JPEG XS in Drastic Software

dt logo 1.5inchJPEG XS (ISO/IEC 21122) is a wavelet-based image compression standard that provides high compression ratios, low latency, and high image quality. It is designed for applications that require low-latency transmission of high-quality images, such as professional video production, medical imaging, and remote sensing. It supports multiple image resolutions and color depths in a single stream, making it well-suited for adaptive streaming. JPEG XS has been adopted as the compression in broadcast and post for both TR-07/08, SMPTE 2110-22 and IPMX.

JPEG XS

Overview

JPEG XS (eXtended Specification) is an image compression standard that uses wavelet-based compression techniques to achieve high compression ratios while maintaining low latency and high image quality. It is designed to be used in applications that require low-latency transmission of high-quality images, such as professional video production, medical imaging, and remote sensing.

At a high level, JPEG XS works by dividing an image into small blocks called wavelets, which are analyzed and compressed independently. This allows for a more efficient use of bandwidth, since only the necessary information is transmitted. In addition, JPEG XS includes a number of features to minimize latency and maximize image quality, such as support for lossless compression and a low-complexity entropy coding algorithm.

One of the key advantages of JPEG XS is its ability to support multiple image resolutions and color depths in a single stream, which makes it ideal for applications that require adaptive streaming. Additionally, JPEG XS supports progressive transmission, which allows for the image to be displayed at increasingly higher quality as more data is received.

Overall, JPEG XS is a powerful image compression standard that offers a compelling combination of high compression ratios, low latency, and high image quality, making it a valuable tool for a wide range of applications.

JPEG XS has been adopted as the compression in broadcast and post for both TR-07/08, SMPTE 2110-22 and IPMX.

TR-07 

VSF's TR-07 (Television and Radio Industries Forum Technical Recommendation 07), is a technical specification that provides guidelines for the interchange of video, ancillary data and multichannel audio content between different production and post-production environments.

TR-07 using TCP or UDP transmission of MPEG-2 style transport stream encased in a RTP packetization structure to send JPEG XS video and, ST 302 PCM audio streams and ST 291-1 (using ST 2038) ancillary data streams.

One of the key features of TR-07 is its support for flexible configurations, allowing for the interchange of multichannel audio, video and ancillary data content between different systems and platforms. This is particularly important for applications such as broadcast and streaming, where consistent audio levels and characteristics are critical for a good viewer experience.

Overall, TR-07 is a valuable technical resource for anyone involved in the production or delivery of multichannel audio content in the television and radio industries, providing a standardized approach to handling and managing complex audio signals across different systems and platforms.

SMPTE 2110-22

SMPTE 2110-22 is a technical standard developed by the Society of Motion Picture and Television Engineers (SMPTE) that specifies the transport of audio and video content over IP networks. Specifically, SMPTE 2110-22 defines a standardized approach to transporting compressed video signals using the JPEG XS codec.

At a technical level, SMPTE 2110-22 defines a set of protocols and specifications for the encapsulation and transport of JPEG XS-compressed video signals over IP networks. This includes the use of standard transport protocols such as RTP (Real-Time Transport Protocol) and FEC (Forward Error Correction) to ensure reliable and efficient transmission of video data, as well as standardized metadata formats to ensure interoperability between different systems and devices.

The use of JPEG 2000 as a compression standard within SMPTE 2110-22 is particularly significant, as it enables the transmission of high-quality, visually lossless video signals at low bit rates. This is achieved through the use of advanced wavelet-based compression techniques, which are able to compress video data more efficiently than traditional methods such as MPEG or H.264.

In addition to the transport of video signals, SMPTE 2110-22 also includes specifications for the transport of audio signals using standard audio-over-IP protocols such as AES67. This enables audio and video signals to be transported together within the same IP stream, allowing for synchronized playback and accurate lip-sync between audio and video.

Overall, SMPTE 2110-22 represents a powerful solution for the transport of high-quality video and audio content over IP networks, offering a standardized approach to the transport and processing of media signals that enables interoperability between different systems and devices.

IPMX

IPMX (Internet Protocol Media Experience) is a set of open standards and specifications developed by the Alliance for IP Media Solutions (AIMS) to enable the transport of professional media over IP networks. One of the key components of IPMX is the use of the JPEG XS (eXtended Specification) compression standard for video, which allows for high-quality, low-latency video transmission over IP networks.

At a technical level, IPMX defines a set of standardized components and protocols for the transmission, routing, and processing of media signals over IP networks. These include standards for video, audio, and data encapsulation, as well as protocols for discovery, registration, and control of networked media devices.

The use of JPEG XS as a compression standard for video within the IPMX framework is particularly significant, as it allows for the transmission of high-quality, visually lossless video signals at low latency, even over low-bandwidth networks. This is achieved through the use of wavelet-based compression techniques, which are able to compress video data more efficiently than traditional methods such as MPEG or H.264.

In addition to supporting JPEG XS for video, IPMX also includes support for other industry-standard codecs for audio and data, as well as support for standard transport protocols such as RTP and SMPTE ST 2110. This allows for a high degree of flexibility and interoperability within the IPMX ecosystem, enabling media signals to be easily exchanged between different devices and systems.

Overall, the combination of IPMX and JPEG XS represents a powerful solution for the transport of professional media over IP networks, offering high-quality, low-latency video transmission along with a robust set of standardized protocols and specifications for the transmission, routing, and processing of media signals.
