Helix Media Library User GuideIntroductionThe Helix Media Library [HML] is designed to make it easy for you to upload existing mediacontent like AVI, MPEG, QuickTime, WAV etc and for these to be encoded for streaming delivery,currently RealMedia, H.264/AAC and MP3 in a Flash player.The content can be viewed from within the HML site, or embedded into external sites (a VirtualLearning Environment for example) so users are not required to login directly to the Library andfrom mobile devices such as the iPhone.HomepageWhen you have successfully logged into the HML you will be presented with the home screen,similar to the image shown above.The home screen is made up of the toolbar, latest media, random viewable content and categorylisting.3

ToolbarThe toolbar offers a number of options:‘Home’ will bring you back to the main page from any point.If you have media to add to the service and have been granted sufficient privileges to the system,clicking ‘Upload’ will take you to the 'add media wizard.Preferences allow you to change between the supported player types at any point. Currently youcan select from RealMedia or Flash; this affects both audio and video.Help will offer basic guidelines to the use of the system, plus any specifics added by youradministration team.The search box will allow you to discover items based on media title, description, keyword orcontributor.The login section allows registered users greater access to the system, such as upload rights. Enteryour credentials in the provided fields as shown. Selecting ‘Remember Me’ will avoid thisprocedure on return to the site. This is not recommended on publically accessible machines.SidebarThe sidebar shows all categories you are able to view. Selecting a category will display a list similarto the one shown below. Simply select a thumbnail to view the content.With iTunes U integration enabled, categories that offer the function will show a link to theiTunes U page of the institution for quick access to content via that program.4

Helix Media Library User GuidePlayback and EmbeddingAt the home screen, clicking on a thumbnail (or double clicking on the Latest Media carousel) willtake you through to the media playback page. Similarly, selecting a category will bring up themedia list for that section, again click the thumbnail or title brings up the viewing page.1. Video playback, in either RealPlayer or Flash Player (shown)2. Copy URL: Displays a link to this page allowing you to highlight and copy the link.3. Copy Embed Code: Displays the code required to embed media into another web page.4. Quality: Select high or low quality dependant on your bandwidth. Relates to both audioand video playback.5. Download: When enabled, offers users the option to download the media clip.6. Inappropriate Content: Report the media clip to the system administrator. The clip willbe hidden from view until approved by the administrator.7. Related Clips: Links to video within the same category or related meta-data.8. Tags: Lists the meta-data tags used by the current media clip9. Comments: Read and enter comments about the current media clip. Offensive contentcan be reported, and will be hidden from view until approved or deleted by anadministrator.5

Copy URLThe ‘Copy URL’ function provides a link to the media player page itself. Just highlight the URLand press CTRL + C or right-click and select Copy to place it in the clipboard.Copy CodeRealMediaThe Copy Code function generates HTML code that allows you to embed the media player intoand external page or Virtual Learning Environment course. This applies to both audio and video;we will cover video in this section.The code is generated based on the current settings of the media playback page. For example, inthe above screen shot a High Quality Real video is currently selected; this would generate thefollowing code:To use the code within your own embed page, highlight the text in the Copy Code text-box andpress CTRL + C or right-click and select Copy. This will place the code within the clipboard.Within the tags of your webpage or blank work area of a VLE course, press CTRL +V or right-click and select Paste, to place the code.6

Helix Media Library User GuideAs you can see, emphasized within the code as WIDTH and HEIGHT attributes. These are theonly areas you should change in general use. Where width and height are highlighted, changeboth accordingly, usually no higher than 640x480.Where width only is highlighted, change the value to match that of the previous changes.When embedding audio you can ignore the width and height requirements in most cases, unlessyou are specifying an image to display in the Flash player.Flash MP4The embed code for the Flash player is far simpler, with one caveat on the playback size of thevideo. The code below shows a typical embed object that can as before be pasted into a web pageor VLE module.Again the emphasized section shows the width and height attributes that can be modified. Asbefore, it is inadvisable to set the video size above 640 [width] x 480 [height].In this example to set the video playback window at 640x480 change both width attributes to 640,but you must change the height attribute to 505. This is required to allow room for the playercontrols (start/stop etc) to be displayed correctly.In all instances of changing the default sizes always add 25 pixels to the height of your chosenvideo size.7

Inappropriate Content ReportingSelecting Flag as Inappropriate will display the below screen.From here you may select the subject of your concern from a drop down list.Enter a message describing your concern and the reasons you wish the media to be removed. Asystem administrator, who can fulfill your request or reinstate the content, will moderate this.You will be notified of the outcome at the administrator’s discretion.Content flagged will be removed from view immediately.CommentsWhen comments are enabled, users are able to leave 100 character messages about the content.Any comments deemed inappropriate or offensive can be reported to the administrator. Reportedcomments will be hidden immediately.If an administrator or moderator confirms the reported comment as appropriate to the content,the comment cannot be reported again.8

Helix Media Library User GuideRSS FeedClicking the RSS button within a category will display the Really Simple Syndication [RSS] feed.This allows a user to subscribe to a basic feed, updating automatically whenever new video oraudio is added to their chosen category.When a feed is chosen, you will see a preview of the content to be delivered. The screenshot belowshows the Firefox browser previewing the content.The RSS feed link can be added to any compatible viewer such as the RSS Feed Reader built intoWindows Vista or Windows 7.9

Adding MediaMeta DataClick on the Upload tab. Users with standard access rights will be shown the below screen.You will need to provide a title and description; these are compulsory fields. Dependent on yourupload rights, you will be able to select a number of categories to upload to, in most cases it willdefault to the corresponding faculty/school/department you are in.Provide an email address to be notified when your media is ready.Tagging media uploads allows you to relate content to certain areas. For example, adding a Sporttag to a number of uploads will group that content in a relationship that can be easily searched.You may be asked to agree to a disclaimer in some circumstances when uploading media. This willbe dependent on rules set by the site administrator.Selecting Next will bring up the file selection screen.10
