HDTV Meets DSL
Lab tests tinker with delivery method
(old news - 07:47PM Tuesday Oct 14 2003)
tags: hardware · bandwidth
Though far from mainstream application, companies are busy trying to squeeze HDTV signals through DSL pipes. While video via DSL may not be far off thanks to compression tricks, HDTV signals require significantly more bandwidth and therefore pose a bigger headache. According to Light Reading, Net to Net Technologies and Tandberg Television are working on the problem: "The demonstration, which took place last week at Tandberg’s facilities, used two ADSL lines with each providing 10.6 Mb/s of downstream bandwidth. One HDTV MPEG-2 stream, encoded at 15 Mb/s, and one standard definition MPEG-2 stream, encoded at 3 Mbps, were simultaneously transported over the bonded ADSL lines, which in aggregate provided slightly more than 21 Mb/s downstream."

Of course the majority of DSL or cable users don't have one line providing 21 Mbps worth of downstream bandwidth, much less a second. The marketing execs for the companies are optimistic (naturally), claiming that MPEG-4 and Windows Media 9 compression will progressively make delivering HDTV signals over DSL easier. HDTV signals, which normally require 12-15mbps of bandwidth, could only require 5-6mbps via MPEG-4. The researchers certainly have time to tinker, since HDTV television sales remain sluggish, and the equipment required to handle MPEG-4 over copper remains expensive.

Most cable companies don't give that kind of bandwidth to their customers (coughCoxcough, coughComcastcough, COUGHcharterCOUGH, coughAdelphiacough) and nor do DSL give as much either

Re: Yeah right...

My D-VHS D-Theater unit runs at up to 28Mb to deliver 1080i. Even crap DVD is 6-10Mb. And by the time telcos actually get off their ass and deploy even decent 1.5Mb service, HD will be old news in favor of something else.

Why would a Cable Co. Need to deliver HDTV over DOCSIS? They just do it in a 256 QAM carrier.

That bandwidth will be clogged with dozens of not 100's of regular HDTV feeds by 2006 if the FCC has their way and if I'm not mistaken HD feeds take about the same bandwidth as 6 regular NTSC feeds so no matter what happens, bandwidth will be a premium both for HSI streaming services as well as their regular DCATV/HDCATV services.

It's not as simple as that. You can have 2 HD and a SD or two in a 256QAM with Rate Shaping. If you look at 1 analog channel that takes up 6Mhz of spectrum and you replace it with 2 High Def's and 1 Standard Def in a 6Mhz wide QAM. your getting 3 channels for the price of 1. I fail to see your logic.

A 8VSB over the Air carrier has a HD and a SD

All the FCC is requiring is that OTA stations (CBS, ABC, FOX, NBC, WB, UPN etc.) must broadcast HDTV. Cable companies will still be able to send analog signals over cable and the same goes for satellite. The only reason the FCC is making broadcast stations switch is that they want the spectrum that they are currently using.

Re: Yeah right...

The FCC is only requiring that stations broadcast in digital. Not High Definition. There are several stations in the Chicagoland viewing area that broadcast nothing but standard material over the digital stations. Fox has the "enhanced definition", and one station that has 6 sub channels all with different programs going on (they must be loving it).

I said a few weeks ago that they would have to resort to sending video feed in mpeg-4 compression. zzt zzt divx is taking over. If they were able to get it down to where it was less then 5mbps they could fit it over existing cable (OOL for example) or adsl (verizon 7.1mbps for example) which could be feasible. now if only I could flick a switch turning that bandwidth normally for television signals into bandwidth my w4r3z downloadz0rz

This could happen, maybe over a type of line like ISDN. I don't see anyone being able to get that kind of bandwidth over a regular ADSL line. It would be nice though, but I think we need to work on DSL being more widely available first.

