Google will launch its TV service in Europe early next year, executive chairman Eric Schmidt said, despite teething problems that had led some observers to question how committed the company would remain to the project.

Google TV, which allows viewers to mix web and television content on a TV screen via a browser, was launched in the US in October but received mixed reviews and was swiftly blocked by three of the top US broadcast networks.

Large parts of the television industry, like the news and telecoms industries, view Google with suspicion and accuse it of stealing their advertising revenues without contributing to the costs of making programmes.

Schmidt sought to allay the fears of Britain's broadcasting elite in a speech to the Edinburgh television festival, the first time a non-TV executive had been invited to give the keynote MacTaggart lecture at Britain's premier industry event.

'Some in the US feared we aimed to compete with broadcasters or content creators. Actually our intent is the opposite,' he told an audience who quickly warmed to his friendly style and liberal compliments to the quality of British television.

'We seek to support the content industry by providing an open platform for the next generation of TV to evolve, the same way Android is an open platform for the next generation of mobile,' he said.

'We expect Google TV to launch in Europe early next year, and of course the UK will be among the top priorities.'

Google TV has gained little traction so far in the US, and its set top box provider Logitech International slashed prices to $99 in July from an initial price of $299.

Schmidt also included a warning to British television regulators, who he said were far more stringent than their US counterparts and threatened to throttle the development of British television companies in an increasingly global market.

'Stifling the Internet - whether by filtering or blocking or just plain turning the 'off' switch - appeals to policymakers the world over,' he said. 'Instead, policymakers should work with the grain of the Internet rather than against it.'

Google has long held ambitions in the television arena, hoping to extend its online advertising business, which made $28 billion for the company last year, to the big screens that still command the lion's share of global advertising budgets.

So far, Google has had little success breaking into the TV market, despite its ownership of the world's most popular online video site, YouTube.

Last week, however, Google agreed a deal to buy Motorola Mobility Holdings for $12.5 billion, handing it the world's leading set top box business which delivers content for many of the top cable TV companies in the US.
