VESA Display Stream Compression for Television and Cinema Applications

75‐2: Invited Paper: Large Scale Subjective Evaluation of Display Stream Compression

“…VESA Display Stream Compression (DSC) is a lightweight video codec designed for low-impairment, low-latency compression and decompression over display links between computational devices and displays, or internal interfaces [1]. The codec is designed for a variety of display applications but in all cases the goal is to provide modest bandwidth reduction while maintaining sufficient fidelity so that a viewer cannot distinguish the compressed images or image sequences from the uncompressed source (visually lossless) [2].…”

“…In the DSC algorithm slices are independently decodable rectangular regions that can be processed independently. DSC 1.2 is reportedly less prone to horizontal slice boundary artifacts than previous versions of the codec, therefore, slice width in these trials was always at least 2 slices per line to make it more likely that horizontal slice boundaries would be visible [1]. The slice height varied by either 108 lines or 32 lines per slice to test coding quality with respect to slice height due to uneven bit budget allocation in the first line.…”

Fog Computing as an Enabler for Immersive Media: Service Scenarios and Research Opportunities

“…This problem can be solved by applying a technique called redundant view mining [42], which is able to reduce the processing time by about 36%. More recently, machine learning techniques have been used 1 We consider 162 • × 135 • fields of view (FoV), 60 pixels per degree, 96 bits per pixel, 1800 fps refresh rate, and display stream compression [39]. in the VR field, for instance, to support sophisticated view synthesis [43], [44] and super-resolution AR/VR [45], [46].…”

85‐1: Visually Lossless Compression of High Dynamic Range Images: A Large‐Scale Evaluation

“…Two lightweight algorithms have been developed recently to address this growing requirement. VESA Display Stream Compression standard (DSC) 1.2a is a released, lightweight video codec designed to provide low-impairment, low-latency compression for display applications with greater dynamic range [1]. The recently introduced VESA Display Compression-M Standard v1.0 (VDC-M) is a higher-complexity codec targeting higher rates of compression for use where higher pixel bandwidth is required (e.g.…”
