コンテンツ配信システム、コンテンツ配信装置、コンテンツ配信方法およびプログラム
Document Type and Number:
Japanese Patent JP5817724
Kind Code:
B2
Abstract:
To provide a content distribution system for suitably controlling bit rate for each receiving terminal while reducing the number of probe packets transmitted toward the receiving terminals from a distribution device. A content distribution device which is mutually connected via a network to a plurality of receiving terminals has a content packet transmission unit for transmitting content data, a probe packet transmission unit for transmitting probe packets, a probe packet reception unit for receiving return packets from the receiving terminals, and a transmission control unit for determining the transmission intervals of the probe packets and the bit rate of the content data. In addition, the transmission control unit treats receiving terminals having similar time variations in the bit rate as a small group in determining the transmission intervals of probe packets to be transmitted to the receiving terminals belonging to the same small group together.
