Now that we had all of our media files in one location it just came down to the delivery method and media library look and feel below you can see a screenshot of our media library

This gateway page is made up of basically 3 elements the media document library a search box and a recently added list. The only thing left to add was the delivery method, this could have been a list with hyperlinks to the videos but the best solution we found was ASX files and example of which can be seen below.

Using ASX files allows you to download the file and place on any part of the gateway where if we had used a links list we would have had to rewrite the link every time we needed to place a wrapper file anywhere else on the gateway. This also allows us to track our video resources as I stated in a previous post we numbered the videos rather than name them so as long as we maintained backups of the ASX files and video files both could be tied together. We can also tag the ASX files to help with the searches for end users a good example of this was an old Betamax video with a Volvo car in which all staff knew had a Volvo car but could never remember the title. The ASX file method would also allow hosted solutions of SharePoint to stream their own videos as the wrapper file can point to an internally hosted Windows media server but the ASX files reside on the remote server.

 The next problem was backup and restore for us this is a two part process with the ASX files being backed up on a nightly basis as well as the rest of the SharePoint farms content with Avepoint Docave and with the video files we backup once a month using Symantec backup exec. We chose once a month simply because of the size and length the job takes to run (Currently three days) the most videos we would lose are around about 20 so not a total disaster.

I hope you have enjoyed this three part series on streaming media if you have any questions you can always ask through comments on the site.

As I said in a previous post I would cover media streaming and how we deliver all of our digital assets through SharePoint, in the presentations that we give on our learning gateways this subject always gets a good reception as this is a great way to engage staff in the whole gateway experience. Before I get into details I thought I would take you through the media streaming journey.

 What we deliver through SharePoint now is version three of our digital media gateway this all started with the release of windows server 2000, media services was one of those hidden gems that Microsoft never seem to talk about this was not the main reason there where so many other advantages to moving from Windows NT 4 too Server 2000 with active directory and group policy deployment high on the list of big wins. So we put media services on the back burner until the release of windows server 2003 at that time is was a much more mature technology but still very much unknown. But it was not until 2005 that we started digitizing all the video tapes in the school this came about with the news that Dorset County Council where reroofing the main block during the summer holiday of 2005 this is where our server room and majority of IT suites are so I had to find work to cover us during this period.

 After much research we decided to purchase seven pinnacle studio movie boxes this gave us the ability to connect to any video recorder or DVD player through a scart lead I also purchased seven video recorders from comet (I am sure the salesman thought I was mad) and a Dell server with 8 drives bays giving us in excess of a 1 TB of local storage on the server. The call went out to staff for their departmental videos in early July and hundreds of tapes turned up we then divided up the tapes and with the help of the techies Christian Drewson, Sylvia Haghighi and Dan Rolles also family members we started the mammoth task of digitizing the schools video stock. After six weeks we had managed to get over a 1000 online this was delivered through an HTML website on the media server. With the arrival at Twynham of Darren White we did take the next step and Darren wrote a PHP website allowing us to make the delivery of digital assets to staff more automatic. But it was the next step that was our biggest leap delivery through SharePoint which I will cover in the next post……
