Medical conference between Buenos Aires and Istanbul with Analog Way presentation mixers

2 3

2MGNet provided the audiovisual system for a medical event that took place at the same time in Buenos Aires, Argentina and Istanbul, Turkey. In Istanbul, several physicians attended a conference on minimally invasive brain surgery. The conference focused on operations that were performed in Buenos Aires.

2MGNet had to set up a full audiovisual system to transmit via satellite the audio and video signals generated from various medical devices and monitors, through three independent SAT-Links. Amongst the video signals there were 4 x DVI, 1 x VGA and 3 x SDI signals. The objective was to obtain these video signals generated in Buenos Aires from their various sources, process them and route them onto the SAT-COM vehicle for outgoing transmission in Istanbul.
According to Nicholas Sterin, Project Manager at 2MGNet: “Providing clear and accurate imaging was key for this event, since all content transmitted was projected on a wide screen, so as to explain and teach medical procedures to a large number of people.”

At the “Sagrada Familia” health clinic of Buenos Aires, operations took place in two separated operating rooms (OR). There, 2MGNet did a specific set-up for each room as outgoing signals were different from one room to another. OR#1 had four outgoing DVI signals from a split frame monitor and one SDI signal from camera covering all operations. OR#2 had one 3D DVI signal and two SDI signals.
To handle these different signals, 2MGNet used one Di-VentiX II (Ref. DVX8044), Analog Way’s Multi-Layer Hi-Resolution Mixer Seamless Switcher for OR#1. Two Pulses (Ref. PLS300), Analog Way’s Dual Scaler Mixer Seamless Switcher, were used for OR#2.

In regards to OR#1, the request consisted in receiving and processing all the different signals, and arranging them into a two frame display - main video output - composed of two layers which divided the screen down the center. Moreover, an additional PIP layer would be positioned on the top right corner of the screen. Nicholas Sterin explains: “The idea was to switch amongst the four incoming signals from the split frame monitors - 4 frames depicting several brain and vital signs images - so as to show two signals at a time. This, while always displaying live coverage from the camera (SD-TV / BNC Input).” 

The Di-VentiX II was used in Mixer mode. Connected to the device there were four DVI sources plus one SDI source, signal was output in SDI (1080i). 2MGNet used several features of the Di-VentiX II for the event including layer position and cropping: “Apart from the configuration challenges which were easily solved by the Di-VentiX II capabilities, one particular advantage that the equipment provides is the layer cropping”, says Sterin. When first contacted by the coordinators on the “Turkey” side of the event, 2MGNet was provided with one of the 4 frames depicted on the medical monitor from which there would be 4 x DVI signals received. Originated from a determined medical device, each frame was showing a high definition 3D image of every blood vessel in the brain, veins and arteries. Each of the four frames had a grey/white thick stripe with numerous data and parameters that was coming down along its side, and that needed to be removed. “As we were asked to remove said stripes to send the video only, we used the Di-VentiX II’s layer adjust menu to zoom in the input and obtain the source with no stripe as required”, details Sterin.

The two Pulses were used for OR#2, in order to achieve the same configuration display as OR#1. The only difference was in terms of signals as there were one 3D DVI, one analog video and one SD-TV from the live coverage for OR#2. Nicholas Sterin explains the configuration: “In order to put all signals together as requested, we decided to merge one background layer and PIP layer into one of the Pulse’s main video output. Then, we sent the main video output into the second Pulse’s input.” Through this process, 2MGNet achieved the same configuration as in OR#1. “By mixing two video signals in the first Pulse and sending it to the other, we were able to insert the 3rd video signal as a PIP layer on the top right corner of the screen.”
