Architektury a optimalizace pro kompresní algoritmy k dosažení nízkého zpoždění realizované v (programovatelných) technických prostředcích

Abstract

This dissertation thesis focuses on researching which compression algorithms are suitable for a very specic use case of real-time multimedia transmission systems such as CES-NET's MVTP, providing excellent image quality and low-latency operation at the same time. However, the MVTP's throughput requirements exceeding the capabilities of used communication interfaces slightly in certain situations. Because no hardware implement-ations of universal lossless compression algorithms met the MVTP's requirements, some new hardware-based optimizations and architectures had to be discovered. Some of these optimizations were inspired by software implementations of so-called \fast" lossless com-pression algorithms, which trade a worse compression ratio for a better compression speed.
