Video: Get Ready For A Multiple Codec World

Posted on by Russell Trafford-Jones

The codec world is fragmenting. None of the new entrants on to the market is expected to ever gain the universal status that AVC enjoys. This panel from Streaming Media East takes a look at how to prepare for this.

The panel kicks off discussing the differences between AVC and HEVC, VP9 and AV1 and moves on to discuss the pros and cons of supporting multiple codecs. Tarek from Twitch explains its partial adoption of VP9 – the reasons that it makes sense but the overheads which it brings the business.

Vittorio Giovara from Vimeo explains their reasons for using HEVC including their drive to be able to encode and deliver 10-bit video. Ellation’s Subhrendu Sarakar makes the point that managing codec changes and bitrate changes needs to be done carefully to ensure viewers that notice the change understand them and don’t feel there has been a reduction of quality.

After a brief discussion of encoding strongly characterised video types such as anime and gaming, the conversation moves on to AV1 and migrating from VP9 and there is an audience question on HEVC licensing and the lack of use of SVC (Scalable Video Coding)

It’s now relatively well known that Twitch deployed VP9 using FPGAs rather than as a software encoder which was the only way to get the real-time speed at 1080p60. The panel discusses encoding speed both in the encoder and decoder for VP9 and AV1 then finishes with a Q&A from the audience.

Video: TR-1001 Replacing Video By Spreadsheet

Posted on by Russell Trafford-Jones

Here to kill the idea of SDNs – Spreadsheet Defined Networks – is TR-1001 which defines ways to implement IP-based media facilities avoiding some typical mistakes and easing the support burden.

From the JT-NM (Joint Taskforce – Networked Media), TR-1001 promises to be a very useful document for companies implementing ST-2110 or any video-over-IP network Explaining what’s in it is EEG’s Bill McLaughlin at the VSF’s IP Showcase at NAB.

This isn’t the first time we’ve written about TR-1001 at The Broadcast Knowledge. Previously, Imagine’s John Mailhot has dived in deep as part of a SMPTE standards webcast. Here, Bill takes a lighter approach to get over the main aims of the document and adds details about recent testing which happened across several vendors.

Bill looks at the typical issues that people find when initially implementing a system with ST-2110 devices and summarises the ways in which TR-1001 mitigates these problems. The aim here is to enable, at least in theory, many nodes to be configured in an automatic and self-documenting way.

Bill explains that TR-1001 covers timing, discovery and connection of devices plus some of configuration and monitoring. As we would expect, ST-2110 itself defines the media transport and also some of the timing. Work is still to be done to help TR-1001 address security aspects.

Webinar: Building Tomorrow’s OTT Platforms

Posted on by Russell Trafford-Jones

Discover the critical success factors the Broadcasters and platform owners, investing millions in building and upgrading OTT platforms, need to achieve to ensure they can compete successfully with a growing array of digital competitors and deliver compelling user experiences.

Many of these broadcasters are beginning to move from their initial OTT offerings to more mature services that can scale for the future, and answer the requirements of demanding viewers and regulators.

This webinar uncovers the essential parts of a flourishing OTT service, including:
– Delivering content at scale as more viewing and live events move to OTT
– Ensuring a class-leading user experience and quality
– Using analytics to maximise revenue and engagement
– Ensuring cost efficiency in the OTT workflow
– Securing platforms and content against piracy and malicious attacks

Video: Deploying WebRTC In A Low-Latency Streaming Service

Posted on by Russell Trafford-Jones

WebRTC is an under appreciated streaming protocol with sub-second latency. Several startups are working hard to harness this technology born by Google for use in video conferencing for live streaming.

When you look at the promised latencies, you can see why. CMAF, the lowest-latency protocol for live streaming using HLS-style chunked file delivery is gaining wider adoption and provides a very impressive latency reduction, however it typically stops at between 4 and 2 seconds. To get below a second, WebRTC is almost the only option out there.

In this talk, Millicast CTO Dr. Alex Gouaillard looks at the misunderstandings and misinformation are out there regarding WebRTC. Dr. Alex covers WebRTC now having ABR, using over multiple hops, the testing ecosystem and much more.

Dr. Alex also covers the lessons learnt over the last two years of development and implementation of the standard and finishes by looking to the future which will bring in QUIC, AV1 and Web ASM.
