JPEG XS: </p> <ol><li><b><a href="/wiki/Transparency_(data_compression)" title="Transparency (data compression)">Visually transparent compression</a></b>: XS compressed content is indistinguishable from the original uncompressed content (passing ISO/IEC 29170-2 tests) for compression ratios between 2:1 and 10:1.</li> <li><b><a href="/wiki/Low_latency" class="mw-redirect" title="Low latency">Low latency</a></b>: The total end-to-end latency, introduced by the XS compression-decompression cycle, is minimal. Depending on the configuration, XS typically imposes only between 1 and 32 lines of additional end-to-end latency, when compared to the same system using uncompressed video.</li> <li><b>Lightweight</b>: XS is designed to have low computational and memory complexity, allowing for efficient low-power and low-resource implementations on various platforms such as <a href="/wiki/CPU" class="mw-redirect" title="CPU">CPU</a>, <a href="/wiki/GPU" class="mw-redirect" title="GPU">GPU</a>, <a href="/wiki/FPGA" class="mw-redirect" title="FPGA">FPGA</a> and <a href="/wiki/ASIC" class="mw-redirect" title="ASIC">ASIC</a>.</li></ol> <p>Relying on these key features, JPEG XS is suitable to be used in any application where uncompressed content is the norm, yet still allowing for significant savings in the required bandwidth usage, preserving quality and low latency. Among the targeted use cases are video transport over professional video links (like <a href="/wiki/Serial_digital_interface" title="Serial digital interface">SDI</a> and <a href="/wiki/Ethernet" title="Ethernet">Ethernet</a>/<a href="/wiki/Internet_Protocol" title="Internet Protocol">IP</a>), real-time video storage, memory buffers, omnidirectional video capture and rendering, and image sensor compression (for example in cameras and in the automotive industry).<sup id="cite_ref-10" class="reference"><a href="#cite_note-10"><span class="cite-bracket">[</span>10<span class="cite-bracket">]</span></a></sup> JPEG XS favors visually lossless quality in combination with low latency and low complexity, over crude compression performance. Hence, it is not a direct competitor to alternative image codecs like <a href="/wiki/JPEG_2000" title="JPEG 2000">JPEG 2000</a> and <a href="/wiki/JPEG_XL" title="JPEG XL">JPEG XL</a> or video codecs like <a href="/wiki/AV1" title="AV1">AV1</a>, <a href="/wiki/AVC/H.264" class="mw-redirect" title="AVC/H.264">AVC/H.264</a> and <a href="/wiki/High_Efficiency_Video_Coding" title="High Efficiency Video Coding">HEVC/H.265</a>. </p><p>Other important features are: </p> <ol><li><b>Exact bitrate allocation</b>: JPEG XS allows to accurately set the targeted bitrate to perfectly match the available bandwidth (also referred to as <a href="/wiki/Constant_bitrate" title="Constant bitrate">constant bitrate</a> or <a href="/wiki/Constant_bitrate" title="Constant bitrate">CBR</a>).</li> <li><b>Multi-generation robustness</b>: JPEG XS allows for at least 10 encoding-decoding cycles, without significant quality degradation.<sup id="cite_ref-11" class="reference"><a href="#cite_note-11"><span class="cite-bracket">[</span>11<span class="cite-bracket">]</span></a></sup> This feature allows for example transparently chaining of multiple devices that recompress the signal, without any significant quality degradation taking place.</li> <li><b>Multi-platform interoperability</b>: The algorithms used in JPEG XS allow for efficient implementations on different platforms, like CPU, GPU, FPGA and ASIC. Each of these platform architectures is best exploited when a specific degree of parallelism is available in the implementation. For instance, a multi-core CPU implementation will leverage a coarse-grained parallelism, while GPU or FPGA will work better with a fine-grained parallelism. Moreover, the choice of parallelism used in the implementation at the encoder will not affect that of the decoder. This means that real-time encoding and decoding between platforms is possible, without sacrificing the low complexity, low latency or high-quality properties.</li> <li><b>Support for mathematical <a href="/wiki/Lossless_compression" title="Lossless compression">lossless coding</a> (MLS)</b>: JPEG XS is also capable of coding images in a mathematically lossless way, to achieve perfect reconstruction at the decoder side (new profile supported by 2nd edition).</li> <li><b>Support for <a href="/wiki/High_Dynamic_Range" class="mw-redirect" title="High Dynamic Range">High Dynamic Range</a> (HDR) content</b>: The current version of JPEG XS supports bit-depths of up to 16 bits per component, and it provides several parameterizable non-linear transforms (NLTs) to efficiently compress HDR content.</li> <li><b>Support for RAW Bayer/CFA compression</b>: JPEG XS has also the capability to compress <a href="/wiki/Color_filter_array" title="Color filter array">Color Filter Array</a> (CFA) content, such as RAW <a href="/wiki/Bayer_filter" title="Bayer filter">Bayer</a> content produced by digital cameras.

