LVP605 has 25 panel buttons and 1 knob, which are in operation mode when LVP605 starts to work. The functions of these buttons are as follows:

 

1) Input signal select

Buttons

Description

V1, V2, V3

Select a composite signal from 3 BNC ports

S-Video

Select a S-Video signal (PAL/ NTSC)

YPbPr

Select a YPbpr signal

VGA1, VGA2

Select a PC analog signal from 2 VGA ports

DVI

Select a PC digital signal

HDMI

Select a HDMI signal

EXT.

Select a signal from the extended port (for example: SDI/HD-SDI/3G-SDI)

 

To press above buttons will lead to switching of their audio signals correspondingly, which are output from AUDIO OUT.

 

When selecting an input signal, its information is displayed in the first line on the LCD screen, for example: “Input: HDMI”.  The second line displays the current state of this signal: if there is no signal available, a message “no signal” appears, in the meantime the indicator flickers and   the screen is blank; if there is a valid signal, it displays its format, such as “1080p_60Hz”.

blob.png 


Remark: if the extended input port (EXT.) is VGA/DVI/HDMI,the input signal for this port needs to be confirmed by dial switch, which means when dial switch is on “VGA”, the input signal for EXT. is VGA, and when it is on “DVI”, the input signal is DVI/HDMI.

 

2) Brightness adjustment (Brt+,Brt-) 

Button

Description

BRT -

Lower output brightness until 0 minimally.

BRT +

Increase output brightness until 64 or 100 maximally.


LVP605 supports 32-level output brightness adjustment. Adjustment range includes “0~64” and “0~100”, according to “brightness level”. The factory default of adjustment range is 0~64: 0 is the lowest value and 64 is the highest. To make sure of full grey scale of output image, the default of brightness is usually set as 64.

 

3) VGA automatic adjustment (Auto)

When the current input source of LVP605 is a valid VGA signal, to press this button will automatically adjust sampling parameters of the VGA signal, so that the output image is clear and complete.  

 

This operation is normally performed when a new VGA source is connected. Time taken for this automatic adjustment is different, depending on the state of signal source, but normally it’s less than 1 minute. Sometimes it’s necessary to perform several times until the output image is clear, complete and stable.

 

4) Information display (Info

Press this button, 24 items of the current settings and related information can be displayed. Before quitting information display, press “Info” again and the next item is displayed.

 

5) Seamless switching / Fade-in/Fade-out/Blending (C/F)

LVP605 can realize seamless switching and fade-in/fade-out between or blending of any two signals in different channels. There is a short moment of blank screen when switching signals in the same channel.

EXT


Seamless switching (Cut): the third line on the LCD screen shows “CUT”, in this mode, switching is seamless. When LVP605 starts to work, signal switching defaults to be seamless. 

Fade-in/Fade-out (Fade): the third line on the LCD screen shows “fade=1.0s”, in this mode, switching is fade-in/fade-out. Time for fade-in/fade-out can be set as 0.5S, 1S or 1.5S.

Blending: the LCD screen shows that the current signal is background, when selecting another signal from a different channel, two signals will blend. Press any signal button of these two again, this signal will quit from blending and be displayed independently. During this process, the effect is fade-in/fade-out.

 

Remark: 1. YPbPr does not take part in seamless switching or fade-in/fade-out, which means there is a short moment of blank screen when any signal is switched to YPbPr. It can’t be used for blending either.

2. During blending, it is only allowed to perform signal switching. If there is need to perform other operations, it is necessary to press “C/F” to quit blending at first.

 

6) PIP function (PIP/PBP: On/Off,M1, M2, M3, M4

The PIP/PBP function of LVP605 allows for locating another window in or beside the current image and size and location of this window can be set at random. PIP source can be the same as the current signal source or another source in a different channel. Here we call the current image and another image overlapped as “background” and “PIP” accordingly. The following is how to perform this function: 

Enter PIP mode: press On/Off, the indicator is on and LVP605 starts to enter PIP mode. Press a signal button to select a signal as PIP source and sources for background and PIP are displayed on the LCD screen:

 

Background:V1  

PAL

PIP: VGA

1280X1024_60Hz

 

Change PIP source: in PIP mode, press a signal button and this signal is selected as the source for PIP.

