In the output image information based on image encoding equipment AVC encoding to compress information, you can obtain the GOP structure includes a hierarchical B image of the best reference relationship and is capable of performing random access is not instantaneous decoding refresh the image from the image of I. When performing a multi frame prediction, the memory management control operation command generating unit (13), is used for the image management of decoded image in the buffer memory management control operation command B image between a reference image and P image or I image registration for the reference image. When the B image between the P image or the I image and the reference B image is processed, the reference B image is placed first in the reference image list by reordering the command using the reference image list. When processing the P image or I image by using the memory management control operation command will long frame index maximum value is set to [0] and the reference image decoding long in the buffer is set to a non reference image. Performs random access from the I image that does not decode the refresh image instantaneously.
【技术实现步骤摘要】
【技术保护点】
一种图像信息编码设备,利用运动预测进行图像信息的编码处理而输出图像压缩信息,其特征在于,具备:存储器管理控制命令产生单元,该存储器管理控制命令产生单元通过对保存所述图像压缩信息的图像缓冲器中的所述图像压缩信息进行管理的存储器管理控制命令,将处于P图像或I图像之间、并参考所述多个图像信息的参考B图像登记为长期参考图像,将长期帧索引的最大值设定为[0],从而在对所述参考B图像进行解码时,释放从保存所述图像压缩信息的解码图像缓冲器解码出的所述参考B图像。
