vz (ViZualizator) Real-Time TV dynamic graphics production, channel brending, system
Contents |
About
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).
Hardware requirements
Minimum is nVidia VGA board higher ther GeForce 5200, other manufacturer's board not supported. CPU and RAM configuation depends on task it will be used for.
For dual video input channels + animated background its require Dual Xeon configuration with nVidia QuadroFX board.
The easy task you need the lighter hardware configuration required.
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.
