No. A video grabber card (VGC) is required only if you wish to transmit the video of live surgery. It is basically needed to interface your Laparoscopic / Endoscopic Camera with the computer/laptop.
If you just need to view the surgery transmission, then the grabber card is not required.
The sound from the speaker interferes with the microphone and echoes your voice, thus disturb others. Hence using a separate headphone and microphone is preferred. A studio grade microphone provides the best quality sound.
The latest Laparoscopy / Endoscopy systems have High Definition (HD) digital cameras. However, you need to have high bandwidth Internet connection to transmit a HD quality video. The S-VIDEO and COMP VIDEO outputs of the CCU provide good and acceptable quality videos which can be viewed even at lower bandwidths. The various output options available in a Medical Grade Laparoscopy / Endoscopy Camera Control unit (CCU) are shown here:
Transmitting analog video using a Video Grabber Card
Use the Video Grabber Card (VGC) to connect your computer to the CCU. Below figure shows a typical VGC. A VGC may consist:
A CCU can be interfaced with the computer either by using the COMP VIDEO (Composite Video) or S-VIDEO outs.

Creating/Editing/Deleting Surgery Schedule
I have a transmitter access on LapGuru. What is the procedure to transmit the video of my live surgery?
- Connecting the CCU to the computer/laptop
For details on the connections, please refer Q. How to connect Camera unit to the computer?
- Flash Media Live Encoder (FMLE) settings
Once the connections between the CCU and the computer are done, you need to start the Adobe Flash Media Live Encoder (latest version of the same can be downloaded from the Internet) to set the input device and configure the video type. This is the one time process which is carried out as mentioned below:
Start the FMLE.
FMLE detects the input device (Video Grabber Card) that you have connected to your computer. You can see the VGC details in the FMLE window.
The Device drop down list in the Video section of the Encoding Options tab lists all the video devices
From the Device drop down list, select the video device that you have connected to your computer as shown below.

I had created a new surgery schedule. However I am unable to find the same on the Live Surgeries tab now.
- The surgery schedules are removed from the Live Surgeries tab once the date for which it was created is already passed. Hence if your surgery schedule was created for a past date, you will not be able to view the same on Live Surgeries tab now, and you will have to create a new schedule by clicking on button.
- The surgery schedules are removed from the Live Surgeries tab if the same does not start within 10 hours from its start time.
I have created a surgery transmission for a particular date; however my plan is changed now. Can I make the changes in scheduled date & time for my surgery?
I wish to broadcast my surgery on LapGuru. Can I provide restricted access for watching the same only to people I wish to invite to watch my surgery?
Yes. You may have a Private transmission through LapGuru, and only people having its unique transmission code will be able to watch the same. To create a private surgery schedule:
- Click on button, after logging to your LapGuru account.
- Select Access Level as Private using toggle button
- On the click of Save. A unique transmission code will be generated and displayed by LapGuru. You can see the same on Live Surgeries tab too such as
- Send this code to the people you wish to invite to watch your transmission. Only such viewers will be able to connect to watch your private transmission.
I would like to broadcast a conference having surgery transmissions from hospitals at multiple locations. Can the viewers watch all surgeries together?
- Yes, the same can be done using LapGuru Conference feature. For creating such conference schedule:
- Go to Conferences tab after Login to your LapGuru account.
- Click on button.

Audio/ Video Related
Please ensure that your microphone is properly connected to the computer. The Flash player automatically detects the microphone that is connected to your computer.
- In the Flash player window, Right-click and select Settings.
Click Flash player should show the microphone that is connected to your computer. If the sound is ON, then it will show bars as per the intensity of the sound in the setting below.
- Click Select Allow and Remember.
Using the inbuilt microphone of the laptop can create an echo and can cause a lot of disturbance to the other users. Do not use the inbuilt mic of your laptop instead use a separate headphone and microphone.
I am showing the surgery transmission to a group of people in an auditorium. However, when I speak, there are multiple voices created and that creates a lot of disturbance.
When the speaker is used to transmit audio (like in an auditorium) the user/ trainer should use a unidirectional microphone, otherwise, the audio coming from the speaker will be fed back to the mic and may create an echo.
Now, you need not click Allow every time you start the flash player
I had started the video transmission of my live surgery, however the video got stuck in between/ I was watching the video transmission, however the video got stuck in between.
If the video gets stuck in between, restart the flash player window again as mentioned below:
- Click on Exit transmissionon the flash player window.
- Close the flash player window where you were seeing the video.
- Go back to the Live Surgeries tab, click once again on or and click on Play
I am using LapGuru for training purpose. The quality of the surgery video on my computer is good, but the quality on the projector screen is blurred.
Quality of the video on the projector depends on the quality of the transmitted video. A SD video transmission will look blurred or pixilated on a projected screen, however, if the video is transmitted in HD, the pixilation would be minimal or not there at all.
Viewing Live/Recorded Surgeries
- Registered surgeon on LapGuru portal can Watch Transmission of his choice by clicking on
The select conference access shows the list of current LapGuru transmitters.
Click on Adobe Flash Player window opens
Ensure that you have installed the Adobe Flash Player (version 11 or later) on your computer/laptop.
- Click Play. Adobe Flash Player Settings window pops up.
- Click Allow. The Flash Player plays the video of the surgery that is being transmitted by the other surgeon.
The video quality depends on the source of the video, the bandwidth available at the transmitter end and the type of the transmission (SD, SD+, HD are the types in increasing order of quality). The quality of the video also depends on the speed of the viewer’s Internet connection (bandwidth). Typically, SD will require around 500 kbps of bandwidth, SD+ will require around 2Mbps of bandwidth and HD will require around 4 Mbps of bandwidth.
If the video is getting transmitted at bandwidth higher than that of your available bandwidth, you may see a jerky or choppy video. Ideally, the viewer needs to have same download speed as that of the uploading speed of the transmitter. To check the speed of your Internet connection, please visit http://www.speedtest.net and click on Begin Test.
I clicked on Exit transmission button while I was watching a surgery transmission. Can I re-connect to watch the same surgery?
After clicking on Play on the Adobe Flash Player window, I got an error message- Shockwave Flash has crashed and can see a blank window.
- Open Google Chrome browser window and type about: plugins or chrome://plugins/ in the address bar and press Enter.
- You can see the list of all plug-ins installed in Chrome.
- Look down the list of plug-ins for the Flash entry. If the entry looks like Flash (2 Files) there is a very good chance the source of your Flash-related crashes is a conflict between the two.
- In the upper right hand corner of the browser window there is a small button labeled [+] Details. Click on that to expand the entries for all the plug-ins. Return to the entry for Flash.You should see something like the screenshot above: two entries for Flash, one for the internal Chrome installation (highlighted in red here) and one for the host OS’s installation (seen below the highlighted entry).
You need to click on the Disable link for Chrome’s internal installation of Flash- similar to the one marked in red (make sure you disable the one located in Chrome’s AppData folder and not the separate stand-alone Flash installation). Once you do so the entry for the internal installation should look like so:
- Now close all the Google Chrome browser windows, and restart Chrome and go to www.lapguru.com to watch the surgery videos.
Using LapGuru’s Key features
While I was watching surgery transmission I had drawn some arrow marks and circles on the screen. However later on I clicked on Erase Shape button. Will this clear the marks on the other attendee's screens as well?
