Pixilization on non hd channels with hdmi cable connected to HDPVR receive. HD channels come in crystal clear, non hd channels are all bitmapped and horrible

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.

You may be able the settings of your directTV box to stop frustrating you. If you help me identify the model you are using, I can research the proper menu choices you will need to choose to select the correct features. There are many different directTV set-top boxes available.

My own home theater setup did the same thing, and my solution was to use component cables from the PVR instead of HDMI cables. It is too bad your blu-ray doesn't allow for this configuration.

My work-around until I realized that using different interconnects fixed the problem, was to turn the TV off and then on again whenever switching from HD to non-HD sources. This fixed my problem, maybe it will fix yours.

I hope that helps.

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

This is a cable box problem. Could be a lack of signal stregnth or bad HDMI output.

The SA boxes have a very bad history of this, try using the component video output and see if the problem persists.

The HDMI is a real glass jaw of those boxes; but this problem could absolutly be your incoming signal...high def channels require more signal strength and that is what causes audio drops, pixilation and flicker.

If it was the HDMI in the receiver/tv you would get:

- Black screen, Pink fuzz or green streak dropouts.
- "Fireflies"
- Audio cutting in and out
- Not pixilation!

So what is my approach? If the box is rented or under warranty get it replaced. If the problem persists then call your cable company and arrange a service call at their expense.

If the box is not under warrenty go ahead and call the cable company and complain about a poor signal. If the signal is good, use the component video output...it looks almost identical anyway.

Let me know if this helps,

Cheers!

The problem could lie in youir HDMI cable, this is a common issue. if you swap HDMI cables and still have the same problem then bypass your A/v rec and connect your 622 direct to your tv and see if the problem persists, it it does, then your DVR needs to be replaced, you can call dish for addition troubleshooting if it is in fact your DVR.

To get an hd picture you have to use a digital input and this cannot be done by simply turning it to a channel. You need to hook up your HD receiver (box) to your tv using either an HDMI or a Component which will be a cable that looks similar to an rca but there are three of them and the colors are bed blue and green. If there is a red, blue and green on the back of the cable box and the tv hook them together with a component cable and then find the input on your tv that correlates to the compnent connections and then even after all of this you need to be tuned into a channel that is offered in high definition and if you have cable like I do the high definition channel will be a seperate channel from the regular one. Comcast in my area puts the HD's from channels 400-500. For example my espn HD is channel 403 but just regular espn non HD is on channel 27 in my area.

I assume you have cable. The cable HD and digital channels are usually sent in Quadrature Amplitude Modulation (QAM). The cable companies are required to send local channels in the clear but not so for any others. Regular (basic) channels may be clear or scrambled. USA many not be but HBO will be.
So you have 1 of 2 problems: (1) your TV does not do QAM or (2) they have scrambled the channels you want to see. Questions: (1) Have tried direct Over-the-Air (OTA, ATSC) reception for your locals? (2) Can you see the HD local channels on cable? (3) Are you paying for an HD box from the cable company to have the channels decoded? If in doubt contact the cable company.
Current Samsung TVs do do QAM and OTA HD. Alternatives are Dish or Direct to get satellite with an HD receiver using HDMI or 5-cable RCA. Costs are comparable but OTA wins, hands down. -Ken

LCD TV refers to the substance that creates the picture quality (it would be either LCD or Plasma or Tube) and HD refers to a crisp clear picture that can be attained. So your TV is an LCD (Liquid Crystal Display) TV that is capable of receiving and displaying HD (High Definition) Picture.

What you need to check for is whether the TV has a built-in Tuner. This will either be SD (standard definition) TV Tuner or an HD TV Tuner. The box it came in will tell you or you may still have stickers on your TV.

If it has a built-in SD tuner you will be able to pick up HD channels but in a lower quality. In this case you will only need to plug the TV into a Wall-socket antenna or rabbit-ear antenna.

If it has a built-in HD Tuner you will be able to pick up HD Channels in full HD quaility picture. Simply by plugging the TV into a Wall-socket antenna or rabbit-ear antenna.

If your TV does NOT have a built-in TV-Tuner then this TV is clasified as "HD Ready". Which means that you have to purchase a Set Top Box (STB). you can get either HD or SD set top boxes. In this instance you will plug the cable from the wall socket into the STB then from the STB into the TV using either an HDMI cable (as long as your TV has an HDMI input) or through RCA cables which will be coloured Green, Blue and Red (i think red)

By the Way - best picture quality is from a wall-socket antenna.
HDMI = High Definition Multimedia Interface
STB = Set Top Box
High Definiton RCA cables will also be refered to as YPbPr/YCbCr (depending on equipment)
LCD = Liquid Crystal Display (the method used to make the picture on your TV screen)

If you have anymore questions, ask away.

Need more detail - What is your TV source (directv, cable, etc,) Also - how is it connected to the Denon?

if you have a cable box then it is probably the resolution settings in the cable box, what type of cable box do you have
