The recently standardized Scalable Video Coding(SVC) extension of H.264/AVC allows bitstream scalability
with improved rate-distortion efficiency with respect to the classical Simulcasting approach, at the cost of an
increased computational complexity of the encoding process. So one critical issue related to practical deployment
of SVC is the complexity reduction, fundamental to use it in consumer applications. In this paper, we present a
fully scalable fast motion estimation algorithm that enables an excellent complexity performance.
H.264 is an emerging video coding standard, providing significant improvements with respect to its ancestors, like MPEG-2 and MPEG-4. In this paper, we present an evaluation of the most important H.264 coding tools in terms of visual quality and compression efficiency
