Undisclosed Markets to Participate in IPTV Trial 141

prostoalex writes "Associated Press has the story that three communications corporations are doing test trials of IP-based television in undisclosed markets. From the article: "SBC Communications, the dominant local phone company from the Midwest to California, is deploying a full-blown IPTV system that it plans to launch by year-end in at least a few undisclosed markets. Verizon Communications plans to offer some interactive IP-based features on top of a conventional digital cable service... BellSouth has expressed doubt about whether a cable rollout makes financial sense, the company sees enough potential to trial IPTV technology in undisclosed markets." Currently about 1 mln Europeans get their television via phone line."

    The three Bells are using technology from Microsoft Corp. (MSFT), a coup for the software maker after a decade of frustrated attempts to extend its software's dominance from the personal computer to cable television.

    Many bemoan that dominance in the PC world, but the choice of Microsoft might mean greater ease in the effort to meld TV with the Internet.

    "If you're going to be implementing some new capability that requires software, they're the go-to company," regardless of whether they have the best technology, said Leigh. "Who's going to fire you if you choose Microsoft? If you choose Digital Data Wack, and it doesn't work, then you're going to get fired."

    It's sorely disappointing to continue to see this attitude. Many of us "bemoan" Microsoft because their software doesn't work, exactly what this analyst claims they're trying to avoid. Do you get fired if you choose Microsoft and it doesn't work? What's wrong with this picture?

      Do you get fired if you choose Microsoft and it doesn't work?

      No. Because it's Microsoft. If you choose Microsoft and it doesn't work, you get to pass on the blame; but nobody in the corporate world blames Microsoft, since Microsoft is seen as unavoidable, almost a force of nature. If you choose Microsoft and it doesn't work, then nobody does anything about this your customers just have to put up with using a product that doesn't work.

      In other words: No, because if you choose Microsoft and it doesn't work, you get to move the goalposts of what constitutes "working" to whatever crappy point you're at. It's like that old joke, how many Microsoft engineers does it take to change a light bulb? They don't change it, they just define darkness as the new standard.
    • Apple has a patent out on an implementation of TV in quicktime. you can read about it here. []

      Microsoft proably has the cash to muscle out (or buy out) a lot of start ups in this area, but It wouldn't suprise me to see someone like apple, or maybe someone less consumer oriented like cisco stand up to microsoft and not let them take the market without a fight.

    • Personally, I'd be tempted to fire someone whop chose MS even if it did work, if that was their only reason for choosing them.
    • What's wrong is that you choose Microsoft and it works just enough not to get you fired :)

      It works most of the time and in much of the way it should always leading you to hope that with a little more tweaking it would be perfect.

      As afraid as the telcos may be, I think that they still have a strong foothold both in the wireless phone world and the fact that there is never enough bandwidth.

      With a phone line and broadcast/cable tv, there is never a bandwidth problem. The TV station can send their signals over the air and from that point anyone can recieve as much of their programming as they want. As we start routing everything over IP, we had better hope that new technologies emerge to provide guaranteed connection availability and bandwidth because nobody wants their Desperate Housewives to be laggy.

    Wake me onces TV companies begin to distribute shows (either paid or free w/ commercials) over something like BitTorrent. If they release an "offical" video file onto the web and then attack anyone who distributes a version without commercials, then there won't be that big of a problem with P2P sites since everyone who watches the show will also see the commercials. The only people who would object would be cable TV providers since they no longer have a purpose. This would also get around any FCC problems.

    To make sure people watch the commercials, you can use a custom player/P2P app that disable fast forwarding during commercials the first time it is downloaded or some other method to make sure they watch X seconds commercials for every Y minutes of the show.
    Free iPod? Try a free Mac Mini []
    Or a free Nintendo DS []
    Wired article as proof []
    • And a week after that custom player/P2P app is released, there will be hacks and alternatives.
    • I agree-- a p2p system to distribute tv is the way to go. And it can happen to much of America if low cost municipal WIFI takes off. That in and off itself would be sufficient to get enough data across, and the added competition would precipitate a sharp drop in broadband prices.

      As for supporting production, how about embedded ads in the video? product placement?
    • Mod him up! Except for the silly thing about custom players. Give me standard MPEG-4. You have no more certainty people will skip the commercials than you had with people muting, or leaving the room for water/pee during the standard broadcast.

      And, the distribution costs are so negligible with a bit torrent type system! Think about what it costs to run a full broadcast system, versus hosting a torrent.

      But how much exatcly does it take to send a proper HDTV signal?

      Anywhere from 4 to 37mbps. 4 mbps would assume the low end of a DTV (that's SD signal), encoded using the normal MPEG-2 DTV standard. 37mbps is the highest HD feed I know of; it's the bitrate found on the D-Theater D-VHS source tapes. More realistically, a proper HD (720p or 1080i) signal over the airwaves is between 20 and 27 mbps. So we are talking about a decent amount of bandwidth here.

      Of course, it's more likely that they're encoding in an MPEG-4 or Windows Media 9 format, given that the use of a set-top box eliminates the need for maintaining the HD standard of MPEG-2 video plus Dolby Digital audio.
      • Multicast cuts down on this consideribly (not the real bandwdith...but with many customers). Hopefully this will increase the use of Multicast (I'm not holding my breath). It would be nice to see wide deployment of multicast across the Internet (Internet2 is already fully multicast enabled)
      • Typical HD contents here (satellite) is 13mbps (720p 95% of the time, mpeg2 of course). Looks great :) Record it and convert to mpeg4 yourself, makes nice DRM-free HD DVDs (on DVDRs). No need to wait for whatever new expensive format/disc comes out in a year or 3 :) Pretty CPU intensive mind you. OTA seems to have nice high bitrates, wish I could receive some feeds.
      • "Anywhere from 4 to 37mbps."

