Interactive parallel video editing using FPGA structures

In this thesis, a real time video processing system is proposed and it is implemented on a Field Programmable Gate Array (FPGA) platform. 3D video applications including frame sequential video, field sequential video and anaglyph video are implemented by using the parallel processing feature of the FPGA. In addition, other common industrial applications such as picture in picture and chroma keying are added to the system.This thesis is realized on Altera DE2-70 FPGA development board and is divided into two parts. In the first part, the video frames from a single camera is buffered in the FPGA board and sent to the monitor without any additional video processing operations. In the second part, the second camera is added to the system. In this proposed video processing system, two video sources are used for the parallel video applications. Firstly, composite video inputs in NTSC format are converted to digital video format. TV decoder ICs are used to decode the analog video inputs. Then, SDRAMs are used to buffer the video frames. All the video preprocessing operations and video applications are implemented in FPGA hardware. Finally, the parallel video applications are combined into one design and implemented. The processed video is sent to the VGA output of the board.In order to evaluate the processed video, some special devices are also used. Head mounted display is used for the frame sequential video application and colored glasses are used for anaglyph video application.
