How to Build a "Lean and Mean" Video Gateway Using 3G-324M-over-IP
Video-based applications in the mobile network are one of the main drivers for the deployment of 3G networks. Both the 3GPP and 3GPP2 standards organizations have adopted the 3G-324M protocol as the primary means of transporting conversational video over mobile networks.
Traditional video gateways bridge the representation of video in the mobile network (3G-324M) and the representation of video in the IP network (video/voice over RTP). They have substantial disadvantages, however. This white paper discusses the role of 3G-324M-to-IP video gateways in mobile video applications and introduces an alternative approach, called the "lean and mean" video gateway. It presents basic implementation guidelines and describes the approach's significant advantages.
