3 MHL Introduction Mobile HD Link (MHL) technology is a low pin count HD audio and video interface that connects portable electronics devices such as mobile phones, digital cameras, camcorders and portable media players, to HDTVs. The technology allows mobile devices to output digital 1080 Full HD resolution via the existing mobile connector without the real estate and cost of another dedicated video connector Together with an MHL-to-HDMI bridge, the MHL-enabled mobile device becomes a fully compliant HDMI source and can connect to the television s standard HDMI input port.

4 MHL Introduction (Mobile Device Challenges) USB, HDMI - Additional connector difficult for small form Mobile optimized HD connectivity solution needed Optimized for connecting mobile devices to HDTVs and displays Use existing mobile connector without need to add another connector No limit to device form factors large or small mobile devices No consideration of another hole in mobile device Battery life MHL provides endless media playback MHL displays powers MHL mobile devices

9 MHL overview MHL carries video, audio and auxiliary data from an MHL Source to an MHL Sink Consist of Source devices and Sink devices All MHL output ports shall follow the rules for an MHL Source All MHL input ports shall follow the rules for an MHL Sink MHL Dongle shall, in general, meet all the requirements of an MHL Sink Multiple logical channels are multiplexed onto one physical channel (modulated by a clock signal)

10 MHL overview Single, high-speed, differential signal pair the TMDS Channel TMDS encoding in the Source converts the 8 bits of data into a 10 bit DC-balanced. MHL Source and Sink Block Diagram 24 bit mode Pixel clock rate : up to 75MH, 720p/1080i PackedPixel mode Pixel clock rate : Higer than 75MHz, 1080p/60video MHL carries a single-wire Control Bus (CBUS). Configuration and status exchange between single source and single Sink Point-to-point single-wire bus carrying VESA defined DDC(Display Data Channel) commands Source device to read the Sink s Enhanced Display Identification Data (EDID) ROM Content protection CBUS replaces the DDC bus

11 MHL Encoder/Decoder overview 24 bit mode MHL Encoder/Decoder Overview 24-Bit Mode Single differential channel to transmit TMDS data Incoming 3-channel data needs to be packed into one TMDS channel on the TX side and unpacked into 3 channels on the RX side One clock period of the pixel clock equals one period of the MHL clock Physical and Logical Channels One Physical Channel, composed of the single differential pair carrying TMDS data Logical Channels composed of the three data streams(ch0,ch1,ch2) for 24 bit mode

12 MHL Encoder/Decoder overview PackedPixel mode MHL Encoder/Decoder Overview PackedPixel Mode Only two channels are multiplexed: Channel 0 and Channel 1 One clock period of the MHL clock equals two periods of the pixel clock Each period of the MHL clock transmits four TMDS characters

13 MHL overview Period Clock time period (T MHL ) Data bit time (T BIT ) Pixel clock time period (T PIXEL ) 24-bit mode (physical layer level) T MHL = T PIXEL T PIXEL = 30 * T BIT PackedPixel mode (physical layer level) T MHL = 2 * T PIXEL T PIXEL = 20 * T BIT

14 MHL overview Video 24 bit mode RGB 4:4:4 ; YCbCr 4:4:4 ; YCbCr 4:2:2 24 bit Default pixel encoding: RGB 4:4:4, 8 bits/component PackedPixel mode It encoding maps the 8-bit YCbCr 4:2:2 data onto two Logical channels It doesn t support encoding of RGB and YCbCr 4:4:4 Audio The behavior within Audio Sample Subpackets shall follow the corresponding rules specified in the IEC or IEC specifications. PackedPixel Encoding : 8-bit YCbCr 4:2:2 data

15 MHL overview

16 MHL Signal Complexity 1 Clock rate / Date rate 24Bit mode: Max. 75MHz MHL clock rate and 2.25GHz date rate (1080i/60Hz) Packed Pixel implementation( increased from 2.2GBps to 2.97GBps) Packed Pixel mode : Higher than 75Mhz ( 1080p/60 video )- Higher than 75Mhz TMDS (Transition Minimized Differential Signaling) encoding in the Source converts the 8 bits of data into a 10 bit Pack 3 data lanes and 1 clock lane into one lane Video mode minimum support requirement 720x480p / 60Hz or 720x576p / 50Hz Packed Pixel mode : ( 1080p/60 video )
