For hundreds of thousands of years human beings communicated using sound and sight The phone invented in 1876 limited
people to voice communication
A hundred years later limited visual
communication becomes available
over ISDN lines
Still no critical mass for visual communication Today – Critical mass is around the corner

New Communication Paradigm Critical mass to Visual Communication
3G provides the high bandwidth High bandwidth enables high quality visual
communication Key issue for high bandwidth is visual
communication and content
3G Means Visual Services

Challenges for the vendors
Enabling customized and off-the-shelf applications of VAS
Providing network APIs towards partner application providers
Hiding the details from the application and user Signaling protocols (RTSP, 3G-324M, SIP, RTSP, H.323, H.320..) Media type (Codec, bit rate, resolution, frame rate…) Interoperability issues (vendors, models, software versions…)
Providing application primitives Call control (initiate session, disconnect, authorize etc) Media Processing (Picture in Picture, Text Overlay etc) User Interaction (DTMF, UI etc) Managing and Scheduling of resources (bandwidth, platform resources etc)

Challenges - cont’d
Modularity according to the required functionality Utilizing different network components:
• a gateway if protocol/network conversion is required• real time audio and video processing blades if required• network access elements (e.g. ISUP) if required
Scalability Support for thousands of concurrent sessions Just add components to scale up No Chassis size limitation Entry level systems
