摘要： A transmitter apparatus used in a video distribution system includes: first encoding means configured to output a first stream in multi-stream encoding; second encoding means configured to output a second stream in the multi-stream encoding; and multiplexing means configured to multiplex and output the first stream and the second stream. The first encoding means outputs encoded data obtained by encoding a main video image as the first stream. The second encoding means outputs encoded data obtained by encoding a partial presentation area to be presented by being added to the main video image as the second stream.
