Abstract: A method performed by a communications system, for authenticating a station, STA, to access a network is provided. The STA is capable of communicating with a light source. The method comprises: Sending (201) by a management server to a controller of the light source, network access information, Sending (202) by the light source to the STA, the received network access information, which network access information is sent to the STA via a Visual Light Communication, VLC, channel, which VLC channel is emitted from the light source and received by a light detector in the STA,and Authenticating(207)by the STA, the STA to the network by sending the received network access information to an Access Point, AP, operating in the network, wherein the STA communicates with the AP via a communication channel.

Abstract: A biststream of encoded video data captured by a camera (4) of a user device (1, 2, 3) is received and decoded into a stream of decoded video frames. A light pattern representing a VLC signal captured by the camera (4) is identified in at least one decoded video frame and decoded into a DRM identifier. Distribution of the bitstream is controlled based on a comparison of the DRM identifier and a defined DRM identifier. Hence, VCL is used to add watermarks to recorded video data and where such watermarks can be used to control distribution of copyright or digital rights protected video content.

Abstract translation: 由用户设备（1,2,3）的相机（4）捕获的编码视频数据的双串接收并被解码成解码的视频帧流。 表示由相机（4）捕获的VLC信号的光图案在至少一个解码的视频帧中被识别并被解码成DRM标识符。 基于DRM标识符和定义的DRM标识符的比较来控制比特流的分布。 因此，VCL用于向记录的视频数据添加水印，并且其中这些水印可以用于控制版权或数字版权保护的视频内容的分发。
