A driver circuit includes a first output terminal, a first switch, a second switch, a third switch and a power source. The first output terminal is arranged for outputting a data output. The first switch is selectively coupled between the first output terminal and a power supply node according to a data input. The second switch is selectively coupled between the first output terminal and a first reference node according to the data input. The third switch is selectively coupled between the first reference node and a reference voltage. The power source is configured to selectively provide one of a supply voltage signal and a supply current signal to the power supply node. When the power source is configured to provide the supply voltage signal, the third switch is switched on. When the power source is configured to provide the supply current signal, the third switch is switched off.

The present invention provides for systems and methods of transmitting and converting a landscape image to a portrait image for use in a virtual reality (VR) and augmented reality (AR) environment at a very high speed with negligible latency thus providing a seamless video feed to enhance the VR or AR environment to meet the demands of VR and AR head mounted displays. The present invention further provides for systems and methods for compositing and communicating video, audio, user data, and commands for VR and AR applications with stationary and moving participants. The present invention overcomes the unmet needs of the art by providing a wireless video processing which includes equipment that has a low power consumption, while providing a reliable and seamless virtual or simulated environment. The present invention further overcomes the unmet need by providing systems and methods to reduce the latency caused by image rotation.
