提出了一种基于可见光通信(VLC)的隐式信息服务系统.将隐式信息嵌入载体图像或视频中,既保证原有图像、视频的正常显示,又能使隐式信息被成像器件获取并由相应算法解码恢复.对众多广告信息进行人眼视觉不可见的推送,可以有效地避免广告轰炸,实现针对目标人群的定向宣传.本系统易于移植于手机、平板电脑等手持设备操作平台.实验验证了系统的可行性,对影响系统性能的主要因素进行了评估.

An invisible information casting system based on visible light communication (VLC) is proposed.Invisible information is embedded in normal displayed images which can be captured by imaging devices and recovered by corresponding decoding algorithms under the premise of displaying original images and videos normally.Transmitting advertisement information in the invisible way can avoid the harassment by mass media and realize directional advertisement to the target customers.The system is easy to be transplanted to many handheld devices like cell phones and pads.Finally,the system feasibility is verified and the main factors which affect the system performance are evaluated through experiments.
