A multi‐screen environment provides a new opportunity for digital signage applications, where various irregularly shaped screens are employed as an effective means for advertisements and information. A formation method applicable to numerous irregularly shaped screens is proposed to provide a new perspective on digital signage applications. The crucial part of the proposed method comes from the geometric sensing of each screen and the formation of a virtual screen where geometrically aligned content extraction and encoding are employed for content transmission to each screen. In addition, a software‐based synchronization method for the proposed system is proposed to address the frame‐level synchronization between screens. The experimental results of the proposed method show an improved performance of the frame‐level synchronization, where the inconsistency between frames is not identified.
