Computer readable recording media and device for recording multimedia file

Abstract

The invention relates to a readable media of a computer used for recording a multimedia file with audio/video synchronization and a device with audio/video synchronization. A recording media which records a making program of a multimedia data file and is used in the computer allows the following modules to give play to functions: a data input module which is provided with inputting and sampling video data and audio data; an index generation module which samples and labels index information from the video data in turn; an index corresponding module which divides the audio data into certain intervals and generates corresponding information of the index information and the divided regions and intervals; an audio analysis module which transfers the audio data to the regions with characteristic number in a certain cycle and labels the index information according to the corresponding information; and a file handling area is formed to record the audio data and labeled data series, at the same time, a file generation module of the multimedia data file is generated according to the labeled index information. The invention can not only reduce the utilization of hardware resource of mobile communication terminals, but also automatically synchronize music and image.

Description

technical field [0001] The present invention relates to audio frequency, video synchronous multimedia data file and audio frequency, video synchronizing device, relate to audio frequency, video synchronous use media data file production software as a kind of computer of programming and record the multimedia file that is used for audio / video synchronous Computer readable medium and audio / video synchronization device. Background technique [0002] Now, personal portable terminals such as mobile phones, PDAs (Personal Digital Assistants), smart phones, etc. are becoming necessary tools of life in the real world. In addition to the basic communication functions, these personal portable terminals also provide multiple functions such as e-mail functions, game functions, camera functions, recording functions, music playback functions, still image and moving image playback functions, and the like. [0003] Especially recently, personal portable terminal products are being developed...

AI Technical Summary

Problems solved by technology

[0010] However, when reading audio data by audio, the audio and video synchronizing device must execute excessive calculation procedures in real time. Therefore, the hardware resources of the mobile communication terminal equipped with the audio and video synchronizing device are overloaded.