Change background source: quit PIP mode at first and then press a signal button, this signal is selected the source for background. Restart PIP mode to select new source for PIP.

Change PIP mode: LVP605 supports 4 customizable PIP modes. In each mode, size and location of background and PIP can be set differently. When PIP mode starts to work, press a PIP mode button (M1, M2, M3, M4) to select the mode accordingly.

 

7) Full / part display (Bypass)   

Press this button to switch between full and part display.

This function only works when the current selected signal is PC signal (VGA 1/ VGA 2/ DVI /HDMI). If other signals, they can’t be switched to part display.

 

State

Description

Full

Full display: the input image is compressed and fully displayed on the LED screen and the indicator is off.

Part

Part display: the input image is not compressed, thus only a part of it can be displayed on the LED screen and the indicator is on.          


Remark:
when the width and height of input image is lower than that of LED screen (output width and height), part display is invalid.

 

8) Freeze   

Press the button, the indicator is on and the current signal is frozen. Press the button again or switch to another signal to quit “Freeze”.

 

9) Multiple units connected in parallel (Mosaic)   

Only when the current input signal is DVI, press this button, the indicator is on and mosaic function of LVP605 starts to work. Press the button again, the indicator is off and LVP605 quits “Mosaic”.

 

Remark: in following conditions, mosaic function can’t work,

1. The input signal selected is not DVI. 

2. BYPASS is on.

3. The input resolution of DVI signal is different from output resolution of LVP605.


10)  Text overlay (Text)   

LVP605 allows for overlapping text, logo or flash on the current image: press “Text” and select a signal as source for text overlay. Text can be made by office software like PowerPoint.

As shown in the above table, for example, when switching on “Hot spare <V1V3>,if V1 signal is lost, LVP605 will switch to V3 automatically.

 

4) Test pattern       

LVP605 can generate 36 test patterns for testing of LED screen. “0” means the test pattern is switched off, while “1~36” stand for 36 test patterns.

 

Only when the current selected input signal works properly the test pattern can be output, otherwise there is no test pattern output.

 

5) Factory settings 

The following settings are factory settings, any improper settings or operation will lead to failure of LVP605. It is highly recommended to operate under the guidance of the manufacturer.

 

No.22: “Device ID”                                                 

This setting is used to number multiple units of LVP605 when they are connected in parallel. Parameter range: 1~255。

 

No.23: “ADC Calibration”                                              

Some problems such as color cast or extreme darkness may appear when analog signals are input to a processor of which white balance is not calibrated yet. LVP605 can automatically calibrate the white balance according to the input analog signals (CVBS, S-Video, YPbPr, VGA) to solve the above problem. The following is how to run the calibration: switch to a analog input signal, when the processor detect it and output it to a LED display, find the item No.22 “Device ID” and press “V1” 5 times to reach the item No.23 “ADC Calibration” and then press the knob to run the calibration.

Remark: before LVP605 leaves the factory, its white balance has been calibrated using standard signals, therefore please use this item with caution.

 

No.24: “Grayscale”                                                    

To reduce noise of low grayscale images, LED display system normally will remove the low grayscale part from input signals, but this will also bring information loss of images, especially dark images like night scenes.

 

LVP605 can amend this by adjusting the parameter in “Grayscale”, of which the adjustment range is 0—100. When some information of dark images is lost, to add the value of “Grayscale” will bring back the lost information and fully display the image on LED display.  

To make sure of full grayscale of output image, the default is normally set as 50.

 

No.25: “Brightness level”                                            

There are 2 different brightness levels: “0~64” and “0~100”. The factory default is 0~64, the lowest value in both two levels is 0, while the highest is different: “0~100” has higher brightness. Because of two different levels, even the same value may mean different brightness. Customers should select a suitable level according to specific application. If “brightness level” is changed, the newly selected level will be saved, even when “Device init.” is performed.

