本文提出了一种ＨＤＴＶ视频显示缓存器管理方案，此方案依据不同帧类型采用相应对策管理ＨＤＴＶ视频缓存器，并以ＡＨＤＬ语言描述的状态机的方法实现。该方法在我们研制成功的ＨＤＴＶ视频解码功能样机中采用，取得了较好的效果。 This paper presents a HDTV video display cache management program, which program based on different types of frames using the corresponding measures to manage HDTV video buffer, and to AHDL language described state machine method. This method is adopted in the HDTV video decoding function prototype that we have successfully developed and achieved good results.
