g. © 2009 by Taylor & Francis Group, LLC SIP: Advanced Media Integration Experimental Results The advent of high-speed fiber-optic networks has increased the capacity in bandwidth and the current supported high speed consolidates them as the ideal medium for high-bandwidth transmissions. Currently, the real-time transport of high quality video over IP has been successfully tested in research networks expanding the range of video formats to be used on IP networks and the improvement of new high-quality video services. Real-time transport of high-quality live video is one of the main current efforts in innovation and research of next-generation Internet organizations, such as the i2CAT Foun- dation. In i2CAT, a SIP-CMI testbed has been implemented as an add-on of its SIP platform (SIPCAT). The first one has provided the SIP-CMI subsys- tem and the second one, the SIP infrastructure. In the following, several examples of real experiences are outlined, focusing on the concepts that have been explained previously in this chapter. 2.7.1 Example of Advanced Service: On-Line Transcoding The goal of the platform is to deploy a system through which users can access high-quality contents from their terminal, regardless of its characteristics, by interacting with different modules in a transparent way from the users' point of view, by using Web services and SIP services. Within this context, a content transcoding module was developed using the SIP-CMI approach. The main functionalities of the transcoding module are to provide: Real-time transcoding, in order to adapt to user specifications or QoS network limitations Full information for transcoders and media servers A list of available resources, such as high-quality videos or different coding schemes, among others Resource updating and inserting mechanisms In order to develop this transcoding module, it has been necessary to imple- ment different service elements and deploy the SIP-CMI platform to validate them.
