What is "Video Conference" |
|
 Technological advances have made it possible to transmit data swiftly across the world, even huge volumes of information.
Actually, each phone call is also based on this principle, only the bulk of data is minuscule, and in spite of its being unidirectional, our ears are not sensitive enough to notice the minimal delay in the other party's response. For us, the pace is fast enough, and it sounds just like a live conversation.
However, when we wish to transmit live pictures of objects in movement (a video or live filming of what is happening in the room) we need the capacity to transmit a lot of material, and the transmission must be two-way, in order for the transmission and reception to pass through the same receptacle.
In order to complete this mission successfully, equipment was invented that can condense the numerous data, send it to its destination and then expand it again, to get the true picture that was transmitted.
The Video Conference system does exactly that.
A special camera, including a sensitive microphone, records everything that goes on in the room, sending the data to a special computer that "knows" how to "shrink" it. Then, using special ISDN communication lines, it transmits all the data to its destination. There, the process is done backwards: The condensed data is expanded, and the live pictures are presented on special screens.
It sounds simple, but only those who understand the secrets of technical data, realize the enormity of this invention. After all, how many of us thank Thomas A. Edison every day, for having invented the electric light bulb that lights up our homes? Like all great inventions, this, too, was harnessed for the benefit of mankind, and we harnessed it for the benefit of the sick people that we help.
Today, any doctor around the world, who wishes to examine a patient in Israel, doesn't request that the patient come to him. He can do it, using the sophisticated
system at Ezra Lemarpeh. The doctor can talk to the patient, see him, take different close-ups and watch the medical information that presents the patient's problem.
The doctor is there, but actually, he is here.
However, to avoid any misundestanding, a patient who must have an invasive medical treatment, would do better to stand next to the doctor... (Although even here, there have been great advances in this field, and many operations are done by robots that are activated from a distance, with the commands being transmitted using this method.) |