Likewise, the capacities of video links and communication channels are also growing, yet at a slower pace than what is needed to address the huge video bandwidth growth. In addition, the investments to upgrade the capacity of links and channels are significant and need to be amortized over several years. </p><p>Moreover, both the broadcast and pro-AV markets are shifting towards AV-over-IP-based infrastructure, with a preference going to 1 Gigabit Ethernet links for remote production or 10G Ethernet networks for in-house facilities. Both 1G, 2.5G, and 10G Ethernet are cheap and ubiquitous, while 25G or better links are usually not yet affordable. Given the available bandwidth and infrastructure cost, relying on uncompressed video is therefore no longer an option, as 4K, 8K, increased bit depths (for HDR), and higher framerates need to be supported. </p><p>JPEG XS is a light-weight compression that visually preserves the quality compared to an uncompressed stream, at a low cost, targeted at compression ratios of up to 10:1. With XS, it is for example possible to repurpose existing SDI cables to transport 4K60 over a single 3G-SDI (at 4:1), and even over a single HD-SDI (at 8:1). Similar scenarios can be used to transport 8K60 content over various SDI cable types (e.g. 6G-SDI and 12G-SDI). Alternatively, XS enables transporting 4K60 content over 1G Ethernet and 8K60 over 5G or 10G Ethernet, which would be impossible without compression. The following table shows some expected compression ranges for some typical use cases. </p> <table class="wikitable" border="1" style="border-collapse: collapse;"> <tbody><tr> <th scope="col">Video stream</th> <th scope="col">Video throughput</th> <th scope="col">Link type</th> <th scope="col">Available throughput</th> <th scope="col">Compression ratio </th></tr> <tr> <td>2k 60 fps 4:2:2 10 bpc</td> <td>2.7 Gbit/s</td> <td>HD-SDI</td> <td>1.33 Gbit/s</td> <td>~2 </td></tr> <tr> <td>4k 60 fps 4:2:2 10 bpc</td> <td>10.6 Gbit/s</td> <td>3G-SDI</td> <td>2.65 Gbit/s</td> <td>~4 </td></tr> <tr> <td>2k 60 fps 4:2:2 10 bpc</td> <td>2.7 Gbit/s</td> <td>1G Ethernet</td> <td>0.85 Gbit/s</td> <td>~3 </td></tr> <tr> <td>2k 60 fps 4:4:4 12 bpc</td> <td>4.8 Gbit/s</td> <td>1G Ethernet</td> <td>0.85 Gbit/s</td> <td>~6 </td></tr> <tr> <td>4k 60 fps 4:4:4 12 bpc</td> <td>19.1 Gbit/s</td> <td>10G Ethernet</td> <td>7.96 Gbit/s</td> <td>~2.2 </td></tr> <tr> <td>8k 60 fps 4:2:2 10 bpc</td> <td>42.5 Gbit/s</td> <td>10G Ethernet</td> <td>7.96 Gbit/s</td> <td>~6 </td></tr> <tr> <td>8k 120 fps 4:2:2 10 bpc</td> <td>84.9 Gbit/s</td> <td>25G Ethernet</td> <td>21.25 Gbit/s</td> <td>~4 </td></tr></tbody></table> <div class="mw-heading mw-heading3"><h3 id="Real-time_video_storage_and_playout">Real-time video storage and playout</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=JPEG_XS&action=edit&section=4" title="Edit section: Real-time video storage and playout"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Related to the transport of video streams is the storage and retrieval of high-resolution streams where bandwidth limitations similarly apply.

