In a tv box, firmware is a specific class of computer software that provides low-level control for a device’s specific hardware. Firmware contains the basic functions of a device and may act as the device’s complete operating system, performing all control, monitoring, and data manipulation functions, especially including the remote control code, which can take corrective action when the user press any button on the remote control. Such as showing the OSD menu, auto search, and changing volume and channels.

Firmware is held in the memory devices such as ROM or Flash memory. Upgrading by a USB disk, which includes a *.bin file. Upgrade the correct firmware is very important, otherwise, the wrong firmware can not make any corrective action when you press the remote control, and the tv box can lose its function.
