Enrique de la Hoz - University of Alcala de Henares
His slides can be found on the Terena web site. The abstract for the session went as follows:
“In the last years, the interest about the video streaming over Internet has been increasing. There are some solutions based on open code that provide a good performance. Some of them has been tested during the last two years over the university campus network and after that it has been taken the decision of using a new system that increase the compatibility with the receiver platforms using RTMP (Real Time Messaging Protocol) and Flash Video to allow the conditional access to the contents based on user cryptographic credentials stored into a “cryptographic token” (USB device with hardware oriented cryptographic algorithms). ” - there , that told you didn’t it…
Problems with video in web have been about bandwidth, lack of common video formats, no standard delivery standards and users get lost in a multiplicity of formats
The arrival of Youtube introduced new ways if interaction with video content introducing a de facto standard based on flash technology, RTMP protocol etc This means that the flash payer plug is all that is needed and any device using this is able to play content. But there are still some problems – it is a proprietary scheme, there is no RTMP open specification and some of the codec as not free. This makes open source developments difficult. Adobe recently released a new version with RTMPE specification.. But there is still no consensus about DRM (digital rights management), it is not standards based.
‘They’ found three open source offers to develop an opens source flash player including Gnash, Open Source Flash Server has some disadvantages that restricts its use as video streamer.
They decided to build a solution that binds together a range of technological solutions most of which sounded like Sanskrit to me unfortunately…
