摘要
在网际互连协议(Internet Protocol,IP)化终端应用中,超高清音频传输存在编解码处理复杂、网络环境多变的问题,导致传输延时与数据丢包问题频发、编码标准与网络协议匹配性不足,成为制约传输稳定性的主要因素。对此,围绕编解码机制、端到端自适应码率调控策略以及多通道音频流的同步缓冲技术展开研究,构建适配不同终端环境的动态控制模型。通过分析传输过程中的关键干扰因素,明确编码延时、数据拥塞及信号同步失衡的成因。此外,在多平台IP终端部署优化方案,结合现行音频协议的结构特征提出兼容集成路径,以提升音频还原度和传输效率。研究成果对IP音频系统高质量输出构建具有参考价值,尤其适用于对实时性要求极高的远程传输场景。
In Internet Protocol(IP)-based terminal applications,ultra-high-definition audio transmission has problems such as complex codec processing and variable network environments,resulting in frequent transmission delays and data packet loss,as well as insufficient matching between encoding standards and network protocols,which has become key factors restricting the stability of transmission.In this regard,research is carried out around the codec mechanism,end-to-end adaptive bitrate control strategy,and the synchronous buffering technology of multi-channel audio streams,and a dynamic control model adapted to different terminal environments is constructed.By analyzing the key interference factors during the transmission process,the causes of encoding delay,data congestion and signal synchronization imbalance are clarified.In addition,an optimization plan is deployed on multi-platform IP terminals.A compatible integration path is proposed in combination with the structural characteristics of the current audio protocols to enhance audio fidelity and transmission efficiency.The research results have reference value for the construction of high-quality output of IP audio systems,especially for remote transmission scenarios with extremely high real-time requirements.
