Hello,
I already have this done. Easy installer, streaming, channels, vod, transcoding, client portal with management, everything you need, just a full iptv solution.
One time payment, lifetime updates !
I can show you demo.
The panel is not in JSP / oracle , but it's running onlinux Ubuntu, you can have unlimited resources / servers / channels / clients / etc .
It integrates with ANY device on this world, even gets channels from sattelite if you have the right hardware.
If you are interessed, please let me know.
Thanks.
