摘　　要：虚拟现实(Virtual Reality,VR)技术的快速发展,对视音频编码技术提出了更高的要求。从视音频编码技术在VR中的应用出发,探讨当前编码技术的局限性,如压缩效率不足、延迟问题以及交互性支持的不足。针对这些问题,提出了一系列优化理论和新策略,旨在提高编码效率、减少延迟,增强编码的交互性和实时性。提出适合VR需求的新型编码算法,并对算法优化、误差恢复和数据传输进行深入讨论,为VR技术的进一步应用提供理论基础和技术支持。The rapid development of Virtual Reality(VR)technology has put forward higher requirements for video and audio coding technology.Based on the application of video and audio coding technology in VR,this paper discusses the limitations of current coding technology,such as insufficient compression efficiency,delay problem and insufficient interactivity support.To solve these problems,this paper proposes a series of optimization theories and new strategies to improve coding efficiency,reduce delay,and enhance coding interactivity and real-time.A new coding algorithm suitable for VR is proposed,and algorithm optimization,error recovery and data transmission are discussed in depth to provide theoretical basis and technical support for the further application of VR technology.
