Top consumer electronics companies have revealed they are teaming up to effectively create a mobile, or mini, version of the HDMI port for portable devices and phones.

Nokia, Samsung, Sony and Toshiba have all announced they are working with Silicon Image to form the Mobile High-Definition Interface Working Group.

The group will go on to create an industry standard for an audio/video interface to connect mobile phones or other portable devices directly to high-definition televisions and displays.

The new standard will be based on Silicon Image's "Mobile High-Definition Link" tech and will be offered as an industry standard open to all companies. The aim is for the standard to be easy and cost effective for manufacturers and simple and reliable for consumers.

Silicon Image says "a single-cable with a low pin count interface will be able to support up to 1080p high-definition digital video and HD audio in addition to delivering power to a portable device".

You can be sure it will be a while before anything is finalised, but we will keep you posted.
