The Next Big Windows Update Is Coming to Your Computer October 1. Optimize your storage and back up your files because the Windows Fall Update is just around the corner. At the IFA Keynote in Berlin Terry Meyerson, VP of the Windows and Devices group, announced that the Windows 1. Fall Creators Update would begin rolling out to compatible PCs October 1. This update will see the death of the old email program Outlook Express, as well as the depreciation of the popular Paint application. As Microsoft told Gizmodo back in July, while Paint won’t officially go away it will no longer be updated after this release, and many of it’s best features will be moved over to Paint 3. D, a new program developed by Microsoft intended to make producing 3. D artwork as easy as it’s been to produce the 2. D kind in Paint. Besides losing some old apps you might harbor nostalgia for, the Windows 1. Fall Creators Update will also improve One. Drive, so you can choose to only sync specific files and give the Windows Ink app the ability to mark up PDFs. Microsoft says there are other cool features coming in the update, including changes to its Photo app, and improved gaming integration for Windows and Xbox. Yet perhaps the biggest change coming with the Windows 1. Fall Creators Update is the rollout of Windows Mixed Reality. This is Microsoft’s long promised foray into consumer VR. While we’ve only seen a little of what this experience will look like we do know major computer makers like Dell, Acer, Lenovo, and HP are producing headset to work with Mixed Reality, and that unlike the Oculus Rift or HTC Vive, these headsets won’t require a bunch of extra cameras and IR sensors placed around the room to work properly. Headsets will start at $3. Acer and HP headsets, will come in bundles including controllers based on a design Microsoft announced back into May. We’ll definitely have a more exhaustive update on the Windows 1. Fall Creators Update and Windows Mixed Reality closer to the October 1. VP9 - Wikipedia. VP9 is an open and royalty free[1]video coding format developed by Google. VP9 is a successor to VP8 and competes mainly with MPEG's High Efficiency Video Coding (HEVC/H. At first, VP9 was mainly used on Google's popular video platform You. ![]() Tube.[2][3] The emergence of the Alliance for Open Media, and its support for the ongoing development of the successor AV1, led to growing interest in the format. In contrast to HEVC, VP9 support is common among web browsers (see HTML5 video § Browser support). The combination of VP9 video and Opus audio in the Web. M container, as served by You. Tube, is supported by roughly ¾ of the browser market (mobile included) as of early 2. VP9 support: the discontinued Internet Explorer (unlike its successor Edge) and Safari (both desktop and mobile versions) which remains the last H. Android has supported VP9 since version 4. Kit. Kat, though hardware acceleration varies. Parts of the format are covered by patents held by Google. The company grants free usage of its own related patents based on reciprocity, i. Features[edit]VP9 is customized for video resolutions greater than 1. UHD) and also enables lossless compression. The VP9 format supports the following color spaces: Rec. Rec. 7. 09, Rec. 2. SMPTE- 1. 70, SMPTE- 2. RGB.[7][8]VP9 supports HDR video using Hybrid Log- Gamma (HLG) and Perceptual Quantizer (PQ).[9][1. Efficiency[edit]An early comparison that took varying encoding speed into account showed x. SSIM.[1. 1]. Comparison of encoding artefacts. In a subjective quality comparison conducted in 2. HEVC (HM 1. 5. 0), MPEG- 4 AVC/H. JM 1. 8. 6), and VP9 (libvpx 1. VP9 support), VP9, like H. HEVC, while with synthetic imagery VP9 was close to HEVC.[1. By contrast, another subjective comparison from 2. HEVC and VP9 were tied at a 4. H. 2. 64.[1. 3]Netflix, after a large test in August 2. October the same year also found that tweaking encoding parameters could "reduce or even reverse gap between VP9 and HEVC".[1. At NAB 2. 01. 7, Netflix shared that they had switched to the EVE encoder, which had working two- pass rate control and was 8% more efficient than libvpx.[1. ![]() An offline encoder comparison between libvpx, two HEVC encoders and x. May 2. 01. 7 by Jan Ozer of Streaming Media Magazine, with encoding parameters supplied or reviewed by each encoder vendor (Google, Multicore. Ware and Main. Concept respectively), and using Netflix's VMAF objective metric, concluded that "VP9 and both HEVC codecs produce very similar performance" and "Particularly at lower bitrates, both HEVC codecs and VP9 deliver substantially better performance than H.

