Multi-layer architecture unit, operation method and compression method for recording video and audio frame data

Abstract

The present invention relates to a multi layer framework unit, operating method and compressing method for recording video and audio framework data. The multi layer framework unit at least comprises a shared control layer, a task control layer, and a film format control layer, wherein, the shared control layer is used to control the compression program of the video and audio framework data, and manage of ring queue, the task control layer comprises a plurality of control units, and collocated and stored with the ring queue to execute the task needed for capturing the video and audio framework data, at last, the file format control layer construct the video and audio framework data into a file. Thereby, the purpose to improve the extensibility, maintainability and readability of the software program can be reached by the multi layer framework unit for capturing the video and audio framework data.

Description

technical field [0001] The invention relates to a multi-layer structure unit, its operation method and compression method, in particular to a multi-layer structure unit for recording audio-visual framework data, its operation method and a method for compressing the audio-visual framework data task. Background technique [0002] With the advancement of technology, the mobile phones on the market are equipped with more and more functions, and various multimedia functions have been integrated to enrich the added value of mobile phones to attract users' attention. The use of Charge-Coupled Devices (CCD) is not only used to produce the original function of integrating digital cameras in mobile phones, but also has been developed to enable dynamic video recording. [0003] In the known technology, the firmware architecture used to process the dynamic recording function is a single-level design, which integrates all shared control programs, specific execution programs, and file for...

Problems solved by technology

[0004] However, under this design, the entire software program must be greatly changed when it is modified for customization, and the program has low scalability and is not easy to implement.

The maintenance of the format of the stored files is also relatively complicated, and the readability of the entire program is not high, which leads to the fact that the R&D personnel need to modify the entire software architecture no matter whether it is adding new functions or maintaining the architecture. above trouble

In addition, in the temporary storage and execution of the underlying data, the efficiency of writing files will be poor due to the use of a linear structure shared queue, and the speed of file storage is therefore limited.
