Scalable video broadcasting apparatus and method over multiband satellite channel

An apparatus for receiving multiband broadcasting service using scalable video coding, the apparatus comprising:

• a multiband receiver for restoring packet streams from broadcasting signals transmitted through different frequency bands and combining the restored packet streams to restore a single transport stream (TS);
• a demultiplexer for splitting the restored single TS into scalable video streams having multiple layers and program specification information;
• and
• a video decoder for decoding the scalable video streams having multiple layers.

A method of transmitting multiband satellite broadcasting based on scalable video coding, the method comprising:

• scalably encoding video data to generate scalable video stream having multiple layers;
• multiplexing the generated scalable video elementary stream having multiple layers, compressed audio elementary stream, and program specification information to generate a transport stream (TS);
• and
• separating the TS into multiple TSs according to pre-given priority information and transmitting the packets using a different transmission band for each layer.
