We present a novel visualization approach that extends the Sunburst technique to the third dimension, which allows for encoding additional data in the height of each arc segment. By stacking a number of such 3D-Sunbursts, we build a user interface for browsing collections of web pages. We apply techniques for web content indexing of multimedia data (text, audio, image, video) and text analysis ...

The Session Initiation Protocol (SIP) is a text-based protocol for initiating and managing communication sessions. The protocol can be compressed by using Signaling Compression (SigComp). Similarly, the Session Description Protocol (SDP) is a text-based protocol intended for describing multimedia sessions for the purposes of session announcement, session invitation, and other forms of multimedi...