 

Remark: when multiple units of LVP605 are connected in parallel, their “Brightness level” should be the same, or their output brightness will be different. 

 

No.26: “Video stabilization”                                        

When CVBS/S-Video/HDMI/SDI is interlaced (for example: 1080i) and used as PIP, because of the limit of LVP605, video jitter might appear and this problem can be solved by “Video stabilization”.

 

Find item no.22 “Device ID”, press “V1” 5 times and “↑” to switch to item no.23 “Video stabilization”, rotate the knob to select “On” and press it to save the setting.

 

No.27: “EXT. module”                                               

When the extended input module is changed, this setting is used to make the new module work properly.

 

Find item no.22 “Device ID”, press “V1” 5 times and “↑” to switch to item no.24 “EXT. module”, rotate the knob to select and press it to save the setting. It is necessary to restart LVP605 then to make it work.

 

No.28: “Device init.”                                                 

Find item no.22 “Device ID”, press “V1” 5 times and “↑” to switch to item no.28 “Device init.”, rotate the knob to select “Confirm” and press it to restore LVP605 to factory settings. It is necessary to restart LVP605 then to make it work.

Mosaic Mode

 

The maximum output resolution of LVP605 is 2304×1152 or 2560×816 and it takes 2 sending cards to drive a LED screen with such resolution and that’s why LVP605 has 2 sending card slots; If the resolution of LED screen is above the maximum output resolution of LVP605, the screen could be “divided” into several parts and each part can be driven by one LVP605, therefore multiple units of LVP605 are connected in parallel could drive the full screen.

 

Using frame synchronization, LVP605 overcomes problems like misalignment or delay in ultra-large image mosaic and therefore it could realize real-time, clear and fluent display effects.

 

LVP605 supports multiple unit mode, which is specially used for ultra-large LED screen. For example, if the output resolution of a LVP605 is set as 1920 X 1080, then 2 units of LVP605 in parallel can drive a LED screen with resolution of 3840×1080.

 

The following is an example of 4 units of LVP605 which are used for 2 X 2 mosaic and details about how to perform it.

 

A LED screen with resolution of 3456×1920 can be divided into 4 smaller screens with resolution of 1728×960 and each part can be controlled by one LVP605, so 4 units of LVP605 in parallel can allow the big screen (3456 X 1920) to display a full image.

#2(1728×960)

 

 

#3(1728×960)

 

 

#4(1728×960)

 

 

The following is the system topology:

blob.png

 

As shown in the above picture, all input signals are connected to LVP605#0 as the master control and output from 2 DVI ports to #1 and #2, and then looped out to #3 and #4 accordingly. The output image will be cropped and scaled by #1, #2, #3 and #4, and then finally is displayed as a full image on 4 LED screens.

 

It is required to set output parameters of each LVP605 to run multiple unit mode:

Chapter 7 ViewRGB LVP605 Series Control Software

LVP605 control software is used to control LVP605 by software. With this software, we can realize:

● Seamless switching or fade-in/fade-out of input signals.

● 4 customizable PIP/PBP display modes and text overlay.

● Switching on/off bypass, freeze and mosaic

● Setting parameters of LVP605.

● Timing switching of input signals.

● Fast mosaic.

 

4-1  Control method

LVP605 can receive control command from the software to switch input signals, change output brightness and etc. LVP605 is controlled by the software via RS232 serial port of PC.


Users can use the software to manually control LVP605 via RS232 or create a timer to automatically control LVP605. 

 

Using this method, first connect the communication port (COM) of PC to RS232 port of LVP605 and then run the program: LVP605 Control Software.exe.

 

4-2  Software Interface

1)  User interface

Double click to run LVP605 Control Software.exe, user interface will appear as follows:

In this area, buttons and indicators correspond to those on the front panel of LVP605.

When devices are connected successfully, the software will read the current selected input signal of LVP605 and indicates it in a blue spot. If the blue spot is on all the time, it means the input signal works properly; if it flickers, it means the signal is invalid. 

