Transmission control apparatus and transmission control method

摘要

A transmission control apparatus includes: a communication unit communicating with each of communication apparatuses, which are included in a communication system in which communication is executed via one relay apparatus, via the relay apparatus; a determination unit determining, as a transmission apparatus transmitting content data indicating a content to be transmitted, the apparatus with higher transmission quality between the apparatus and the relay apparatus in the communication system based on quality information of each communication apparatus, which is received by the communication unit and includes information regarding the transmission quality between the relay apparatus and the communication apparatus; and a transmission control unit allowing the transmission apparatus determined by the determination unit to concurrently transmit the content data indicating the content to the respective apparatuses of the communication system excluding the transmission apparatus.

1. A communication system, comprising:
a plurality of content reproduction devices, each including a communication unit; a relay apparatus configured to communicate with the communication unit of each of the plurality of content reproduction devices; and a transmission control unit configured to:
receive path quality information for each of the plurality of content reproduction devices from the respective communication units thereof, the path quality information of each respective content reproduction device identifying a quality of a communication path between the communication unit of the respective content reproduction device and the relay apparatus;compare the path quality information of each of the content reproduction devices and select one of the plurality of content reproduction devices to be a content transmitting device based on the comparison; andtransmit to the selected content transmitting device a content-transmission command that identifies a given item of content data that is to be reproduced by the plurality of content reproduction devices and commands the selected content transmitting device to transmit the given item of content data, wherein each of the plurality of content reproduction devices is configured such that, if the respective content reproduction device receives the content-transmission command, the respective content reproduction device begins concurrent transmission of the given item of content data to each of the other ones of the plurality of content reproduction devices via the relay.
