  1. Re:Client Side not that bad on Inside the Cult of TiVo · · Score: 2

    Moore's Law
    Interesting that you bring up Moore's law since it applies to transistor density not network bandwidth. Note that internet bandwidth has NOT increased at the same rate as processor speeds. Client side hardware will get cheaper far faster than network bandwidth. This seems to favor client side PVRs.


    Whilst strictly speaking my point is a corollary of Moore's law, bandwidth does exhibit the predicted exponential growth. It is that exponential growth pattern that is important rather than the specific timeframe (indeed the time frame with regard to Moore's Law has varied between ~12 to ~24 months.). It also applies directly to the communication hardware (modems, DSLAMs, switches & etc) and servers. Furthermore since the hardware for a client side solution is adequate, increased performance on the client side is 'wasted', the result is the hardware cost is driven down and the human element of maintenance become an increasingly significant. Whilst on the server side the extra performance can be exploited incrementally and lower cost base increasingly favours the server-side solution.

    Internet Access
    While I am not disputing your particular business model, most people (in the US, much less the world) do not have access to high speed internet access (much less to a MAN). As such they will not be able to download good quality video files on demand, whereas at least half of the US is already recieving cable.


    We (well our parent Telco) installed the backbone specifically for a meta-project, a Digital City Initiative (http://news.bbc.co.uk/hi/english/sci/tech/newsid_ 960000/960909.stm) of which this project is a part. Though I believe that services like PVR enhanced DTV and VOD are the Killer Applications that will finance the wide-scale deployment of broadband network provision to ordinary consumers.

    3) Infrastructure (again)
    I am very impressed that you can serve 8000 users with 40 servers. I doubt however this will scale linearly. How will you do with 800,000 (something like Tivos current subscriber base). What about 8,000,000? As the complexity of the system grows, so does it's cost and its chance for failure.


    The nCube (www.nCube.com) video servers we use do scale in a linear manner. The platform is designed such that it offers a 'turn-key solution' that could be rolled out nationally in the UK on a city by city basis. It seems likely we will be licensing our technology in an International arena shortly.

  2. Re:Client Side not that bad on Inside the Cult of TiVo · · Score: 2

    Bandwidth, yes; and costly, yes; However that bandwidth and video servers are required for Video on Demand services and PVR is an additional service (and revenue) on the same infrastructure. Also both Moores law on hardware cost reduction and Metcalfs law on Network Utility are both at work, time is on side of PVR and server-side solutions are cheaper overall because it requires less redundancy.

    It is easier and therefore cheaper to maintain and enchance capacity on the server-side than on the client site, and it is not just the hardware cost, the engineers visit, travelling costs, no shows, it all adds up to increased cost base for client side PVR.

    I'm not sure about what you mean with your comments on Internet access, we don't stream the content over the internet, we use a IP enabled private MAN, so our solution does not require Internet Access. However we offer a 256Kbps Internet Connection for £10 UK pounds (15USD/EURO)pcm, and it is the most profitable part of our service at about 80% gross profit.

    The HD in PVR is used a lot more intensivly than one in a PC; continuously for the duration of use, the failure rate of HDs in PVR will be much higher than with PC's simply because they are used so much more intensely, coupled with the cost benefit of server-side mainternance, the economics clearly favour Server Side PVR.

    We use a cluster of 40 nCube Video servers with RAID totaling ~640 disks. The prospect of all failing at once is quite literally astronomical. They serve a current customer base of 8000, so we need 10th of the disks that a client side PVR solution requires. We also have more coverage because we only need to store 1 copy of any content and as the customer base grows this advantage over client side PVR grows.

  3. xDSL not CATV on Inside the Cult of TiVo · · Score: 2

    The server side model is dependant on massive bandwidth, which doesn't exist.

    'Massive' no, DTV can be delivered in about 4.5Mbps using current MPEG technology, which is hardly massive, and can be delivered over xDSL to about 3.5KM.

