It is also the first time for DVB to absorb Chinese video standards.

DVB testing results show that AVS3 can save 40.09% bit rate compared to HEVC(H.265) for the same picture quality, which is praised as one of the most efficient video coding technologies in the world.

After 20 years of development, the AVS standard has been formed9 international IEEE standards, 13 national standards, 3 industry standards, 18 group standardsIt has become the core technology standard for HD, 4K and 8K ultra HD radio and television channels.
