| 摘 要： | 本文针对机载图像实时压缩的应用需求,讨论了一种H.264编码器性能的评估方法.该方法以典型的机载视频画面为测试序列,对编码器设定一组恒定QP值进行编码,将压缩后码流比特率与标准算法对比,评判编码器性能的优劣.通过对三种不同编码器的测试对比,证明了该评估方法的有效性.

| Abstract: | For the demand of real-time video encode in airborne applications, a method ofH.264 encoder assessment is discussed, which is based on constant QP encoding using airborne video sequence. The bitrates of encoded stream is compared with referenced encoder, and the performance is assessed. This method is validated by the test and comparison of three different encoders. |
