Audio and video play progress control method, apparatus and system

Abstract

The invention discloses an audio and video play progress control method, apparatus and system. The method comprises the following steps: obtaining the total time length T of currently played audio and video; according to the total time length T of the audio and video, generating a corresponding progress strip total length L positively correlated with the T, and displaying a progress strip on a locus in a predetermined shape according to the L; after a passive movement event of a play pointer of the progress strip is monitored, obtaining the current position of the play pointer, and determining the play time point t corresponding to the current position of the play pointer; after the passive movement event of the play pointer, obtaining the content of the audio and video started from the play time point t corresponding to the current position of the play pointer; and playing the content of the audio and video started from the play time point t corresponding to the current position of the play pointer. By using the method, apparatus and system provided by the invention, the control accuracy of the play progress of the audio and video can be improved.

Description

technical field [0001] The present application relates to the technical field of human-computer interaction of smart devices, in particular to a method, device, and system for controlling audio and video playback progress. Background technique [0002] Human-computer interaction technology (Human-Computer Interaction Techniques) refers to the technology that realizes the interaction between human and machine in an effective way through the input and output devices of the machine. It includes that the machine provides a large amount of relevant information and prompts to people through output or display devices, and people input relevant information and operating instructions to the machine through input devices. [0003] In today's work and life, intelligent terminals with data processing capabilities, such as computers, mobile phones, handheld computers, tablet computers, smart TVs (Smart TV), etc., have been widely used. In particular, portable smart terminals such as mob...

Problems solved by technology

[0006] However, in the existing control method of this audio and video playback progress, the background progress bar is fixed, and the progress jump position is calculated by the position of the playback pointer relative to the progress bar. Although the operation is simple, the It is difficult for the user to accurately control the range of fast forward and rewind during the operation, especially for audio and video files with a long playing time (such as a movie of more than 1 hour), it is often difficult to accurately jump to the the desired position

Especially in portable smart terminals with small screens, this shortcoming is particularly prominent
