Revision as of 21:08, 30 June 2010
The MHL™ (Mobile High-Definition Link) Consortium was formed to develop a new mobile audio/video interface standard for directly connecting mobile phones and other portable consumer electronics (CE) devices to high-definition televisions (HDTVs) and displays. The MHL standard features a single-cable with a low pin-count interface able to support up to 1080p high-definition (HD) video and digital audio while simultaneously providing power to the mobile device.
Features
- MHL provides HD audio/video with a low pin count, enabling high definition audio and video using the mobile device’s existing multipurpose connector.
- MHL supports high-quality digital HD video up to 1080p.
- MHL supports audio up to 7.1 channel LPCM, at sample rates up to 192K.
- MHL simultaneously provides power to the mobile device from the connected TV. This allows the TV side to keep the content flowing from the mobile device while not discharging the battery. The power flow allows the TV to re-charge the mobile device as well. An MHL Sink can provide 500mA of power at 5 volts.
- MHL supports High-bandwidth Digital Content Protection.
- MHL includes a control bus which allows, among other functions, a TV to control a mobile device with the TV's remote control.
By transporting the digital content in digital form, the full impact of the picture (whether still images or video) can be seen on HDTVs.
History
Silicon Image originally demonstrated a mobile interconnect, based on its TMDS technology, at the January 2008 Consumer Electronics Show.. This interface was termed "Mobile High Definition Link" at the time of the demonstration, and is a direct precursor of the implementation announced by the MHL Consortium.
The company is quoted as saying it did not ship that original technology in any volume, but used it as a way to get the working group started.
A Working Group was announced in September 2009 to develop a specification based on MHL Technology..
The MHL Consortium was announced by the companies of the Mobile High-definition Working Group on April 14, 2010. Nokia, Samsung, Silicon Image, Sony and Toshiba had been working on a specification since the Working Group announcement in September, 2009..
MHL, LLC is the Agent for overseeing the licensing and promotion of the MHL Specification.
Introduction
An abridged version of the specification was made available for download on April 14, 2010 from http://www.mhlconsortium.org. A nonrefundable fee of $100 is charged.
The MHL 1.0 Specification was announced on June 30, 2010.
Details on adopter agreement are also available on the MHL Consortium web site.
