Abstract

[Problem] To transmit and receive well-balanced high-quality data when communication is performed between transmission terminals via a relay device. [Solution] A transmission device transmits and receives content data via any one of a plurality of relay devices. A storage unit stores first priority information indicating the utilization priority of each of the plurality of relay devices when the plurality of relay devices are utilized. A reception unit receives second priority information transmitted from another transmission terminal and indicating the utilization priority of each of the relay devices when the other transmission terminal utilizes the relay devices. A selection unit selects, as a relay device to be utilized, one of the relay devices on the basis of the first and the second priority information.

Description

technical field [0001] The present invention relates to a technique of selecting a relay device that relays content data. Background technique [0002] As an example of a transmission system for transmitting and receiving content data between a plurality of transmission terminals via a relay device, there is a video conference system for holding a video conference via a communication network such as the Internet. Since it is possible to hold a conference with a plurality of people present at different places by using the video conferencing system, it is possible to reduce the cost of business travel and the time spent in the business travel. Accordingly, the demand for videoconferencing systems has increased. A video conference system uses a plurality of video conference terminals as transmission terminals. Video conferencing is realized by sending and receiving image data and sound data between video terminals. [0003] Due to the improvement of the broadband environment...
