Webinar: Video Ad Optimisation

Posted on 22nd October 2019 by Russell Trafford-Jones

Date: 24th October, 2019 Time: 10am PST / 1pm EDT / 18:00 GMT

If there’s one thing that’s been clear throughout all the years of streaming video on the internet, it’s that if the viewer doesn’t have a good time, it’s literally a big turn-off. If you’re going to show ads, show them well otherwise it can make for a terrible experience. Problems with ads undermine trust in an otherwise great service.

This is the topic under the spotlight in this webinar from the Streaming Video Alliance which brings together CommScope (previously ARRIS), IAB Tech Labs, Adobe and Conviva to discuss the best practices for getting ads right examining how to deliver them and ways to insert them.

Video: What’s New in NMOS? – A Tutorial on the Latest in Video over IP Control and Security

Posted on 21st October 2019 by Adam K

The Networked Media Open Specifications (NMOS) have been developed to provide a control and management layer along side the SMPTE ST 2110 transport layer. The idea behind NMOS was to deliver an open specification to provide the software layers that abstract a lot of complexities of ST 2110 and make it easy to interface with any control system.

The NMOS family of specifications began with projects for Discovery & Registration, Device Connection Management and Network Control, but has grown to include many other important subjects such as Event & Tally, Audio Channel Mapping and Interoperable Security.

In this video, Jed Deame discusses the latest advancements including IS-08, IS-09, BCP-002, BCP-003 and IS-10. These additions allows NMOS to surpass the level of control provided in SDI while also adding a layer of security.

The following Interface Specifications and Best Current Practices are presented:

IS-04 (Registration and Discovery) – new features: support for GPI over Ethernet (IS-07) and authorisation signalling for security layers BCP-003-02
IS-05 (Connection Management) – new features: MQ Telemetry Transport and WebSocket Transport, support for supplementary externally defined parameters
IS-08 (Audio Mapping) – audio routing / shuffling facility
IS-09 (System Resources) – System ID, server priority, security with HTTPS support, advertisement of system resources such as RDS (Registration and Discovery Server)
BCP-002 (Grouping) – uses tag resources in IS-04 in order to achieve a natural groups of senders and receivers (e.g. to tie audio, video and metadata)
BCP-003-01 (Security) – uses Transport Layer Security (TLS) in order to encrypt communications between API servers and their clients
BCP-003-02 (Security) – covers client authorization for the NMOS APIs
IS-10 (Authorisation API) – accompanies the BCP-003-02 specification to restrict what users are authorized to change in an NMOS system (core technologies: PKI, HTTPS, REST, JSON, Oauth 2.0 and JWT)

The presentation finishes with the customer case study – secure KVM all over an IP network.

Webinar: Creating brand loyalty and new TV revenues with next-generation voice control

Posted on 18th October 2019 by Russell Trafford-Jones

With smart speakers, mobile phones and computers all sporting voice-controlled interfaces, it’s no surprise that smart TVs, Apple TVs and others can be voice controlled. This webinar looks at how much consumers expect control and what they expect.

Getting voice right, can be a really big differentiator in terms of enjoyment and confidence of a service and the speakers discuss how that can enhance retention and growth.

As seen with a recent update to Apple’s HomePod which allows it to recognise who’s speaking, voice can be used for personalisation, security and privacy when carefully applied to the service.

The webinar will also discuss fraud reduction and ecommerce opportunities.

Video: DASH Updates

Posted on 17th October 2019 by Russell Trafford-Jones

MPEG DASH is a standardised method for encapsulating media for streaming similar to Apple’s HLS. Based on TCP, MPEG DASH is a widely compatible way of streaming video and other media over the internet.

MPEG DASH is now on its 3rd edition, its first standard being in 2011. So this talk starts by explaining what’s new as of July 2019 in this edition. Furthermore, there are amendments already worked on which are soon to add more features.

Iraj Sodagar explains Service Descriptors which will be coming that allow the server to encapsulate metadata for the player which describes how the publisher intended to show the media. Maximum and minimum latency and quality is specified. for instance. The talk explains how these are used and why they are useful.

Another powerful metadata feature is the Initialization Set, Group and Presentation which gives the decoder a ‘heads up’ on what the next media will need in terms of playback. This allows the player to politely decline to play the media if it can’t display it. For instance, if a decoder doesn’t supply AV1, this can be identified before needing to attempt a decode or download a chunk.

Iraj then explains what will be in the 4th edition including the above, signalling leap seconds and much more. This should be published over the next few months.

Amendement 1 is working towards a more accurate timing model of events and defining a specific DASH profile for CMAF (the low-latency streaming technology based on DASH) which Iraj explains in detail.

Finishing off with session based DASH operations, a look over the DASH workplan/roadmap, ad insertion, event and timed metadata processing, this is a great, detailed look at the DASH of today and of 2020.
