1 Data Transfer Technology to Enable Communication between Displays and Smart Devices 倉木健介 中潟昌平 田中竜太 阿南泰三 あらまし Abstract Recently, the chance to see videos in various places has increased due to the speedup of networks and spread of digital signage. However, most of the videos are noninteractively broadcast at viewers, and currently viewers often input keywords related to the videos in a search site after they see the videos when they want to find out some information related to the videos. So that viewers can easily obtain information related to videos, Fujitsu Laboratories Ltd. has developed new data transfer technology that enables communication between videos and smart devices by embedding communication information into the videos invisibly and extracting it using the camera application of smart devices. Viewers are able to acquire information related to videos easily just by filming them. In this paper, we introduce an outline and the usage scenarios of this data transfer technology via video data. 504 FUJITSU. 64, 5, p , 2013
