The Design And Implementation Of Live Broadcast Assistant For Watching Together Live Type

With the current development of communication technology and people's demand for instant entertainment information,live broadcast is known to people year after year,more and more platforms introduce live broadcast services.Therefore,the live broadcast assistant for the anchor is becoming important.In order to build a usable and smooth live assistant,iQiyi designed and implemented a live assistant system on the computer.The initial version of the system mainly met the watching together type.The anchor can directly play the episodes from the iQiyi platform.It can add various sources to enrich the content of the live broadcast,and provide a more convenient route.In order to meet the needs of the anchor,this paper designs and implements the computer live assistant system.Taking the business purpose and indicators as the starting point and the user's needs as the core,we conduct user research,collect user feedback,draw persona,analyze and formulate interactive design in the early stage.The system is based on the RTMP protocol,which meets the real-time requirements.The system uses the RTMP protocol to send the encoded stream.Choosing a cross-platform Qt application development framework laid the foundation for system portability.The live assistant system is composed by the source management module,the work area module,the theater module,the barrage module,and the setting module.The work area module is responsible for managing the source and theater modules,and storing the source data.The barrage module is responsible for reading the barrage from the barrage server.The setting module is responsible for encoding and pushing the steam.The application is currently available at the iQiyi Live Center.The system improves the convenience of the anchor.The user test shows that the system can meet the easiness and high efficiency requirements of the anchor.
