Problems on Video Coding
Problems on Video Coding Guan-Ju Peng Graduate Institute of Electronics Engineering, National Taiwan University 1 Problem 1 How to display digital video designed for TV industry on a computer screen with best quality? .. Hint: computer display is 4:3, 1280x1024, 72 Hz, pro- gressive. Supposing the digital TV display is 4:3 640x480, 30Hz, Interlaced. The problem becomes how to convert the video signal from 4:3 640x480, 60Hz, Interlaced to 4:3, 1280x1024, 72 Hz, progressive. First, we convert the video stream from interlaced video to progressive signal by a suitable de-interlacing algorithm. Thus, we introduce the de-interlacing algorithms ¯rst in the following. 1.1 De-Interlacing Generally speaking, there are three kinds of methods to perform de-interlacing. 1.1.1 Field Combination Deinterlacing ² Weaving is done by adding consecutive ¯elds together. This is ¯ne when the image hasn't changed between ¯elds, but any change will result in artifacts known as "combing", when the pixels in one frame do not line up with the pixels in the other, forming a jagged edge. This technique retains full vertical resolution at the expense of half the temporal resolution. ² Blending is done by blending, or averaging consecutive ¯elds to be displayed as one frame. Combing is avoided because both of the images are on top of each other. This instead leaves an artifact known as ghosting. The image loses vertical resolution and 1 temporal resolution. This is often combined with a vertical resize so that the output has no numerical loss in vertical resolution. The problem with this is that there is a quality loss, because the image has been downsized then upsized. -

NVIDIA Hardware Video Encoder 1.1. Introduction NVIDIA GPUs - beginning with the Kepler generation - contain a hardware-based encoder (referred to as NVENC in this document) which provides fully accelerated hardware-based video encoding and is independent of graphics/CUDA cores. With end-to-end encoding offloaded to NVENC, the graphics/CUDA cores and the CPU cores are free for other operations. For example, in a game recording scenario, -
Viarte Remastering of SD to HD/UHD & HDR Guide
Page 1/3 Viarte SDR-to-HDR Up-conversion & Digital Remastering of SD/HD to HD/UHD Services 1. Introduction As trends move rapidly towards online content distribution and bigger and brighter progressive UHD/HDR displays, the need for high quality remastering of SD/HD and SDR to HDR up-conversion of valuable SD/HD/UHD assets becomes more relevant than ever. Various technical issues inherited in legacy content hinder the immersive viewing experience one might expect from these new HDR display technologies. In particular, interlaced content need to be properly deinterlaced, and frame rate converted in order to accommodate OTT or Blu-ray re-distribution. Equally important, film grain or various noise conditions need to be addressed, so as to avoid noise being further magnified during edge-enhanced upscaling, and to avoid further perturbing any future SDR to HDR up-conversion. Film grain should no longer be regarded as an aesthetic enhancement, but rather as a costly nuisance, as it not only degrades the viewing experience, especially on brighter HDR displays, but also significantly increases HEVC/H.264 compressed bit-rates, thereby increases online distribution and storage costs. 2. Digital Remastering and SDR to HDR Up-Conversion Process There are several steps required for a high quality SD/HD to HD/UHD remastering project. The very first step may be tape scan. The digital master forms the baseline for all further quality assessment. isovideo's SD/HD to HD/UHD digital remastering services use our proprietary, state-of-the-art award- winning Viarte technology. Viarte's proprietary motion processing technology is the best available. -

Interlacing is a widely used be broadcast. Transmission of interlaced videos was widely technique, for television broadcast and video recording, to popular in various television broadcasting systems such as double the perceived frame rate without increasing the NTSC [2], PAL [3], SECAM. Many broadcasting agencies bandwidth. But it presents annoying visual artifacts, such as made huge profits with interlaced videos. Video acquiring flickering and silhouette "serration," during the playback. systems on many occasions naturally acquire interlaced video Existing state-of-the-art deinterlacing methods either ignore and since this also proved be an efficient way, the popularity the temporal information to provide real-time performance of interlaced videos escalated. but lower visual quality, or estimate the motion for better deinterlacing but with a trade-off of higher computational cost. The question `to interlace or not to interlace' divides the TV and the PC communities. A proper answer requires a common understanding of what is possible nowadays in deinterlacing video signals. This paper outlines the most relevant methods, and provides a relative comparison. -
