A transmission that reduces the number of pins when connect to small devices. And all this is possible, because the transmitters are responsible for distributing high-definition audio and video in the five pins that make up the connector.
These types of transmitters are available with input support for Mobile Industry Processor Interface (MIPI) and in RGB/YCbCr/ITU.601/ITU.656 when it comes to digital video input.
- MHL bridge: On the other hand one has I canbefore MHL to HDMI. These are the ones in charge of converting all audio and video signals that come from a device that drives MHL technology to a standard signal that is supported by a device with HDMI connection.
