Downloading NDS DRM live Stream

Downloading NDS DRM live Stream

 

Can't download this stream because it is protected. http://live.tatasky.com.edgesuite.net/21/latest.m3u8

the link that is working nicely is of National channel of india and its stream url is::>
http://live.tatasky.com.edgesuite.net/40/latest.m3u8
it is working because it is NDS-DRM protection free.

But other streams like::>
http://live.tatasky.com.edgesuite.net/53/950.m3u8
are not running because of NDS-DRM protection or
due to EXT-X-KEY:METHOD as you can see by doing
view-source:http://live.tatasky.com.edgesuite.net/53/950.m3u8
(See more at http://goo.gl/S1T1M9)
and this key can be obtained from url>>
http://14.140.112.54:443/DRMS

Any solutions for this?

Note: Only works in india so if you are not in india then use a vpn.
