HEVC is a new video compression standard due for completion by JCT-VC in January 2013. It is the first significant development in video compression since H.264 was created a decade ago. Thanks to more sophisticated video processing and compression algorithms, HEVC is capable of delivering video of equivalent quality as ten-year-old predecessor H.264 while using only half the bitrate.HEVC is many times more complex than H.264 making implementation correspondingly much more difficult. Complexity is especially felt on the encoder side where an encoder has to decide between many more permutations of spatial subdivisions and multiple encoding modes. HEVC encoding remains a challenge to the industry. Offline, non-real-time encoding is possible albeit extremely slow. For some applications, notably broadcast and video conferencing, real-time and low-latency encoding is necessary and “brute-force”, supercomputing approaches are being used here.Parabola believes that it is possible to use a mix of innovative optimisation and algorithm approaches to implement HEVC encoding on commodity hardware whilst retaining or even beating HEVC's “50% bitrate” headline advantage. This aim of this project is to prove that it is possible to achieve an eventual goal of real-time, high definition encoding on contemporary consumer hardware without sacrificing the advantages of HEVC.The project will develop, evaluate, refine and demonstrate shortcut and heuristic algorithms that, when combined with conventional software optimization, realise the promise of HEVC on modest computers and devices.The key objectives of this project are:• to demonstrate feasibility of real-time software encoding on consumer hardware• to generate valuable intellectual property in the field of video compression• to augment Parabola’s existing HEVC technology to support fast encoding

HEVC是一种新的视频压缩标准，将于2013年1月由JCT-VC完成。这是自十年前H.264问世以来，视频压缩领域的第一个重大进展。由于更复杂的视频处理和压缩算法，HEVC能够提供与十年前的H.264同等质量的视频，而使用的比特率只有H.264的一半。HEVC比H.264复杂许多倍，因此实施起来也要困难得多。在编码端尤其感觉到复杂性，其中编码者必须在空间细分的更多排列和多种编码模式之间做出决定。HEVC编码仍然是该行业的一个挑战。离线、非实时编码是可能的，尽管速度非常慢。对于一些应用，特别是广播和视频会议，实时和低延迟的编码是必要的，这里正在使用“蛮力”的超级计算方法。Parbola相信，有可能使用创新的优化和算法方法的混合来在商用硬件上实现HEVC编码，同时保持甚至超过HEVC的“50%比特率”的整体优势。这个项目的目的是证明在不牺牲HEVC的优势的情况下，在当代消费者硬件上实现实时、高清晰度编码的最终目标是可能的。该项目将开发、评估、改进和演示快捷和启发式算法，这些算法与传统的软件优化相结合，在普通的计算机和设备上实现HEVC的前景。本项目的主要目标是：·在消费者硬件上展示实时软件编码的可行性·在视频压缩领域产生有价值的知识产权·增强Parbola的现有HEVC技术以支持快速编码
