VVC/H.266 Multi-layer Coding Technologies
for Advanced Broadcasting Services
NHK has developed a real-time Versatile Video Coding (VVC*) decoder that supports multi-layer coding for efficient compression of multiple videos. This multi-layer coding is suitable for video distribution on various home and personal devices, such as TVs, tablets, smartphones, and so on.
* ISO/IEC 23090-3| Rec. ITU-T H.266
The technologies can provide video services for personalized viewing styles within a limited transmission bandwidth.
While transmitting a video separately for each viewing style is inefficient, broadcasting services for diverse viewing environments can be efficiently transmitted using multi-layer coding technology.
