The complex was designed and produced for the Hockey World Championship 2000 and was installed in Sport Palace "Yubileyny" (St.-Petersburg).
Application:
Indoor sports events and shows.
The complex enables to demonstare ready-made graphics and live video broadcast.
Description:
The complex consists of 3 functional parts: the alphanumeric part, the moving message display, the video display.
Video Display Advantages:
- high resolution 224 x 320 pixels, enables to get high-precision live-video
- color high-precision
- enhanced brightness correction range
- programmable gamma-correction capability
- LED clusters with enhanced viewing angle - 120° (according to the half brightness level)
At the installation moment this video display was the best in Russia according to its tech-operating characteristics.
Main game information is displayed on the alphanumeric part.
Moving message display is used for messages displaying in two modes: static mode and "moving signs" mode.
There's a capability to accompany message displaying on the "moving signs" line by various static and dynamic effects.
Alphanumeric part and moving message display are separate units that have common control system.
Features:
- live video
- computer graphics and animation
- real time sources mixing
- game timers
- score
- period
- penalties
- team names
- messages in static mode and "moving signs" mode
Parameters to Set:
- game time duration
- game time counting up/down
- horn frequency and horn duration
- LED color (alphanumeric part and moving message display)
- live video brightness and contrast
- baud rate
Control:
PC iPentium, television mini-studio, control panel.
The alphanumeric part and the video display are controlled separately.
The alphanumeric part is controlled by PC iPentium via the original interface card PCI_RG that is worked out by Nata-Info specialists. This card is connected up to the PCI computer slot and enables to control 2 video displays simultaneously.
Either the cable of category 3 UTP or two coaxial cables with wave strength are used for data transfer. Data transfer protocol satisfies the TAXI AMD firm requirements. Baud rate is 35 Mb/sec.
Active control of computer graphics, live video including real time sources mixing is realized by means of specialized equipment set.
Hardware:
- CPU - Pentium II 450MHz
- RAM - 64 Mb or above for Windows'95/98/Me, 128 Mb or above for Windows NT
- 15 Mb free disk space
- video adapter with DirectX support
Software:
