From BBC:
Microsoft has stepped up efforts to turn PCs into home entertainment hubs.
In his annual address to the Consumer Electronics Show (CES) in Las Vegas, Microsoft boss Bill Gates announced software which lets TVs play video or music stored on a desktop.
The products are part of Microsoft's world of "seamless computing", where digital content can be access from anywhere by any device.
"We are taking that hub concept and making it a reality," said Mr Gates.
Mr Gates also gave details about a line of handheld devices, called Portable Media Centers which can play video, music and show photos.