        What does that work out to in cycles per second (Hertz)?

        • That depends on how the data is encoded. ATSC (USA OTA HDTV) fits 19 Mbps in a 6 MHz television channel. Digital cable can support 39 Mbps in a 6 MHz television channel.
    • For an off-air digital broadcast we get 19.3 Meg of bandwidth. When we air a true HD program we give it a minimum of 14 Meg. A native HDSDI stream is 1.5 gig. Even when it gets mux'ed into a ASI stream its 270 meg.
    • Let me answer it this way: Alcatel designed it's next generation DSL systems (likely the VDSL systems SBC will actually deploy) to handle about 20Mb/home (48 homes equally share 1Gb/s). They figure this allows something on the order of 1 HD, 2 Non-HD, 2 telephone call, and data all traveling on the line without interference (I may be off a tiny bit there, but it's close to what a VP at Alcatel was talking about at Next Generation Networks in September).

    I work for a small publicly-owned ISP serving an island in Southeast Alaska [] and we're currently selecting vendors for our own IPTV offering. Many, many small telcos all over the country are in the same initial stages of IPTV projects -- either evaluating or getting ready to make the leap.

    Most of the hardware we've been looking at uses MPEG2 encoding but in the near future the standard is likely to be either MPEG4 or some form of WMV. Microsoft has been aggressively pushing its video codecs and they seem to be gaining traction in the marketplace. However, they're not gaining as much acceptance as they otherwise might in the video world because at this point their reputation precedes them.

    To a small player like us their previous behavior in other markets is more than a little alarming. A Comcast- or SBC-sized provider presumably might have some amount of leverage with Microsoft but what kind of consideration can you expect when you're a tiny little speck on the map in a place few people even know exists? Choosing a proprietary Microsoft standard over a reasonably open industry standard could leave you at Microsoft's mercy and, well, they're not known for mercy, are they?

    From the two articles, i don't get everything.

    First, why do you need IP for TV ? over ADSL, it's a lot better to send it in raw ATM. Of course, you can use IP to broadcast TV to the DSLAMs. And if it's IPTV to play TV on the computer, what exactly is the use ? Isn't it better to get it directly on TV ?

    Then, why do you need Microsoft for that ? Are these Bells not using MPEG2 or MPEG4 for TV ?

    And, 1mln users in Europe for TV over ADSL ? It's very very low ! There are about 700 000-800 000 only in France: France #2 ISP provides TV over ADSL [] as part of their triple play solution, and they have reached 600 000 [] people subscribed to the triple play offer.
    Also, their triple play offer, and especially the freebox, is running Linux, like most of their whole architecture, so how exactly the Bells' choice is a coup for Microsoft: thet are entering a market very late. In France, all of it has already been taken, with the 3 major ISPs already offering TV over ADSL. And I can't see how Italy could top that, with their currently expensive ADSL.
    Moreover, they're already working [] on providing HDTV through their triple play offering.

    So i think either i missed the point, or both articles are (at least partially) wrong: some other people explain here that several ISPs are also offering triple play offers in the US or Canada. Can someone explain me ?

      > First, why do you need IP for TV ? over ADSL, it's a lot better to send it in raw ATM

      What everyone expects from TV over DSL is interactivity. People want video-on-demand, they want to pause or record live, they want to provision their account, etc. At the same time, broadcasters and telcos are looking for new revenue streams. Without IPTV, the features mentioned above would only work if you add a hard-drive to each set-top box (STB). However, for deployments to hundreds of thousands of subscribers
      • Well, i'm quite skeptical about what you say. On's STB, the Freebox, you already get a lot of channels, there's already some interactivity (you can check your VoIP's answering machine from the OSD menus on the TV), and they're working on VoD (there's an external IDE port on the freebox). And i'm not sure at all the freebox system works with IPTV. My understanding was that most of the work was done on the DSLAM, and that resulting MPEG2 video packets were sent directly to the STB using raw ATM.


        • Interesting.
          If it is true that everything is in raw ATM at, I suppose that they wrote some kind of a communication layer for making requests to the DSLAM. If you know of a place where to find further information, I'm interested.
          • Yes, from what i've read, you are right. However, nobody knows exactly how it works. All this is just based on wild observing how all this work (and especially that what counts to get TV is your ATM download rate, not your IP download rate - since download rates on ADSL depends on the distance to the DSLAM, this is quite important to know, because the IP download rate is a lot lower than ATM).
            Someone wrote a paper [] (in french) about that. Basically, he guesses that channel hopping is done through IGMP reques
  • IPTV here in the UK. (Score:4, Interesting)

    One of the nearby cities, Kingston upon Hull (or just Hull as it's generally known) has had IPTV [] for some years. The hardware uses an ARM processor and the set top box version of RISC OS [].

    Interesting you can thank the privatisation of the telephone system for this development. The telephone system here in the UK used to be run and managed by the Post Office. Then when it was sold off the whole lot was bought by British Telecom (now BT) except for the network around Hull which was bought by the local Council (local government). Eventually the was privatised and became Kingston Communications who were for a while, the only phone company that wasn't BT. So the government restrictions on BT supplying television didn't apply and Kingston set up their own digital television service.

  • How many times must we say it. The internet is not digital TV ! Oh... wait a minute...

    But seriously I think the ability to get TV over the internet could be excellent all round. The consumer hordes can then use the internet TV services and the rest of us can use the "good old" internet.

    Hopefully all the idiots who make flash only, or plugin riddled, "crudsites" will all then fuck off to build internet TV related sites and leave the rest of us the hell alone.

    Hmmm... I can dream can't I ?
