Research On Multimedia Intelligent Terminal Platform For Big Data Applications

With the rapid development of Internet technology,new media technologies have been widely used.Many media companies have emerged.Multimedia terminals are everywhere in elevators,hairdressers,and shopping malls.The multimedia market has become an unstoppable trend.However,with many multimedia terminals currently,the limitations are still too large.Some are just offline playback,multimedia update and statistics are difficult;some are invested in the market,but it is difficult to know the operation of the terminal in real time;some use Windows system and H5 technology for multimedia playback,lack of flexibility,and interaction too difference.In short,most multimedia terminals have a single function,insufficient stability,and high limitations,which makes the development of multimedia terminal applications slow.A high-reliability and high-flexibility multimedia intelligent terminal platform architecture integrating multimedia publishing,intelligent hardware control and efficient real-time communication is designed and implemented in this paper.In this kind of platform architecture,an efficient network communication mechanism for two-way real-time interaction is proposed for the problem that it is difficult to grasp the terminal operation situation in real time.Aiming at the problem of single function,lack of flexibility and poor interActivity of multimedia terminals,a multimedia publishing design scheme combining Linux system and Android platform is proposed,which makes the terminal easier to integrate and software dynamic upgrade.The platform combines cloud services,database,Android and embedded platform technologies to solve the data interaction between the terminal and the embedded platform based on the JNI interface.The high-efficiency network communication mechanism based on the Netty framework realizes two-way real-time interaction,which makes up for the deficiency of the traditional Http protocol.It is more time-efficient and more stable.It makes the architecture scalable and easy to integrate with the features of the Android platform.Based on the platform,this paper implements multimedia publishing,terminal monitoring,intelligent access control and other functions,integrating instant messaging,face recognition and speech recognition technology.The multimedia terminal function is developed based on Android technology.The server is built and developed based on Linux system and JAVA language.Based on Mysql database and Redis database,the data is stored and cached persistently.Based on Nginx server,load balancing is implemented.At present,the multimedia intelligent terminal platform has been invested by a media company in Beijing.It has deployed more than 10,000 devices in major first-and second-tier cities in Beijing,Shanghai,Shenzhen,Hangzhou,Guangzhou,Nanjing,etc.,with good results,stable operation and strong scalability.And get better feedback.