    'which doesn't exist' perhaps not widely, but we are starting to do this http://www.kitv.co.uk

    You'd lose the ability for all your users to access the PVR features simultaneously.

    This is only true assuming a cable infrastructure because of it limiting ring topology. xDSL uses a star network topology, and this restriction does not apply.

    And what about pausing/rewinding live TV?

    What about it ? Whilst we currently do not provide it *yet* because of development resources it is *absolutely* possible.

    There is no way that any existing, or forthcoming, CATV infrastructure can scale to support this to enough users to make it profitable.

    Wrong. We are starting to do this now, it is more scalable and cheaper (unit price) than the alternatives (Client side PVR) for the reasons stated in my original post.

    There are many other flaws in your argument, but it doesn't even get off the ground to begin with, so I won't go into more depth...

    Perhaps you should post them, and I'll shoot those down as well:)

  4. Client side fundamentally flawed on Inside the Cult of TiVo · · Score: 2, Interesting


    Doing PVR on the client side is a fundamentally flawed model. The server side model makes a lot more sense.

    1) The economics of storing one copy of a programme on millions of client side devices compare very unfavourable to storing the content on even massively redundant servers.
    2) Hard disks have a high MTBF when compared to existing media, VHS, DVD. Consumers will not accept the total loss of content with a HD failure. The economics of on-site mainternance require the simplest client possible.
    3) A server side solution can 'record' essentially an all channels, the resource requirements are order N. A client side solution requires exponential amounts of hardware to allow all clients to record all channels, order N^N hardware.
    4) The efficience of a server side solution means that more content can be recorded, even unselected historical choices.

  6. Interbreeding on Hominids: The Neanderthal Parallax · · Score: 2


    Interbreeding of closely related individuals also has benefits of bringing out other traits, which actually increases genetic diversity.

    Confirmed.

    Indeed interbreeding is very common in thoroughbred Horses, Pigs, Cattle and pretty common in Pedigree Cats and Dogs. That is why today we the most productive farm animals and most attractive pets in history. Typically interbreeding in not so bad when a very strong selection mechanism against defects is at work. In both these cases a only repeat winners (Races/Shows) are bred and very widely. Though this *can* result in a homogeneous group, it is not certain. Indeed it aid the development of new species, there is considerable genetic difference between the various type of horse, so much so that some types of horse can considered seperate species because they cannot interbreed successfully.

    The main issue is the accumulation of recessive genes and since breeders think in terms of breeding lines (not individuals), a strong selective mechanism is at work against recessive genes when they are defective.

    Interestingly in Humans almost the opposite mechanism is at work, modern medical science, indeed all social security diminish selective breeding and even legal prevents it. The obvious consequence is that Human species is moving from a qualitative nurturing strategy towards an quantitative nurturing strategy.

    The big problem for most Digital providers is they spent a fortune on infrastructure, a fortune giving away STB's that are obsolete after a year and a fortune on rights to Sporting Events. However not enough people are prepared to pay enough to watch sporting events events they used to get for free to balance the books. Sky are also losing money fast, they plan to be the last man standing, then winding up the prices and presure. However this is doomed to failure.

    To make Digital TV work, the providers need to provide new value added services that people are prepared to pay for. Games/Video/Music on Demand, High Speed Internet, and a truly Interactive (2Way) experience. The technology used by the existing Digital Providers can not provide these valued added services.

    1) Terrestrial Digital (ITV Digital) is broadcast only; no return-path/uplink; no On-Demand Services; No Email, Web or other Internet service. Client Side PVR only.

    2) Satellite (Sky) is broadcast only, si no return-path/uplink, so no On-Demand Services, No Email, Web or other Internet service. PVR on Client Side.

    3) Cable looks good on the surface but it has a big road-block. Its network topology is a ring, the capacity is finite and this causes big contention problems, it also has the most expensive infrastructure to install.

    4) xDSL, the new distruptive technology, it cheaper infrastructure than cable, includes a proper return path and supports IP; So true On-Demand and High-Speed Internet, the value added service to win.
