Sunnyvale, Calif. - The
finalized its Mobile High-Definition Link 1.0 specification, intended to standardize a high-definition video and multichannel-audio connection between mobile devices and TVs.
The five-pin interface would deliver 5-volt 500mA power to a connected cellphone, portable media player or tablet-style portable device to charge their batteries. The cable connection would also carry HD video up to 1080p/60Hz from the portable device to the TV or display, using High-bandwidth Digital Content Protection (HDCP) to protect audio and video content from unauthorized copying. The connector will also transport up to 7.1 channels of LPCM and compressed audio and let users access their portable device's content via the display's remote.
"One of the key advantages of the MHL specification is that it enables manufacturers to utilize widely established connectors available in today's mobile and CE products," the consortium said. "Utilizing existing connectors saves valuable space in devices by keeping form factors small, allows for cost-effective implementation and enables consumers to get more functionality and features from a single connector," said MHL president Barry McAuliffe.
The standard was developed by Nokia, Samsung Electronics, Silicon Image, Sony and Toshiba.
