Kommunikationsverarbeitungsvorrichtung, Datenübertragungssystem und Verfahren für Kommunikationsverarbeitung

摘要

A communication processing apparatus that acts as a server (200) for transmitting data to a client (300) includes a data transceiver (204) configured to carry out communications with the client (300), a rate controller (210) configured to control a bitrate of data transmitted to the client (300); and a data processor (202) configured to prepare data to transmit in accordance with the bitrate. The rate controller (210) includes a throughput calculator (211) configured to extract an effective data transmission and reception period not including an ineffective data transmission and reception period in a period during which a communication connection is maintained between the server (200) and the client (300), and to calculate a maximum throughput on the basis of the length of the effective data transmission and reception period and the amount of data transmitted; and a bitrate setter (212) configured to set a bitrate within a range of up to a maximum allowable bitrate corresponding to the maximum throughput calculated by the throughput calculator.
