On 1 October 2010, Sky began the process of downloading open-source software to Sky+ HD receivers.

An HD receiver is a digital box that is designed to receive HD broadcasts.

You might already have an integrated TV with an HD receiver built in.

Some are even HD-ready, able to display high-definition content with the connection of an external HD receiver.

It has been reported that 27 million HD receivers had been sold in Japan as of October 2007.

Digital radio requires the purchase of HD receivers, which remain expensive, although prices are falling rapidly.

In addition to being available via an HD receiver, the station is also available at the Penguins website.

Current HD receivers support the 480i, 480p, 720p and 1080i resolutions.

Many direct-view sets are now equipped with a built-in HD receiver.

Other Linux-based HD receivers became available in the meantime.
