<p><P>PROBLEM TO BE SOLVED: To provide an image encoding device capable of facilitating a random access in a decoding device in an MPEG-forth-generation video encoding specification. <P>SOLUTION: An encoded image frame is inputted (S401), and when an encoding type is intra (S403), an NAL unit including a parameter set is generated and outputted (S404) prior to the output of the NAL unit of slice data (S407), and the NAL unit including absolute time information is generated and outputted (S405). On the other hand, when the encoding type is any type but intra, the NAL unit including relative time information is generated and outputted (S406). <P>COPYRIGHT: (C)2004,JPO</p> |
