Research On Broadcasting New Media Listening And Interacting Based On Streaming Media Technology

With the streaming media technology in the mobile terminal broadcast function is increasingly mature,the use of mobile phones to listen came into being.In order to meet the needs of the audience to listen to the radio program at the mobile terminal,this dissertation develops a mobile radio system.In this dissertation,the overall architecture of the system is studied,the application of the client and the HLS protocol and the development and design of each module of the background service are studied.“JRadio” system using MVC development framework in software and data transmission and processing business divided into layered structure,the mutual connection between the layers,but do not interfere with each other,reduce the coupling.Server hardware uses the distributed deployment mode,which improves the load capacity of the system,optimizes the allocation of resources,and also facilitates the future expansion.The development of the client of mobile terminal operating system iOS and Android two based on mainstream,solves the problems in listening to the webcast on PC only,will listen to move to the mobile phone terminal,increase the user's way.The audio and video stream using HLS protocol,HLS protocol to solve the multimedia stream transmission cross platform,multi rate problems,can be compatible with mobile streaming demand.Under the premise of ensuring the quality of audio and video,through the use of H.264 video coding format and AAC audio coding format,improve the system of audio and video encoding and decoding ability,save computing,storage and transmission resources.Follow the system database design database design commonly used in the field of three paradigms,under the regulation of the database design to avoid the emergence of a table,and not in the table primary key attribute and an attribute may appear in more than one table in the situation,to enhance the performance of the database.Listen to the development of the system,to achieve a new way of listening to the radio program,expanding the influence of the broadcast,opening up the broadcast program in the field of mobile media.
