Hi, I am in Melbourne Australia. Can I receive gem hd channel thru my dmr-ez48v. I haven't tried but I do have a hd monitor screen that I can plug the unit into. Also what does the hdmi on the unit do....


HDMI means high definition multimedia interface.

When connected to an HDMI compatible unit, an uncompressed digital audio and video signal is transmitted, enabling you to enjoy high quality digital video and audio with just one cable. When connecting to an HDMIcompatible HDTV, the output can be switched to 1080p, 1080i or 720p HD video.

Panasonic uses Viera link option between their video products.

When connecting with a Panasonic TV (VIERA) or a receiver equipped with 'HDAVI Control' function, linked operations are possible. [Linked Operations with the TV (VIERA LinkTM HDAVI ControlTM)]

Please use HIGH SPEED HDMI cables that have the HDMI logo (as shown on the cover).
It is recommended that you use Panasonic's HDMI cable.
Recommended part number: RP-CDHG10 (1.0 m/3.3 ft.), RP-CDHG15 (1.5 m/4.9 ft.), RP-CDHG20
(2.0 m/6.6 ft.), RP-CDHG30 (3.0 m/9.8 ft.), RP-CDHG50 (5.0 m/16.4 ft.), etc.
Non-HDMI-compliant cables cannot be used.

(the above is from the owner's manual of this model - page 40 tells you about linked operation using HDMI HDAVI control and how to set it up)

As for Gem HD, this unit has an SD (standard definition) digital tuner - it will not decode/receive HD channels. I should point out that 7mate also is a HD channel but is not specified as such in any menu or even their website. (I found this out by accident when I tried to record on timer 7mate one day and all I got was 'unable to decode HD channel' banner at the bottom of a blank screen)

Channel 11 is a SD channel - so this will work with your DMR-EZ48 as will all the other relevant main free to air channels (ABC/7/9/10/SBS). GO! is also a SD channel.

To be able to record HD to this combo unit you will need a HD set top box connected via its AV inputs. HDMI simply means you will get HD video quality from the combo to the TV, you will not receive HD channels from your HDTV to your DMR-EZ48 unit via this method.

Go to the TV setup menu and autodetect all channels. This should fix it. This is assuming your Sister is not using a set-top box.

In that case, you neet to leave the set on either channel 3 or 4, or use the video/audio input jacks and leave the set on VIDEO IN. The best picture with a non-HDMI set-top box will always be with the AV OUT from the box going to AV IN on the set [the white/red (audio left/right) and yellow(video) connections].

If she is using a set-top box with an HDMI output, connect an HDMI cable to the set and select HDMI IN for the absolute best picture.

I can't get all the channels on my set top box.


Thanks for working with me to solve your problem. The reason you cannot watch those channels on this TV is because you are using an incorrect connection between the set-top box and the TV. A co-axial cable cannot carry an HD signal.

You will need to connect your set-top box to your TV with one of the following cable types.

1. HDMI
2. Component A/V
3. S-Video with separate audio cables.

You will need to check which sockets you have available on both the set-top box and the TV to determine which cable you should use.

Following this, you may also need to run the channel scan again. They should already be tuned, but currently you are not able to watch them. The correct channel numbers for these stations will depend on your region.

If you have any questions or need any further assistance, please let me know.

Regards,
BElectric

Audio on some TV channels/shows goes off. It varies by channel, sometimes national feed is silent, but local break-ins have sound. I have to set the Audio from A.F.D. to Movie to get audio. Sometimes I...


Not sure what this means: "The audio comes to the Cable box through coax cable." From where does audio come TO the cable box? The cable box is a source of both audio and video. Perhaps you mean the TV broadcast "containing the audio and video" comes in on coax.

Has this ever worked correctly? <<<<<<<<<<<<<<<<<<<<<<<<

Try this: disconnect the HDMI that goes from the cable box to the Video 2 on the receiver. Leave the optical audio cable in. How's the audio now?

Then try the reverse: reconnect the HDMI and disconnect the optical audio. You shouldn't need BOTH for audio into the receiver.

Now what happens?

I have a Marantz SR5004 AV Surround Receiver. There is an HDMI cable from the cable box to the Marantz and another from the Marantz to a Samsung HDTV. Everything is fine when the cable box is set to an HD...


Hello First off i would determine if the same thing happens when the cable box is connected directly to the TV with the hdmi cable.

