This paper proposes a reusable design for the merging process used in three-dimensional High Efficiency Video Coding (3D-HEVC), which can significantly reduce the implementation complexity by eliminating duplicated module redundancies. The majority of inter-prediction coding tools used in 3D-HEVC are utilized through a merge mode, whose extended merging process is based on built-in integration to completely wrap around the HEVC merging process. Consequently, the implementation complexity is unavoidably very high. To facilitate easy market implementation, the design of a legacy codec should be reused in an extended codec if possible. The proposed 3D-HEVC merging process is divided into the base merging process of reusing HEVC modules and reprocessing process of refining the existing processes that have been newly introduced or modified for 3D-HEVC. To create a reusable design, the causal and mutual dependencies between the newly added modules for 3D-HEVC and the reused HEVC modules are eliminated, and the ineffective methods are simplified. In an application of the proposed reusable design, the duplicated reimplementation of HEVC modules, which account for of the 3D-HEVC merging process, can be eliminated while maintaining the same coding efficiency. The proposed method has been adopted as a normative coding tool in the 3D-HEVC international standard.

Standardization of a new set of 3D formats has been initiated with the goal of improving the coding of stereo and multiview video, and also facilitating the generation of multiview output needed for auto-stereoscopic displays. Part of this effort will develop 3D and multiview extensions of the emerging standard for High Efficiency Video Coding (HEVC). This paper outlines some of the key technologies and architectures being considered for standardization, and analyzes the viability, benefits and drawbacks of different codec designs.

Encoding High Efficiency Video Coding cideo is a heavy task. GPU multi-threading method is proposed, but due to the spatial and temporal data dependancy there was limitation on performance or quality. Over the last few years, hardware video encoders have been built into many GPUs. Using one of the, We encode various resolution videos with HEVC. Our results show that we can encode video more than 10000 times taster than original software implementation.

Video transcoding is the process of converting compressed video signals to adapt video characteristics such as video bit rate, video resolution, or video codec, so as to meet the specifications of communication channels and endpoint devices. A straightforward transcoding solution is to fully decode and encode the video. However this method is computationally expensive and thus unsuitable in applications with tight resource constraints such as in software-based real-time environment. Therefore, efficient transcoding meth- ods are required to reduce the transcoding complexity while preserving video quality. Prior transcoding methods are suitable for video coding standards such as H.264/AVC and MPEG-2. H.265/HEVC has introduced new coding concepts, e.g., the quad-tree-based block structure, that are fundamentally different from those in prior standards. These concepts require existing transcoding methods to be adapted and novel solutions to be developed. This work primarily addressed the issue of efficient HEVC transcoding for bit rate adaptation (reduction). The goal is to understand the transcoding behaviour for some straightforward transcoding strategies, and to subsequently optimize the complexity/quality trade-off by providing heuristics to reduce the number of coding options to evaluate. A transcoder prototype is developed based on the HEVC reference software HM-8.2. The proposed transcoder reduces the transcoding time compared to full decoding and encoding by at least 80% while inducing a coding performance drop within a margin for 5%. The thesis has been carried out in collaboration with Ericsson Research in Stockholm

For 4K and 8K video services that are capable of providing high definition pictures with an abundant sense of presence, the latest H.265/MPEG-H video coding standard, also known as HEVC (High Efficiency Video Coding), should allow the encoding of huge quantities of video data to be performed effectively and with high compression efficiency.This article introduces HEVC hardware encoder technology that is capable of encoding 4K video in real time.

Kyky tallentaa valtavia määriä videokuvaa vaatii helppokäyttöisiä ja tehokkaita videonkoodausjärjestelmiä, joiden avulla voidaan mukautua rajallisiin lähetys- ja tallennuskapasiteetteihin. Tässä työssä esitellään avoimen lähdekoodin pilvipalvelu, jonka avulla pystyy transkoodaamaan videoita H.265/HEVC-formaattiin. Vaihtoehtoisia kaupallisia toteutuksia on saatavilla, mutta ne ovat maksumuurien takana. Komentorivikäyttöliittymien käyttäminen taas vaatii syvällistä ymmärtämistä pakkausprosessista parhaan mahdollisen laadun ja nopeuden saavuttamiseksi. Esitelty järjestelmä on helppokäyttöinen, avoimen lähdekoodin toteutus, joka tekee siitä helposti lähestyttävän myös ei-teknisesti valveutuneille käyttäjille. Se on rakennettu käyttämällä FFmpeg-multimediatyökalua, jonka avulla pystyy dekoodaamaan paljon erilaisia sisääntuloja sekä Kvazaar-nimistä HEVC-koodainta videonpakkaukseen.

Saliency represents the probability of human attention over the image therefore is important in understanding the importance of different areas in the image. In this paper, we consider how to utilize the saliency information in HEVC video coding. The graph-based visual saliency is incorporated with the quantization control in HEVC to reduce the bit rate of compressed video by using larger quantization parameter for the coding unit which has lower probability of attention. As shown in our experiments, the proposed method achieves up to 12% bit rate reduction without perceptual quality loss.

Videodataa täytyy pakata, jotta sitä voidaan siirtää ja tallentaa järkevästi. Videonpakkaamisalgoritmit muuttuvat jatkuvasti tehokkaammiksi ja kompleksisemmiksi. Jotta videota pystyttäisiin pakkaamaan tehokkaammin samassa ajassa, vaaditaan enemmän konetehoja. Tässä työssä tutkitaan mahdollisuutta hyödyntää internet yhteyttä, ja tämän avulla useampia koneita, hajautetussa videon pakkaamisessa.

HEVC encoders impose several challenges in resource-constrained embedded applications, especially under real-time and battery constraints. This paper proposes a complexity-scalable encoder that is able to achieve considerable time savings while maintaining an efficient rate-distortion-complexity tradeoff. To design the system, a complexity analysis of HEVC-supported parameters as well as new ones introduced in this work is presented. To build the configurations for each target savings, a Complexity Target Satisfaction algorithm was designed. This algorithm was able to reduce the optimization space by approximately 600 times, producing efficient configurations with up to 90% time savings. The complete system was implemented and tested against a state-of-the-art complexity management implementation. The results proved the efficiency of our solution, as it achieves more time savings and better compression for savings of 60% and higher.
