Video: JPEG-XS and ST 2110

Posted on 11th June 2019 by Adam K

JPEG XS is a brand-new, ultra-low latency standard delivering JPEG 2000 quality with 1000x lower latency; microseconds instead of milliseconds. This mezzanine compression standard promises compression ratios of up to 10:1, resolutions of up to 8K plus HDR and features frame rates from 24 to 120 fps.

Jean-Baptiste Lorent from intoPIX shows how JPEG-XS can be used with SMPTE ST-2110 stack. Part -22 of ST 2110 allows for transport of compressed video essence as an alternative to uncompressed essence – all the other elementary streams stay the same, just the video RTP payload changes. This approach saves a lot of bandwidth and keeps all the existing advantages of moving from SDI to IP at the same time.

Based on TICO which arrived in products four or more years ago allowing HD products to support UHD workflows, JPEG XS was also designed for visually lossless quality and maintaining that quality over multiple re-encoding stages. The combination of very-low microsecond-latency and relatively low bandwidth makes it ideal for remote production of live events.

Webinar: Tools for DASH Streaming

Posted on 10th June 2019 by Russell Trafford-Jones

MPEG DASH is a standardised, widely-supported protocol for networked streaming – but how can you spot problems and tell if you or another vendor have implemented it right?

This webinar, run by HbbTV – an initiative aimed at merging over-the-air broadcast with broadband delivery (which includes both file-download and streaming) – sets out to explain how you can test your DASH streaming using new tools now available. For instance, HbbTV and DVB have collaborated on a DASH validation tool which checks MPDs, segments and more to be sure that a stream is compliant with both DVB and HbbTV specifications.

Bringing together the experience of Bob Campbell from Eurofins, Waqar Zia from Nomor Research and Juha Joki from Sofia Digital, anyone who develops for, or provides services based on DASH will benefit from this webinar.

Date: 18th June 2019, 16:00 BST / 17:00 CEST

Video: The (Live) Streaming Pro’s Toolbox

Posted on 7th June 2019 by Russell Trafford-Jones

Everyone has a go-to program or three they use for problem solving. Here is a review of a whole swathe of diagnosis programs out there for live streaming.

There are known favourites like Wireshark, FFPlay and MediaInfo, free applications such as Eyevinn Technology’s Segment Analyser and the open source YUView. And this also covers paid programs like Elecard’s Stream Analyser and Telestream Switch.

This talk by David Hassoun CEO of RealEyes media is well worth a look because there is bound to be something there you didn’t know about – and who knows how useful that will be to you!

Video: Analysis of emerging video codecs: coding tools, compression efficiency and complexity

Posted on 6th June 2019 by Russell Trafford-Jones

There continues to be fervent activity in codec development and it’s widely expected that there won’t be a single successor to AVC (h.264). Vying for one of the spots is AV1 but also MPEG’s VVC.

In this talk at SMPTE 2018, Julien Le Tanou from MediaKind compares the coding tools used by VVC and AV1 and explains the methodology he uses to compare the two codecs. We see the increase in decoding time compared to HEVC required for VVC as well as the famously slow AV1. We also see the bitrate savings with VVC performing better.

Julien also presents subjective results which are not correlated to the objective results and explains reasons for this.