Signal switching can be done by clicking signal buttons directly.

Information about the extended input can be checked in this area.

 

3. Info (Information bar)

blob.png 

If operation fails, the reason will be displayed in the bar.

 

4.Timer (Timer settings)

◆ Week Plan

◆ Month Plan

 

Users can select a plan desired.

Day Plan items define hour, minute and second; 

Week Plan items define day, hour, minute and second in a week; 

Month Plan items define date, hour, minute, and second in a month; 

Once Plan items define year, date, hour, minutes and second; 

Cycle plan and once plan can work together.

 

Items of each plan can be added, modified or deleted. For example, the picture below shows how to add plan items to a day plan.

In addition, when setting parameters, the blue background means a new parameter is being input or not saved yet, while the gray backgorund means it is saved already:

 

blob.png 

 

a) Input/output settings and mosaic settings

Output parameters should be set according to the resolution of LED screen. Mosaic mode and input parameters are only used for multiple unit mode. Options are provided to set whether the processor adopts synchronous or non-synchronous mosaic mode. Input parameters are used to set the location and size of the images to be captured from input image based on the actual size of the screen.

 

Remark: input image parameters shall not be configured unless the following conditions are met: 

a. The selected input signal of LVP605 is DVI. 

b. The resolution of DVI input signal should be the same as output resolution of LVP605. 

c. All units of LVP605 are in Mosaic mode (the indicator of Mosaic is on).

blob.png 

 

10. Fast MS (multiple unit mode settings)

 

Multiple units of LVP605 connected in parallel can be used to drive ultra large LED screens. Users can complete input/output parameter configuration of LVP605 through fast mosaic.

In this area, users only need to select a mosaic mode (the layout of LED) and enter the actual pixels of LED driven by each LVP605. The program will automatically calculate the mosaic parameters and save them.

Enter “Fast Mosaic”: after entering the user interface of LVP605, clickblob.png, the interface of fast mosaic will appear:

blob.png 

Remark: following conditions must be met for mosaic settings:


a) Settings of brightness, saturation, grayscale and sharpness of each LVP605 should be the same.

b) The output resolution of each LVP605 should be the same; the output resolution should be the same as DVI input resolution. 

c) The current selected input source of all units of LVP605 should be DVI and “Mosaic” function is enabled (the indicator of Mosaic is on).

 

Operating steps of Fast Mosaic: 

Before performing fast mosaic, make sure that LED screen and all units of LVP605 are working properly, and that each part of the LED screen is able to display a full picture independently. Use the serial port to connect all units of LVP605 or just one of them.

 

a) Use software to connect LVP605 

Select the device ID (same as item no. 21 “Device ID” in user settings) of the first unit, click “Connect”, it will be automatically connected, the software will then read and display its current parameters (e.g.: output resolution).

 

blob.png.

 

b) Select mosaic mode

Select the current mosaic mode in “Specification” field to decide the layout of LED screen. Users can also manually set the layout. For a LED screen of 3648x2016 pixels, it should use 2x2 mosaic mode.

 

c) Enter actual parameters of each LED 

After selecting proper mosaic mode, the field “Effects show” will display the actual layout of each LED in models, enter the width and height of each LED in turn as shown in the picture below: 

blob.png

a) Settings of the first unit of LVP605

Click a LED number in the field “Effects show” (we set the first LED asblob.png) and “Auto calculate”, the software will automatically calculate parameters of the current processor based on the parameters entered in “Effects show”. Select the Mosaic mode desired, and “Sync Mosaic” for the LED, the software will pop up the message “Configuration is successful”. Click “Set” button respectively in input and output field, the software will automatically save the parameters that it worked out in current processor.

 

Caution: both input and output parameters of LVP605 must be even, but the results of auto calculation may be odd, if so, it is necessary to set an adjusted value to correct the parameters to be even, and then you can click “Set” to save it.

blob.png 

 

b) Parameter configuration of other processors
