| Abstract: | A systemic design to remotely monitor fused fiber splicing based on ADI ADSP-BF533 with real-time characteristics and high precision is described.The analog video signal is digitized in the video decode module ADV7183B and the digital video signal is encoded in the video encode module ADV7171.High capacity external SDRAM memory is used to buffer the digital video frame.The central control and digital video data processing unit is completed in ADSP-BF533.The system can do real time video compression,so analog video from different vidicons can display on the same monitor and the fused fiber splicing process can be remotely monitored. |
