High-level system architecture for the delivery of dynamic IVVR (Interactive Voice & Video Response) services

Commercially available IVVR appliances [For example, DTG 3000 from Dilithium is a combination of MCU (Multipoint Control Unit), 3G-324M Gateway, and transcoder] still focus on dialog-based services and use VoiceXML to create IVVR applications that are generally IVR (Interactive Voice Response) Supplements, without sophisticated features like real-time video generation or camera-based interaction. This hinders the creation of advanced IVVR applications as mentioned in Section 4. Such applications are generally founded on pre-recorded or pre-generated video sequences that are played back based on speech commands or keystrokes. To create a more flexible solution that is capable of delivering games and interactive services, sounds, and graphics need to be generated in real time. The current research and testing results recommend the configuration featured in the figure on the left.

Adobe Flex has evolved into a suite of technologies appropriate for the creation of rich media applications and games. For the solution presented in this research, Flash is employed as the Game Engine as it is very flexible and can be extended to create 3D games [By using the open source real-time 3D Engine Papervision3D]. The Flash application is not run on a handset, but the audio and video it creates are transmitted over a 3G-324M session to a handset so they can be controlled based on the handset
