A dynamic frame discard strategy is proposed at the encoder is proposed,which discards the frames correlated to others based on scene change detection,and u.
该文探讨适合于中低码率无线信道应用的一种方法:在实时编码的初期,通过量化QP(quantization parameter)值的调整,来满足信道带宽的要求;当信道变差时,在编码端采取动态丢帧策略,通过场景切换检测,将相关性强的帧丢失,在解码端通过双线性时序插补方法,恢复丢失的帧。
In this paper,a scene change detection method with little additional calculation is proposed,as well as a scene change processing algorithm which adjusts the quantization parameter of the first P frame in the new group based on group re-division mechanism.
为有效解决该问题,提出了一种附加运算量很小的场景切换检测的方法,以及在图像组(GoP)重新分组的基础上对新GoP第1个P帧的量化参数加以调整的场景切换处理方法。
