Cable boxes! D: 😱
 
you're surprised?

they're on 24-7

even when you "power" them off, they're still on.

i don't even need to read the article to know this
 
Hmm.. hard to believe.

I have the exact cable box pictured in the article. POS Scientific Atlanta.
 
If they lose power don't they also lose all the cable setting, i.e. TV stations and such? So unplugging them would be an incovenience as you'd have to wait for them to upload all that info

My cable box takes about 15 minutes to boot up if you fully turn it off. Mine runs 24/7 because of that.

Only my mom uses it and only on the weekends. We leave it off most of the time.
The 10 minute boot is not really a huge issue.

In our house its probably the AC. I gotta remember to use the automated system and turn it off during the day when no one is around.
 
Not really a big surprise, especially since a large percentage of them are of the DVR variety. You're essentially running a small computer 24/7 so of course it's going to have one of the larger impacts on your electrical bill.
 
We gotta install microwave ovens
Custom kitchens deliveries
We gotta move these refrigerators
We gotta move these colour TV's

Look a' here
That ain't workin' that's the way you do it
You play the guitar on your MTV

My motorola HD-DVR gave off heat readings somewhere nucular molten magma and the surface temperature of sun. No doubt that thing was consuming an assload of energy sitting there 24 hours a day patiently waiting for my wife's soap opera's and reality TV to come on before it leapt into action.
 
I don't own a cable box, so I never got to try the kill-a-watt on it.
How much kwh does it drain?

Based on others, who have used the kill-a-watt..

"Power Off": 30 watts
Watching TV: 31 watts
Recording TV: 31 watts
Playing back a recorded program: 31 watts
 
What the hell are these things drawing, 100W while not in use?

I thought there was some kind of legislated push to have lower standby power consumption on this kind of device? A lot of devices like this spend a majority of their time sitting around waiting for inputs. Standby power use can't be that difficult to minimize. My air conditioner draws so little power when it's off that my cheap little multimeter can't even detect the current draw on the 120V side, and its circuitry continuously runs an internal oscillator, and the microcontroller always has to be ready to accept inputs from the buttons, the remote, or from its own timer interrupt.

Options:
- Flash memory is dirt-cheap, at least for small amounts of it. I can't imagine that these settings files would require very much space, especially with a bit of basic compression.
- Supercapacitor for memory retention. These aren't terribly expensive either.

I guess they're trying to get the absolute cheapest cost possible though - as evidenced by terrible standby power consumption.


Other question I've got: Why does a set-top box take 10-15 minutes to boot? Is it running a 4200rpm hard drive over an ATA/33 interface, or what's the deal?

No shock. I just have a basic HD satellite box and it runs like a space heater. The DVR ones don't even spin down the hard drives when they're on standby.

At first I was 😱. But then I remembered that with my Verizon DVR, it must be set to continuously record any program you happen to be watching, whether set to record it or not.

I discovered this on my own, just trying the 30 sec back button. It works.

That makes sense to record when you're watching so you can rewind, by why does it need to spin when the TV is off and it's not supposed to be recording anything?

I've always wondered why a cable box needed more time to boot back up than a full computer. It seems like it should almost be an "instant on" kind of thing with maybe a few seconds to a minute tops to synchronize the program guide.

Don't ever get a TiVo. Those things take like 20 minutes to reboot. It's insane...no clue WTF it's doing in that time.

Side question: How much power is required to keep DRAM continuously refreshed? We're talking about a bunch of tiny capacitors and transistors, so I'm thinking it's not going to be a whole lot.
Keep stuff in RAM, spin down the hard drive, and save power. If an input is triggered (user input or a timer), then go to a full readiness mode.

I have a SuddenLink Tivo Premier Box and it drives me up the wall when it freezes and has to be rebooted. Seriously 15-20 minutes to boot? WTF is in that thing that makes it so slow.

Cable and TV DVRs never go into standby, they are ALWAYS recording the current channel, even with the TV off because the DVR isn't off. There is no one or off button for any DVR I've had, including the TiVo unit I have now. All you can do is pull the plug.
 
I work for a cableco and know from experience: Even people who should know better tend to leave the box on when they turn off the TV.

From a product design standpoint, that's really inexcusable. There's no reason it should ever take that long.

If they used laptop components which were designed with lower power consumption in mind I bet they could save quite a bit of power.
 
when I bought my new tivo (upgrading from the series 2) I was a little amazed that it didn't even pretend to have a standby option.

I'm pretty convinced that my old series 2 got trashed because my roommate and I left it running 24/7/365 in a cabinet with poor ventilation.
 
...upon reading his thread, I now know that many ATOTers think the box is off when the TV is off.

...upon reading your posts, you seem to be saying that the article is wrong and turning the box "off" does more than turn off the clock on the front.
