Can Microsoft's Xbox conquer China?

Microsoft's Xbox will officially go on sale in China for the first time today.

It is the first gaming console to go on sale in China in 14 years after the government relaxed a ban on the products.

For years, the three big console makers - Microsoft, Sony and Nintendo - wanted access to China's multi-billion dollar market.

But as the BBC's Beijing correspondent Martin Patience reports, they'll now face tough competition.
