Distribution control, method and system for changing a parameter of reproduction quality at a communication terminal based on the received transmission delay time information

摘要

A distribution control system distributes data to a communication terminal through a communication network. The distribution control system includes a receiver configured to receive, from the communication terminal, transmission delay time information indicating transmission delay time from when the data is distributed by the distribution control system to when the data is received by the communication terminal; and a changing unit configured to change, based on the transmission delay time information received by the receiver, a parameter of reproduction quality when the data is reproduced by the communication terminal.
