vz (ViZualizator) Real-Time TV graphics production system

Overview

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 - http://www.bluefish.com, supported SD|Greed
streamalpha - http://www.stream-labs.com/, StreamAlphaPlus card tested.

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

-It's a best way to describe a features and behavior of software
+== Documentation ==
-===Sample #1 - simple graphics subtitling graphics application.===
-Find appropriate "telnet" program for operating. "putty" is nice free program.
-Step by step with screen shot explaination:
-*0. Install and start application
-*1. Start telnet program, connect to remote tcp port and load scene:
-<pre>
-[verem@pamir vz]$ telnet dev-2 8001
-Trying 10.1.5.63...
-Connected to dev-2.internal.m1stereo.tv (10.1.5.63).
-Escape character is '^]'.
-ViZualizator (vz-1.00-test-rc0) [tcpserver]
-vz in$> renderman.load(./projects/demo1.xml)
-vz out$> OK!Load
-vz in$>
-</pre>
-As result you can see scene loaded:
-{|
-|-
-| valign="top"|
-[[image:Vz_demo1_fill_s1_full.png|none|thumb|250px|[[help:contents|FILL]]]]
-| valign="top"|
-[[image:Vz_demo1_alpha_s1_full.png|none|thumb|250px|[[help:contents|KEY]]]]
-|}
-*2. Setup values of approprate fields and start "director" to show up content:
-<pre>
-vz in$> scene.tree.function.text_1.s_text=Maksym Veremeyenko
-vz out$> OK
-vz in$> scene.tree.function.text_2.s_text=ViZualizator developer
-vz out$> OK
-vz in$> scene.tree.motion.director.main.start()
-vz out$> OK
-vz in$>

-| valign="top"|
-[[image:Vz_demo1_alpha_s2_full.png|none|thumb|250px|[[help:contents|KEY]]]]

-*3. After few seconds hide the scene:
-<pre>
-vz in$> scene.tree.motion.director.main.cont()
-vz out$> OK
-vz in$> quit
-vz out$> Bye!
-Connection closed by foreign host.
-[verem@pamir vz]$

-As result you can see scene return to previous state:
-{|

-| valign="top"|

-vz out$> OK
