Proactive Caching technique delivers high-definition video streaming on railroad transportation systems

Test conducted on Keikyu Daishi Line in February

munications, and Fujitsu Kyushu Network Technologies Ltd. have successfully developed and verified a technique that utilizes proactive caching to deliver high-definition video streaming on railroad transportation systems.

In collaboration with Keihin Electric Express Railway Ltd. and Nippon Telegraph and Telephone East Corporation, the research group tested and verified the proactive caching system using the Keikyu Daishi Line on February 20th 2015. This proactive caching system enables users to continuously stream high-definition content during transit and despite high-volume data traffic.

The proactive caching technique used on the Keikyu Daishi Line is based on the Ministry of Internal Affairs and Communications' "Proactive Content Caching utilizing Transportation Systems" method which was developed by Waseda University Professor Takuro Sato. This new technique will contribute to the creation of new markets that result from the fusion of transportation and communication systems and strengthen communications infrastructure.
