To improve the efficiency of media delivery over the Internet, a system and a method are provided for caching remote media files and retrieving cached media files, comprising hardware and software modules as well as steps for storing a remote media file into the cache and retrieving the cached media file based on a signature created by hashing only discrete parts of the media file. The signature is a key for finding the cached media files in the cache upon subsequent requests for the same media file, even if it is received from a different internet location. Media files may be adapted to the characteristics of different media clients, and adapted media files may be equally cached.

System and methods for efficient media delivery using cache

A method and system to trigger ingestion of remote content or playlists by a streaming server using URL folder mapping is disclosed. The streaming server maintains a URL Map having entries that map a URL folder referenced in the streaming URL to a content server folder located on the content server. This folder level mapping enables maintaining a many-to-many relationship between multiple content identified at the streaming server and their corresponding content located at the content server.

Method and system for performing fast channel switching in client-server systems, in which live media streams sent by a streaming server under the RTSP protocol are played by the client, are described. The existing functionality of the media player, for example seek functionality, is overloaded to provide switching between live media streams by using standard RTSP message in-band within a single RTSP session.