Re: Possible

are you on crack? obviously you don't know what the %&^% you are talking about. ISDN is short for Integrated Digital Service Network. It is max at 64 kiloBIT per second per channel. Sometimes two channels are 'bonded' to create 128 kilobit service with a 9.6kb 3 channel feature.

Now, how do you actually think that 128kb ISDN is faster than the average 1500kb ADSL service?

math 101:

128 kb is less than 1500 kb ADSL.

Sounds great but whose phone line can handle sync at 15Mbps+?

Plus I don't want over compressed signals so I can see demonstration of how to screw up an HD broadcast. That's the over the air affiliates jobs.

Yes, everybody, not just big companies would benefit from it, just try and get the big companies to get it. They're too stupid to see the future of anything other than their giant checks. They go insane for losing a few bucks, but fail to see that the return on the investment far outweighs the loss they take setting it up.

DSL may beat Cable in my book, but Fiber beats everything in everybody's book. Oh, and let people setup servers and charge by the byte at reasonable rates, low enough so you can beat any other competing technology at even the old grannies checking their E-Mail once a week to see what the grandkids are upto.

Why is it so hard for them to do this?

They used MPEG-2 for HDTV as a standard because it's less demanding software and more available on market. MPEG-4 will offer the same quality, but at the price of requirement of higher system requirements.

MPEG-4 is not a replacement for MPEG-2. Also, MPEG-4 will not offer the same quality at a lower bitrate. MPEG-4 was only designed for very-low bitrate applications (low bitrate meaning under 1.5 Mbps).

MPEG-4 is full spectrum codec that can actually scale higher than MPEG-2, it's quality bit for bit with MPEG-2 is better. Microsofts WMV 9 is actually a little better than most MPEG-4 codecs including the now famous
MS mpeg4 V3 otherwise known as divx 3.11, which was made by microsoft.

Full spectrum? Who told you MPEG-2 can't handle that?

I won't argue on quality, since MPEG-4 was not designed for high bitrates in the first place.

Re: It would't be HDTV...

When i said MPEG-4 is full spectrum it means the limit on the amount of delta "blocks" it is hardware dependent. MPEG-2 will not do that.

MPEG-2 can handle it at about 19-29 Mbit/s, which makes it useless.

MPEG-4 is a suitable replacement for mpeg2 and IT WAS NOT DESIGNED FOR LOW BITRATES ONLY (it depends on the codec, some are for high bitrates only). MPEG-4 is even more capable at high bit rates than mpeg-2. MPEG-2 compression is only slightly different than MPEG standard we all know but it will scale.

MPEG-4 can have not only higher color precision, but more blocks and flexible placement of key frames. Most of the new MPEG-4 ( H.2xx ) used for tv will need special hardware to decode because of the math involved.

If you don't believe that mpeg-4 looks better than MPEG-2 at high bitrates go and buy the new Terminator 2 special ed. with an HD version of the movie on a seperate disk.
It is encoded with wmv9 ( made to play on your computer --based on MPEG-4 H.211) and see if you still believe that.
Not only is it higher resolution but smaller in size (around 4 GB instead of 7).

The only thing holding MPEG-4 back are the prices involved in the hardware due to the faster processor speed involved. MPEG-2 was made to be played on hardware that would be cheap to the consumer. Assuming that MPEG-4 is only for low bitrates is a misconception.

Could you rephrase that, please?

Incorrect. MPEG-2 will handle 100+ Mbps.

Again, this is incorrect.

What?

Compared to MPEG-2? Both can have exact color precision (4:4:4).

This is true. But so does MPEG-2 and any other video compression.

I'm not going to spend all my time trying to teach how the math in all delta based compression works, because it would take forever, but you need to look up the what mpeg 4 is. Just do a search on google.

You seem to know very little about what MPEG compression
is. By saying MPEG-2 is better than mpeg4 or that mpeg4 is for low bit rates only is crazy. Mpeg4 compression works much the same as MPEG-2 only with higher order compression.
But i'm afraid its of no use you will continue your ingnorace obviously.

what started this whole topic was correct.
"They used MPEG-2 for HDTV as a standard because it's less demanding software and more available on market. MPEG-4 will offer the same quality, but at the price of requirement of higher system requirements."

this is basically what the article above pointed to, and i'm sorry you missed that.

