With the rapid development of Mobile Internet and the mature of 4G networks

mobile video service has gradually become the mainstream service.While mobile video has become the peak point which internet players race to control

for operators

how to take strategic position in this domain should be deeply considered.This research is based on the network itself primarily

researching a series of technical means such as video sensing monitoring

caching

dynamic transcoding

etc.in the 4G environment

then establishing video optimization and quality assurance system.On this basis

the study explore constructing AAC architecture complying with 3GPP standard

opening network Qo S capability

combined with PCC function

to internet players via standard interfaces.Therefore operators participate in the process of video traffic scheduling

and thus foster the capability to share business value chain.
