TightVNC

In computing, TightVNC is a cross-platform free and open-source remote desktop software application. Constantin Kaplinsky developed TightVNC,[3] using and extending the RFB protocol of Virtual Network Computing (VNC) to allow end-users to control another computer's screen remotely.

Encodings

TightVNC uses so-called "tight encoding" of areas, which improves performance over low bandwidth connection. It is effectively a combination of the JPEG and zlib compression mechanisms.[4][5] It is possible to watch videos and play DirectX games through TightVNC over a broadband connection, albeit at a low frame rate.

TightVNC includes many other common features of VNC derivatives, such as file transfer capability.

Compatibility

TightVNC is cross-compatible with other client and server implementations of VNC; however, tight encoding is not supported by most other implementations, so it is necessary to use TightVNC at both ends to gain the full advantage of its enhancements.[6]

Among notable enhancements are file transfers, support for Windows DFMirage mirror driver to detect screen updates (saves CPU time and increases the performance of TightVNC), ability to zoom the picture and automatic SSH tunneling on Unix.

Since the 2.0 beta, TightVNC supports auto scaling, which resizes the viewer window to the remote users desktop size, regardless of the resolution of the host computer.

Derived software

RemoteVNC

RemoteVNC is a fork of the TightVNC project and adds automatic traversal of NAT and firewalls using Jingle.

TightVNC Portable Edition

The developers have also produced a portable version of the software,[7] available as both U3 and standalone downloads.

TurboVNC

TurboVNC is based on the TightVNC 1.3.x, xf4vnc, X.org, and TigerVNC code bases and includes numerous performance enhancements and features targeted at 3D and video workloads.[8][9]

TigerVNC

TigerVNC is VNC server and client software, started as a fork of TightVNC in 2009, after three years of inactivity in TightVNC trunk. It also takes some code from TurboVNC.[10]

gollark: No.
gollark: For private use only.
gollark: Anyway, I'm trying to make a simple web frontend for Youtube-DL as part of the osmarks horrible API of suffering.
gollark: Fascinating.
