(57) Abstract: A coded signal separating apparatus, coded signal merging apparatus, coded signal separating and
merging system, and methods thereof capable of performing scalable transmission of image are provided. There
are provided a separating unit 1100, which is a separator separating means for separating a coded stream into a
basic coded signal B having a smaller code amount than the coded stream and a plurality of extended coded signals
E(m), which are used with the basic coded signal B to reconstruct an image, and a multiplexing unit 1600, which is
a separator multiplexing means for optionally combining and multiplexing the basic coded signal B with the
plurality of extended coded signals E(m) to generate a plurality of transmission coded signals St(1), to thereby
generate and output separated streams St(1), which are multiplexed transmission coded signals. Accordingly, when
they are used in a network, transmitting path selection according to a network status can be performed to realize
the scalable transmission of images.
