METHOD AND SYSTEM FOR ASYNCHRONOUS LAMP IDENTIFICATION |
摘要 |
The invention relates to embedding data into a luminance output generated by an illumination system comprising a light source and a controller. The controller is configured to embed data by modulating a drive signal applied to the light source with an information signal comprising a shifted base code and a synchronization code. The synchronization code serves to provide synchronization for the receiver, while the shifted base code serves to carry the embedded data. A cyclic phase shift that is applied to a base code to generate the shifted base code corresponds to particular data, such as, for example, light source identification,that needs to be embedded into the luminance output of the illumination system. In this manner, data may be embedded into the luminance output generated by a light source without requiring synchronization of this light source with other light sources. |
