MHL and USB interface

Another advantage of MHL is that it can transmit all kinds of signals.\" Eidson said. As we can see, mobile phone is very different from TV in that it can support multiple media formats, including MPEG4, h.264, AVI, Quick time, or Windows media, or even RM/RMVB. Traditionally we use USB interface to its docking with the TV, but this is a bad place, because of the TV after receiving these signals to the signal of decompression and decryption, the process will damage the signal clear degree, the MHL made in the process of transmission of TV without unzipping link, so the signal can be intact transmission for high-definition TV and broadcast, support various formats of signal quality from any damage.

     He further explained that by design, some manufacturers would choose a standard USB connector to connect to a PC, in which case another MHL connector would be needed. However, there are some vendors that want a single connector to do all the work, so it's possible to make USB and MHL use the same connector, \"but MHL doesn't need a special connector. It is a 5Pin interface, so it can be plugged into an existing or new custom connector. Examples of this are apple's iPod connector and Microsoft's Zune connector.\" He added.
 \"The other big benefit of the MHL interface is that it will make your TV set forever adaptable to the transmission requirements and trends of emerging media, so you won't need to replace your TV for a long time. We know that mobile phone and some filming equipment replacement frequency is very high, but the investment for the masses of the user of the television once he hope this TV set to use for many years, so have the MHL interface, it can make accept multiple formats of high-definition television signals, dispense with replacement of the additional investment of the television.\"
