The Norman Baker TV Standby Mode Challenge
 
Standby modes on consumer electronics are under attack again:

http://news.bbc.co.uk/1/hi/sci/tech/4620350.stm

My problem with this is that I think a lot of the criticism is
justified, but I get really annoyed by exaggerated claims which are
endlessly lapped up by lazy journalists. Take this quote, for example,
from Norman Baker, the Liberal Democrat's environment spokesman,
advocating a "polluter pays" approach to the standby problem:

"In the end, there has to be costs in the form of manufacturers paying
something to recognize the damage they are causing. Some of these
standby modes for televisions use two-thirds of the electricity that it
would if it were on. I think some people think that standby is a tiny
red dot that has no impact at all."

He'll be telling us next that a TV on standby uses *more* power than it
does when it's switched on. Actually that's a claim I've already seen
made, and of course for some values of 'on time' versus 'standby time',
it can actually be true! The question of instantaneous power versus
overall power consumption just gets thrown into the mix without any
comment or qualification.

Anyhow, my challenge to you all is to find a TV with a standby mode as
woefully inefficient as the one which so exercises Mr Baker's vast
political intellect. Name and shame, that's what I say!

Playing devils advocate, can you point me at some official TV specs. (i.e.
off the Sony/Panasonic etc websites) that state how much power is used in
standby mode? I've never spotted them given (unlike some PC monitor
manufacturers).

The set-top box words were interesting though. Bet a set top box does slow
down the processor when "off", even though downloading an update can't be
anything like as arduous as rendering real-time images.

BTW, if you want to see a real power hog, look at the specs. for a Pentium-4
PC. It has a power save mode that can at best be described as "not quite as
bad as the full speed mode but still a small room heater".

The Philips website lists them under "Specifications" for each set.

Most sets appear to be 1W in standby.

This really does wind me up. Standby may use some power, but if you are
going to have a go at people wasting electricity, why not ban excessive
Christmas lights... This year has been by far the worst, with whole streets
seemingly competing with each other to try and blow their local substation.
Now that is a real waste.

Perhaps I'm way off the mark here, but what happens to the "wasted" energy
from TVs on standby? Presumably it is disipated as heat - contributing to
the warming of the room - so the central heating can run that slight bit
less....well in winter at least. The other thing to consider is whether a TV
left on permanent standby is likely to last beyond one which was switched on
and off daily. The effect of continual heating up and cooling down of
soldered joints is well known.

I was talking to someone the other day who was employed to preach the evils
of the standby mode to the good people of Lancashire. She said that the next
target was to actually get people to unplug TVs, computers and the like,
because the power switch on the front is only a low voltage affair requiring
part of the PSU to be powered up to monitor it...

I should add, that I DO power-off my TVs at night.

Lol, what a nice little technically illiterate world they inhabit, if only
we just switched the TV off in the evening and planted a few windmills in
the ground and covered our tiles a 80w solar panel then everything would be
just fine... we could decommission 40% of our generating capacity and
neglect to replace it with anything but the said windmills and everything
would be happy clappy... don't you see? You must be stupid if you cannot get
your head round simple logic like that!

I don't seriously believe we will address this problem in a realistic
fashion until the lights go out, only then will these foolish notions be
cast aside in the cold light of day.

Quite useful as at the last count there are eleven standby items in one room

Saw one similar in one of these "offer" magazines that comes with the Sun
or News of the World, but with the tv supposedly on the "control" socket so
everything else switches off when the tv is switched off.

Ideal I'm sure for video recorders, Sky+, PVRs, etc etc :-)

Bet there will be people rushing out to buy it without thinking through the

It's a STB. If you put it into standby you just turn off the video
output, the reciever is still powered up so it knows the time, etc.

True, but I wouldn't defend it on that basis. Electricity is a rather
expensive form of heating (and unwanted in summer, of course).

Standby modes don't really help you there. Unless they are of the Norman
Baker type, the set will be cooling down anyway. Switching my CRT TV on
from cold does involve a rather loud and scary invocation of the
degaussing circuitry, however, and possibly doing this too often might
have a detrimental effect.

Also seen in B&Q.

I've bought several of these devices for computer systems, but found they are
excellent for AV systems too. I have my audio amplifier powered through the
"master" socket (because it is the only device that must always be powered
whether I'm listening or viewing) and everything else that doesn't need to be
powered all the time to make unattended recordings is powered through the other
sockets. The switched equipment includes the TV set, which takes less than the
rated 2 Amps, and I've had no problems with this.

No it can't. Journalists, even some technical journalists, appear to be a
bit confused about the difference between *power* and *energy*, and of
course people who read them are not helped.

The question of instantaneous power versus
overall power consumption just gets thrown into the mix without any
comment or qualification.


What they're really trying to say is that the amount of *energy* consumed
is related to the *power* consumption (which could equally well be called
"energy rate") and the amount of time the equipment consumes energy at
that rate.

Depending on the ratios between working power and standby power, and
between on time and standby time, it is possible for the ratio between
working *energy* and standby *energy* to be anything you like, depending
on the details of the particular circumstances.

e.g. if you leave a typical device in standby for a year and switch it on
for one minute, it will probably consume considerably more energy in
standby than when working even if its standby power is less than its
working power.

Yes, that's right. Mind you, since the current changed very little
between on and standby, the power factor was probably about the same, so
the *ratio* between the powers was still valid.

We could. It would be perfectly valid, but the kilowatt-hour, or kWh, or

that appears on our electricity bills, so I would expect everybody to

I hadn't thought of that. What a good point.

