Mobile High-Definition Link (MHL)

New standard first used in the Samsung Galaxy S2 to output HD and charge at the same time through the Micro-USB connector, it also allows for some data to be sent back from HDTVs such as using the TVs standard remote control to also remote control the device. The MHL 1.0 spec does not transmit Gigabit Ethernet or USB 3.0 Host functionality for now.

MHL sucks, you can't use usb + hdmi so no desktop possibility for phones. Smart move Samsung that's gotta sell 2 extra tablets ans saves 20 cents per phone for a standart mini usb + hdmi connector.

I think the port can do USB host at the same time as the HDMI, it can send data from the external device back to the phone. That is why MHL can supporty ou using your MHL compatible TV remote to control your phone. The question is just when are the MHL makers going to release adapters that also use USB Host, for example I think there is space on the MHL adapter for a USB host port.

[Steven de Feij]

No it can't it can charge the device but USB + HDMI is NOT possible.

Either USB or HDMI is possible.

But I really hope I'm wrong but untill that changes I'm boycotting Samsung and HTC.

[Charbax]

I'm pretty sure you are wrong. Otherwise data/key inputs would not be able to go back from MHL TV remote to the phone. The USB Host functionality is just a question of the device/adapter/dock connecting to the phone supporting that and the phone understanding the signal, which I am pretty sure it already does. For example, if you MHL TV remote includes full keyboard, then full keyboard inputs are now sent over MHL same as USB host, and your MHL TV mice/directional inputs are also recognized.

[Steven de Feij]

I'm pretty sure I'm not, the return channel is a propriotaire protocol called RCP, not USB or USB OTG compatible, only "usb" charging is possible.

So once again we are getting screwd but they try to convince us it good news.

This is HDCP all over again.

[Charbax]

USB is not a proprietary technology, and the USB port is not a proprietary design, MHL can use both at the same time, they just don't market it as that. The thing is most consumers do not use HDMI and USB Host much, 95% of consumers barely use HDMI yet and if they use Keyboard/Mice input they use wireless Bluetooth for now. That does not prevent some MHL accessory maker from releasing a special USB Host enabled MHL adapter, with 1 to 4 full sized USB host ports on the side, or an MHL LapDock.

The interviewer and interviewee were both well versed in the technology and highly informed. Absolutely great information and interview!

[Charbax]

I think that was before MHL standard, but that after everyone implement the standard, then all devices will work with all HDTVs.

[fleXTheConsoleGuy]

"That does not prevent some MHL accessory maker from releasing a special USB Host enabled MHL adapter, with 1 to 4 full sized USB host ports on the side, or an MHL LapDock"

they want us to buy the all share wireless HDMI DONGLE, that´s Why they don´t release a cheap alternative.

Anyone tryed to modifi the MHL adapter to have an USB data input?

it´s very usefull to play movies that you have in pendrives or to play ROMS that are in your pendrive or external hard disc while you use a joystick

Toshiba, Sony, Samsung..... Sony Samsung... Toshiba, Samsung, Sony and Toshiba?

[vinisr12]

is there actually anywhere documentation specifying restriction of mhl? I am expecting my camera apps will work with the mhl, but it just say "hdmi not available when application is running". Will be nice if someone can share more on this
