IMAGE BLACK and WHITE
If the image is black and white using the Y/C (S-VHS) input then please check the INPUT GROUP
menu if INPUT GROUP -> INPUT MODE -> COMPOSITE or S-VHS is selected. Change to S-VHS.
Default is COMPOSITE for input 2. Default for Input 1 is S-VHS.
1.2 Quick Reference
Video Inputs
Composite and S-VHS
The inputs 1-3 can be used for composite and Y/C-signals. It is not possible to use both signals at
one time at one input. The default operation of the unit is BNC-Composite.
INPUT MODE
COMPOSITE
For Y/C(S-VHS)-operation it is necessary to change the input mode in INPUT GROUP -> INPUT
MODE -> Press the SELECT-button and change with one of the GROUP-buttons to S-VHS. Press
STORE to save the setting for next power cycle.
INPUT MODE
S-VHS
RGBS and YUV
The inputs 4 + 5 accept RGBS, RGsB and YUV signals.
The sync signal can be inputted at the V-sync input of a VGA -> 5 BNC cable. If the source has no
separate sync output it is possible to use the composite output as sync source. For SCART operation
you will need an adapter as described in the pinout section page 10. The MGVC 1280 can detect
sync on green and sync on Y. No V-sync connection is required in that case.
3 Input formats are selectable

HDTV-INPUT
Input 6 of MGVC 1280 may be configured as a HDTV input in INPUT MODE menu while
the input is active. You may select 480p, 575p, 720p and 1080i in YPrPb or RGB color format. No
external converters are necessary for direct connections to HDTV sources or progressive DVD-
players. For 480p you may select all combinations of output resolution and frame rates, for 720p the
upconversion is limited to SXGA. 1080i signals are converted to XGA or SXGA.

Output Synchronization signals
The MGVC 1280 offers separate H and V-synchronization, composite-sync or RGB with Sync on
Green. Composite-sync can be selected in the menu OUTPUT GROUP –> SYNC OUTPUT ->
Composite (on V) . Be aware that the composite sync is only available at the V-socket and not at the
H-socket. If the unit runs in SEPERATE SYNC mode the output level of the sync signals is TTL 5 V
positive or negative H and V-Sync. Composite sync can be adjusted either positive or negative. Some
older projectors may require negative composite sync. The MGVC 1280 also offers Sync on Green
which is very useful for HDTV displays.

Time Base Corrector
The integrated Time Base Corrector avoids unsynchronized distorted images of VHS tape recorders
or any other unstable video source. It is a true one field TBC and will solve many synchronization
problems occurring with digital video projectors and especially the new LC-or TFT-Displays, which
require a very stable sync signal for proper operation.

3. Picture adjustments INPUT GROUP Inputs 1-5
3.1. Brightness, Contrast, Saturation, HUE
The adjustments for Brightness, Contrast, Saturation have similar impact as with monitors or TV-
sets. There is no real optimum setting. Perfect image balance is a matter of attached projector or
display and personal preferences. HUE is only available with NTSC-signals.
BRIGHTNESS
+ 6,2 %
3.2 Horizontal and Vertical Sharpness, Details
Horizontal or Vertical Sharpness is crossrelated to the DETAILS-setting. SHARPNESS defines the
degree of edge enhancement, DETAILS the type of enhancement. DETAILS may be changed from
COARSE, MEDIUM to FINE. The vertical sharpness is a function of the comb filter which is only
active when composite inputs are used. When using Y/C or RGB/YUV inputs the VERTICAL
SHARPNESS adjustment has no impact on the image.
The best result using inputs 1-3 is achievable by increasing the detail resolution with DETAILS
setting to FINE and HORIZOTNAL SHARPNESS to STEP 1.
Input 4 + 5 may deliver good results even with higher values of HORIZONTAL SHARPNESS
up to Step 5. The degree of edge enhancement is a matter of personal preference and quality of the
input source material.