Re: It would't be HDTV...

why shoud i teach you , when your the one who is wrong.
I don't know what website you have been getting your info
but find another, or better yet buy a book on visual compression.

"MY sources are the actual specs, going to MPEG standard meetings, and talking to the main designers"

sure, and you don't know what delta compression key frame is.

The actual specs in reality are a complicated mathmatical
algorithm, and i have been a mathmatics student for 4 years
and am only beginning to understand the "actual specs", or the compression used. It is very very very complicated. My post was not to insult you but MPEG-4 is not just for low bit rates. You still have yet to respond to the H.2xx codecs which are probably going to be standard for the next
generation HD-DVD format, since the BLUERAY disk is proving much more expensive than oringinally thought.The bit rate will probably in my guess be about 9-12 Mbit/s,in other words about twice the average bit rate for a dual layer format DVD at 720 by 480.

here is a quote from microsoft about WMV9, which in my is the best current real time mpeg-4 based codec.
please read
»www.microsoft.com/windows/window···ecs.aspx

Windows Media Audio and Video 9 Series provides compression improvements of 20% for audio and 15% - 50% (most dramatic improvements seen at higher bitrates)

did you notice that last line? here is the link, its in the upper middle and bottom. »www.microsoft.com/windows/window···ity.aspx

the reason for the WMV9 comparison is that it is the only playable version of H.2xx playable without specialized hardware.

what's more impressive it the H.262 codec, which puts MPEG-2 to shame. To bad it needs an expensive hardware decoder, only 2 frames per second on 3GHZ. That can be overcome easily with specialized hardware decoders, which should come down in price with mass production to be as cheap as a set top dvd player though. Intels newest SSE will have native support for it, so no worry's.

this is just one example H.2xx being another.
WMV9 is also for low bit rate, but a seperate encoding engine is used for anything below a certain threshold, don't know what it is though.

by the way WM8 is not based on the H.2xx standard like the 9 ed, so please don't compare until you have encoded with the new ed.

Re: It would't be HDTV...

So you don't really know, do you? Ever been to a meeting? Ever talked to anyone?

Then you would know that MPEG-4 was never designed for high bitrates. Only later was a high-bitrate profile bolted on to satisfy a couple of people.

MPEG-2 is and always will be the standard encoding and transport for HDTV resolutions.

You keep throwing in garbage about how MPEG-4 can do something and MPEG-2 cannot. Stop referencing Microsoft's marketing (which talks about their proprietary codec NOT MPEG-4) and POINT to it in the spec. Give the page number and paragraph, and then quote it here for all to see -- and I will be glad to concede.

Until then, quit wasting our time by giving made-up information.

Cable is far ahead

Very interesting, but I disagree that these developers have lots of time to tinker with this. HDTV sales may be sluggish now but just wait until next summer/fall when Sony is planning to mass produce the first widescreen HDTV with the tuner built in and the cable card slot on the tv. Oceanic Time Warner here in Hawaii is already preparing for this and says they plan to be ready to offer all us Oceanic cable users this technology as soon as those tvs are available. (We usually get technology like this before any other TW franchise). This will mean no more renting of the cable converter box. These tvs are to be offered at more reasonable prices than what we currently see for HDTV ready monitors. Sony says the first will be a 32" widescreen. I am eagerly awaiting this development as I don't want to rent a box when it is more cost effective to have the tuner built in and simply slide the card provided by the cable company into the slot on the tv. I think these tvs will greatly speed up the transition to digital and HDTV. The DSL tinkerers may get left in the dark if they tinker too long.

HDTV over dsl?

