This permits a much lighter cable and a much smaller connector on the mobile device, as a typical MHL source will be shared with USB 2.0 on a standard 5-pin Micro-USB receptacle. There are a total of five pins used in MHL rather than the 19 used in HDMI, namely: a differential pair for data, a bi-directional control channel (CBUS), power charging supply, and ground. It has several aspects in common with HDMI, such as the ability to carry uncompressed HDCP encrypted high-definition video, eight-channel surround sound, and control remote devices with Consumer Electronics Control (CEC). (To deliver an MHL signal to a non-MHL HDMI socket, one can use an adapter device that receives the signal on an MHL-enabled socket, converts it to HDMI, and transmits the HDMI signal to the non-MHL socket). Unlike DVI, which is compatible with HDMI using only passive cables and adapters, MHL requires that the HDMI socket be MHL-enabled. MHL is an adaptation of HDMI intended for mobile devices such as smartphones and tablets. The MHL Control Bus repurposes the USB On-The-Go ID (pin 4), and the HDMI Hot Plug Detect (pin 19), while the pins for power & ground match their original assignment for both. The MHL TMDS data lane (purple & green) uses the differential pair present in both USB 2.0 (Data− & Data+) and HDMI (TMDS Data0− & Data0+). Pin assignments for Micro-USB to MHL-enabled HDMI. MHL announced in 2014 that more than half a billion MHL-capable products had been shipped since the standard was created. The first mobile device to feature the MHL standard was the Samsung Galaxy S II, announced at the 2011 Mobile World Congress. May 2011 marked the first retail availability of MHL-enabled products. The MHL specification version 1.0 was released in June 2010, and the Compliance Test Specification (CTS) was released in December 2010. The working group was announced in September 2009, and the MHL Consortium founded in April 2010 by Nokia, Samsung, Silicon Image, Sony and Toshiba. The company is quoted as saying it did not ship that original technology in any volume, but used it as a way to get a working group started. 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. Silicon Image, one of the founding companies of the HDMI standard, originally demonstrated a mobile interconnect at the January 2008 Consumer Electronics Show (CES), based on its transition-minimized differential signaling (TMDS) technology. MHL was developed by a consortium of five companies: Nokia, Samsung, Silicon Image, Sony and Toshiba. MHL connects to display devices either directly through special HDMI inputs that are MHL-enabled, or indirectly through standard HDMI inputs using MHL-to-HDMI adapters. The standard was designed to share existing mobile device connectors, such as Micro-USB, and avoid the need to add additional video connectors on devices with limited space for them. You need to buy another i9100 Micro USB 5pin MHL adapter to connect it and then can use for i9300.Mobile High-Definition Link ( MHL) is an industry standard for a mobile audio/video interface that allows the connection of smartphones, tablets, and other portable consumer electronics devices to high-definition televisions (HDTVs), audio receivers, and projectors.This is Micro USB 11pin connector for new Samsung s3 i9300, cannot use for standard Micro USB MHL mobile phone like i9100 i9220.MHL Adapter allows you to connect a Micro USB (11 Pin) port to a HDMI equipped device.Allows for a Micro USB Cable (5 Pin) to be connected to the adapter to allow the phone to charge.Designed For Use With Mobile Devices Featuring MHL Technology.