Moreover, the demosaicing process can be power-hungry and will also introduce extra latency and complexity. The ability to push this step out of the camera is possible with JPEG XS and allows to use more advanced algorithms resulting in better quality in the end. </p> <div class="mw-heading mw-heading2"><h2 id="Standards">Standards</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=JPEG_XS&action=edit&section=6" title="Edit section: Standards"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-heading mw-heading3"><h3 id="JPEG_XS_(ISO/IEC_21122)"><span id="JPEG_XS_.28ISO.2FIEC_21122.29"></span>JPEG XS (ISO/IEC 21122)</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=JPEG_XS&action=edit&section=7" title="Edit section: JPEG XS (ISO/IEC 21122)"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The JPEG XS coding system is an ISO/IEC suite of standards that consists of the following parts: </p> <table class="wikitable" border="1" style="border-collapse: collapse;"> <tbody><tr> <th scope="col">Part</th> <th scope="col">1st edition</th> <th scope="col">2nd edition (in force) </th> <th>3rd edition</th> <th scope="col">Title </th></tr> <tr> <td>1</td> <td><a rel="nofollow" class="external text" href="https://www.iso.org/standard/74535.html">2019</a></td> <td><a rel="nofollow" class="external text" href="https://www.iso.org/standard/81551.html">2022</a> </td> <td><a rel="nofollow" class="external text" href="https://www.iso.org/standard/85247.html">2024</a></td> <td>Core coding system </td></tr> <tr> <td>2</td> <td><a rel="nofollow" class="external text" href="https://www.iso.org/standard/74536.html">2019</a></td> <td><a rel="nofollow" class="external text" href="https://www.iso.org/standard/81552.html">2022</a> </td> <td><a rel="nofollow" class="external text" href="https://www.iso.org/standard/85250.html">2024</a></td> <td>Profiles and buffer models </td></tr> <tr> <td>2</td> <td>-</td> <td><a rel="nofollow" class="external text" href="https://www.iso.org/standard/84584.html">2022/Amd1</a> </td> <td>-</td> <td>Profile and sublevel for 4:2:0 content </td></tr> <tr> <td>3</td> <td><a rel="nofollow" class="external text" href="https://www.iso.org/standard/74537.html">2019</a></td> <td><a rel="nofollow" class="external text" href="https://www.iso.org/standard/81553.html">2022</a> </td> <td><a rel="nofollow" class="external text" href="https://www.iso.org/standard/86420.html">2024</a></td> <td>Transport and container formats </td></tr> <tr> <td>4</td> <td><a rel="nofollow" class="external text" href="https://www.iso.org/standard/74538.html">2020</a></td> <td><a rel="nofollow" class="external text" href="https://www.iso.org/standard/82568.html">2022</a> </td> <td>in development</td> <td>Conformance testing </td></tr> <tr> <td>5</td> <td><a rel="nofollow" class="external text" href="https://www.iso.org/standard/74539.html">2020</a></td> <td><a rel="nofollow" class="external text" href="https://www.iso.org/standard/82569.html">2022</a> </td> <td>in development</td> <td>Reference software </td></tr></tbody></table> <p><b>Part 1</b>, formally designated as ISO/IEC 21122-1, describes the core coding system of JPEG XS. This standard defines the syntax and, similarly to other JPEG and MPEG image codecs, the decompression process to reconstruct a continuous-tone digital image from its encoded codestream. Part 1 does provide some guidelines of the inverse process that compresses a digital image into a compressed codestream, or more simply called the encoding process, but leaves implementation-specific optimizations and choices to the implementers. </p><p><b>Part 2</b> (ISO/IEC 21122-2) builds on top of Part 1 to segregate different applications and uses of JPEG XS into reduced coding tool subsets with tighter constraints. The definition of profiles, levels, and sublevels allows for reducing the complexity of implementations in particular application use cases, while also safeguarding interoperability. Recall that lower complexity typically means less power consumption, lower production costs, easier constraints, etc. Profiles represent interoperability subsets of the codestream syntax specified in Part 1. In addition, levels and sublevels provide limits to the maximum throughput in respectively the encoded (codestream) and the decoded (spatial and pixels) image domains. Part 2 furthermore also specifies a buffer model, consisting of a decoder model and a transmission channel model, to enable guaranteeing low latency requirements to a fraction of the frame size. </p><p><b>Part 3</b> (ISO/IEC 21122-3) specifies transport and container formats for JPEG XS codestreams. It defines the carriage of important metadata, like color spaces, mastering display metadata (MDM), and EXIF, to facilitate transport, editing, and presentation. Furthermore, this part defines the XS-specific ISOBMFF boxes, an Internet Media Type registration, and additional syntax to allow embedding XS in formats like MP4, MPEG-2 TS, or the HEIF image file format. </p><p><b>Part 