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.

The user guide for the Funet-TV media-archive

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.

Browsing

The following browsing alternatives have been predefined under the freetext search box:

Latest entries
Shows 20 latest entries in medar. This is based on the "published in database" timestamp which can be seen at the end of the "full details" listing of each particular entry. The date shown in the listing is the creation date which is most of the shooting day of the video itself.
Program title
Lists all entries in alphabetical order according to their title field (dc.title)
Person
Lists all separately entered persons in the medata descriptions alphabetically by their family name. There's no attempt to even try to decipher and extract family names that are in the middle of descriptions or to do face recognition. All names are from the separately entered creator, publisher, contributor or cast elements that may not contain all persons involved in the making of a particular video.
Organization
Lists alphabetically all separately entered organizations as well as organization that may have been assoticated with persons.
Series title
When a series of entries form a collection like all presentations on a course or a conference they are usually stored in a common folder with a separate description. In search results they are marked with a special folder icon. Thus this is a listing of all those folders.
Producer
Listing of producers or other entities responsible for the publication of the assets described (dc.publisher)
Keywords
Keyword listing contains all terms specifically entered as keywords. They are mostly without a governing schema and in the language used in the asset itself. The freetext search does also include words picked from descriptions and titles but they would be too numerous for this kind of listing.
Date
Here the entries are organized in monthly categories according to their creation date. Those descriptions, e.g. course folders, that in reality span over several months are generally catalogued under that month which they were finished.

Search results

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.

Asset information page

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.

Title and creator information

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.

Fictitious information from our full description validation document

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.
