| Abstract: | In this paper,the design principle and the realization method of video transmission and processing based on internet are discussed in detail.In this design,in order to improve resource and networking band with utilization ratio,the authors put forward the method that VBR become s dynamic CBR in networking communications,at the same time ,by feedback mechanism contacting encode with channel,transmission and receive effectiveness.And it adopts the way of encode combine with decode,priority control and virtual channel transmission.So this system reaches true self-adaptation control. |
