Media RSS (MRSS) is an RSS extension that adds several enhancements to RSS enclosures, and is used for syndicating multimedia files (audio, video, image) in RSS feeds. It was originally designed by Yahoo! and the Media RSS community in 2004, but in 2009 its development has been moved to the RSS Advisory Board. One example of enhancements is specification of thumbnails for each media enclosure, and the possibility to enclose multiple versions of the same content (e.g. different file formats).
The format can be used for podcasting, which uses the RSS format as a means of delivering content to media-playing devices, as well as Smart TVs. Media RSS allows for a much more detailed description of the content to be delivered to the subscriber than the RSS standard. The standard is also used by content publishers to feed media files into Yahoo! Video Search, which is a feature of Yahoo! Search that allows users to search for video files.
None of the audio/visual content is hosted on this site. All media is embedded from other sites such as GoogleVideo, Wikipedia, YouTube etc. Therefore, this site has no control over the copyright issues of the streaming media.
All issues concerning copyright violations should be aimed at the sites hosting the material. This site does not host any of the streaming media and the owner has not uploaded any of the material to the video hosting servers. Anyone can find the same content on Google Video or YouTube by themselves.
The owner of this site cannot know which documentaries are in public domain, which has been uploaded to e.g. YouTube by the owner and which has been uploaded without permission. The copyright owner must contact the source if he wants his material off the Internet completely.
