HDR Vivid

Bringing out vibrant colors

HDR Vivid is released by the UWA,and intelligently optimizes HDR schemes on a frame-by-frame basis. With dynamic metadata and tone mapping, this technology dynamically adjusts display effects based on the actual brightness and color information to deliver consistent color vibrancy and detail. HDR Vivid tweaks images to display colors and textures closer to reality, with precise contrast and distinct bright and dark regions.

AVS3

8K/4K UHD codec with leading performance

AVS3, published in October 2021, is the next-generation UHD audio and video encoding standard designated by China's NRTA, DVB, and IEEE. AVS3 is the latest member of the family of video encoding standards developed by China's AVS Workgroup. It is capable of encoding video with approximately 40% bitrate savings for the same subjective quality compared to HEVC. This places AVS3 among the world's most efficient video encoding technologies.
