How to connect Phone to TV
Mobile High-Definition Link (MHL) is an industry standard for a mobile audio/video interface that allows the connection of mobile phones, tablets, and other portable consumer electronics (CE) devices to high-definition televisions (HDTVs) and audio receivers. MHL-enabled products include adapters, automotive accessories, AV receivers, Blu-ray Disc players, cables, DTVs, media sticks, monitors, projectors, smartphones, tablets, TV accessories and more. MHL is a consortium made up of major companies in the mobile and CE industries, including Nokia, Samsung, Silicon Image, Sony and Toshiba.
MHL was originally intended for mobile devices such as smartphones and tablets.
High-definition video and eight-channel surround sound.Encrypted video and audio via High-bandwidth Digital Content Protection (HDCP).Transition Minimized Differential Signaling (TMDS) for video, audio, and auxiliary data.5-volt DC power on the cable.HDMI-CEC control of remote devices.
To better accommodate the needs of mobile devices, MHL differs from HDMI as follows.
Five wires in place of HDMI’s nineteen, namely ground, power, control, and a differential pair for data. This permits a much lighter cable and a much smaller connector on the mobile device.Whereas HDMI uses the power line to provide 5 volts from the source at 50 mA (0.25 W) for the purpose of awakening a sleeping sink, MHL uses it to provide that voltage from the sink at 900 mA (4.5 W) to maintain the state of charge of the source. This allows a mobile device with only one port for both charging and MHL to operate indefinitely without exhausting the battery, provided 4.5 W is sufficient. Devices needing more power from the port used for MHL may not be suitable candidates for MHL 2.0; MHL 3.0 raises the power requirement to 2 A (10 W).Although MHL ports can be dedicated to MHL alone, the standard is designed to permit port sharing with the most commonly used ports.A typical MHL source will be shared with USB 2.0 on a standard 5-pin micro-usb receptacle, which switches from USB to MHL when it recognizes an MHL-qualified sink detected on the control wire.A typical MHL sink will be shared with HDMI on a standard 19-pin HDMI receptacle. The standard uses the same pins for power (pin 18) and ground (pins 5, 11, and 17), HDMI’s Hot Plug detect (pin 19) for MHL control, and HDMI’s Data0 channel (pins 7 and 9) for MHL’s data.Whereas HDMI transmits the three bytes of a pixel in parallel over three physically separate differential pairs along with a fourth pair for a clock, with a separate ground for each pair (pins 1-12), MHL transmits them sequentially over one pair (7 and 9), with the clock added in as a common mode signal to the differential signal. The receiver then has both differential and common mode detection circuits. In MHL 3 and superMHL the clock signal is instead carried separately on an extended CBUS, renamed the enhanced control bus (eCBUS).Whereas HDMI uses three wires to cater for HDMI-CEC (13), and DDC (15 and 16), MHL controls these functions with a single wire (CBUS).In normal mode MHL supplies the same 24 bit color signal as HDMI, at a pixel clock rate of up to 75 MHz for MHL 2.0, sufficient for 1080i and 720p. Each of the three bytes is in a 10-bit frame whence at 75 MHz the data channel operates at 2.25 Gbit/s.MHL 2.0 caters for 1080p with a PackedPixel mode utilizing only the first two of HDMI’s three channels. This shrinks each pixel to 16 bits (using YCbCr 4:2:2 chroma subsampling) carried in two 10-bit frames. The pixel clock is doubled to 150 MHz and the data channel then operates at 3 Gbit/s.MHL’s serial signaling makes it incompatible with the three-channel parallel signaling of HDMI and DVI. Hence both ends of an MHL channel must implement the standard in full. In particular an MHL source cannot drive an ordinary HDMI or DVI display, though this limitation is easily overcome with an MHL dongle converting MHL to HDMI. An MHL source must be realized in hardware as the typical 5-pin USB 2.0 port on mobile devices is much too slow at 480 Mbit/s for a software-only implementation
