[vdr] HDMI-CEC dvbhddevice - TV switches itself on continuously

[Pim Zandbergen]

Hello list,

My VDR box with dvbhddevice is connected through an Onkyo HTX-22D
2.1 home cinema set to my new Samsung UE32D6530 TV.

I enabled HDMI-CEC on both the Samsung and the Onkyo. This works nicely,
the Onkyo automatically switches on and off with the TV, and the Samsung
remote operates on the Onkyo volume.

Now I also need to enable HDMI-CEC in the dvbhddevice. If I don't, my
Onkyo will deselect VDR as an input source after a few seconds, and I have
to manually reselect it using the Onkyo remote.

But if I do enable HDMI-CEC in VDR, I cannot switch off the TV. If I use the
Samsung remote to switch off the TV, both the TV and the Onkyo will
switch off, but both will switch on again after a few seconds. I need to
pull the HDMI plug from my VDR box before I can switch off the TV.

I'm using Fedora 16 x86_64 with VDR 1.7 RPM's from rawhide. I recently
upgraded from 1.7.22 to 1.7.27, because I could see there are new HDMI-CEC
options. The old version just had one option, enable or disable. The new
version
has the extra options to no switch on and off the TV. I have these new
options
set to disabled. Still my TV switches on when connected to VDR.

BTW, it would be cool if "shut down" VDR could be interpreted as
shutdown just
the hardware decoder part on the dvbhddevice, but leave the tuners running.
I don't want my VDR box to be shut down for any reason, but stopping the
hardware
decoder when not viewing could possibly save some power and heat
dissipation.

Thanks,
Pim

Hi Pim, did you update the Firmware as well? If not, please try the

Hi Andreas,

Thanks, I should have thought of that.
I'm currently on 01_v0_3_5. I will try 01_v0_3_8 and let you know.

OK, the release notes for this new firmware specifically mentions this issue
to be fixed and indeed it is. But it seems to break all the good things too.

VDR appears on the Anynet+ menu of the Samsung, now as "VDR" instead of
"TT ST-6400". But it does not respond to it being selected from the source
menu. It says

"Anynet+ device is not connected. Please check connection and retry".

Refreshing the device list appears normal, but does not help.
This did work with the old VDR and firmware.

Also, after switching on the TV, the AV receiver will deselect VDR a few
seconds starting. It selects the optical input used for viewing native TV.
This is exactly what happened with the old VDR/firmware with HDMI-CEC
disabled in VDR.

Thanks,
Pim

BTW, since power consumption and heat seems to concern you, just curious
if you have measured or happen to know how much power your AV receiver
and TV consumes when in standby since you set them up on HDMI-CEC.
AFAIK, most AV receivers suck more than 30-40W just because the HDMI
electronics has to be powered all times in order to have CEC working...

Good point. The IR receivers on the AV receiver and TV are also always on.
Does HDMI-CEC in standby cause so much more power consumption?

Well, seems it does in most AV receiver makes, because the manufacturers
provide them mostly with one single power(ful) supply, there are some
Yamaha models with a separate (low) power supply just for the video
(HDMI-related) circuitry, they can achieve just 2-3W in standby with
HDMI-CEC... Anyway, it's an issue one shouldn't take for granted and
meet with decent skepticism, rather measure at the power outlet in the
given situation. The manufacturers are not likely to specify this in
their data sheets or manuals. Some models allow you to setup HDMI-CEC
only for the ARC from the TV and let power control or HDMI passthrough
disabled. But the latter two are also nice to have, unfortunately they
come at such cost...
