saw that term, and would like to know the technology required to qualify as one.
for example i know about the transceivers used to turn a tunable/descrambled
cabletv channel into a data stream, or ota tuner/encrypter into a data stream.
is restreaming like being a p2p seed or a tor relay? you just need isp upload?
A restreamer generally buys a service from a provider, provides their own hardware that receives the streams and then sells those streams as their own service. Problems require escalation with the provider.
