Are there some medical procedures that don work as well using Real-Time (Live) Telemedicine?
A. Some neurological consultations such as trying to determine the finite movement of a tremor could sometimes not be as accurate over video as compared to in person. This is due to video compression and frame rates of the live Telemedicine consultations. In order to reduce the need for extremely high network bandwidths video systems compress the image by redrawing only significant areas of movement on the screen and/or a set number of refreshed frames known as key frames. Without getting too technical, standard video is made up of 30 still picture frames per second and compression throws out a number of picture frames every second which could make a tremor you see over video not as bad as it truly is in real life due to the loss of those picture frames.
