Design And Implementation Of Intelligent Set-Top Box Streaming Media Player Based On SAT-IP

In recent years,with the development of intelligent technology,intelligent terminal equipments are loved by the majority of consumers.The use of intelligent terminals to watch online video,playing online games has become a way of people's leisure and entertainment,in particular,Android intelligent set-top box with its home and openness has been the people's favor.At the same time in order to promote the development of satellite TV market,satellite TV signals through the IP network assigned to large multi-unit residential,enabling users to watch satellite programs in the intelligent terminal,a new communication protocol SAT-IP came into being.The emergence of SAT-IP protocol gives full play to the potential of intelligent device video playback,and it is expected to become one of the core technologies of future streaming media players.Therefore,the design and implementation of intelligent set-top box streaming media player based on SAT-IP protocol meets market development needs,and has realistic significance.In this paper,we designed a SAT-IP streaming media player in Android intelligent set-top box through Android application development technology,combined with SAT-IP protocol and streaming media technology.Through the IP network,the streaming media player as a SAT-IP client,is able to receive satellite programs and broadcast programs.The main structure of the streaming media player includes UPnP module,streaming media transmission module,source processing module and user interaction module.The main content of this paper includes:(1)In-depth analysis of SAT-IP protocol architecture and related technologies,including UPnP protocol equipment addressing,discovery and description,implementation of the RTSP session,and RTP/RTCP protocol data transmission mode;(2)From the point of view of user demand,this paper analyzes the application function of streaming media player.Based on the comparison and analysis of several real-time streaming media transmission schemes,combined with the hardware conditions of the Android intelligent set-top box platform,the overall design framework of the project is determined,and the functional modules are divided;(3)Realize the function of each module of the streaming media player.And the implementation process of each module and the way of communication interaction are given;(4)Test SAT-IP streaming media player.The test results show that,on the platform of Android intelligent set-top box,the player can broadcast satellite TV programs smoothly,and the user interface is simple,easy to operate.Design of streaming media player achieves the desired objectives.The design and implementation of the intelligent set-top box streaming media player based on the SAT-IP protocol has the following characteristics:the system is clear,the coupling between modules is small,the code is easy to transplant and so on.At the same time,the SAT-IP protocol can be further applied to intelligent devices.
