Voddler
Résumé
Voddler was a Stockholm, Sweden-based provider of a video-on-demand (VOD) platform and a streaming technology for over-the-top (OTT) streaming on the public Internet. In Scandinavia, Voddler was primarily known for the commercial VOD-service Voddler, which was launched in 2009. As a company, Voddler was founded in 2005 and developed its own streaming solution, called Vnet. Vnet is based on peer-to-peer (p2p), where all users contribute by streaming movies to each other, but, unlike traditional p2p, Vnet has a central administrator who decides which users that have access to which movies. Due to this exception, Vnet has been referred to as a "hybrid p2p distribution system", "walled garden p2p" or "controlled p2p". In addition to running the consumer service Voddler, the company Voddler also offers, since 2013, Vnet as a stand-alone technology for other streaming platforms. The service Bollyvod, a global VOD-service for Bollywood-content that Voddler built for the Indian movie industry, was released as a pilot in 2014.
Voddler Group went bankrupt in January 2018.
Voddler's streaming technology, called Vnet by the company, is a peer-to-peer-based video content delivery solution. With p2p-streaming, movies are not streamed from a central server or content delivery network (CDN), but from other users who have parts of the movie on their units after seeing the movie earlier. This process begins when a user clicks play for a movie and continues throughout the viewing time, allowing for seamless viewing. After the viewer has completed watching the video, parts of the video file remains for a time on the user's device. Popular content, that is watched by many other users, remain longer on any one user's device than less popular content, which more quickly is removed from the network nodes.
Compared to server-based streaming, p2p-based streaming saves on data costs for the service provider, at the same time as the distribution becomes more robust, since it only grows stronger with every additional user.
