| Long-distance Video Monitor System was researched and designed by comparing with several different video monitor systems.Then Long-distance Video Monitor System was realized the common protocol and platform,based on Softswitch and Web Services.SIP protocol was used as common protocol,because it has been used a lot in network multimedia area and it became to one of the most famous protocol.Web Services was used as common platform,because it was one of the best distributed network platform,and it could be used to manage different kinds of client.In general,Long-distance Video Monitor System needs a wide bandwidth in network.However a wide bandwidth network pays lot money.So H.264 was used as a video encode arithmetic in this System for its great compress rate.The System design was including interfaces of Softswitch Server and Web Services,Software of monitor Client and Software of user Client.Unified Platform was designed by based on Web Services;Communication was achieved by based on SIP protocol;Video transportation was achieved by based on RTP protocol.The X264 was transplanted to DM642 platform to achieve video encode,which is one of H.264 algorithm.The video monitor system was validated with Softswitch Server and Web Services in our lab.The purpose of all this design was that video monitor could be used in all networks with the same Protocol and Platform. |
