    • A digital signature apparatus including, a converting unit that converts, based on a first video image frame being independently replayable, a predicted frame being not independently replayable into a second video image frame being independently replayable, an encoding unit that encodes the first or second video image frame into an image data according to an image format, a transfer unit that transfers, when receiving the predicted frame, the predicted frame to the converting unit, and transfers, when receiving the first or second video image frame, the received video image frame to the encoding unit, and a digest information generating unit that generates a digest information for each of image data encoded by the encoding unit.
    • 一种数字签名装置,包括:转换单元,其基于独立地可重放的第一视频图像帧,将不能独立地重放的预测帧转换为独立地可重放的第二视频图像帧;编码单元,其对所述第一或第二视频进行编码 图像帧根据图像格式转换成图像数据;传送单元,当接收到预测帧时,将预测帧传送到转换单元,并且当接收到第一或第二视频帧时,传送接收到的视频图像帧 以及摘要信息生成单元,其生成由编码单元编码的每个图像数据的摘要信息。
