The information processing apparatus includes: a display control unit that, in a case where display of a video is switched from a first display unit to which a first video signal is input via a first bus to a second display unit to which a second video signal is input via a second bus, causes the first display unit to transition from an activated state in which operation is performed in a light-emitting state to a standby state in which operation is performed in a non-light-emitting state or a stopped state in which operation is stopped in the non-light-emitting state, and causes the second display unit to transition from the standby state or the stopped state to the activated state. The present technology can be applied to, for example, an imaging apparatus.

Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently transmitting uplink signals to a base station using shared antennas. A first device may be in communications with a base station using local antennas and may identify a second device having auxiliary antennas available for transmitting uplink signals to the base station. Because the local antennas and auxiliary antennas may have different capabilities (e.g., due to different power or other constraints), the first device may generate first uplink signals for transmission using the local antennas differently from second uplink signals for transmission using the auxiliary antennas. The first device may transmit the first uplink signals to the base station using the local antennas and transmit the second uplink signals to the second device for transmission to the base station using the auxiliary antennas based on different configurations.

A receiving device obtains touch screen instruction from a touch screen via an interface of a first transmission medium, and the touch screen instruction comprises a user operation input to the touch screen. The receiving device superimposes a common mode signal obtained by processing the touch screen instruction with a differential mode signal obtained through processing the differential signal to obtain a mixed signal comprising the touch screen instruction.

A display device includes a control circuit, an array of LED zones, and an array of driver circuits that are distributed in the display area. The driver circuits are arranged in groups that are connected in a serial chain by a set of communication lines. The group of driver circuits are configurable between a serial communication mode and a parallel communication mode. In the serial communication mode, each driver circuit receives an incoming signal on an input pin, processes the signal through serial communication logic to generate an outgoing signal, and outputs the outgoing signal to an output pin such that the driver circuits serially process the incoming signal. In the parallel communication mode, each driver circuit transfers the incoming signal from the input pin to the output pin bypassing the serial communication logic such that all driver circuits in the group can process the incoming signal in parallel.
