摘要
AV1是目前国际上最先进的视频压缩标准,该标准有着较高的压缩效率。文中首先介绍了AV1的解码流程,其次重点阐述了CDEF滤波器的处理流程和物理意义,并给出了CDEF滤波器的ASIC实现。该实现可集成在AV1视频编解码芯片中,以应用在安防、监控、机顶盒和平板电脑等领域,有较高的工程应用价值和商业价值。
AV1 is the most advanced video compression standard in the world,which has high compress-ion efficiency.Firstly,the decoding process of AV1 is introduced.Then,focusing on the processing process and physical significance of CDEF filter,the ASIC implementation of CDEF filter is proposed.The implementation can be integrated into the AV1 video codec chip for application in security,monitoring,set-top box,tablet computer and other fields,and has a high engineering application value and commercial value.
