole experience of HD video (on the TV) and 5.1 channel audio (through the Pana system), but I was wrong. When I select the 5.1 audio in the DVD an error mesage apear in the front panel of the home theater. If I downgrade the digital output to PCM (instead of bitstream) on the upscale DVD player, everything starts working and I can hear sound, but only stereo (2ch) this time.
Therefore it gave me the hint that it had something to do with the digital audio decoder in the home theater system.
Amazingly, I am able to decode with the SC-HT920 multichannel audio (5.1) that comes from the cable box and see movies that, for example, play on HBO with 5.1 audio.
I have tried every single combination of digital audio settings in the upscale DVD and in the home theater system and nothing made the multichannel audio from the upscale DVD player to be reproduced by the home theater system.
Now I am thinking that there may be some additional layer of protection in the upscale player digital output that prevents the audio being decoded in the SC-HT920.
I am convinced that it should be an internal software issue in the home theater system, that either cannot decode the digital signal that is being input to the unit or prevents the decoding due to some additional layer of protection that is output by the upscale DVD player digital audio output.
If anyone can help me with the solution (or work around) of this problem I will be very thankful

Hi try this.

in the dvd player make sure you just leave it default (bitstream) but in the home theater receiver don't select 5.1 b/c that will only give you a virtual 5.1 not a true 5.1. In fact don't select any sound field at all just select dolby digital or dts depending on the source of the movie then you should be ok.

The only other problem i can see is that hdmi sends both the sound and picture to the tv. You will need to see if there's a function on the dvd player to only send the picture via hdmi and the sound via the optical out of the dvd player.

good luck

I have a 50" Emerson and I want to hook up the Wii system. The problem is that our local cable company is using all the a/v cables available.


You can always get a switcher and select what device goes to the tv without ever changing any cables again.

You seem to be using the Video & Audio connection. Start at the Player. Connect cables to YELLOW Video, RED Right Audio WHITE Left Audio Then go to TV and find the YELLOW input RED input and WHITE input. On some TV's they are separate, some combine them with the COMPONENT inputs (Component is 5 cables you will use 3 of them if you only have COMPONENT inputs)
Some TV's have an input button on the remote but no on screen selection. Try pressing the input repeatedly to access the other inputs. Lastly you will not get upscaling if you are using the 3 cable hook-up. To get upscaling use an HDMI cable to connect. Be sure to not have both types of cables plugged in at the same time HDMI by itself is best. If you reply with the modelof the sanyo TV I'll try to get you more info.

hi,
You have to check the digital audio assignment of you AVR for HDMI 1 and HDMI 2. There is three options for the digital audio for HDMI 1 and HDMI 2. You can set it as optical ,coaxil, or the HDMI itself. In you receiver the assignment may be in optical input or in coaxial input for the two HDMI inputs.

1. Go to the system setup
2. Select input setup
3.Select input assignment.
4. Select all the three input ,you are using as HDMI

ok

How do I go from 480p to 1080dpi on my 65inch HDTV


If you're using an HDMI cable your display will automatically adjust the settings based upon the video source. Make sure that your source is capable of outputting 1080p. If it's an HD Cable Box or DVR, the maximum resolution it can display is 1080i. If you have one of these HD boxes, set it to only display 1080i as there will be a delay every time you change channels from a channel that is not naturally at 1080i.
If your source is a standard DVD player, it can only display images in 480i (or 480p if it is Progressive Scan) and therefore your TV will display the picture in 480 resolution. If your source is an upconverting DVD player it will display up to 1080p however, Keep in mind that DVD's are in 480 resolution and that regardless of upconversion (or upscaling, though improved, the picture will not be in HD.
The only way to achieve a true 1080p (not dpi... that's dots per inch... that's a printer term. The "p" is for Progressive Scan as opposed to an "i" for Interlaced) is from a 1080p source, i.e., a Blu-Ray disc player playing a Blu-Ray Disc with the use of an HDMI cable. Component Cables can achieve 720p/1080i only with your TV as it does not support 1080p over component cables.
As an aside, there are some media players that support 1080p output and some DirecTV Boxes and DVR's d oas well for 1080p Pay Per View movies.

Panasonic DMREX85EBS recorder upscaling problems


Check the HDMI settings and your TV specifications. Press Functions on your remote and go to Display (up/down arrows). Press Enter. Go to Connections and again Enter. Then HDMI settings and Enter. Look for HDMI video settings. If the setting is automatic, the unit sends the output it believes is best for the TV. You will notice that the compatible video outputs are the only ones available for selection. (A new cable may be worth testing.)

I hope this helps.

WHAT ARE THE INPUTS FROM A DVD PLAYER TO THE TELEVISION I AM NOT GETTING AUDIO FROM THE DVD PLAYER TO THE TELEVISION.


Your DVD player may have up to 3, sometimes 4 audio OUTPUTS. Labeled as "bitstream" which is a digital coaxial cable, another labeled as "optical" which is a fiber optic cable. Depending on the model there may also be as many as 2 different types of analog outputs, one is a 2 channel composite connection, or otherwise known as RCA and another is labeled as "multichannel out."
Your television will have audio inputs on the same panel your video cable is connected from the player. Connect to those from the player.

When connecting hdmi out from my panasonic blue-ray player to the dvd input in my yamaha rx-v365 there is not audio or video,why?


There are several video and audio inputs named DVD. For video you have HDMI, component and composite. For audio you have standard analog stereo and digital coaxial spdif input.
You need to configure the receiver to use the correct inputs - that means HDMI and coax. Also you need to connect the BD player via coax spdif cable to the receiver, because rx-v365 doesn't support audio via HDMI. If BD player has only optical output, use DTV/CABL HDMI input and DTv/CABL Optical input on the receiver.
