You can find via the tv.funet.fi media-archive multimedia assets that are avalaible from CSC and it's collaborators. Most of them are primarily aimed for online viewing in the universities which have high speed internet connections. Viewing of the content may require installation or upgrading of streaming video players. Examples of the most common players are Flash Player, Realplayer, Quicktime player, Windows Media player and VLC.

The old SGI Mediabase server has been retired as an option in medar. It's MPEG1 and MPEG2 assets are used as archive file formats and they have been converted to Realvideo and/or MP4 for streaming. Currently the preferred streaming format is H.264 video codec and AAC audio codec in a MP4 container. The default streaming protocol is RTMP which is supported by the Adobe Flash Player plugin in most Web browsers. The links in the Formats section may also point to elsewhere than mediaservers. For example presentation material might be available as downloadable files or html pages.
In the Funet-TV media-archive, which has been implemented with the Medar-software developed at CSC, we have stored metadata on multimedia assets that are available via CSC or our partners. Most of the assets are in the realvideo or MP4 format which are streamed from dedicated media-servers but also references to web pages with multimediacontent can be found in our archive. The contents of the media-archive can be searched in many ways, including custom searches designed for browsing.
The media-archive uses the Lucene search engine. Examples of common queries are shown below. If not mentioned otherwise the query searches over at least the name, abstract, description, keywords and the names of persons and organizations. the search terms should be written in lower case and operators like AND and OR in capitals.
The following browsing alternatives have been predefined under the freetext search box:
The search results are first organized by their aggregation (hierachy) level which means that first come different folders and only after them individual videos and other subentries. Depending on the listing in question the second ordering criteria is either alphabetical or cronological. Folders have their own icon and videos usually have a small icon created from the video itself. The date in the listings is the creation date of the asset. Language is described with the standardized language codes (e.g. fi=finnish, en=english, sv=swedish). Longer listings are divided in subpages that can be reached by selecting the desired page number from the blue bar. The currently active page is shown inside square brackets.
By selecting the title of an asset one reaches the page showing the basic details of the asset. This page usually has a keyframe extracted from the video on the right and other information on the left side or below.
At the upper left hand corner the title is shown in a larger font than other text. In some cases an alternative title may shown under it in italic. Under the title are the names of the creators or main figures like the lecturer. Possible organization affiliations of the persons can be shown by selecting "full details", see more on that below. Otherwise an organization is shown on this compact basic display only if the organization (e.g. CSC) is considered as the creator and not an individual person.
The formats field lists describes in what forms and where the assets described in the page are available. For example real format means streamed video that can be watched with the realplayer software. mpeg-1 (mediabase) means streamed mpeg-1 format video that requires the mediabase player software for viewing. Quicktime accordingly requires the quicktime player. WWW or html designates a link to a web page with more information. Information about the most common mediaplayers and their installation can be found in our help section.
Other basic information includes the language used in the presentation, if any, the type of the asset, duration (hh:mm:ss), keywords and possible references to further information, creation date which is usually the shooting day and a possible information on a new version that has superceded this one. After these fields comes a chapter in italic which is the abstract and which can be followed by a full description. A subset of XHTML is available for the fulldescription, thus it may look like part of a web page with hyperlinks, images, tables etc. even though it's part of the metadata description.
The bottom part of the page shows possible information about copyrights. If the copyrights are not explicitly mentioned, please contact Funet-TV if non-commercial use directly from our servers doesn't meet your requirements. The final field, if present, points to the collections this description is part of like the course folder or the web-pages of some conference where this was presented.
The "full details" selection from the blue bar shows a variable amount of additional details. These can include information about the organizations persons are affiliated with, cast with their rolenames, publication date, version and source information, identifiers, various technical details etc. The selection of elements presented may easily be changed in the future as seen necessary.
Those who are technically interested in the underlying metadata can get the comprehensive listing of the enhanced Dublin Core format in XML-syntax by selecting the XML option in the blue bar. Those who are interested in detailed description of the format can follow the link at the bottom of the page that points to the metadata schemas used.
