随着移动互联网的不断发展,移动终端上的各种语音、音乐的应用需求变得越来越重要.然而由于移动网络的服务质量以及无线信道的通信效率下降导致接收终端所获得的数据对比发送端出现丢帧或误码失真情况,造成人耳听觉质量严重下降,迫切需要对多媒体接收终端的语音、音乐信号的丢帧隐藏技术进行研究.本文针对国内外学者们目前在研究的移动音频丢帧隐藏技术的热点问题,重点分析了目前主流移动音频编码器标准AMR-WB+和AVS-P10所采用的丢帧隐藏算法,指出两种丢帧隐藏算法存在的不足,并且提出了丢帧隐藏技术今后的研究和发展方向.
With the continuous development of the mobile Internet, the application requirements of various voice and music on the mobile terminal have become more and more important, however, the data obtained by the receiving terminal is sent in contrast due to the service quality of the mobile network and the decrease of the communication efficiency of the wireless channel There is a frame loss or bit error distortion, resulting in a serious decline in the quality of human hearing, there is an urgent need to multimedia receiver terminal voice, music signal lost frame hiding technology.This paper aims at domestic and foreign scholars are currently studying mobile audio loss This paper focuses on the hotspot issues of frame concealment technology and focuses on the frame loss concealment algorithms currently used in the mainstream mobile audio coder standards AMR-WB + and AVS-P10. It also points out the shortcomings of the two frame loss concealment algorithms and proposes a frame loss concealment technique Future research and development direction.