Just about every DTT STB I have seen is without a power switch, so unless
people are going to switch them off at the wall, that's a lot of STBs all
sitting on standby - and an increasing number at that. Also, in most homes,
I'm sure you'll find the STB, TV, Video/PVR and DVD all plugged into a 4-way
adaptor and powered from one wall socket, and will therefore be left with
power all the time for the benefit of the recorder.

It seems to me that Sky+ users have the most energy efficient setup - one
box which needs stand-by mode and the rest can be powered off. Until DTT
PVRs with dual tuners become the norm rather than separate STBs all over the
place. I'm still waiting for one with a DVD recorder to appear at a
mass-market price.

The key to all this is reducing the silver box-count, in addition to turning
the telly off at night...

A kWh is 1000 joules isn't it, or is it 3600000 joules, I suspect it's
the second actually. 1 joule = 1 watt for a second. Thus 1kwh is

I disagree with that too on the basis that you cannot just replace kWh
with Joules -- you must do some scaling for the figure to still
represent the same physical quantity.

A better example of equivalent units would be the Pa and Nm^-2 -- 1000
Pascal = 1000 Nm^-2, just as 567.8 Pa = 567.8 Nm^-2. Indeed, the Pascal
is defined as one newton per square metre.

They're different units for the same thing, so both perfectly valid.
However, a Joule is a Watt-second, which is rather a small quantity of
energy when considering household electricity bills, so the kilowatt-hour
is the one in common use for this purpose. We *could* buy our petrol in
millilitres, but generally we don't because the numbers would be silly.

Of course. I'm amazed that shops in this country are *still* selling VHS,
DVD and PVR recorders without a DTT receiver built in. It's madness really,
because when the analogue signal gets switched off, there's going to be a
huge number of people for whom setting matching timers on the recorder and
on the STB will be too complicated.

The long-term answer to all this is to have a recorder with twin DTT tuners
built in. Then it will be the only thing which needs to be left on standby.
As long as that standby mode is well designed, power use should be minimal.

fair enough, but as you say, the STB and recorder would have to be powered
separately - unless the "inteligent" gizmo can detect the difference between
standby and full-on modes - then a timer recording on the recorder would
power-up the STB. This is all very nice fur us technically minded people,
but far too complicated for many to want to bother with. They are likely to
ask the question "how long can I leave all my stuff on standby for £30 ?"

My problem with this is that I think a lot of the criticism is
justified, but I get really annoyed by exaggerated claims which are
endlessly lapped up by lazy journalists. Take this quote, for example,
from Norman Baker, the Liberal Democrat's environment spokesman,
advocating a "polluter pays" approach to the standby problem:

"In the end, there has to be costs in the form of manufacturers paying
something to recognize the damage they are causing. Some of these
standby modes for televisions use two-thirds of the electricity that it
would if it were on. I think some people think that standby is a tiny
red dot that has no impact at all."

He'll be telling us next that a TV on standby uses *more* power than it
does when it's switched on. Actually that's a claim I've already seen
made, and of course for some values of 'on time' versus 'standby time',
it can actually be true! The question of instantaneous power versus
overall power consumption just gets thrown into the mix without any
comment or qualification.

Anyhow, my challenge to you all is to find a TV with a standby mode as
woefully inefficient as the one which so exercises Mr Baker's vast
political intellect. Name and shame, that's what I say!


Where can I buy a cheap mains socket adapter to measure the power ?

Of course. I'm amazed that shops in this country are *still* selling VHS,
DVD and PVR recorders without a DTT receiver built in. It's madness really,
because when the analogue signal gets switched off, there's going to be a
huge number of people for whom setting matching timers on the recorder and
on the STB will be too complicated.


And so the shops will sell them another box. Are you still amazed?

NB Everyone will blame the government and praise the manufacturers and shops
for coping with the demand. ;-(

No it can't. Journalists, even some technical journalists, appear to be a
bit confused about the difference between *power* and *energy*, and of
course people who read them are not helped.


If you look up "energy" in the dictionary, you'll find that the first
definition often refers to fuels like coal, gas, and oil. There's often
a difference between the common-usage of a term and its technical-usage,
but that doesn't necessarily mean that either are "wrong".

fair enough, but as you say, the STB and recorder would have to be powered
separately - unless the "inteligent" gizmo can detect the difference between
standby and full-on modes - then a timer recording on the recorder would
power-up the STB. This is all very nice fur us technically minded people,
but far too complicated for many to want to bother with.


Agreed, but these items would need to be left in standby anyway. The
"intelligent" mains splitter can remove from the equation such things as the TV
set, the auto SCART switch box, the hi-fi tuner, the CD player, the tape player
and probably your VHS machine too because you won't still be using that for
recordings will you?

By using a normal mains splitter as well as the "intelligent" one, you arrange
switched and unswitched mains supplies to your hi-fi/TV equipment and plug as
appropriate. In my case the "master" unit that controls the switched supply is
the audio amplifier because that is needed whether I'm listening or viewing. It
doesn't save everything, but because the auxiliary mains outlets are switched
by physical relay contacts (I can hear them), it minimises the number of things
that are connected to the mains when the system is switched off, which is
cheaper and safer.

It's wrong if it has a technical meaning and you use it wrongly about a piece
of technical equipment, because in that situation the technical meaning would
be the expected one.

That's if there really are two meanings of course. How many meanings can
there be for "energy" and "power"? The former is a measure of the *amount* of
work done, and the latter is a measure of the *rate* at which it is done, the
two units being related in the same way as distance and speed. To use these
terms with any other meanings would only confuse, which is why the correct
meanings are the correct ones.

Not amazed that the shops are taking advantage of the situation. Just amazed
that the government is stupid enough to let it happen.
