BSkyB is to revamp its pricing structure, in a move which will push the cost of the firm's premium pay-TV package above £500 ($909) a year.
BSkyB's aims to attract 10 million UK subscribers by 2010
BSkyB said it hoped to attract new subscribers by reorganising its channels into six channel mixes.
The UK firm, which is part-owned by Rupert Murdoch's News Corporation, is facing growing competition from cable rivals and digital platform Freeview.
BSkyB hopes to attract 10 million subscribers in the UK by 2010.
BSkyB said the revamped channel mixes would include music, news, knowledge and children's programmes.
The broadcaster said the monthly fee for its premium Sky World package - which includes live coverage of Premiership football matches and Sky's movie channels - will increase from £41 to £42.50, bringing the annual total to £510.
The cheapest package, which includes two mixes, will cost £15 per month, while taking all six mixes will cost £21 per month, BSkyB said.
BSkyB's current £13.50 entry-level package will be phased out for new subscribers when the new pricing structure comes into effect from 1 September.
Chief executive James Murdoch is under increasing pressure to deliver new subscribers after investors reacted coolly to an ambitious growth strategy outlined last year.
BSkyB currently has almost eight million subscribers.
"These changes will enable the company to attract a growing number of profitable subscribers as Sky heads for 10 million subscribers in 2010," a spokesman for BSkyB said.
