Transmission system, reception system, and transmission and reception system capable of displaying a scene with high quality

摘要

A full-scene storage portion stores full-scene BIFS data and if a BIFS command other than Scene Replace is received from an encoder a full-scene composition portion composites the full-scene BIFS data stored in the full-scene storage portion and the BIFS command together to generate new full-scene BIFS data and update the full-scene BIFS data stored in the full-scene storage portion and periodically or if a reception system issues a transmission request the full-scene BIFS data stored in the full-scene storage portion is transmitted to the reception system. Thus a scene can be displayed with high quality.
