Standards compliant

Extended user experience with real-time video applications

Network operators and service providers seek new attractive services which help them increase revenues and reduce churn. Handset manufactures can provide a better user experience and differentiate themselves from competitors by enabling their terminals with advanced video applications compliant to the latest standards.

3G-324M and IMS based Video Telephony

As experts in embedded systems and leaders in IP wireless technologies, fg microtec offers a Video Telephony application that allows full duplex communication in broadband wireless networks such as UMTS or Wi-Fi. The solution, fgVCC, is based on open standards adopted by the 3GPP for the IP Multimedia Subsystem (IMS). Non-IMS networks can also benefit from fgVCC.

fgVCC also supports the circuit switched version of the Video Telephony service according to the 3G-324M terminal capability definition as specified by the 3GPP. This way, the service provider ensures a smooth migration between the existing 3G- 324M solution towards the future IMS based one, being able to combine both seamlessly for customized services.

See-What-I-See

As an example of the benefits of combining circuit switched and packet switched services, fgVCC provides a 'See-What-I-See' application that allows the sharing of live video streams between mobile users while talking to each other over a GSM or UMTS circuit switched connection. These video streams are captured by the phone's camera or simply taken from video files stored in the phone's memory.

See-What-I-See is an innovative video sharing application that enables users to extend their ways of communication. Since it operates in half-duplex mode and it does not requires simultaneous audio transmission over the IP network, it can be easily deployed by operators in 2.5G networks like GPRS or EDGE.

Based on fgIMS Multimedia Framework

fgVCC is fully integrated in fg microtec's IMS Framework (fgIMS). This framework allows the terminal manufacturer to easily integrate and develop multimedia services in the handset. All IMS basic functionalities such as registration, authentication, session management and multimedia control are provided by the framework, together with an adaptation layer for the specific target system and OS. fgVCC can be ported to any target plattform in a matter of days, thanks to the fgIMS concept. Only certain extensions for the circuit switched Video Telephony service are necessary. For the packet switched based applications, all necessary protocols are already provided by the framework (e.g. SIP, RTP, Media Controller, etc.).
