JPEG XS (ISO/IEC 21122) is a direct replacement for uncompressed video workflows and introduces significant network bandwidth and media processing savings to production facilities and wide-area networks (WANs). This contemporary and widely-implemented video codec achieves visually lossless image quality at microsecond-level latency. JPEG XS scales effortlessly for SDI or IP format video and is an obvious choice for HD, UHD-4K and UHD-8K content production over the wide-area network. An efficient power and processing footprint makes further makes JPEG XS highly suited for bandwidth-efficient campus and facility networks (LANs).
The suite of standardization work around JPEG XS, in particular VSF TR-07, is of particular importance when there is a lack of control over PTP time accuracy. The combination of JPEG XS and VSF TR-07 allows for production networks to effortlessly extend over the WAN without PTP Time Error performance.
As JPEG XS processing can be implemented in general purpose compute, i.e. CPU as well as special purpose compute such as GPU and FPGA, there is already an established ecosystem of scalable JPEG XS processing applications with ready-made essence, composite and aggregate standard exchange formats, i.e. VSF TR-08, TR-07 and TR-09 respectively.
The ability of JPEG XS to operate and be exchanged across LAN, WAN and Cloud, whether that is PTP-timed or Transport Streams adapted makes it a breakthrough in flexibility for video compression standards. This orchestration or new technologies and operational insights is fundamental to efficiently delivering video with no delay or quality compromise. In essence, JPEG XS allows production networks and remotely produced events to do ten times more with existing resources.
For latency-critical applications such as remote production and contribution the industry’s choice is JPEG 2000 (J2K). A robust and mature standard deployed by professional broadcast service providers, J2K delivers world class quality-to-bandwidth ratio.
The coding system uses intra-frame compression techniques based on wavelet technology and offers an extremely high level of scalability, accessibility and interoperability with third party equipment.
Visually lossless SD, HD and UHD JPEG 2000 encoding and decoding reduces bandwidth usage by 90% compared to uncompressed transport. Audio and ancillary data transparency combined with TR-01 compliance allows the compression scheme to be used in any type of workflow and multi-vendor deployments.
The Net Insight Nimbra implementation of JPEG 2000, combined with our advanced protection mechanisms, enables broadcasters to use cost-efficient IP links for the real-time transport of professional media.
J2K is perfectly suitable for live video, including fast moving sports content. With low bandwidth utilization, combined with high quality and availability, it can fit easily into a cost-effective managed IP transport available anywhere in the world.
H.264, also known as MPEG-4 AVC (Advanced Video Coding), is the most world’s widely used video compression standard for HD content with billions of devices capable of supporting it.
Production or distribution quality SD and HD MPEG AVC H.264 encoding and video decoding delivers optimal image quality, reduced bandwidth usage and maximum workflow interoperability. Net Insight’s implementation offers 4:2:0 8-bit support and flexible parallel encoding and video decoding capability in combination with industry-leading internet transport reliability.
lthough standardized as far back as 2003, its forward-looking design, has seen MPEG-4 H.264 become the preferred compression standard for streaming video services. Compliance with SMPTE ST 2022-2 allows for IP interoperable content exchange and multi-vendor deployments.
MPEG-4 is ideal for all bandwidth-efficient high-quality video workflows.
Net Insight incorporates advanced video encoding in the heart of both the Aperi and the Nimbra platforms. The encoding schemes used are JPEG2000, H.264/MPEG-4, JPEG XS, and H.265/HEVC. Any of these options can be handled by Net Insight giving productions the flexibility needed to cater for any scenario.
Both platforms also support uncompressed transport including 1080p and 4K. Net Insight focuses on open standards as SMPTE 2110 for interoperability reasons. This also means that it is possible to combine uncompressed/light compression with other compression formats in the same system to allow for more advanced and potentially more cost-efficient workflows interconnecting production processing sites.
World’s largest alliance of public service media organisation
Since 2004, when the EBU selected Net Insight’s Nimbra platform, the EUROVISION Fibre Network (FiNE) has evolved with Net Insight’s latest products and features.
The EUROVISION satellite and fibre network is one of the largest and most rock solid in the world. It delivers more than 80,000 hours of programming every year, the majority of which is live sports. Its undisputed reputation for flexibility and reliability is reflected in the prestigious events it regularly carries on the EUROVISION network.
WHITE PAPER
As cloud production becomes an integral part of broadcasters’ live workflows, the corresponding cloud infrastructure becomes an integral part of the media transport network.
