Lossless Video Compression
 Polák, Michael Adam ; Polok, Lukáš (referee) ; Bařina, David (advisor)
This thesis is describing methods of lossless video compression. It also contains the description and formulas for conversions of color models suitable for lossless compression. The last theoretical part describes context compression and entropy coding with emphasis on arithmetic coding. Following the arithmetic coder is the description and details about the implemented video codec. This codec is then tested and compared with the currently used FFV1 and Huffyuv codecs. The result of this thesis is that adding the number of contexts improves the compression ratio although it does not outperform the compression ratio of FFV1, the compression ratio of Huffuyv was always outperformed.

Implementation of video compression into FPGA chip
 Tomko, Jakub ; Fujcik, Lukáš (referee) ; Bohrn, Marek (advisor)
This thesis is focused on the compression algorithm's analysis of MJPEG format and its implementation in FPGA chip. Three additional video bitstream reduction methods have been evaluated for real-time low latency applications of MJPEG format. These methods are noise filtering, inter-frame encoding and lowering video's quality. Based on this analysis, a MJPEG codec has been designed for implementation into FPGA chip XC6SLX45, from Spartan-6 family.
