Data stream compression

Webtime data transmission is still a problem and varying delays mostly due to congestions in routers appear as well as packet loss. In order to still use the Internet for TPTA communication makes it impera-tive to use special data compression and transmission strategies for haptic data streams. TPTA systems like the one described in [3] normally ...

WebMar 27, 2024 · Video encoding is the process of compressing and potentially changing the format of video content, sometimes even changing an analog source to a digital one. In regards to compression, the goal is so that it consumes less space. This is because it’s a lossy process that throws away information related to the video. WebVESA introduced the first Display Stream Compression (DSC) standard in 2014 and it quickly became the industry standard for data compression across the display interface. DSC was the first to offer a low latency, low complexity codec expressly designed for this purpose. DSC 1.1 has been incorporated into the VESA Embedded DisplayPort (eDP) …