It was concluded that libvpx and x. H. 2. 64, but only at 1. Judged by the objective quality metric VQM in early 2. VP9 reference encoder delivered video quality on par with the best HEVC implementations.[1. A decoder comparison by the same developer showed 1. It also showed that the implementation can make a difference, concluding that "ffvp. Another decoder comparison indicated 1. CPU load than H. 2. Ittiam demo player was about 4. Chrome browser at playing VP9.[1. Profiles[edit]There are several variants of the VP9 format, the so- called coding profiles, that successively allow more features, starting from the basic version, the profile 0 (minimum for hardware implementations), up to profile 3: profile 0color depth: 8 bit/sample, chroma subsampling: 4: 2: 0profile 1color depth: 8 bit, chroma subsampling: 4: 2: 0, 4: 2: 2, 4: 4: 4profile 2color depth: 1. VP9 offers the following 1. Level. Luma Samples/s. Luma Picture Size. Max Bitrate (kbit/s)Max CPB Size for Visual Layer (kbits)Min Compression Ratio. Max Tiles. Min Alt- Ref Distance. Max Reference Frames. Examples for resolution @ frame rate. TBD8. 81. 04. 40. TBD8. 16. 10. 48. TBD8. 16. 10. 48. TBD8. 16. 10. 48. Technology[edit]. Example partitioning and internal coding order of a coding unit. Transform coefficients are scanned in a round pattern (increasing distance from the corner). This is to coincide (better than the traditional zig- zag pattern) with the expected order of importance of the coefficients, so to increase their compressibility by entropy coding. A skewed variant of the pattern is used when the horizontal or vertical edge is more important. VP9 is a traditional block- based transform coding format. The bitstream format is relatively simple compared to formats that offer similar bitrate efficiency like HEVC.[2. VP9 has many design improvements compared to VP8. Its biggest improvement is support for the use of coding units[2. This is especially useful with high- resolution video.[3][2. Also the prediction of motion vectors was improved.[2. In addition to VP8's four modes (average/"DC", "true motion", horizontal, vertical), VP9 supports six oblique directions for linear extrapolation of pixels in intra- frame prediction.[2. New coding tools also include: eighth- pixel precision for motion vectors,three different switchable 8- tap subpixel interpolation filters,improved selection of reference motion vectors,improved coding of offsets of motion vectors to their reference,improved entropy coding,improved and adapted (to new block sizes) loop filtering,the asymmetric discrete sine transform (ADST),larger discrete cosine transforms (DCT, 1. In order to enable some parallel processing of frames, video frames can be split along coding unit boundaries into up to four rows of 2. This is mandatory for video resolutions in excess of 4. A tile header contains the tile size in bytes so decoders can skip ahead and decode each tile row in a separate thread. The image is then divided into coding units called superblocks of 6. They can be subdivided either horizontally or vertically or both; square (sub)units can be subdivided recursively down to 4×4 pixel blocks. Subunits are coded in raster scan order: left to right, top to bottom. Starting from each key frame, decoders keep 8 frames buffered to be used as reference frames or to be shown later. Transmitted frames signal which buffer to overwrite and can optionally be decoded into one of the buffers without being shown. The encoder can send a minimal frame that just triggers one of the buffers to be displayed ("skip frame"). Each inter frame can reference up to three of the buffered frames for temporal prediction. Up to two of those reference frames can be used in each coding block to calculate a sample data prediction, using spatially displaced (motion compensation) content from a reference frame or an average of content from two reference frames ("compound prediction mode"). The (ideally small) remaining difference (delta encoding) from the computed prediction to the actual image content is transformed using a DCT or ADST (for edge blocks) and quantized. Something like a b- frame can be coded while preserving the original frame order in the bitstream using a structure named superframes. Hidden alternate reference frames can be packed together with an ordinary inter frame and a skip frame that triggers display of previous hidden altref content from its reference frame buffer right after the accompanying p- frame.[2. VP9 enables lossless encoding by transmitting at the lowest quantization level (q index 0) an additional 4×4- block encoded Walsh–Hadamard transformed (WHT) residue signal.[2. In container formats VP9 streams are marked with the Four. CCVP9. 0 (or in the future possibly VP9. VP0. 9.[3. 0] In order to be seekable, raw VP9 bitstreams have to be encapsulated in a container format, for example the Matroska- derived Web. M format (. webm) or the older minimalistic Indeo video file (IVF) format which is traditionally supported by libvpx.[2. Adoption[edit]Adobe Flash, which traditionally used VPx formats up to VP7, was never upgraded to VP8 or VP9, but instead to H. Therefore, VP9 often penetrated corresponding web applications only with the gradual shift from Flash to HTML5 technology, which was still somewhat immature when VP9 was introduced. Trends towards UHD resolutions, higher color depth and wider gamuts are driving a shift towards new, specialized video formats.
