A total of three sets of new video coding technologies that are being formulated by related international standards setting organizations are likely to be rolled out in 2020 that will be conducive for addressing the two shortcomings related to unsatisfied compression rates and unfair licensing mechanism of current HEVC (high efficiency video coding) technology for coding and decoding of ultra-high 8K video images, according to Digitimes Research.
The new video coding standards include VVC (Versatile Video Coding) initiated by JVET and MPEG-5 EVC (Essential Video Coding) and MPEG-5 LCVEC (Low Complexity Enhancement Video Coding) prepared by MPEG (Moving Picture Experts Group).
EVC has a compression efficiency rate that is 50% higher than that of HEVE, and it allows developers to use related tools free of charge to develop EVC solutions or EVC encoders under a friendly patent authorization mechanism.
Meanwhile, LCEVC utilizes not traditional encoding methods to reduce the complexity of existing encoding techniques and improve image quality. This technology enables service providers carry out software updates on existing encoding and decoding hardware architecture.
Digitimes Research believes that VVC is likely to replace HEVC for 8K encoding and decoding and will be incorporated into the next generation of 8K TV video processing solutions. Since EVC and LCEVC can solve part of the licensing issue and the compatibility of related equipment, video service providers are likely to upgrade their related services optimized these two technologies.
