DSC (Display Stream Compression will) image streaming Compression set by VESA association, support the VESA DSC a version 1.2, the biggest can support 4.5:1 Compression ratio (@ 12 BPC).By DSC function, the user can be in the same bandwidth transmission under the condition of a greater amount of information, under the condition of not unlock the function of DSC, DP 1.2 a specification to support maximum resolution to 8 k @ 30 hz, 4:4:4, 8 Bits image output, under the open DSC function can be as high as 8 k @ 60 hz, 4:4:4, 12 Bits of resolution and color depth.
DSC (Display Stream Compression will) adopts software Compression method, provide the user through the Chroma 2238 belongs to VPG Master software to DSC parameters setting, image Compression, real-time preview.
Built-in software industry commonly used 37 DSC chart file, the user can also load itself external test image file (support Bitmap image, JPEN image, Tiff image, Portable Pix Map image), DSC data compression, storage of 100 at most.
Through the VPG Master software users can choose the BPP (Bits Per Pixel) and the BPC (Bits Per Component) each 8/10/12 Bits, offers a variety of different compression ratio to the user to set the application.
The user can Set the test image file number of horizontal and vertical cutting (Picture Parameter Set) :
- Level (Horizontal) : 1/2/4/6/8/10/12/16/20/24
- Vertical (Vertical) : 1/2/4/8
In DSC coding process, Slice technology can reduce the distortion after compression, a variety of cutting combinations with different test conditions and application by the user.
VPG Master software supports RGB/YCbCr simple_422 native_422 / native_420 etc. The application of five kinds of image output mode.
Have the ability to Read Sink DSC (Read DSC "Capabilities), the user can be set to Read module Slot and DP Port, press the Read button after VPG Master software will automatically load the parameter values of measured objects (Sink) DSC (orange box below the dotted line), the analyte and to facilitate users to understand (Sink) ability of DSC.
Users can input string (at most) input 31 characters to display content, custom printing on the image file of the font, size, color, position coordinates, and preview the custom and test the content of the string position, can be directly downloaded to Chroma in 2238, and to facilitate users to identify DSC open and compression parameters set by the state.
