Group Finalizes MHL Spec For Portable-To-TV Link

Sunnyvale, Calif. – The

MHL Consortium

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

The standard was developed by Nokia, Samsung Electronics, Silicon
Image, Sony and Toshiba.
