Method for caption stacking in embedded type product

Abstract

The invention relates to an embedded technique that solves the problem that an embedded system does not have a player with caption function, a method for superposing the caption in an embedded production is provided, the technique proposal can be generalized that a method for superposing the caption in the embedded production comprises the following steps of: a, setting a thread designated to be responsible for analysis work of the caption and extracting caption information from the caption file; b, setting a timer in a player module to ceaselessly acquire the current play time from the player module per a fixed period, and to correct errors; c, judging whether word superposition start time is smaller than the current playing time by circularly comparing the current playing time with the word superposition start time derived from the caption by means of the system, if not, waiting is carried out, if so the next step is implemented; d, superposing the caption via an OSD system. The invention has the beneficial effects of providing convenience to users and adapting to the embedded products with the function of playing audios and videos.

Description

technical field [0001] The invention relates to embedded technology, in particular to the technology of audio and video playback function in embedded products. Background technique [0002] Nowadays, no matter the CDs or movies we download on the market, there are a lot of movie files with subtitles, especially those foreign versions, which need a player with subtitles to play, just imagine For a moment, if it is a very wonderful film, but you don’t understand the meaning expressed by the protagonist in the film, it is very painful.
