Overview

MHL is an adaptation of
HDMI
High-Definition Multimedia Interface (HDMI) is a proprietary digital interface used to transmit high-quality video and audio signals between devices. It is commonly used to connect devices such as televisions, computer monitors, projectors, gam ...
intended for mobile devices such as smartphones and tablets.
Unlike
DVI, which is compatible with HDMI using only passive cables and adapters, MHL requires that the HDMI socket be MHL-enabled. (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). It has several aspects in common with HDMI, such as the ability to carry

(CEC).
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. 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

receptacle.
(Although MHL ports can be dedicated to MHL alone, the standard is designed to permit port sharing with the most commonly used ports.) The USB port switches from USB to MHL when it recognizes an MHL-qualified sink (e.g., a TV) detected on the control wire. A typical MHL sink will be shared with HDMI on a standard 19-pin HDMI receptacle.
Because the same five-pin Micro-USB port is also typically used for charging the device, the sink is required to provide power to maintain the state of charge (or even recharge) while it is being used (although this is dependent on the power available being sufficient e.g., MHL 2 & 3 provide a minimum of 4.5 W / 900 mA, while superMHL can provide up to 40 W). The use of the power line in this way differs from HDMI, which expects the source to provide 55 mA for the purpose of reading the

of a display.
Because of to the low pin count of MHL versus HDMI, the functions that are carried on separate dedicated pins on HDMI, namely: the
Display Data Channel (DDC) (pins 15 & 16) and CEC (pin 13) are instead carried on the bi-directional control bus (CBUS). The CBUS both emulates the function of the DDC bus and also carries an MHL sideband channel (MSC), which emulates the CEC bus function, and allows a TV remote to control the media player on a phone with its Remote Control Protocol (RCP).
Bandwidth
MHL uses the same
Transition-minimized differential signaling (TMDS) as HDMI to carry video, audio, and auxiliary data. However, MHL differs from HDMI in that there is only one
differential pair to carry the TMDS data lane, compared to HDMI's four (three data lanes, plus the clock). Therefore these three logical data channels are instead
time-division multiplexed into the single physical MHL data lane (i.e., with the logical channels sent sequentially), and the clock signal carried as a common mode signal of this pair.
From MHL 3 onwards, the method for carrying the clock signal changed to being carried separately on the MHL CBUS pin instead.
The normal (24 bit) mode operates at 2.25 Gbit/s, and multiplexes the same three channel, 24 bit color signal as HDMI, at a pixel clock rate of up to 75 MHz, sufficient for
1080i

720p
720p (720 lines progressive) is a progressive HD signal format with 720 horizontal lines/1280 columns and an aspect ratio (AR) of 16:9, normally known as widescreen HD (1.78:1). All major HD broadcasting standards (such as SMPTE 292M) includ ...
at 60 Hz. One period of the MHL clock equals one period of the pixel clock, and each period of the MHL clock transmits three 10-bit TMDS characters (i.e., a 24-bit pixel, where each 10-bit TMDS character represents an encoded byte – 8-bits).
MHL can also operate in PackedPixel mode at 3 Gbit/s, catering for

, in this case only two channels are multiplexed, as the color signal is changed to a
chroma subsampled (YCbCr 4:2:2) pair of adjacent 16-bit pixels (i.e., where two adjacent pixels share chroma values and are represented with only 36-bits), and the pixel clock is doubled to 150 MHz. In this mode, one clock period of the MHL clock now equals two periods of the pixel clock, so each period of the MHL clock transmits twice the number of channels i.e., four 10-bit TMDS characters (a pair of 16-bit pixels).
Version 3 of MHL changed from being frame-based to a packet-based technology,
and operates at 6 Gbit/s. superMHL extends this by carrying the data signal over more than one differential pair (up to four with USB Type-C, or a total of six using a superMHL cable) allowing up to 36 Gbit/s.
Versions
All MHL specifications are backward compatible to previous versions of the standard. MHL is connection agnostic (i.e., not tied to a specific type of hardware connector). The first implementations used the 5-pin MHL-USB connector described below, and all are supported over USB Type-C MHL Alternate Mode. Other proprietary and custom connections are also allowed.