HORIZ. SHARPNESS
STEP 1
3.3 Comb-Filter (only Input 1-3)
The comb filter is needed to remove cross color artifacts of the PAL,SECAM or NTSC encoding
process. It can be deactivated for demonstration purposes. An activated Comb filter never has a
negative impact so it should be ON all the time. The function is only available in the composite input
mode. The used type of comb filter meets broadcast standards and delivers outstanding
performance.
3.4 Input Mode
This setting activates the Y/C (S-VHS) input mode on inputs 1-3.
If input 4 or 5 is active the function provides toggling between RGBS, RGsB and YUV.
The MGVC 1280 addditionally offers adjustments of active Pixel per line, Phase and the manual
selection of VESA standard in case the automatic detection is not working properly.
3.5 Standard Select
Not all video standards can be detected automatically. If the image is black and white a manual
selection of input standard may be required, e.g. SECAM sources have to be selected and stored.
The necessity for a manual selection is usually indicated by a black and white image together with
heavy distortion of the displayed image. Simply step through the standards until the display shows
proper color images.
3.6 Color Phase
Color Phase adjusts the delay between LUMA and CHROMA signals. It works only for
Y/C and composite. Usually no adjustments are necessary but a colored halo effect around sharp
edges may be an indication for a delay and a necessary compensation.
3.7 NR DEMO and Noise Reduction
The MGVC 1280 offers a very effective digital noise filter. It removes noise of low quality signals like
VHS tapes or analog reception of broadcast signals.
In the highest mode STEP 5 the noise filter also works as a stabilizer giving great results for video
signals without any motion. Typical sources are dia scanners or visualizers.
- 8 -
3.8 Horiz. Shift, Horiz. Offset and Vertical Shift
This function enables horizontal or vertical shifting of the image. If the image contains undesired
lines like closed caption it is possible to move this in the blanking area. Distortion of the picture
during adjustments can occur.
3.9 Horiz. Zoom and Vertical Zoom
The MGVC 1280 offers a certain percentage of zoom both in vertical and horizontal direction.
Together with the shift function it is a powerful tool to zoom in the active picture area for
magnification.
The higher the zoom factor the lower the video image quality.
3.10 Input Size and Shift
The Horizontal Size and Vertical Size adjustments allow the increase of active pixels.
Digital projectors or displays sometimes do show black bars at the borders of their panel area.These
unused panel area may then be filled increasing the active size of the image.
Horizontal Shift and Vertical Shift allow the positioning of the active area on the physical panel
device. Do not forget to STORE the settings after making adjustments.
Do not use the Size and Shift functions with CRT projectors because the projector itself is offering
these adjustments without affecting the image sharpness.

4. Seamless Switching or Dissolving with the MGVC 1280
IMPORTANT !!!
The output resolution of MGVC 1280 must be adjusted first to the graphic resolution applied
on input 8. If this is not performed the dissolve function will not work.
As no downscaling is supported the selected output resolution must equal or exceed the
graphic input resolution applied at input 6 or 7.
After applying a new graphic source to inputs 6 or 7 it is necessary to STORE the new recognized
input resolution. Without storing, seamless switching is not perfect.
The MGVC 1280 supports synchronous switching or dissolving between video inputs (1-7) and the
source applied on input 8.
Dissolving between inputs 1-7 is performed over black in a way that the active image is faded to
black and the new selected source is being faded in from black.
Possible Configurations:
Format PAL 50 Hz PAL 75 Hz PAL 100 Hz NTSC 60 Hz
800 x 600 X X X X
1024 x 768 X X X X
1280 x 1024 X X NO X
Most computer graphic cards do not allow the selection of 50 Hz as a refresh rate, although this
would be the optimum setting for PAL. In this case we recommend the selection of 75 Hz which is a
VESA standard and should be available with any standard VGA graphics adaptor.
You may find a very useful software package POWER STRIP from ENTECH
www.entechtaiwan.com
that allows elaborated manipulation of the graphic card timings.
