Abstract

The disclosed method discloses embedded type software application architecture (ETSAA) oriented to instrument equipment in multimedia category. The method is established based on a set of embedded type software application component library oriented to digitalized instrument equipment in multimedia category, especially a multimedia dedicated component library. The invention realizes service function flow of multimedia application system, and provides audio and video codec with powerful functions. In the method, a platform installation of embedded system of instrument equipment in multimedia category provides tools and environment support for fast developing. Since the said ETSAA oriented to instrument equipment in multimedia category is passed the functional validation, the invention shortens development cycle greatly, and reaches standardization, modularization, and reusability of system software.

Description

technical field [0001] The invention relates to a method and device for developing an embedded system of digital multimedia instruments and equipment, in particular to a method and a device for rapidly developing an embedded system of multimedia instruments and equipment using a software framework. Background technique [0002] The combination of audio and video technology, communication and image technology and other multimedia technologies with digital instruments has given new functional services to instruments and equipment, and the scale of a large number of multimedia instruments and equipment (such as consumer electronics and video surveillance, etc.) has grown explosively. At present, in the field of production and life, multimedia instruments and equipment have a wide range of applications, and the application requirements are increasingly updated. The structure of existing digital multimedia instruments and equipment is generally as follows: figure 1 As shown, it ...
