Abstract: An intelligent system for controlling driving of an aircraft tow tractor by means of combination of voice and vision includes an audio transmission line, a voice recognition system, a visual recognition system, and a vehicle-mounted motion controller. According to the intelligent system, visual recognition is performed based on a belly-mounted anti-collision light on an aircraft, a taxi light, and the visual recognition system on an aircraft tow tractor, and the aircraft tow tractor is intelligently controlled by means of combination of voice recognition and the visual recognition; furthermore, the aircraft tow tractor is intelligently controlled by voices of flight crew via the audio transmission line, safety in a towing process is guaranteed by the visual recognition, and each step in the towing process is performed by means of a cross validation based on the voice recognition and the visual recognition.

Abstract: A control method for playing media includes receiving an input from a user for triggering a play progress adjustment to the media playing on a screen. The method also includes generating an instruction for play progress adjustment based on the input. The instruction includes an adjustment manner, a target position and a start position of the input. The method further includes determining a target key frame immediately before a target time corresponding to the target position. The method additionally includes decoding data of the media starting from the target key frame and blocking presentation of the decoded media data starting from the target key frame. The method also includes playing media data decoded starting from the target time in response to a system time clock progressing to the target time.