If the picture goes out get a new box from your cable company.

If it works fine then its time to call Marantz

My Denon avr 4310 does a similar thing and after a lot of research it seems that the problem is with how digital signals are sent through the HDMI cable and how the control board of your receiver processes those signals.

Here what I mean

HDMI is meant to simplify connections by transmitting video, audio and CONTROL signals through 1 cable.

The problem becomes when you introduce a "middleman" in this case your receiver the control signal doesn't always get interpreted correctly.

My TV has the capability to "turn off" the "control" signal coming through the cable if yours does try that first (i have a sharp 52" led) this solved some of the issues.

My receiver has the capability to accept different inputs and merge them so here is how I get around the problem.

1. I use HDMI for video signal but also use the optical for audio this allows me to send the "complete" hdmi signal through the receiver and to the TV this complicates things but also allows you to get audio through your tv speakers so if you want to watch something late at night you aren't waking people up when the receiver gets loud. This stopped things like the video flickering or turning off.

You will have to play with your menu's to see if you can do this on your unit.

How to fix this easily? Dump HDMI and use component (red, blue green RCA's) for video yes its still HD and yes you will have to run audio separately. but it eliminates all the digital processing issues that receiver manufacturers haven't worked out.

I was pretty upset when I spent $1500 for my Denon receiver and Denon then told me that HDMI doesn't always make anything better.

Hope that helps

I have a Philips DVDR 3575H. using Comcast's


Try this set up-

Use an RCA audio/video cable for this set up (Yellow/Red/White).

Connect from the Video out (Yellow) connection on the back of the cable box to the Video in on the back of the DVR.

Connect the audio (Red/White) cables from audio out connection on the back of the cable box to the "Audio in" on the back of the DVR.

This should still get you a decent picture but not a true HD picture for your recordings.

When you set the timer to record set it to record either E1 or E2 depending on which input you connected the cable box to and ensure that the cable box is tuned to the channel you wish to record.

*** NOTE: If you keep the HDMI cable connected as you have for the cable box and watch normal TV through the HDMI input on the TV you will get HD programming for your general viewing but still have the option to record with the DVR at a lower quality. ***

Good Luck and please rate this solution....

I am about to receive an LG32LF4700 Freesat/HD TV If I disconnect the SKY Box and connect the TV direct to the Dish cable will I receive Freesat HD channels. Also can I connect an extra bedroom TV into the...


Yes you can split the signal out from the back of the Freesat/HD (not the TV)to the second TV.
Look what outputs are on the Freesat box - the RF (standard cable) output should go to the 2nd TV (TV set to CH3) and the a/v cables,HDMI or DVI cable should go to the new TV - Note:To receive HD the output from the Freesat should be either HDMI,DVI or Composite output (RGB video jacks) with red White for audio. If you have HDMI this is best - it also provides audio.

Hdmi and audio


It may be the top of set box.. Most times the sound and picture are auto detected by the set when HDMI is used. Both sound and video are carried in a HDMI cable but not with a S video cable. Try another HDMI cable *** dont buy the expensive one the tv don't care if they cost $125 or $25.

Sony surround sound hookup


In short, the answer is: Hook up all three to each other. I have a Samsung DLP HDTV, and I was trying to hook up a Sony DAV-HDX500 home-theater system and a Comcast HD set-top box, but I found that the Sony user guide is helpful only for setting up the speakers. Most of what it had to say about HDMI and getting the TV sound or cable sound to go through the speaker system was wrong (or, at least, it didn't work for me). So, here's what I did. I connected Component video cables (Y/Pb/Pr out) from the Cable box to the TV (Y/Pb/Pr in), audio cables from the Cable box (audio out) to the Sony system ("SAT/Cable" audio in), and an HDMI cable from the Sony system (HDMI out) to the TV (HDMI in). This allows me to 1) watch DVDs with surround sound through the TV's HDMI source (when the "DVD" format is selected on the Sony system), 2) watch cable with surround sound through the TV's Component source (when the "SAT/Cable" format is selected on the Sony system), and 3) watch cable WITHOUT the surround sound, as I did before I ever had the Sony system. One item of note: When watching a non-HD channel with the surrond sound on, the audio is slightly out of synch with the video; thankfully, there's no such problem on HD channels. Anyway, I hope this helps. It drove me crazy for two days straight!
