I use HDMI output to TV .....

I have only had my iView for a few days (v7 firmware) and I also use the HDMI output to the TV. I see occasional 'dropouts' (screen goes black for a second or so) do you also see this? What version of firmware are you using?

Thanks

From the posts of this thread and what iView said, I guess it'd be mid Sept the earliest.

I have had issues too with the HDMI and switched to component and all is well so far. I think if you install V3 firmware you might get better results. I wonder if the issue is with IVIEW or possibly the HDMI cable being used. There are differences in HDMI cable quality and standards. It may matter to the IVIEW:

If anyone has done a comparison, either between the analog vs. dig outs of this unit, or else between the analog outs of this unit and another tuner box (like my Insignia or Zenith standard def boxes...sorry, don't know the models offhand, bought them when the U.S. first switched to digital broadcasts) I'd be interested in what you've found.

I use component video with the RCA audio jacks and see (hear) no bass issues.

A very dumb question
I have to ask a really dumb question (especially since I am an electronic engineer with 30 years experience and have flashed many firmware updates)mad.gif. Anyhow, I can't flash the iView. I tried a 128 MB FAT formatted USB and also a 32 GB NTFS formatted USB and neither one was a happy ending. Any facts that will pull me so I point North again would be appreciated.

I don't own one of these, but it seems I remember that it must be formatted Fat-32.

It must be FAT32 formatted to flash. What exact problem are you experiencing?
post #1808 of 3145
Just received my second unit and externally from the remote to the box it looks the same.

Next up will be to hook it up and see what firmware I see.

Neither the FAT or NTFS formatted USB BIN data is recognized which is surprising since both file names are recognized. It sounds like FAT32 is the requirement - using FAT you can tell I'm "old school".

Thanks

It's in the manual. From the various threads I follow on this forum, I apparently am among the 0.0001 percent who read manuals.

It's good you do. I did a search for "FAT" in the manual with no hits - on second look, the FAT32 info seems to be embedded in a non editable/searchable format.

Thanks for pointing me North !!!

Amazing what happens when you RTFM !!!

I did some more testing, connect both HDMI and A/V to Yamaha pre-amp. Then turn on some Spanish POP or Korean POP channel. Switch the audio between HDMI and A/V to compare the
POP music base frequency. A/V does missing the deep base and sound a lot thinner than HDMI output sound. A/V is not HIFI sound. HDMI is a lot does sound a lot musical.

I noticed the same thing on my DirecTV HD receiver, the sound from HDMI was always fuller and had better dynamic range than the sound from analog left & right output. It should be that way.

My new unit came with V3 firmware installed. I have connected it via HDMI and set up recordings for this afternoon. I'll report how it went later.

Ok thanks very much for that info, that's exactly what I was hoping to find out! For whatever reason, they must have put a high pass filter on the analog audio outputs. Kind of a shame, since some people are limited to using only those outputs (and the analog outs on my old standard def tuner boxes sound awesome, I'd think any new box would be at least as good as an old, budget priced standard def box). Anyway, now I know when I get my new receiver, with dig. audio in, I'll be back to full-range sound. Thanks again for checking that out and chiming in with what you noticed!

Analog audio has been capable of extremely high fidelity for many many years.

To me both HmWrx 150 and IV3500 is pretty much the same stability. May have difference issue
For HmWrx150, I have not seen "No signal". Occasionally when playback record program, It will hung at certain point, have to power down
and power up to reset. When play back to that hung point, will hung again, have to fast foward pass hung point and will continue play normal.
Another issue, if you hit too many key in the remote before waiting for the currect one finish. Will also hung it. Have to do power down and power up.

Both IV3500 and HmWrx 150 have mischief behavior. I read through other DVR forum, look like everyone has some type of this miner issue or not perfect issue. 99% Daily/weekly recording is working.

This morning I do experience "No Signal". Look like this is the first time happened to me since update to V3 on 8/7/2013. I have not seen this issue on HW150 yet!

Agree! You get stereo and there is Nothing wrong with stereo. Some of us even remember when it was state of the art!

You need to make sure your HDMI cables are HDMI 1.3 compliant. That is the standard that IVIEW is using for HDMI. Does it make a difference? I really don't know but it might be the culprit. An expert on HDMI can chime in.

I know the HDMI cables I am using are cheap (budget) and go back a few years. So I suspect that might be an issue with my equipment.

I suspect what Leo King meant by "It should be that way" is that since it's the same way on his DirectTV box, that my iview unit is most likely not defective, rather designers of these things just tend to design that way.

