The UK government says music and film producers will have to bear of the cost of clamping down on illegal file sharers on the internet.
Rights holders will be the main beneficiaries of the government's plan to tackle online piracy and should therefore pay 75% of the cost, said Treasury minister Stephen Timms.

The remaining 25% of the campaign, expected to cost around £500m over 10 years, is to be funded by internet service providers (ISPs), according to the Financial Times.
Timms called on companies that sell content online to create legal alternatives to piracy. Progress has been much too slow, he said.
The music industry, which has urged government action after global sales fell 12% in the past year, had been pushing for the costs to be split evenly between ISPs and copyright holders.
The BPI, which represents the UK recorded music industry, said 75% is not a "fair or proportionate allocation" for rights holders.
The world music market has declined 30% since 2004, according to the latest figures from the International Federation of the Phonographic Industry.
The organisation claims piracy is a huge barrier to market growth and has called on ISPs to disconnect persistent offenders.
Under the terms of the Digital Economy Bill under debate in the House of Lords, broadband subscribers spotted by rights holders sharing content illegally will be sent letters by their ISPs and persistent offenders could face temporary suspension.
