DSC800M2 Multiformat 10 bit digital video switcher
Recommended application:
The device is assembled in modulo style which makes it possible to solve practically any tasks in studio. The mixer can be installed with mixed equipment both digital and analog thus removing problems related mixing non-sync analog and digital video signals; also there is no need for additional converters since it makes it possible to work directly with the non-sync analog and video signals, i.e. PAL, SECAM, S-video, YUV, DV. The device is small and it is suitable for mobile television studios thus saving both free room and money costs for television monitoring systems providing possibility to monitor all inputs (up to 16) on one TFT monitor simultaneously. This controlling monitor is connected via DVI connector delivering the clear picture which shows the entire necessary information improving work conditions for service personnel. The regional studios with limited budget can also benefit because the mixer provides cost reduction in the case of video tape recorders, materials and service personnel. The cumbersome tape recorders can be replaced with CompactFlash Card Reader and the 12 hot buttons system for playing prestored video clips. It is possible to use computer for longer video clips.
Base characteristics and the functional possibilities of the mixer.
1.The module based construction with possibility to increase and diversify the number of inputs. The following inputs and outputs are possible:
Base Module. This is a 'must have' module in the system.
2DV Inputs Module. Can be used to input signals from DV cameras or DV tape recorders.
CompactFlash Card Reader is supplied as option with 2DV Inputs Module.
4SDI Inputs Module.
2SDI Outputs Module.
6CVBS Inputs/2Y Inputs/ 3YC Inputs Module can be adjusted by user.
SECAM Outputs Module.
2.Audio mixing board in-sync with the video mixer.
3.10bit video processing.
4.TBC for each input.
5.Mutliscreen function. A TFT monitor can be connected to monitor all the inputs and outputs simultaneously.
6.Audio Level bars.
7.An optional CompactFlash Card Reader for 2DV Inputs Module
8.An optional DVPlayer Software running on Windows XP 32bit PC. It can be used together with 2DV Inputs Module to playback the DV video clip.
9.The maximum number of inputs is 16. All the functions can be controlled via PC.
10.Overlaying of two logos with A-channel using 2 hot buttons. Up to 14 prestored logos in the nonvolatile memory. The logographics can be created by almost any graphic editing software.
11.Two prestored still pictures.
12.Digital clock.
13.Temperature sensor.
14.Separate connector for external GenLock.
15.Builin Title Generator used for introduction and editing of text information overlaying output video in form of fixed writings, horizontal or vertical scrolling. The text can be stored in nonvolatile memory for later use.
16.Logos and Still Pictures are uploaded from PC via RS232 port.
17.The device can be controlled by PC via RS232 enabling automatic broadcasting mode.
18.The list of signals generated internally by the device:
2 Still Pictures.
2 Logos.
Digital clock.
Temperature (option).
Hor and Ver title scrolling
test lines generator
Tally signals
Color Bars
Test Audio Signal 1000 Hz
12 video clips played from optional CompactFlash Card Reader.