Version 2.0 was introduced in April 2012, and raised the minimum charging supply to 4.5 W (900 mA), with an optional 7.5 W (1.5 A) maximum allowed. Support for 3D video was also introduced, permitting 720p/1080i 60 Hz, and 1080p 24 Hz 3D video modes. The specification also included additional MHL sideband channel (MSC) commands.
MHL 3
Version 3.0 was introduced in August 2013, and added support for
4K Ultra HD (3840 × 2160) 30 Hz video, increasing the maximum bandwidth from 3 Gbit/s to 6 Gbit/s. An additional YCbCr 4:2:0 pixel encoding for 4K resolution was also introduced, while the maximum charging supply was increased to 10 W (2 A).
Support for compressed lossless audio formats was added with support for

and
DTS:X, with an audio-only mode also available. The Remote Control Protocol (RCP) was also extended to link multiple MHL devices together (e.g., TV, AVR, Blu-ray Disc player) and control them via one remote.
The specification introduces a reversible 32-pin superMHL connector, which (along with USB Type-C) supports a higher charging power of up to 40 W (20 V / 2 A), and is designed for future bandwidth expansion. The increase in bandwidth over previous MHL versions is achieved by using multiple A/V lanes, each operating at 6 Gbit/s, with a maximum of six A/V lanes supported depending on device and connector type.
For example, Micro-USB and HDMI Type-A support one A/V lane, USB Type-C supports up to four A/V lanes, and the superMHL connector supports up to six A/V lanes (36 Gbit/s).
In addition to supporting a variable number of lanes, the specification supports

(DSC) 1.1, a "visually lossless" (but mathematically lossy) video compression standard. In cases when the bandwidth of the available lane(s) is unable to meet the rate of the uncompressed video stream, bandwidth savings of up to 3:1 can be achieved with a DSC compression rate of 3.0×.
For example, 4K 60 Hz is possible using a single lane (e.g., Micro-USB / HDMI Type-A) with a DSC rate of 3.0×.
superMHL can use a variety of source and sink connectors with certain limitations: micro-USB or proprietary connectors can be used for the source only, HDMI Type-A for the sink only, while the USB Type-C
and the superMHL connectors can be used for the source or sink.
Connectors

). There are two types of connection, depending on whether the display device directly supports MHL.
Passive cable
Passive cables allow MHL devices to connect directly to MHL-enabled TVs (i.e. display devices or AV receivers with an MHL-enabled HDMI port) while providing charging power upstream to the mobile device. Other than the physical connectors, no USB or HDMI technology is being used. Exclusively MHL signaling is used through the connectors and over the cable.
Active adapter
With an active adapter, MHL devices are able to connect to HDMI display devices that do not have MHL capability by actively converting the signal to HDMI. These adapters often feature an additional Micro-USB port on them to provide charging power to the mobile device because standard HDMI ports do not supply sufficient current.

, and later
Galaxy Note II and
Galaxy S4, use an 11-pin connector and the six additional connector pins in order to achieve functional improvements over the 5-pin design (like simultaneous USB-OTG use
). However, if consumers have a standard MHL-to-HDMI adapter all they need to purchase is a tip. With the launch of the Samsung Galaxy S4, Samsung also released MHL 2.0 smart adapter with a built-in 11-pin connector. The first Samsung MHL 1.0 smart adapter released with the Galaxy S III requires external power and is able to work with HDMI TVs at 1080p at 24 Hz.
The MHL 2.0 adapter released with the Galaxy S4 can output 1080p at 60 Hz and does not need external power.
USB Type-C (MHL Alternate Mode)
The MHL
Alternate Mode for
USB 3.1 specification allows MHL enabled source and display devices to be connected through a USB Type-C port. The standard was released on November 17, 2014, and is backward compatible with existing MHL specifications: supporting MHL 1, 2, 3 and superMHL. The standard supports the simultaneous transfer of data (at least

, allowing devices to connect to other peripherals while charging. The use of passive cables is possible when both devices support the standard, e.g., when connecting to superMHL, USB Type-C, and MHL-enabled HDMI, otherwise, an active cable adapter is necessary to connect to standard HDMI devices.
Depending on the bandwidth requirement, the standard makes use of a variable number of USB Type-C's four SuperSpeed differential pairs to carry each
TMDS lane: a single lane is required for resolutions up to
4K/60 Hz, two lanes for 4K/120 Hz, and all four lanes for
8K/60 Hz.
The MHL eCBUS signal is sent over a side-band (SBU) pin on the USB Type-C connector. When one or two lanes are used, USB 3.1 data transfer is supported.

In common MHL Alternate Mode implementations, the video from the
GPU will be converted to an MHL signal by using an MHL transmitter chip. The transmitter chips often accept video in

superMHL (32-pin)
In conjunction with the release of the superMHL specification in January 2015, MHL introduced a reversible 32-pin superMHL connector. The connector can carry six A/V lanes over six differential pairs, catering for the full 36 Gbit/s bandwidth available from the superMHL standard. The connector also enables 40 W of charging power at a higher voltage and current.
