MP3 : OTG Technology

USB OTG is an acronym for USB On-The-Go. It is a technology developed in recent years. It was announced by the USB Implementers Forum on December 18th, 2001. It is mainly used for connection between various devices or mobile devices to exchange data. Especially PDAs, mobile phones, consumer devices. The inconvenience of data exchange between memory cards of up to 7 formats has changed for devices such as digital cameras, video cameras, and printers.

With the development of USB technology, PCs and peripheral devices can connect devices with various data transmission speeds through simple methods and moderate manufacturing costs. We mentioned that the applications mentioned above can all use the USB bus as peripherals of PCs and PCs. Under the control of data exchange. But this kind of convenient exchange way, once left the PC, each device can't use the USB mouth to operate, because no slave device can act as Host of PC.

On-The-Go, that is, OTG technology is to realize the data transmission between devices without Host. For example, the digital camera is directly connected to the printer, and the OTG technology is used to connect the USB ports seen by the two devices to print out the photographs immediately. The data in the digital camera can also be sent to the USB hard disk via OTG. There is no need to carry expensive memory cards in the field or to carry a laptop.

In OTG products, some new features have been added:

* New standard for designing compact connectors and cables;

* In the traditional peripheral devices, Host capabilities have been added to accommodate point-to-point connections;

* This capability can be dynamically switched between two devices;

* Low power consumption, to ensure that USB can work under battery power. After using OTG, it does not affect the connection between the original device and the PC, but it makes the device with more than 1 billion USB interfaces in the market, and can also be connected through OTG.
