Sammendrag
In this project we have looked into different streaming technologies, transport methods and ways of securing the content. We have performed an analysis of the performance in different scenarios, and tested different ways of distributing the content. We have also looked into some of the newest player technologies, and found the reasons for using them, or to look for alternatives. We have found that the best way to deliver content is to use multiple streams and assembling them on the client. This will take more bandwidth, but with todays internet connections this will be acceptable. The solution that we have suggested will enable people to pay extra for quality, while it is also possible to do both watermarking and encryption on the output stream. We have also had a look into watermarking as a DRM protection, but as this will only prevent the spread of content, it will not protect the media stream from being saved by the end users. Our recommendation for Filmarkivet AS would be to keep their current DRM system, since they already have a large amount of content protected by Windows Media DRM. Converting this content would take too many resources compared to the gain. The best option would be to develop their site using Microsoft Silverlight since they can use their existing DRM. To add internationalization to their site we recommend that they use separate video, audio and closed caption streams, since this will ensure maximum exibility
