CONTENT DELIVERY SYSTEM

摘要

A content delivery system (100) comprises a user terminal (110), an application server system (120), and a connection control system (130). Before the transmission of a transmission request for establishing a connection for receiving content data, the user terminal (110) transmits a determination request for determination of a communication bandwidth to the system (120). The system (120) acquires terminal attribute information indicating the capabilities of the user terminal (110) on the basis of the determination request, determines a communication bandwidth on the basis of the terminal attribute information, and transmits the communication bandwidth to the user terminal (110). The user terminal (110) transmits a content transmission request including the received communication bandwidth to a system (130). The system (130) establishes a connection having the communication bandwidth included in the received content transmission request.
