I. INTRODUCTION
Video information hiding is one of the crucial techniques to provide diverse video services, such as video authentication and augmentation [1], [2], [3]. It refers to hiding different types of featured information into video streams for either security authentication, e.g., watermarking, or metadata in video augmentation, e.g., depth-map embedding, motion information embedding, and extended-color information. Thus, the development of advanced video information hiding techniques has high value for various new multimedia applications.
