Abstract

Transmission and storage of video data has necessitated the development of video com pression techniques. One of today's most widely used video compression techniques is the MPEG-2 standard, which is over ten years old. A task force sponsored by the same groups that developed MPEG-2 has recently finished defining a new standard that is meant to replace MPEG-2 for future video compression applications. This standard, H.264/AVC, uses significantly improved compression techniques. It is capable of providing similar pic ture quality at bit rates of 30-70% less than MPEG-2, depending on the particular video sequence and application [20].

This thesis developed a complete VHDL behavioral model of a video decoder imple menting the Baseline Profile of the H.264/AVC standard. The decoder was verified using a testing environment for comparison with reference software results. Development of a synthesizable hardware description was also shown for two components of the video de coder: the transform unit and the deblocking filter. This demonstrated how a complete video decoder could be developed one module at a time with individual module verifica tion. Analysis was also done to estimate the performance and hardware requirements for a complete implementation on an FPGA device.
