Sometimes the broadcaster scales it once, and then your TV scales it again if it isn't a perfect match, and artifacts show up all over the place.
The other reason it's better to upscale locally is because the low definition signal probably has less compression applied to it, so you're not going to get as much loss. Depending on your provider, of course. Here in the US, the largest cable MSO (Comcast, aka Comcrap) puts *three* high definition channels on a 6 MHz slot, resulting in lots of visible compression artifacts and skipped frames. Analog never had these problems :)
well, I guess if you give them enough bandwith, it would work.
You also can see the same on other astra satelite channels where the broadcaster tries to save money by using less bandwith; regardless whether its HD or not.
I guess when it comes to the quality of the scaler, the average tv will loose in quality to those professional ones.
This might be an odd place for this, but...
I've been fooling around with Amazon Cloud lately.
They have a machine you can install up there that runs an instance of Wowza.
So if you put a bunch of media files up there, and do the magic things required to make Wowza work perfectly for you, you can create your own television channel for home viewing, with your own programming.
And it'll stream to your phone. Or tablet. Or desktop.
Which is rather spiffy.
Not sure about costs yet. I suspect, relative to setting up a television station, it's very inexpensive. I know setting up the Cloud machine is remarkably inexpensive, and fantastically flexible (to allow you to hone in on exactly the pricepoint you want, to get charged only for what you use).
Honestly, this stuff is rather freaky.
Subject: In reply to my own HD rant...
On the analog TV I had everything connected via SVHS/Hosiden, looped through the A/V amp, since the woman's acceptance factor of having only one simple remote control for everything is quite huge.
When I wrote my original rant I had just exchanged the TV set and I didn't touch the wiring out of poor lazyness and only wondered why the DVB-S signal was monochrome and I had to switch back to Composite. Then I read the manual and found out the manufacturarer was too cheap to put in SVHS decoders, so I was back to composite completey. Which my A/V amp looped fine through the Hosiden connectors, somehow. Anyway, composite is even awful on analog SD displays.
Then I got a new DVB-S receiver, this time with HDMI support and now I see the light. Although the TV is only capable of 1080i and I am running on 720p now, the image is perfectly clear on the HD stations and even the SD signals look far better now, although the variety in the signal's color hues, etc is still more visible than on analog.
I also connected the DVD player via some ultra highquality SCART cable directly into the TV and found out that both the TV and the player are able to communicate in YUV/Component via SCART (the original scart specs only supported RGB afaik), so I am able to get at least a progressive SD signal through to the screen. Which vastly improves DVD signal and Baraka as well as my Cashern DVD look brilliant again. They are my reference material, since they have the highest bitrate. Cheap DVDs still look crap but at least the major labels do some good work and animated childrens movies are acceptable to watch.
The Wii is ok too, only downside is that I do not find a cable with long enough and separate audio connectors to get the sound into the amp again... (Also, cheap YUV cable suck donkey balls, since they lose signal too often!)
So, all in all, HD TV screens with proper analog inputs is quite likeable, but the downside is that I'd need to upgrade the A/V amp in order to get an acceptable WAF again... We now need two remote controls and select the inputs on the TV instead of using one single input and change the source via the amp's RC. (But this makes it possible to tune contrast/brightness/colour on every single input)
Now, the thing that really unnerves me is that I need to find a fast enough USB flash drive in order to properly record/timeshift HD signals on the DVB-S device. Is there a flash drive that is able to write at about 10MB/s? The receiver claims that he needs this speed...
When I made the switch from DirecTV to AT&T U-Verse, though, I suddenly had a reason to use HDMI. I've had a PS3 longer than that, but never really used it enough to demand HDMI connections.
Now, I still have all the audio going to the A/V receiver, and all the video feeds, with the exception of an old VCR, go directly to the TV. Since there are now three components involved--source, A/V receiver, and TV--I got a Logitech Harmony universal programmable remote.
It's not cheap, but it works great. It's very easy to program, and it even has an on-board "Help" button if something goes wrong. It will go step-by-step, asking simple yes or no questions about whether components are on and set to the right inputs. Very easy to use.
I have thought about that. But we now live in a world of 7" tablets for under 99€, can't somebody fix an IR port to them and make a real stylish remote control app? The 79€ variant of the Logitech Harmony can only control 5 devices... My Pioneer D812 has a remote with support for 8 devices, but has some memory issues and would need 3-4 programmable buttons more. I am still not willing to spent 150€ for an almost ordinary remote.
well, I have used the b/w display version of the harmony.
since the remote tries to be clever, it depends on the devices how good everything works out.
if you only have absolute controll commands (power on; power off; input n} everything works fine.
but if you have one device which has i.e. toggle power on/off or toggle lists like next input; next input,..., you're completely lost.
The harmony tries to mirror the state machine inside of the device; if a command is lost, you have everything out of sync, and you have to fix the state machine on the harmony.I
I liked my st00pit programmeable remote that came with my onkyo; but it died by some beer shed over it :-( harmony? no thanks.
btw, I've seen that there _is_ an android remote with samsung hardware offering just a remote with touchscreen...

Such apps exist, but they work by sending remote control signals into "Teh Cloud™" which then relays them back downstream to your set top box. And it only costs $9.99 per month to be able to do that!
Of course, it's our own fault for being st00pid. We should just put our racks of A/V equipment on the side of the room where we're actually sitting, leaving nothing on the other side except screens and speakers. Then we wouldn't need remote controls.
Fri Feb 15 2013 08:31:51 PM EST from generica @ UncensoredNetflix finally offers me enough value that I'd consider paying for it.
I'm thinking of canning my subscription. The limited range of selection is starting to bug me a little.
Well when they lost their contract with, Stars was it? They lost a pretty good bit of content.
Thu Apr 18 2013 20:32:25 EDT from IGnatius T Foobar @ UncensoredSo what's the most versatile internet-to-tv hookup these days? Roku? Apple handcuff TV? Google TV? Roll your own on a Pi?
XBMC is clearly the answer.
the newer pi with 512MB ram is probably a cheap and well explored option.
however, just booting a pi-bootimage on the cubieboard did not work. (which has 1g Ram but uses the same SOC - A10 all winner)
I didn't bother to look at the boot of the PI image (which works on one of the older PIs with 256 MBRam) via the serial console.
One main difference between pi and cubie board which might be pro-pi is that the pi also has a FBas chinch plug for elderly TV, the cubieboard just a HDMI port.
If you care, I could have a look at whats going wrong with the xbmc boot image on the cubie board.
I happen to have one of those "elderly" TV's ... a 32" CRT, standard definition.
I also have a 40" LCD with a 720p screen and an older computer built into it, and no, it doesn't seem to work with an external source. I wonder if XBMC can be made to boot on that.
I have a Roku. It's hackable, as I understand, although honestly, I don't watch enough television to make it worthwhile.
