Implementing hardcore protected type of streaming.
For example, streams of the type Apple QuickTime video:
rtsp://***.mov incl. security key/token
or
rtsp://***.mp4 inc. security key/token
are virtually impossible to pirate (incl. VLC media player chap
).
Segmented streaming (see NBA, National Basketball Assoc.) is an alternative to Quicktime but more complicated/expensive.
