# Remote Graphics Software

HP ZCentral Remote Boost, formerly known as HP Remote Graphics Software or HP RGS, is a client-server remote desktop software developed by HP Inc. Launched in 2003. HP RGS enables remote access to workstations (or virtual workstations) from many different devices, including other workstations and thin-clients. Screen sharing between multiple users, remote USB, as well as Windows and Linux are supported. HP markets RGS for "Real-Time Collaboration," "Workstation-Class Mobility," and "Remote Workers"
In 2014, HP released RGS 7.0 which brought remote workstation use cases to tablet devices. The remote desktop tool has less latency and packet losscompared to Citrix HDX 3D or Teradici's PCoiP.
In 2020, HP updated and rebranded RGS as part of the HP ZCentral Solution. ZCentral Remote Boost was awarded an Engineering Emmy Award in 2020.
HP RGS processing and hardware-accelerated graphics are done on the workstation and only compressed bitmap images (the screen) are sent to the client device.
There are two components to the software, the sender (for the workstation or server) and the receiver (for the client device). The software supports OpenGL and Microsoft DirectX. The software is sold stand alone for servers, virtual machines and non-HP Workstations. HP started including RGS with all of its desktop Z brand workstations starting with version 5.4.7 in 2011. RGS can be downloaded from HP and run on HP Z Workstations and ZBook mobile workstations for free.
An early version of the HP RGS video compression codec, is derived from a patented system developed by HP Labs and used in the NASA Mars rover program.
