Telemedicine and satelite
Telemedicine requires real-time video and audio interchange with a medicalprofessional. Its becomming more common, especially these days. My experience with on attempt at a telemedicine session sugge...
Bandwidth increases wouldn't change latency, as latency is a result of the distance between the satellite and your site.
OK. So what else explains the breaking up of transmission?
Latency + congestion
Congestion = traffic on the beam, which is the geographic area the satellite signal covers.
Too many people using the system at the same time in the same geographical area overloads the system's capacity.

Telemedicine is not that much different from streaming, and streaming is not the same as downloading a single file. You're not getting a whole file when you stream. You're getting packets of smaller video/audio segments that require regular handshaking to ensure each packet is complete and received in the correct order. Each handshake requires several pings back and forth which may be delayed by different times. Whether the handshake was received by the server in time for the next packet and/or how not receiving it at all is interpreted by the server determines if the stream is halted in a 'buffered' state or not. Making matters worse, telemedicine and other forms of video conversations (e.g., Skype, Facetime) are more complex than this because they're trying to synchronize in both directions, not just one.
In my haste I meant to add that if the server deems the packet wasn't recieved, when in fact it just got the handshake late, it may attempt to resend the packet anyway, resulting in using twice the data.
