这份报纸建议编码方法改进传动表演的不相等的误差保护(UEP ) 三维(3D ) 基于扩展窗户喷泉(EWF ) 听觉。与有相等的错误保护(EEP ) 的另外的传播不同当播送 3D 时，声音反对。提取重要听觉的目标的一条途径被介绍，并且更多的保护被给更多的重要听觉的目标，比较地，更少的保护被给正常听觉的目标。客观、主观的实验证明了建议 UEP 方法比相等的错误保护方法完成更好的性能，当重要听觉的对象的位错误率(BER ) 能从 10 ^-3 减少到 10 ^-4, ， UEP 的主观质量比在 14% 的 EEP 的好时。

英文摘要：

This paper proposes an unequal error protection（UEP）coding method to improve the transmission performance of three-dimensional（3D）audio based on expanding window fountain（EWF）.Different from other transmissions with equal error protection（EEP）when transmitting the 3D audio objects.An approach of extracting the important audio object is presented,and more protection is given to more important audio object and comparatively less protection is given to the normal audio objects.Objective and subjective experiments have shown that the proposed UEP method achieves better performance than equal error protection method,while the bits error rates（BER）of the important audio object can decrease from 10~（–3） to 10~（–4）,and the subjective quality of UEP is better than that of EEP by 14%.
