Dutch providers and tv-zenders start this autumn with a new cooperation for the distribution of video by means of Internet. That is necessary because of the fast increase of online video.
In the cooperation bond around the Internet button point Ams-IX<http://babelfish.altavista.com/babelfish/trurl_pagecontent?lp=nl_en&trurl=http%3a%2f%2fwww.ams-ix.net%2f>work some providers and the public broadcasting and RTL for common appointments and an open protocol with which video distribution must become by means of Internet cheaper and more reliable. The first technical tests starts this autumn. In the system most popular content on the servers of provider themselves it is put automatically. The previous years were there already mutual appointments between providers exchange band width at Ams-IX, the ' peering '. The new system goes according to the people concerned a step further. It ensures that automatically on servers of the providers to come stand whereupon they most examined video files the those pictures within its own network are able spread. That saves date movement to the providers and the servers of tv-zenders also less is by it charged. A similar system twists already internal at the public broadcasting. Ams-IX the video working party is open for all Ams-IX members. A subgroup with among others the public broadcasting, RTL, XS4all and Solcon develop the protocol and the appointments. We look at if we can an open system in which contentbedrijven offer directly to providers make and that can distribute then within their own network this way efficient possible further. And that this way automated possible, technical director of XS4All says Simon Hania. Oftewel: automatic caching of most interesting content at the ISP. We want agree an open protocol with which can be exchanged content and as closely as possible to the end-user can be brought. Then is finished automatically content. The most popular videos are added up by provider. If maximumaantal are reached, then the file is moved to its own network of the provider", lay Egon moult, consultant new media of the public broadcasting, from. *' worldwide unique ' * The system is formulated as internetdraft. Within a couple months must be it ready. The complete procedure, the totaalpakket, is worldwide still nowhere present. thus Simon Hania. The situation in the Netherlands is favourable for the cooperation between providers and senders because of Ams-IX, success of on demand-video at the public broadcasting and RTL, and the high number of broadband connections. In the Netherlands we everything have concentrated spots on a couple. Moreover we have here already much online videocontent and the question after that is large", Jan Paul Dekker, say chef of technique at RTL. Because it concerns a test it is not yet looked at there to possible business models and setoffs, although the protocol for that, however, space gives, or to legal complications. According to Hania there ' expressly ' it is not spoken concerning ' commercial models '. It is beautiful that that does not need also. We have rapidly come free behind what the common interests to be: content must come well and cheap at the end-users. *capacity problems* The company Jetstream provides expertise to several providers and technique for the test, says director Stef of of the soul. "at a couple providers already spullen stand which can be used immediately, and at Surfnet also a test will be set up", thus of of the soul, which set up the first live videostream in the Netherlands in 1994, of metalconcert in a gronings youth centre. Sometimes providers reach now already their capacity by the large number of internetkijkers. That happened for example in July then the NOS by means of the company Garnier live-beelden of the tour the France by means of Internet transmitted. Several providers walked towards then against their limits<http://babelfish.altavista.com/babelfish/trurl_pagecontent?lp=nl_en&trurl=http%3a%2f%2fwww.bright.nl%2fproviders-in-problemen-met-tour-de-france-stream>. Of the causes was that those stream were sent from one point, where providers did not cooperate mutually. All providers are not according to of of the soul always even glad with the old peering model: Because the proportions between the movement which does not flow back and forth equal be. The proportion is sometimes gone. According to the people concerned turn out better than expected the problems cause by the growing popularity of online video now still, but it are the question if that is concerning a couple year still this way. Now it is problem still no. But if the large catalogue with old programmes is ask easily by means of the remote control on the TV, then the question increases still much, and is possible it a larger problem becomes. thus Jan Paul Dekker van RTL. *Peer-to-peer not ideal * Recently British providers reacted incensed to the new on demand-videosoftware of the BBC, the iPlayer<http://babelfish.altavista.com/babelfish/trurl_pagecontent?lp=nl_en&trurl=http%3a%2f%2fwww.bbc.co.uk%2fiplayerbeta%2f>, with which at can look at tv-programma's. Software uses partly of peer-to-peernetwerk. That is advantageous for the BBC which less hosting - and has date costs, but unfavourably for the providers which complained that they were put to expenses by the British broadcasting. According to moult the BBC has made no good choice by choosing for p2p. "the BBC has not made wrong in advance good agrees with the providers make." Announced pilot of the Dutch public broadcasting with two Dutch universities to spread programmes of retransmission missed by means of p2p-software the Tribler still of start has not gone. To moult: "we sit still with right questions, therefore about that is at present still communicate nothing." Streamingexpert of of the soul do not find peer-to-peer uberhaupt arranged. At TV look at by means of peer-to-peer need you much more date movement. To have a stable retransmission there always extra capacity must be in case of the kijkers a its connection breaks." According to Jan Paul Dekker peer-to-peer on paper a beautiful idea seems: But for the providers duration is and uncontrolled. And we cannot as RTL enforce such as the BBC that people will install separate programmaatje. That a too high threshold is according to us."