Now, WHY a designer would choose to do that....that is a puzzler. Only thing I can think of (knowing a little about electronics) is that the wrong value capacitor was used to block DC going into the analog outputs' op amp. If you use the wrong value cap for that, it can filter out the low end. So it might just be an accident. If anyone can get hold of a schematic, it would be easy to see if that were the case.

Would be nice if iview would take notice of these posts and offer an explanation.

Yep, HDMI is capable of transferring much better high fidelity sound than the L&R analog audio input/output. Because people often connect the HDMI output on the video/audio components to their receivers, the video/audio makers let the HDMI ports transfer the sound in the uncompressed digital PCM or RAW form and let the receivers do the conversion of the audio to analog signal. The audio from the L&R analog output on the other hand is in the compressed form. That's the reason the sound from the HDMI output sounds more punchy than the sound from the L&R output.

Wow. I didn't realize that every device every built with Red/Wht analog inputs had the smarts to uncompress this "compressed" signal. eek.gif

Thanks Johnnyw2, for confirming that this is not related to the HDMI output. I just can't see how the output being HDMI, composite or component would have any effect on the incoming RF signal or how that signal is being processed. I believe that there is something else going on. Could have something to do with firmware because some claim to not have this problem with the HmWrx STB. I do know this... the couple of times I have seen the "No Signal" error was only when I first turned on the 3500. Then in order to correct this error, I had to completely power down the 3500 by un-pluging it from the AC Outlet. I have not seen this error occur while the 3500 was already powered ON. Again, in my experience only after first turning the unit ON. Any one with different experiences???

If this can be shown to be a Firmware related problem then iView should be made aware of this. Especially since the only way to recover from this problem is to un-plug the STB from the AC outlet. The difference I see between the 3500 and the HmWrx STB's is that on the HmWrx the On/Off button on the case powers down the actual Power Supply board, While with the 3500 the On/Off button turns off or places the main board in a state of "stand-by".

Perhaps Evelyn or somebody else from iView would like to comment on this "No Signal" Error.

Not every audio component that has the RED/WHITE audio output is that smart.

Now in video/audio application, the RED/WHITE analog audio connection doesn't have enough bandwidth to handle uncompressed multichannel audio even when the multichannel audio has been mixed down to stereo and, therefore, the audio on the RED/WHITE output can't be in the uncompressed PCM form. When we compress a CD audio track to MP3, for example, we will notice the bass (low frequency sound) suffers the most.
post #1826 of 3145
Nickle2,

When I had this problem all I did was use the remote to turn the IVIEW off and then almost immediately back on and the signal was there. Maybe 2 different issues?

The audio on the Red/Wht analog connection can't be PCM because PCM is digital. If what you're saying is that iView is taking the audio from the digital broadcast and doing a poor job of converting the signal to analog to output via the Red/Wht connection we can agree on that. But to say that the Red/Wht inputs on audio devices can't handle quality sound (punchy as you call it) is just not correct.
post #1828 of 3145
I was not saying the RED & WHITE audio output can't handle high qual sound. What I said was in the AV application, it just can't deliver as good a sound as the HDMI because of the limited bandwidth it can handle (and therefore it can't transmit PCM).

We'll have to agree to disagree. smile.gif

QAM and ATSC television deliver audio in AC3 (aka Dolby Digital) audio. It is digital.

Digital audio formats such as DD, DTS and PCM can be sent over an RCA cable IF it is the digital coax connector. This is different than the Left/Right (Red/White) connections.

Analog audio sent over RCA cables can be very high quality. It's why early (and current high end) Blu-ray players use the format for 5.1 and 7.1 analog connections to tuners (using 6 and 8 cables respectively instead of 2). One wire for each speaker's signal.

BUT, and here is the problem, digital audio MUST be converted to analog in order to pass it over the L/R cables. This requires digital to analog converter chips.
Cheap DACs found in cheap hardware will sound cheap. Good DACs are found in expensive hardware.
So while the connectors and cables are capable of passing good audio, the manufacturer of iView boxes will not have spent the money on high end DACs (if they had, you'd be paying more).

You would do better using the Digital Coaxial or HDMI output, and passing the audio to your AV receiver, which in all likelihood will do the job much better.

To be further clear. There is no bandwidth on analog cabling. That is a digital concept. It's only limitation is that the signal can only represent one channel of sound.
Digital coaxial has the same bandwidth limitations as optical audio connectors which is pretty much higher than DVD specs.

HDMI only improves on other digital cabling by allowing more than 6 channels and Dolby Digital TrueHD and DTS-MA HD. No of this means a damn thing to an iView.
