摘要

PROBLEM TO BE SOLVED: To provide a communication controller which can lighten the load of multipoint communication control. SOLUTION: This communication controller has a data gathering part 140 which receives first data generated by encoding information at a first bit rate and second data generated by encoding the above information at a second bit rate through a communication line 3, a data selection control part 142 which selects one of the first data and second data according to at least one of the characteristics of the communication line 3 up to a transmission destinations and terminal devices 1051 to 105n at the transmission destinations, and a data synthesis and distribution part 141 which sends the selected data to the terminal devices at the transmission destinations.
