It is interesting to note that one of the problems with the C30 was that they couldn't get it to pass Energy Star:

[An interesting history lesson on DIRECTV's RVU plans if you're not concerned about power consumption.]

Remember that the C31 uses the same power adapter as the H25. I would imagine that a significant portion of the power consumed is in the DECA transceiver section.


Why bring up a box that never made it to customer release, or you just like to spout BS?

If you did a search before providing your insight you might find http://calplug.uci.e...bruary 2012.pdf , which goes over DIRECTV Energy Star participation. It says the power on usage of the H25 is 11.2 watts, the prototype of the C31 is 5.7 watts. Also the training documentation for the C31 says it Energy Star compliant.

As a Dish customer do you have documentation on the Hopper/Joey hardware and is it energy star compliant

See post My Setup for configuration info.

I don't think it's fair to speculate on unreleased hardware and why it remained unreleased, unless it's possible to be completely clear on the facts. Doing so only serves to bait those who could answer but contractually are bound not to.

Would have been real slick if they could have gotten the C31 to run on less than 2.5W, so they could be powered off a TVs USB port (since most newer TVs have one). That would have meant no more power brick.


Yeah, I was hoping for that too. Of course, I also think the thing is still larger than I was expecting... Yes, I was expecting it to be the size of a roku or apple tv, or even smaller than that if possible. Maybe the next generation will be.

Who cares? What's important is what the c31 can do and is rated at and how much power it takes, which is very little, half a h25 and at least six times less than a DVR.

I can see me replacing my HR23/HR24 system with the HR34/C31 when one of the HRs dies. And if I read this thread correctly, my cost to DirecTV may actually drop by $3. This is the Whole Home fee I currently pay, or does this fee still exist? Sorry if I missed this when scanning this thread.

If you don't want WHDVR service anymore for any of your STB's then yes you could drop it, AFAIK the HR34/C31 don't need it. But if you still have a HR2X in the mix and want to share recordings then yes you'd still need the $3 fee.

As DECA alone consumes upwards of 3 watts, USB supplied power was never a reasonable expectation.

Thanks. That's what I assumed. I may have to have the HRs on the account for awhile in order to watch the recordings. But, this won't be happening any time soon as both HRs are working quite well.

The power consumption of an external DECA is irrelevant to the power consumption of an internal MoCA switch chip, which is what the C31 has.

Good point. It does actually make me wonder why they don't make it so can power it via USB. Could be that tvs may not send power to USB when off, so you'd have to wait for it to boot up every time?

Might also be because it needs 12 volts. ;) [haven't checked to know]

Anyone in Houston have this yet, I would love to get rid of this hr22 I am using as a whole home viewer with my hr34, I don't record anything on it.

IIRC I didn't see Houston mentioned as an early test market, but the rumor is that things will open up in October so just hand in there.

The power consumption of an external DECA is irrelevant to the power consumption of an internal MoCA switch chip, which is what the C31 has.

It isn't irrelevant as it is indicative of how much power is required to convert MoCA (RF) to digital which is uniquely the DECA adapter does. The DECA adapter takes the relatively small extra step of converting to current loop that requires considerably less than 1 watt.

If we use an AppleTV as a benchmark (with similar functionality and Bluetooth remote control), it consumes 2.47 watts (2.05 with 83% power supply efficiency while streaming an HD movie) and the C31 consumes 5.7 watts, we deduce that the MoCA part of the equation must be over 3 watts. This is consistent with the power consumption of the DECA adapter and probably why DIRECTV doesn't foresee being able to get below 5 watts on the RVU client.

It is notable that the AppleTV provides either Wi-fi or 100baseTX within its 2.47 watt total.

The input power is specified the same as the output of the EPS10: 12VDC@1.5 amps.

DIRECTV's future power consumption projections remain at 5 watts so the minimum current required at 5VDC will remain >=1 amp.

Because the typical maximum USB current (if any) is 500ma (and you'll never justify to someone that the USB port on their Xbox/PS3/AVR/USB hub is any different than the one on their TV), USB should not be used to provide power for a DIRECTV RVU client box.

That the C31 includes a USB port makes it obvious that it can't draw from USB.

If you don't want WHDVR service anymore for any of your STB's then yes you could drop it, AFAIK the HR34/C31 don't need it.

It would appear that the current ELA doesn't discriminate on whether or not you have the capability of utilizing WHDS.

If you selected an HD DVR, you agree to pay a monthly Advanced Receiver fee ($20/mo.).

The assumption is that if you have only a lone HR2x or HR3x, you must pay the $20 fee.

Based on the most sophisticated box in your setup:
Advanced Receiver fee (one or more HD DVRs)  $20
Advanced Receiver - HD fee (H2x)             $10
Advanced Receiver - DVR fee (SD DVR)          $8
Advanced Receiver - TiVo fee (THR-22)         $5 (in addition to the $20 fee)
The DIRECTV sign-up application confirms this fee schedule. If you select only an HR34, it will show the $20 fee (less a $10 discount for 24 months).

Max ratings mean little.

They mean a whole lot if they get down below 2.5 watts (which may be possible without DECA).

The C31 max wattage is listed as 10.5

As long as the DIRECTV RVU client box max current rating is greater than 2.5 watts, it will be too much for USB to power.

The ARS fee includes the HD fee [$10], the DVR fee [$8], & the MRV fee [$3].
$20 is a one dollar savings over having them separate line items.

The point is that using an HR34 with RVU clients (whether the C31 or otherwise) doesn't save on monthly fees versus a WHDS system as was suggested might be the case.