4</b> (ISO/IEC 21122-4) is a supporting standard of JPEG XS that provides conformance testing and buffer model verification. This standard is crucial to implementers of XS and appliance conformance testing. </p><p>Finally, <b>Part 5</b> (ISO/IEC 21122-5) represents a reference software implementation (written in ISO C11) of the JPEG XS Part 1 decoder, conforming to the Part 2 profiles, levels and sublevels, as well as an exemplary encoder implementation. </p><p>A second edition of all five parts is in the making and will be published at the latest in the beginning of 2022. It provides additional coding tools, profiles and levels, and new reference software to add support for efficient compression of 4:2:0 content, RAW Bayer/CFA content, and mathematically lossless compression. </p> <div class="mw-heading mw-heading3"><h3 id="RFC9134_-_RTP_Payload_Format_for_ISO/IEC_21122_(JPEG_XS)"><span id="RFC9134_-_RTP_Payload_Format_for_ISO.2FIEC_21122_.28JPEG_XS.29"></span>RFC9134 - RTP Payload Format for ISO/IEC 21122 (JPEG XS)</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=JPEG_XS&action=edit&section=8" title="Edit section: RFC9134 - RTP Payload Format for ISO/IEC 21122 (JPEG XS)"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>RFC 9134<sup id="cite_ref-16" class="reference"><a href="#cite_note-16"><span class="cite-bracket">[</span>16<span class="cite-bracket">]</span></a></sup> describes a payload format for the <a href="/wiki/Real-time_Transport_Protocol" title="Real-time Transport Protocol">Real-Time Transport Protocol</a> (RTP, RFC 3550<sup id="cite_ref-17" class="reference"><a href="#cite_note-17"><span class="cite-bracket">[</span>17<span class="cite-bracket">]</span></a></sup>) to carry JPEG XS encoded video.

need to support in the decoded image domain (also called the spatial domain). The following table lists the levels as defined by JPEG XS. The maximums are given in the context of the sampling grid, so they refer to a per-pixel value where each pixel represents one or more component values. However, in the context of Bayer data JPEG XS internally interprets the Bayer pattern as an interleaved grid of four components. This means that the number of sampling grid points required to represent a Bayer image is four times smaller than the total number of Bayer sample points. Each group of 2x2 (four) Bayer values gets interpreted as one sampling grid point with four components. Thus sensor resolutions should be divided by four to calculate the respective width, height and amount of sampling grid points. For this reason, all levels also bear double names. Please refer to the standard for a complete specification of each level. </p> <table class="wikitable mw-collapsible mw-collapsed" border="1" style="border-collapse: collapse;"> <tbody><tr> <th scope="col">Level</th> <th scope="col">Max width</th> <th scope="col">Max height</th> <th scope="col">Max pixels (Lmax)</th> <th scope="col">Max pixel rate (Rs,max)</th> <th scope="col">Plev High Byte </th></tr> <tr> <td>Unrestricted</td> <td>65535</td> <td>65535</td> <td>-</td> <td>-</td> <td><code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">0x00</code> </td></tr> <tr> <td>1k-1, Bayer2k-1</td> <td>1280</td> <td>5120</td> <td>2621440</td> <td>83558400</td> <td><code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">0x04</code> </td></tr> <tr> <td>2k-1, Bayer4k-1</td> <td>2048</td> <td>8192</td> <td>4194304</td> <td>133693440</td> <td><code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">0x10</code> </td></tr> <tr> <td>4k-1, Bayer8k-1</td> <td>4096</td> <td>16384</td> <td>8912896</td> <td>267386880</td> <td><code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">0x20</code> </td></tr> <tr> <td>4k-2, Bayer8k-2</td> <td>4096</td> <td>16384</td> <td>16777216</td> <td>534773760</td> <td><code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">0x24</code> </td></tr> <tr> <td>4k-3, Bayer8k-3</td> <td>4096</td> <td>16384</td> <td>16777216</td> <td>1069547520</td> <td><code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">0x28</code> </td></tr> <tr> <td>8k-1, Bayer16k-1</td> <td>8192</td> <td>32768</td> <td>35651584</td> <td>1069547520</td> <td><code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">0x30</code> </td></tr> <tr> <td>8k-2, Bayer16k-2</td> <td>8192</td> <td>32768</td> <td>67108864</td> <td>2139095040</td> <td><code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">0x34</code> </td></tr> <tr> <td>8k-3, Bayer16k-3</td> <td>8192</td> <td>32768</td> <td>67108864</td> <td>4278190080</td> <td><code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">0x38</code> </td></tr> <tr> <td>10k-1, Bayer20k-1</td> <td>10240</td> <td>40960</td> <td>104857600</td> <td>3342336000</td> <td><code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">0x40</code> </td></tr></tbody></table> <p>Similarly to the concept of levels, JPEG XS defines sublevels to represent a lower bound on the required throughput that conforming decoders need to support in the encoded image domain.