4.1 Adjustments for Inputs 6 and 7 for the MGVC 1280
The MGVC 1280 offers the scaling of inputs 6 and 7 to the desired output format and frame rate.
The selected ouput resolution in the OUTPUT GROUP menu must have the same value of the
input signal applied at input 8 or any of the available options in the free run mode.
As no downscaling is supported the selected output resolution must equal or exceed the input
resolution applied at input 6 or 7.
The MGVC 1280 is also compatible with american HDTV signals which are usually in a progressive
YPrPb-format in 480p, 575p, 720p or 1080i on its input 6. The MGVC 1280 will convert the YPrPb
or RGBHV signals in a RGBHV format which may be outputted in higher resolution and different
frame rate. The MGVC 1280 is also compatible for future RGB signals in a progressive format.
INPUT 6 also handles RGsB with Sync on Green. Inputs 6 will also accept HDTV 1080i, 720p and
480p in RGBHV format for conversion into XGA and SXGA .
- 10 -
4.3 Connecting a graphic source to the MGVC 1280
1. For seamless operation you must first connect the graphic source or genlock signal
(RGBHV format) at input 8.
2. Then adjust the output resolution of the MGVC 1280 while any of INPUT 1-5 is active to
the resolution of the applied genlock signal at input 8. Possible settinges are SVGA, XGA
and SXGA at 50,60 or 75/100Hz.
3. Additional graphic sources may be connected at input 6 or 7. The highest possible
resolution for seamless switching or dissolving is 1024 x 768@75 Hz.
4. First select the desired input 6 or 7. Then go to the menu INPUT GROUP and select the
appropriate input resolution format of the offered VESA Standards in the sub-menu
STANDARD SELECT or leave it an automatic detection (AUTO mode). For older PCs it
may be required to select the VESA standard manually. If you have an image with
irregularities(banding) going fromt top to the bottom of the image you must manually adjust
the pixelclock of the MGVC 1280. Go to the menu CLOCKS PER LINE and try to adjust
the image with UP/DOWN buttons. Further adjustment are possible in the PHASE sub-
menu. It may be required to approximate the perfect adjustment toggling between PHASE
and CLOCKS PER LINE. PHASE determines the position where the sample of the input
signal is located. It is a trial and error procedure and best performed with a special test
signal where repetitively one pixel is black and the adjacent white.
PHASE
00.00 °
5. After applying a new source to inputs 6-8 it is necessary to STORE the new recognized
output resolution. Without storing, seamless switching is not possible.
ATTENTION !!!!!
The MGVC 1280 cannot downconvert any input signals. The image quality of downconverted
computer images is unacceptable whereas upconversion is almost lossless. That requires that the
output resolution has to be selected higher or equal to the graphic input source at input 6 or 7.
- 11 -
4.4 Example for Seamless Switching between Genlock input 8 and Video
Assuming you want to switch/dissolve between a video input (1-5) and a 1024 x 768/60 Hz
computer image, following steps are requried.
1. First select an output resolution according to the resolution of your computer device
which is connected at Input 8, in this expample we assumed 1024 x 768/60 Hz.
2. Connect the computer source to input 8 and activate input 1 pressing the button
labelled 1.
3. Adjust the output resolution to XGA with 1024 x 768/60 Hz. Additonal computers may be
connected at INPUT 6 or 7.
4. Go to the System group menu and activate MIXER MODE to ON.
MIXER MODE
ON
Additional computers must be of same or lower resolution than the genlock source connected
at Input 8. In this case the maximum supported resolution is 1024 x 768/60 Hz. For a new computer
source at Input 6 or 7 with a resolution of 800x 600, perform following steps:
1. If the input is in AUTO mode and you have an image, no interaction of the operator is
necessary.
