Abstract [en]

For good quality Internet video, digital TV, or even mobile video, efficient coding of video signals is required to meet given bandwidth constraints. Today, MPEG-2 and MPEG-4 coding standards are widely used. But to cope with higher than HD resolution more efficient coding is needed. A successor to the MPEG-4 codec is now developed by JCT-VC, a group formed by MPEG and VCEG, with the goal to reduce bit rate by 50%. The working name for this emerging standard is H.265/HEVC (High Efficiency Video Coding). In this thesis three algorithms associated with the loop-filters have been developed and evaluated. The goal is to improve a HEVC test model and possibly contribute to this emerging standard. Results show that deblocking and adaptive Loop filter may be run in parallel, a gain could be achieved by using more input to ALF and fixed filters may considerably reduce complexity of ALF. This thesis was done in cooperation with Ericsson Research.
