Abstract: Provided is an apparatus and method for transmitting/receiving multiband broadcasting using scalable video coding, which can solve a limitation of a transmission band in a multichannel satellite broadcasting service and increase availability of a satellite broadcasting service by scalably encoding video data and transmitting the data using a different transmission band for each layer. The apparatus for transmitting multiband broadcasting using scalable video coding includes: a scalable video encoder for scalably encoding video data to generate a scalable video stream having multiple layers; a multiplexer for multiplexing the scalable video elementary stream having multiple layers, a compressed audio elementary stream, and program specification information to generate a transport stream (TS); and a multiband transmitter for separating packets of the TS into multiple TSs according to pre-given priority information and transmitting the packet streams using a different transmission band.
