VESA DSC Encoder

The VESA DSC and VDC-M IP cores deliver visually lossless video compression for mobile, AR/VR and automotive display applications.

Contact Provider Request Datasheet

Overview

The VESA DSC and VDC-M IP cores deliver visually lossless video compression for mobile, AR/VR and automotive display applications.

The VESA DSC IP cores can compress any image to 8 bits per pixel (bpp), which results in a 3X compression ratio for a 24 bpp image or a 3.75X compression ratio for a 30 bpp image. The VDC-M cores use more sophisticated video encoding tools to achieve even higher compression factors for applications that require even more compression. VDC-M can reduce a 30 bpp uncompressed image to 6 bpp, and in some use cases, it can be visually lossless at a 6X compression ratio.

The VESA DSC and VDC-M IP cores can be combined with the MIPI DSI-2 Controller cores, and your choice of C/D-PHY, to form a complete display solution.
