The Video Electronics Standards Association (VESA ) today formally introduced the VESA Display Compression-M (VDC-M) standard, a new display interface compression standard designed for embedded mobile display applications, including smart phones and other hand-held devices. Developed in collaboration with the MIPI Alliance, VDC-M provides a higher level of compression ratio (up to 5:1) at the same visually lossless quality level as VESA’s Display Stream Compression (DSC) standard (which offers up to 3:1 compression), with the trade-off of higher circuit complexity. VDC-M is the third compression standard in VESA’s family of compression codecs, which include DSC 1.1 (introduced in 2014) and DSC 1.2 (introduced in 2017).
“VESA was a pioneer in the area of low-latency data compression specifically targeting the display interface,” according to Bill Lempesis, executive director of VESA. “The initial application for VESA’s effort in this area was the Embedded DisplayPort Standard (eDP) and MIPI DSI, both which currently use DSC 1.1, with the specific intent to increase battery life and reduce form factor. The success of this spearheaded our effort on DSC 1.2 for external displays, primarily focusing on increasing display resolution. Working again with MIPI through their liaison with VESA, we returned our focus on mobile displays with VDC-M, developing a display compression standard more optimized for smaller mobile devices such as smart phones.”
