System Implementation Of Video Coding Based On IOS

Promotes unceasingly along with the development of 3G wireless communication technology and terminal equipment performance,video and become people like to exchange one of the ways,with respect to the text or photos,video can not only make from both better and comprehensive understanding of each other's dynamic process,with the sound of the rendering,more able to let viewers like the feeling of the scene,and increase the real-time.Video communication and display effect is far better than the traditional text or pictures,and retain the local and server video,you can download at any time to watch,restore the true picture of the time.This paper presents an online video transmission system of data encryption and decryption algorithm,ensure the relative safety in the process of transmission.Management system Web end users based on rule management and the management of data,the client user of audio and video transmission between friends by dialing telephone number,real-time communication file synchronized to the server.Video file management has two ways,one is based on the list of client management,one is based on the Web side of the way to manage.The specific research contents are as follows:First,according to different application scenarios,design and development of real-time video transmission and video transmission system encryption of data on the iOS platform.Research and implementation of video transmission network or mobile network,the realization of encryption and decryption algorithm of data security.Second,the development process and Xcode on the iOS platform software tool,analyzes the security mechanism of iOS platform,the implementation of encryption algorithm based on iOS platform,to ensure the data security during transmission.Third,comparison of audio and video encoding algorithm,using different network transmission protocol for data transmission.This paper compares the advantages and disadvantages of H264,JPEG,MPEG and other coding methods,according to the specific implementation results to select the optimal coding method for the system,and the use of UDP and TCP transmission protocol,such as transmission data.Security mechanism is designed and developed in local and wide area network and 3G network video real-time transmission system and data encryption in the iOS system,in various network scenarios to achieve real-time video transmission.
