Interface Utilizes Widely Established Mobile and CE Connectors

SUNNYVALE, Calif. — MHL, LLC the entity responsible for administering the MHL Consortium, today announced the availability of the MHL™ (Mobile High-Definition Link) specification version 1.0 and Adopter Agreement. The MHL standard defines a new mobile interface to directly connect mobile phones and other portable consumer electronics devices to high-definition televisions and displays. 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 increasing availability of storage and media capabilities on smartphones, tablets, and other mobile electronics is contributing to the consumption of video on the go,” said Michael Palma, senior research analyst for Consumer Semiconductors of market research firm IDC. “The MHL specification should enhance the ability to link these portable devices to HDTVs opening up opportunities for manufacturers and service providers to deliver new applications and add more value for consumers.”

The MHL 1.0 specification delivers the following functionality:

  • Video: Up to 1080p/60 picture quality can be displayed from portable devices to TVs and displays.
  • Audio: Up to 192 kHz of audio transmission is supported, delivering up to 7.1 channel Linear Pulse Code Modulation (LPCM) surround sound and compressed audio.
  • Power: Five volts and 500 mA are provided from an A/V device to continuously power the portable device and charge its batteries.

Products implementing the MHL 1.0 specification have the following benefits:

  • Connect: With a simple 5-pin interface, mobile devices can output high-quality video and digital audio over a single cable while receiving power from TVs and displays and multi-purposing existing connectors in the market.
  • Control: Consumers can display digital media from portable devices to A/V devices and access content with a remote through command and control technology.
  • Protect: High-value video and audio content is safe from unauthorized interception and copying with High-bandwidth Digital Content Protection (HDCP).

“Our 1.0 specification release marks another MHL milestone and brings us one step closer in achieving our goal of becoming the standard of choice for wired mobile connectivity,” said Barry McAuliffe, president of MHL, LLC. “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.”
