It enables the streaming of graphical desktop environments across different operating systems by implementing the RFB protocol to exchange pixel data and input events. The software provides secure remote access through password authentication and the use of cryptographic certificates to verify remote server identities. It facilitates remote system management by capturing a local display on a server and forwarding it to a viewer application for remote control. The system includes capabilities for display performance optimization, such as adaptive pixel-format encoding and color depth adjustments based on network conditions. User interface features include full-screen display modes, viewport scaling, and the management of remote input events. ## Tags ### Networking & Communication - [RFB Protocol Implementations](https://awesome-repositories.com/f/networking-communication/rfb-protocol-implementations.md) — Implements the RFB binary protocol to synchronize remote frame buffers and exchange input events. - [Remote Desktop Clients](https://awesome-repositories.com/f/networking-communication/remote-access-control/remote-desktop-clients.md) — Provides a viewer application that renders a remote graphical interface and sends user input back to the server. - [Remote Desktop Protocols](https://awesome-repositories.com/f/networking-communication/remote-access-control/remote-desktop-protocols.md) — Implements the RFB communication standard for exchanging pixel data and input events between a server and a viewer. - [Remote UI Access](https://awesome-repositories.com/f/networking-communication/remote-access/remote-ui-access.md) — Enables accessing and controlling a graphical user interface on a remote computer from a local device over a network. - [Remote Desktop Streaming](https://awesome-repositories.com/f/networking-communication/remote-desktop-streaming.md) — Streams a graphical desktop environment from one operating system to another for remote work or troubleshooting. - [Remote Input Relays](https://awesome-repositories.com/f/networking-communication/remote-input-relays.md) — Implements a system for transmitting keyboard and mouse input events from a local viewer to the remote host over the network.
