Title:
DATA COMPRESSION DEVICE AND DATA COMPRESSION APPROVAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/208568
Kind Code:
A1
Abstract:
In the present invention, a data compression device (for example, a server device which relays streaming of content) determines whether congestion has occurred in a communication network which communicates with a data compression approval device (for example, a terminal device). When the data compression approval device receives, from the data compression device, a congestion occurrence signal indicating that congestion has occurred in the communication network and a data compression inquiry signal which inquires whether data compression is possible, the data compression approval device generates a data compression response signal and sends the same to the data compression device. If a determination is made that congestion has occurred in the communication network, and when a data compression response signal indicating that data compression is possible is received from the data compression approval device, the data compression device compresses the content data and sends the compressed content data to the data compression approval device. Due to this configuration, even if it was not possible at the time of user contract execution to confirm with a user that content data may be compressed, the data compression device compresses content data in accordance with congestion in the communication network, sends the compressed content data to the data compression approval device and suppresses congestion occurring in the communication network.