Ok, coming 2007 broadcasters have to be ready to deliver hdtv. So my guess is if you get cable tv via cable then HDTV will have to travel over cable, no? DSL and HDTV are the bells trying to get a foot into broadcasting? Don't tell me that after all this push to convert to HDTV they will not have a medium to deliver the signal.

AHHHH so many questions.

You are correct, sir. Provided 85% of the given market can handle it, the FCC won't allow for any more analog signals floating in the air from television stations effective January 1, 2007 (with the possibility they may extend this shut off date). They must all be digital (not necessarily HDTV, but with stations already investing in new equipment they will need, most take the plunge all the way.)

What I want to know is this...

Wow! Oh gee! 20 times faster and I could too!

"The demonstration, which took place last week at Tandberg’s facilities, used two ADSL lines with each providing 10.6 Mb/s of downstream bandwidth. One HDTV MPEG-2 stream, encoded at 15 Mb/s, and one standard definition MPEG-2 stream, encoded at 3 Mbps, were simultaneously transported over the bonded ADSL lines, which in aggregate provided slightly more than 21 Mb/s downstream."
So, all I have to do is get a DSL line that is 20 times faster then my current one, and then I'll get to MAYBE watch *one channel* of HDTV! Yay!

Give it up. HDTV over DSL? Don't make me laugh.

You are forgetting about satellite too, which is the best option IMO. Much more reasonably priced than cable. Yeah I know now everyone can get it, but even less people can get dsl. I just don't see a huge market for HDTV over DSL, not to mention the numerous technical hurdles. Copper lines just weren't made for TV.

The people who wrote and are quoted in the article are clueless.

Cable operators' biggest advantage over telcos in the residential market — the massive amount of bandwidth they can deliver — will quickly shrink over the next 18 months if DSL developments at Supercomm were any indication.
Combined with...

AFC, which decided to pass on developing products with the ADSL2 standard and go straight to ADSL2+, wants to provide enough capacity for carriers to have multiple choices in video, said Corey Geiger, vice president of product management, marketing and customer service. “I see the offering being one, HDTV, and two, other standard video streams,” he said.
= HILARIOUS!
3 streams! Compared to digital cable's 100+? Yeah, they'll be catching up. Sure.
quote:
Driving some of the interest is the emerging MPEG 4 encoding standard, which can squeeze an HDTV signal that normally needs 12 to 15 megabytes of capacity into a 6- to 7-megabyte space.
Anything about rolling out MPEG-4 for HDTV is marketing muckety-muck. HDTV would look terrible at that bitrate. Plus, it shows a complete lack of understanding what MPEG-4 is. One thing it is not: a replacement for MPEG-2.

HDTV Standards

A normal signal that is compressed with MPEG-2 is a ~19mbps stream from the broadcasters. By compressing this even more it is losing the effect of true HDTV. If anybody thinks that those bitrates are acceptable then they need to get their tv checked. I hope they don't make HDTV look bad by trying some compression tricks when they should realize that this could be easier with fiberoptics.

Pie in Sky?...Dish in the Sky

The best HDTV quality is broadcast OTA (over the air free)second would be satilite, although compressed still ok. Compressing it further would be questionable but if telcos and cable operators get there way they can dig into your pockets a little deeper. Imo

Re: Pie in Sky?...Dish in the Sky

Over the air is called 8VSB and it most TV broadcasters have a HDTV MPEG PN 1 and a Standard Def TV MPEG PN 2 typically contained in the same 8VSB carrier.

Ah, yes...

All HD broadcasts are compressed (MPEG-2), but you do have a larger bandwidth available from OTA.

My eyeball tests can't tell the difference between an OTA broadcast and a Dish net signal (which is reportedly ~14-15MB/s), but that's on a 55" set. Those with good projectors may be able to tell it apart.

Japan and Korea are far ahead of the rest of the world in bandwidth availability. Most ADSL providers are offering 26Mbps, and expecting 50Mbps service within a year. 100Mbps fiber is available, but expensive (US $38/month).

