Moreover, implementation guidelines inform about how to achieve low latency implementations. This allows deriving the hardware and software requirements for different purposes such as high compression ratios, low memory or low logic implementations. JPEG XS Part 2 (ISO/IEC 21122-2) 2nd edition ensures interoperability between different implementations by specifying typical codestream parameterizations and properties. Moreover, it informatively explains the key algorithms enabling an encoder to generate a JPEG XS codestream. JPEG XS Part 1 (ISO/IEC 21122-1) 2nd edition normatively defines how a compressed JPEG XS codestream can be transformed into a decoded image in a bit exact manner. JPEG XS is a multi-part specification including the following parts: Part 1: Core coding system More detailed information is available in the whitepaper on JPEG XS. ![]() By these means, systems can offer increased resolutions and frame rates while retaining visually lossless quality. for the Automotive Industry and for high-end professional photography. This includes, among others, professional video links (3G/6G/12G-SDI), IP transport (SMPTE 2022-5/6 & SMPTE 2110), real-time video storage, memory buffers, omni-directional video capture system, head-mounted displays for Virtual or Augmented Reality and image sensor compression – i.e. The standard also offers lossless compression of image data with a precision of up to 12-bits per component.Īll of these properties allow JPEG XS to be applied in applications which transported uncompressed image data before. Gigabit Ethernet, and it offers an end-to-end delay equal to a fraction of a frame. Moreover, the codec allows for a very precise bit-rate control to accurately match the available bandwidth, e.g. It supports various pixel formats, including raw Bayer, classic RGB and the typical YUV representations, all up to 16 bits per component. ![]() Typical compression ratios are up to 10:1 for 4:4:4, 4:2:2, and 4:2:0 images but can also be higher depending on the nature of the image or the requirements of the targeted application. In addition, JPEG XS excels with high multi-generation robustness and is particularly optimized for visual lossless compression as defined in ISO/IEC 29170-2 for both natural and synthetic images. Its design offers various degrees of parallelism allowing for efficient implementation on various platforms such as FPGAs, ASICs, CPUs and GPUs. For example, this allows hardware implementations that do not require external memory. The JPEG XS (ISO/IEC 21122) standard specifies a compression technology with an end-to-end latency of a few lines, at a low implementation complexity.
