ELGIN, Ill., Feb. 13, 2018 /PRNewswire/ -- Teledyne LeCroy, the worldwide leader in protocol test solutions, today announced a test solution for analysis of Display Stream Compression (DSC) on DisplayPort High Bit Rate 3 (HBR3) video streams. This the first analysis solution for DSC aimed at UHD and higher pixel rate development teams.
DSC is primarily used in portable, battery powered systems with embedded displays, such as smartphones and tablets, to both save system power and reduce cost by decreasing the number of interconnect wires. But DSC is also used to boost external display resolution. Until now, makers of DSC-capable sources of DisplayPort HBR3 video streams were unable verify key functions of their DSC implementations. This new DSC analysis feature from Teledyne LeCroy will enable developers to view the DisplayPort DSC related protocol elements such as the picture parameter set, end of chunk packets and compression flag settings in the VBID to ensure that these elements are occurring in the video stream and that they are occurring in the proper sequence. The DSC analysis feature also captures and decompresses the video frames enabling developers to examine them for compression artifacts. There are no limitations in this solution on the number of DSC slices or pixel rate in the DSC analysis feature. And the Forward Error Correction (FEC) transport mechanism, which ensures reliable, error free video transport, can also be verified. In addition to the DisplayPort main link analysis, the aux channel DPCD transactions related to DSC and FEC configuration can be viewed through the Auxiliary Channel Analyzer (ACA) utility.
"As the variety of consumer electronic products incorporating the DisplayPort digital interface to drive 4K and higher video resolutions continues to increase, it is essential for the supply chain to have the test tools necessary to verify the rich set of enhancements that the latest versions of the DisplayPort interface now offers, such as Display Stream Compression (DSC) and High Bit Rate 3 (HBR3). We welcome and encourage the addition of new tools to the DisplayPort ecosystem that verify and support these advanced features," said Bill Lempesis, executive director of the Video Electronics Standards Association (VESA).
"The DisplayPort specifications have evolved rapidly to incorporate a wide range of features. We are excited to be at the forefront, offering integrators and developers of DisplayPort transmitter silicon a comprehensive solution for higher speed video streams," said Kevin Prusso, VP of Sales and Marketing for Teledyne LeCroy's Protocol Solutions Group, which includes the quantum data line of video test products.
The DSC analysis feature is a licensed option being offered in the quantumdata 980B or 980R platform when equipped with the 980 DisplayPort 1.4 Video Generator / Protocol Analyzer module and licensed for DisplayPort capture and analysis.