I'd much rather continue to see satellite, dedicated cable, or OTA as DTV distribution mechanisms though.

Re: .

oh man, 38$/month for 100MBPS, soooooo expensive!

Do you realize a 100MBPS line at cheapest (cogent) is $1000/month and you call 38$/month in japan expensive?

I've got 26Mbps DSL

I live in Japan, I can confirm that I have Yahoo! BB Japan's 26Mbps ADSL in the apartment where I'm staying. I get downloads of about 1-1.5MByte/sec at the most usually, but I'm going to be moving into a new apartment soon, and as soon as I settle I'll hook up with NTT's 100Mbps fiber optic service. It's 100/100, both ways. It's expensive (about 5600Yen or 50bux at the current rate), but I think it's worth it - I tried it, and my jaw dropped after I saw the download speeds (from inside-Japan web sites, and playing on Tokyo game servers with pings close to zero). The landlord of the apartment where I'm at right now is paying about 3000Yen or 25 bux a month for unlimited 26Mbps dsl. It's 1Mbps in upload (physical limit). Next month, eAccess here in Japan will launch 40Mbps ADSL (still 1Mbps upload). Despite all this, I still think that fiber optic cable will ultimately blow all the other temporary/old technologies - dsl/cable/satellite/etc. It will take time in bigger countries such as the U.S., since the cost of laying out all that fiber is extraordinary and the cost can't justify the ROI. We're lucky here in Japan because NTT saw the potential of fiber YEARS ago, so they basically blanket-covered the country with fiber optic cable. The city where I live is not big at all (pop 84,000), it's kind of rural actually, yet it is covered. Most areas where people live ARE covered by fiber.

IF!

If I were to enable Fastpath, on Dual-Pair ADSL I could have approximately 13.7Mbps Down and 2.3Mbps up. With 2 Phones lines Using a Access Concetration style switch to "Aggregate" a heap of bandwidth I could have 26.7 MBPS Down 4.6 MBPS up, and 3 Lines 41.1 MBPS Down 6.9 MBPS UP.

This speed would be possible if you had enough money, I knew somebody at SBC REAL WELL, or They simply make ALL speeds available to those who can get them, for a set price.

As it stands on the Inner-Pair (2 of 4 Wires to the Phone Jack) I have tested throughput in excess of 7mbps Down and 1mbps up consistently.

So what we should be asking, is when do you want to give some of it to us, NOT, Is it possible.

1 term: FTTH, scrw thoz who say otherwyz!!!

If it ain't fiber to the home... If it isn't fiber owned by the PEOPLE, not the stinking cablecos or telcos. If it ain't fiber maintained by a non service provider, then I am against it.

IMPORTANT NOTE: Both Hillary Clinton's and Chuck Shumer's offices people were VERY RUDE to me when I asked about a chance to discuss the issue with someone, ANYONE at their office. SEEMS the TELCOS and CABLECOS freaking OWN both of my senators.

I can assure you that I will be campaigning against both of them with lots of energy. Don't trust either of these creepy senators, could it be that they are both scum(?), MHO, at least in as much as how their people treat callers.

Fight the good fight, talk your county government into taking on FTTH, that is the answer!

Well, I'm interested

I have 20Mb VDSL right now with three video streams, so I'm interested. However, I consider it unlikely that Qwest will spend the money on an upgrade to provide HDTV. They aren't expanding their existing system, due to the cost of deploying remote terminals.

The three streams, BTW, means those that are delivered to the house. It doesn't mean you only have three channels to pick from. The streams are switched at the head end, so I've got the normal 100+ channels to pick from.

Re: Well, I'm interested

Does QWEST (Next Level network) even offer a HD set-top box? Your three streams are at what bit rate per stream?

Re: Well, I'm interested

As far as I know, there are no xDSL set top boxes in production -- just the test this topic is about.

The current VDSL system Qwest is using has three streams at 5Mb/stream.
