Random news from the Archive VESA VDC-M compression standard
17.05.2018
VESA has introduced Display Compression-M (VDC-M) - a new compression standard for interfaces for connecting built-in displays of mobile devices, including smartphones.
Developed in collaboration with MIPI, it provides higher compression (up to 5:1) than the VESA Display Stream Compression (DSC) standard, which provides compression up to 3:1. At the same time, "no visible loss of quality" is maintained. The payoff for increasing the compression ratio is the complication of the scheme. VDC-M is the third in a family that also includes DSC 1.1 introduced in 2014 and DSC 1.2 published in 2017.
The need for a new codec is caused by an increase in the resolution of displays. The association hopes that VDC-M will find the same wide application as its predecessors. MIPI is already planning to include VDC-M in a future specification for mobile displays.
