| With the rapid development of mobile smart devices,lot and other technologies,people’s family living standards have also risen steadily,and nowadays a great many family devices become intelli-gent.The distributed family entertainment system takes this as the background and is based on various smart devices in family life like smart TV,PC,stereos and so on,exploring a kind of entertainment system in which the smart phones and various family devices can cooperate with each others.Un-der this system,each smart device can exert its advantages and perform its duties.For instance,smart TVs have better audio-visual effects,and smart phones are light and easy to operate.Therefore,the distributed family entertainment system solves problems of interconnection of family devices,and en-ables each device to be fully used and exert its advantages.Another kind of popular technologies are AI technologies.Nowadays many aspects of life involve AI technologies,such as that face recogni-tion and speech recognition have stepped into ordinary families,but nowadays in distributed family entertainment systems,this kind of technologies has not yet been fully developed.However,with the improvement of software and hardware level,to perform AI computing on family smart devices has become possible.This thesis takes the distributed family entertainment system as the background and applies face replacement,vocal silencing and speech recognition technologies on this system.Combined with the actual background and scene,the main work contents in this thesis are as fol-lows:1.Since distributed family entertainment systems are not universal and the current standards are not unified,in this thesis we will propose and design a prototype system of the distributed family enter-tainment system.The prototype system is in a family local area network,including the interconnection and cooperation system between devices and media file services necessary for applying AI technolo-gies.2.Based on the design and implementation of the above contents,this thesis applies three kind of AI technologies.For technologies that cannot be directly implemented on this platform,in this thesis we will implement the corresponding data processing algorithms based on relevant technical princi-ples.During the process of prototype system design and implementation,it involves the application of Computer Network,Operating System,Android Development and other theoretical knowledge.Aiming at the present situation of relevant technologies,the technical features in this thesis are as follows:1.Currently,most AI applications are based on the Online pattern by network servers for computing,this thesis will take the Offline pattern,thus the AI computing will be executed by family devices,so we can explore the feasibility of related computing tasks on family devices.2.Some existing research contents or products are similar to those in this thesis,but most of them are closed source,thus security and other targets are difficult to verify.In this thesis the related technologies will be based on open source solutions.After the design,implementation and test of the entire prototype system and related functional modules,the functional and non-functional requirements in this thesis have reached the expectations,and the application of several AI technologies in distributed family entertainment system has been completed. |
