HEVC/H.265 standard was released in 2013. It allows reducing by half the required bandwidth in comparison with the previous H.264 standard. This opens the door to many relevant applications in the multimedia video coding and transmission context. Thanks to the HEVC improvements, the 4K and 8K Ultra High Definition Video real time constraints can be met. Nonetheless, HEVC implementations require a vast amount of resources. In this contribution we propose intra and inter prediction techniques in order to diminish the HEVC complexity, while complying with the real time and quality constraints. The performance is noticeably increased when comparing with respect to the HM16.2 reference software as well as the x265 encoder, maintaining a similar quality too.
