The Journal cited unnamed sources as saying Google will take the unprecedented step of stamping its own brand on the home-entertainment system, which was expected to debut this year.

Google, which announced in August it is buying US smartphone maker Motorola Mobility for $12.5 billion in cash, told AFP it would not comment on "rumor and speculation."

The California-based technology firm has openly shared a vision of its open-source Android software being used to power a wide array of devices aside from smartphones and tablets.

Google also operates an Internet music service along with video-sharing website YouTube, both of which have potential to provide digital content to home entertainment systems.
