Hi,
your link for that channel is down (error 500) but I think all channels are same right.Just tried zee-tv-hd now.Channel does not close after 15 seconds if you play it in a player only on website you get any Login Info etc but channel is also still running in background.Just grab playlist and play it.Inside you can read 3 quality paths you can choose.
Code:
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=116000,CODECS="avc1.66.30,mp4a.40.2",RESOLUTION=176x144
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=364000,CODECS="avc1.66.30,mp4a.40.2",RESOLUTION=640x360
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=564000,CODECS="avc1.77.30,mp4a.40.2",RESOLUTION=640x360
