The Hardware Design And Implementation Of Infrared Scene Generator And MPEG-2 Coding System

There are two parts in this paper.ln the first part, a new system of real-time infrared scene sequence generation, based on personal computer, is presented. It takes the advantage of the previous real-time scene generator and meets the new requirements. To improve the adaptability and flexibility, a new method which uses a configurable timing-control module is introduced. In the new system, the parameters of scene sequence, such as SNR, resolution, can be configured through software.In the second part, a video coding system based on MPEG-2 standard is discussed. MPEG-2 standard is specified to meet the increasing need of the digital storage media, interactive television, High-Define Television and etc. MPEG-2 standard defines two data structures, i.e., Transport Stream(TS) and Program Stream(PS). The IS offers robustness neceesary for noisy channels. The video coding system discussed in this part can transform the PAL video signal to MPEG-2 TS. It offers an effective method for video signal transmitting.
