videocon d2h carries 48 sd chs in one mpeg4 dvb se 54 mhz tp bcoz each 54 mhz tp can carry 50 percent more chs than what a 36 mhz tp can do, also as videocon d2h uses mpeg4 tech for sd chs(plus hd chs) so it can add double the chs that what tata sky can do in a mpeg2 sd ch tp. so in total videocon d2h can carry 2 and a half times sd chs(as it is using mpeg 4 tech for sd channels and has 54 mhz transponders) on a single transponder than what tata sky can do and 50 percent more hd chs on a single hd tp (as its a54 mhz mpeg4 tp) than what tata sky can do(as its only a 36 mhz mpeg4 tp only for hd chs)
