Play M3u8 with AuthSign parameter

Hi,
I have an URL which is

Code:
http://live1.karwan.tv/karwan.tv/net-tv/playlist.m3u8?wmsAuthSign=c2VydmVyX3RpbWU9MS8xNi8yMDE3IDI6Mzk6MDggUE0maGFzaF92YW​x1ZT1pdVlZYW9PVHZhVGYvdUhUSGtzajVBPT0mdmFsaWRtaW51dGVzPTIw

As you see the code includes some wmsAuthSign that is jQuery string parameter. This changes every 20th minutes and I can not play it after a while. How do I work around this? is there any php or programming thing that I can use on any free servers that can get the video and remove the parameter[/code]? or am I just dreaming?

Is there any solution to this?
