A technique is provided for high-efficiency compression of multiple video images having the same image pattern generated in different video formats. A video encoding apparatus AA that performs scalable encoding of an input video image instructs a video format converting unit to convert the input video image into a video image in another video format so as to generate a converted video image. Furthermore, an encoding-side prediction unit predicts information lost in the operation of the video format converting unit for generating the converted video image. A first encoding unit encodes the input video image using predicted results obtained by the encoding-side prediction unit. A second encoding unit encodes a video image converted by the video format converting unit. A multiplexing unit multiplexes the encoded results obtained by the first and second encoding units so as to generate a compressed stream b having video format scalability. |
