vz (ViZualizator) is software complex for generation realtime TV-graphics. Fine and easy solution for TV studio graphics, channel branding and TV-Interective solutions.

Its based on OpenGL rendering engine that perform rendering target picture in video adapter's framebuffer and block code that transfer framebuffer from videocard to video output adapter's framebuffer.

Rendering objects list is supplied from external file (in XML format). It's tree - based description of graphics primitives layout and operation about parameters changing.

Managing of vz behavior performed by external program that communicate with main rendering module using TCP protocol. Main program provides telnet-like shell where external commands send throw using predefined syntax. Command could be used for loading "scene" file (primitives layout), modification parameters of graphic primitives or for starting/stopping timeline's complex (called director).

Supported Outputs

Video output provided by professional TV video output board. For now there are 2 supported:

bluefish

Most tested video output driver. For operating require 5.4.18 drivers version. Support almost all hardware supported features. Successfully tested with SD|Greed. Manufacturer site is www.Bluefish444.com.

streamalpha

StreamAlphaPlus card tested long time ago. Not sure about current version. Manufacturer site is www.stream-labs.com

nullvideo

Fake output video module. Used for emulating CPU load, texture transfer and can be used as skeleton for writing new output modules

Output driver could be written for almost all adapters with open SDK.
