Abstract
With the rapid development of information technology characterized computer and network, digital technology products have become the mainstream of the times ,and the digital video technology will undoubtedly reshape the face of the entire electronics industry
Of course, electronics digital video technology is enabling us to experience the video transmission and interactive profound changes. It have begun to enter their car, computer, mobile phone and network. But the enjoyment of high quality is only the beginning of exciting. Lie in in front of many engineers about the main obstacles is the lack of enough with the performance, cheap enough, flexibility, high enough to reach the digital video development platform. And Texas Instruments (TI) DaVinci (DaVinci) technology make it to become true! DaVinci technology enables developers to make use of components flexibly , achieving introduction of rapid mass production of high-performance test design without having to understand the implementation details of the video and do those useless duplication of development efforts, innovation will be possible.Davinci technology will be used for a wide range of productions, such as IP video phones, set-top boxes, digital media players, video surveillance equipment, etc. In this article we used in the field of security DVR as an example to study software interface design approach.
