intoPIX to Demo JPEG XS Live 4K-over-IP Streaming at SMPTE 2018
intoPIX is presenting a full JPEG XS standard preview at the SMPTE 2018 Annual Technical Conference & Exhibition coming to Los Angeles from 22 to 25 October. The coding specialists at intoPIX are demonstrating a first TICO-XS hardware implementation of the upcoming JPEG XS standard in a complete low-latency, live 4K streaming-over-IP application with real-time playout.
On a separate screen, intoPIX will organise a 'lossless quality' comparison. Visitors will be able to judge the codec’s quality on a split-screen playback, displaying various videos in a side by side uncompressed / compressed mode with varying compression ratios down to 10:1 compression.
Compressed Future
Sparking interest in compression systems like TICO-XS are increasing resolutions of 4K or 8K, higher frame rates, 360° capture and higher quality pixels associated with HDR. Modern devices and infrastructures need to handle growing data volumes. The JPEG-XS mezzanine codec standard can be applied wherever uncompressed video is currently used – VR, games, live production and digital cinema. To support transportation of UHDTV streams across the IP network or the existing 3G-SDI infrastructure, a new smart, fast and light compression is needed.
TICO may also help broadcasters take advantage of an integrated and UHD ecosystem from beginning to end. Achieving a visually lossless compression from 4:1, TICO enables the mapping of a single 4K/UHD 2160p60 stream over a single 3G-SDI link. Over 10Gbps Ethernet, it allows simultaneous transmission of up to three streams of 2160p60. 10 GB Ethernet or 3G-SDI networks are widely deployed and operated cost effectively within broadcast environments. Furthermore, using the RTP (Real-time Transport Protocol) mapping of TICO, most any video format can be transported over most networks.
Under Standardisation
Currently under standardisation as JPEG XS by the JPEG committee, TICO-XS codec is suitable for IP workflows in studio environments, local video networks and VR/AR applications. Built on the intoPIX TICO system, it allows straightforward integration in all existing hardware or software systems due to the high granularity of parallelism in the algorithm – that is, individual tasks are relatively small in terms of code size and execution time.
It also makes an alternative to supporting expensive uncompressed video networks. The JPEG XS standard enables the use of standard COTS Ethernet infrastructures or other wired connections to set up uncomplicated, cost-effective IP transmission.
Set to take advantage of the SMPTE ST 2110 transport layer system over IP, it brings further bandwidth efficiency for flows in HD, 4K and 8K with microsecond latency, lossless quality, and bandwidth usage typical for most types of production workflow: ranging from 125Mbps to 400Mbps for HD, and from 500Mbps to 1.6Gps for 4K. www.intopix.com