2. If not, you have to select the 800 x 600/60 Hz in the STANDARD SELECT menu of input 6.
3. If the image is without any distortion press the STOREbutton.
4. If not, you will have to optimize the pixel clock and phase adjustments described earlier.
5. After storing you may now dissolve or cut your video and grapic sources without any glitch
or interruption of synchronisation. If you want to dissolve or cut between different inputs the
unit will cut or fade over black. Real dissolve is supported between any Input 1-7 and Input
8.
4.5 Adjustment for Dissolve and mixing of images
You may adjust the transition time in the SYSTEM GROUP menu:
FADE TIME
0.5 sec
If the time is set to 0 the unit will perform an instant cut.
Characteristic of the dissolve. Selection of linear or hyperbolic is possible.
MIXER Transition
Linear
4.6 Input resolutions for Seamless Switching
Not all input resolutions can be combined with one of the 3 output resolutions and frame
rates.Especially the 100 Hz refresh rate is not recommended for seamless switching operation of
the unit. For 50/60 Hz refresh all combination are possible though the output resolution cannot not
be smaller than the applied input res.
5. Adjustments for OUTPUT GROUP
5.1 Output Standard
Adjustment is only possible if Input 1-5 is active !!!
Pressing the SELECT-button initiates the blinking cursor. Select one of the 3 ouput resolutions with
the GROUP button. Please refer to the table of scan frequencies. If the projector or display device is
not locking to PAL 50 Hz operation it may be necessary to increase the frame rate setting to 75 Hz.
- 12 -
6. Audio adjustments and inputs
6.1 Audio routing
The audio inputs 1-4 are logically connected to the video inputs 1-3. If one of input 5,6,7 or 8 is
selected audio input 4 is active at the output. It is possible to store parameters like volume, bass,etc.
for each of the inputs 1-8 independetly though.
6.2 Volume, Bass, Treble, Balance, Gain
Each stereo input offers separate adjustments for VOLUME, BASS, TREBLE, GAIN and
BALANCE. The adjustments are stored separately for each channel and are recalled any time the
audio/video input is changed. The gain adjustment is needed to reduce the input level if distortion
occurs even with low volume setting.
7. Adjustments in the SYSTEM GROUP MENU
7.1 LCD Illumination, the display brightness may be adjusted in 3 levels
7.2 LEDs ON/OFF, activates/deactivates the INPUT LEDs.
7.3 IR REMOTE, activates/deactivates the IR Remote operation.
7.4 Coprocessor
The possible adjustments are GAME-FILM-VIDEO-AUDIO and have impact on the image
processing. Usually AUTO should be ok, but some source material is funny encoded and if
combing and jagged edges can be seen a manual selection of one of the available manual settings
may improve the result. Which mode gives best results is best determined on an experimental basis
and there are no recommendations but to try it.
7.5 Subtitle Processing
The subtitling which is available on DVDs can cause a problem in the AUTO film mode detection
of the processor. The activation can improve this.
7.6 SW-Download SELECT
see chapter 11, Firmware UPDATE
7.7 Communication
The Vigatec scalers may be adjusted to 9600, 19200 and 38400 baud for the serial interface.
Default setting is 19200 baud.
7.8. Initialisation, INIT
INIT activates Factory Defaults for all parameters. The buttons SELECT and INIT have to be
pressed simultaneously for at least 3 seconds.
7.9 RESET
RESET activates Factory Defaults for the active inputs. The buttons SELECT and RESET have to
be pressed simultaneously for at least 3 seconds.

7.10 Loading DEFAULT setting and resetting user memory
To clear the internal EEPROM and totally reset the unit to factory defaults it is necessary to press
the STORE button while powering on the unit. This is necessary after firmware upgrades and
may help if you detect a non standard behaviour of the unit.
7.11 Recovery start from internal ROM
The Vigatec scalers have a factory programmed EPROM and a user writable FLASH memory
that stores the new version if upgrades have been performed. In case something went wrong with
the Firmware upgrade you may start the unit from the factory EPROM. Press SELECT button
while powering ON.
