Summary:The new versatile video coding (VVC) standard is designed as a multi-purpose coding method to enhance both compression performance and functionality. Multilayer coding is one of significant features of this functionality. Mainstream single layer profiles in the traditional standards, such as AVC/H.264 and HEVC/H.265, are not designed to support multilayer coding functionality. The functionality is implemented in the extensional multilayer profiles. In contrast, VVC is designed to get this multilayer coding function as a basic function of new video coding. VVC implemented both Main 10 and Multilayer Main 10 profiles as primary profiles based on common architecture. The Multilayer Main 10 profile efficiently encodes multiple videos with varied resolutions, frame rates, and qualities. This study proposes a novel multilayer functionality using the Multilayer Main 10 profile, termed content layering, and introduces a pioneering sign-language video service system for broadcasting, which is envisaged as a next-generation broadcasting service.
