IPTV Software for iMac

Hello there,

I'm searching a lot with out luck.

I watch TV via Wi-Fi in my home on Safari via my local network. Is there a way/software to control what I watch ?

For example I'd like Time Shift, Record, Forward, Rewind etc..My device is Broadway from Hauppauge and it has not Time Shift.

Any help will be fine.

Thanks in advance.
