Abstract - Video coding has been one of most explored areas in the last years. Due the high technology growth, mainly in the number of digital video applications, it is necessary to develop new, more robust and modern video/image compression techniques, that will satisfy the needs of the present and future society. The H.264/AVC standard emerged to fulfill these needs.
In the first part of this dissertation, we describe some video signal concepts, some coding techniques and the most important video/image coding standards. Then, it is presented a detailed study of the H.264/AVC standard, where are identified the main features of the standard and its main differences, comparatively to the oldest video coding standards (MPEG-1, MPEG-2, MPEG-4, H.261 e H.263). The experimental part of this work consists in the evaluation and comparison of the H.264/AVC performance with other coding standards. To use some coding standards implementations, it was necessary to develop some manipulation video tools, that are described in the last part of this work.
The results obtained in the simulations show that the H.264/AVC is the standard with the highest performance, regardless of the bitrate used in lossy coding. For the lossless coding, the H.264/AVC does not provide the best compression results.
