Method and apparatus of prompting a position of an aerial vehicle are provided. The method may include: obtaining first position information of the aerial vehicle and second position information of a ground end; and presenting a relative position relationship between the aerial vehicle and the ground end on a preset map according to the first position information and the second position information. Flight status including flight position and other suitable information of an aerial vehicle may therefore be directly provided.

A video signal processing system includes a first video signal processing chip and a second video signal processing chip. The first video signal processing chip determines whether both of a first video signal and a second video signal are in a stable state. After the first video signal processing chip determines that both of the first and second video signals are in the stable state, the first video signal processing chip sends a synchronization signal to the first video processing chip and the second video processing chip. After receiving the synchronization signal, the first video signal processing chip and the second video signal processing chip respectively output a first processed video signal and a second processed video signal to a display device.

Provided are data transmitting apparatuses and methods, data receives apparatuses and methods, and data transceiving systems and methods. A data transmitting apparatus includes: a packet generator configured to generate an audio metadata packet; and a transmitter configured to transmit the generated audio metadata packet to a data receiving apparatus, wherein a header of the generated audio metadata packet includes a split screen information field in relation to audio data represented by the generated audio metadata packet.

An image processing terminal comprises a processor, a memory and a communication unit receives a control signal from a remote controller in response to a selection of a key by a user. One or more programs stored in the memory include instructions for determining whether a sensing level of the key in the received control signal corresponds to a normal press or a force press and executing a control command corresponding to the normal press or the force press. In response to a force press being inputted to the remote controller, the processor performs at least one of change of an object displayed on a screen or a scene transition of contents. An operation of the image processing terminal when a normal press is inputted to the remote controller is different from an operation of the image processing terminal when the force press is inputted to the remote controller.

Imaging systems having multiple optical modules are provided to achieve higher zoom ratio and better displaying effect. The FOVs or focal length ranges of the multiple optical modules may be designed to achieve a zoom ratio higher than either of the multiple optical modules and a Picture-in-Picture function. The gravity center of the imaging system may not be significantly varied during the zooming in and zooming out of the multiple optical modules.
