Based On The Sip Protocol, Broadband Video Communication Terminal Design And Realization

As the continuously developing of multimedia technology and network technology,the technology of video communication over broadband has become the trend gradually.Many communications corporations have becoming the develop video communication products.We also decided to research and design the video communication terminal product based on sip protocol.This system adoptd Blackfin series ADSP-BF561 processor of ADI company to be the system core.The main function is to be responsible for handling each system responding event,moderating the communication between components in the board and codec of audio&video.In the project,we are closing around customer's requirement all the while. In addition to developping the IP video terminal product which have three core functions "IP video phone + web browser + stream video player",we has also cut out a new IP information terminal product which has low cost.I've finished these works in the project:Project managing and system architecturing;Organize the develop work of every subsystem;Be responsible for the designing and coding of streaming player subsystem;Guide the designing and coding of video communication subsystem.
