This work presents a hardware design for the Sample Adaptive Offset filter, which is an innovation brought by the new video coding standard HEVC. The architectures focus on the encoder side and include both classification methods used in SAO, the Band Offset and Edge Offset, and also the statistical calculations for the offset generation. The proposed(More)
This work presents a cost function optimization for the internal decision of the HEVC Sample Adaptive Offset (SAO) filter. The optimization approach is focused on an efficient hardware design implementation, and explores two critical points. The first one focus in the use of fixed-point data instead of float-point data, and the second focus on reduce the(More)
This article presents the hardware design of the 16x16 2-D DCT used in the new video coding standard, the HEVC – High Efficiency Video Coding. The transforms stage is one of the innovations proposed by HEVC, since a variable size transforms stage is available (from 4x4 to 32x32), allowing the use of transforms with larger dimensions than used in previous(More)
This paper presents a novel early Skip/DIS mode decision for 3D-HEVC depth encoding which aims at reducing the complexity effort of this process. The proposed solution is based on an adaptive threshold model, which takes into consideration the occurrence rate of both Skip and DIS modes. Occurrence analysis showed that the lower is the Skip and DIS(More)
