Due to the fact that popular movies are accessed frequently compared to less popular ones, the RAM can be supplied only to the popular movies who have higher number of users accessing them.
DIVX STREAM MOVIES MOVIE
One of the existing allocation schemes phase based prereplication method requires RAM up to half of the size movie in order to reduce the waiting.
The storage structures used to store movies in VoD server effect the number of concurrent streams and the waiting time. It stores number of movies, read them and feed them to users. One important component in VoD services is the design of video servers. Various models for the simulation of user behavior (and thus, of the load induc. To decide the size and location of the video servers and the location of videos in the hierarchy, the access behaviour of users must be considered. If a video is requested which is not available, this server contacts the next server in the hierarchy. The end-node servers store only a limited set of the overall available information which changes over time due to user interests. This architecture provides for cost efficiency, reliability and scalability of servers. If such a system is hierarchical, an end-node server handles the requests from a particular area, the next server in the hierarchy takes the request over for several end-node servers if those. Large scale video-on-demand systems require that the servers offering the video retrieval and playback services are arranged as a distributed system in order to support a large number of concurrent streams. The key idea of the proposed CAM approach is to time-compress the video stream, so that the interesting content is equally distributed (constant action) along the video. Video synopsis by constant action movie (CAM) offers a solution to this problem: The human operator only has to inspect (possibly) relevant parts of the video. Moreover, through the long irrelevant parts of the video material the attention of the operator decreases and therefore important events could be missed. Hence, most of the reviewing time is wasted. interesting content is sparsely distributed along the video. If the exact time of the incident is unknown, the material to be reviewed can be rather long and the examination becomes very time consuming. After any security incident occurred, the video material has to be manually reviewed by a human operator. Many existing security-systems consist of CCTV-Cameras, which record data streams and store it on a large storage medium.
