Özet:Video compression is a key technology used in several multimedia applications. Improvements in the compression techniques together with the increasing speed and optimized architecture of the new family processors enable us to use this technology more in real time systems. H.264 (also known as MPEG-4 Part 10 or AVC - Advanced Video Coding), is the latest video coding standard which is noted for achieving very high data compression. While H.264 is superior to its predecessors, it has a very high computational complexity which makes its costly for real time applications. Thus, in order to perform video encoding with satisfactory speed there is an obvious need for reducing the computational complexity. New algorithms were developed for this purpose. The developed algorithms were implemented on Texas Instrument TMS320C64x family to be able to fulfill the requirement in optimized signal processing hardware with low power consumption which arises from the computational complexity and the need for portable devices in video processing technology. With the new algorithms developed, a computation reduction of 55% was achieved without loosing perceptual image quality. Furthermore, the algorithms were implemented on a DSP along with the networking functionality to obtain a video streaming system. The final system may be used in a wide range of fields from surveillance systems to mobile systems.
