i have now had my fox sat box for about 2 weeks and when i start to watch bbc hd the screen goes green after 40 secs,its only does it with bbc hd and not bbc one hd or itv hd,i have reset the box back to Factory setting and it still does not help and i have played about with the v format but the screen still stays green. i have used other hdmi cable but that does not help
thanks for any help guys

It's almost certainly a fault with your TV. Some older TVs (ie over 1 year old!) as well as some cheap models like Technika don't fully interface with the handshaking routine used by Humax. It's not Humax's fault - they're using a recognised routine.

i was thinking that it an old hitachi 32ld7200a going to take the fox sat box to m8s just to make sure,but i emailed humax they said it could be tv

You may find it better setting the HDR to output a constant 1080I - that way no switching.

I'm frankly sick of Humax blaming the TV manufacturers. I've now heard of 4 different brands of TVs having this "problem". It's clear that, if it is the TV manufacturers' fault, it's obviously a common one so should be worked around by Humax anyway.

I'll repeat what I said earlier - it's the fault of the TV, not Humax. HDMI uses a handshaking routine called HDCP (High-bandwidth Digital Content Protection). Humax conforms precisely to that standard but not all so-called 'HD-ready' TVs do.

Why should Humax reduce its adherence to a published standard just because some TV manufacturers can't be bothered?

:WHS: I get the same issue with my HDMI switch.... just switch it back to another source and back again and its fine....

I have the Humax HDR-FOX T2 (freeview PVR) and the FOXSAT-HDR (freesat PVR) both connected to my Panasonic.

In my experience I have never had a green screen or any problems with the HDR-FOX T2 however the FOXSAT-HDR on average green-screen's about once a week (and then a quick channel hop brings the picture back).

Now as Panasonic are one of the founders of HDMI I would expect them to implement and conform to the standards 100%.

The only real annoyance about Humax boxes are the fact that you have to connect them to non-switching HDMI ports as when in standby and they switch themselves on to record a scheduled program they automatically switch the TV to that HDMI input and you are presented with a black screen (according to other posters they do this with the SCART as well - swicthing pin 8 high so the TV automatically switches). Very annoying which is why I have mine connected to HDMI 2 and 3

It's not just some "'HD-ready' TVs", it's the top-of-the-range Full HD Panasonic G20s, for example.

It doesn't matter whether the standard is implemented correctly or not. If a large number of manufacturers have misinterpreted the standard (which I don't believe - have you any proof that the PVR is implementing it correctly?), things should work around it. If it was something else like free software, or a website, for instance, it wouldn't matter as much, but for devices amounting potentially to over £1000, I think it's honestly ridiculous.

Yep, I have the G20 and find exactly this green screen problem with my FOXSAT-HDR on switching. A channel hop usually brings the picture back but it is an annoyance and it does appear that the Humax is the common denominator...

I get this on my G20 too, though *only* ever after switching from my HTPC on HDMI2. The Humax is on HDMI1.

There are 5 versions of HDCP and some known problems with the standard.

Quote from WikipediA

"Problems
HDCP can cause problems for users who want to connect multiple screens to a device; for example, a bar with several televisions connected to one satellite receiver. HDCP devices can create multiple keys, allowing each screen to operate, but the number varies from device to device; e.g., a Dish or Sky satellite receiver can generate 16 keys.[23] The technology sometimes causes handshaking problems where devices cannot establish a connection, especially with older high-definition displays.[24][25][26]

Edward Felten wrote "the main practical effect of HDCP has been to create one more way in which your electronics could fail to work properly with your TV," and concluded in the aftermath of the master key fiasco that HDCP has been "less a security system than a tool for shaping the consumer electronics market"

Ah, it uses High Definition Convenience Prevention - that explains a lot...

Seriously, WTF? Why does a device that receives only FTA channels need this?

The only issue I get with my G20 is when the HDR comes out of standby to record; screen goes blank. HDR connected to HDMI 1.

I see in a current major Mag that HDMI is often a problem in it's own right..

"So what problems does HDMI regularly encounter? "Many problems have nothing to do with high-speed video," says Jeff. "The majority are issues with I2C, the serial protocol used on the DDC line for EDID (Plug and Play) and HDCP (high Bandwidth Digital content Protection)."The article then describes minute capacitance unbalances ruining the transmission path..

Yeah, it happens when you try to take it out of standby when it's in "medium-power" mode, when it's getting ready to record/recording, for me.

I have started to get this green screen at least once an evening. I've had the foxsat for over two years and it is connected to an Onkyo A/V receiver. The problem has only started to occur in the last couple of months. It happens within the first hour of watching TV in the evening, and the only way I can get the program back is to un-plug and replug the hdmi cable at the foxsat end (doing the same at the Onkyo end sometimes works), Changing channels, changing v-format, selecting different inputs to the Onkyo and switching back again does not fix it. Once I have got the signal back (it can take three or four unplug/replugs to do this) it's fine for the rest of the evening.

So far Humax's help has been to suggest I switch off the foxsat and Onkyo for a couple of minutes then switch them back on. A great way to watch a thrilling drama!

I have other hdmi/hdcp devices connected to the Onkyo, none of which have a problem. I've swapped the inputs around on the Onkyo and swapped hdmi cables, but it's still only the foxsat that green screens.

Is there possibly a faulty component, or is this all firmware? If it is all in firmware, and others are suffering the same problem, surely Humax could fix it. Is everybody else reporting the problem to Humax?

You may find it's to do with the broadcasters being a bit funny about copying HD programming (even though it is free to air).

Try copying a HD recording off your hard drive and playing it on a laptop, or even a different Humax.

Possibly.

I am aware of the fact that it doesn't work - but the fact remains that you can simply use a FTA satellite PVR, PC card or non-Freesat mode on the SAME receiver...

I thought the question was:


Hence my comment about why the broadcasters are using (admittedly half-baked) copy protection

The freesat spec includes this option - if the broadcaster sets optional flags then either the recording will be encrypted or it will will have a limit on the number of copies that can be made.

Some 4 months ago I replaced my LG TV with the Panasonic V20.With the LG, the green screen syndrome was a regular occurance.Since installing the Panasonic,connected to my Foxsat HDR I have not had the green screen once!!

I sometimes get the green screen during the wake-up before a planned recording. iIt's easily coped with.

Last evening its nature was rather odd, a big black area down centre of screen with green both sides with several horizontal black bands. It was easily cured, but does the oddness have any significance?

I had the problem of green screen back in 2006 (pre Freesat) with a Philips HD TV (32PF9731 model later withdrawn because of firmware problems) and a Pace DS910XE. On one occasion a Philips trained engineer who had come to look at the set said the problem could be resolved (by the manufacturers) by blanking out the screen whilst the HDMI handshaking was being performed. That would seem to confirm that it is the TVs that are the problem, not Humax. My current Sony Bravia KDL-40WE5 fortunately has no such problem.
