Video: Implementing standards-based Targeted Advertising on broadcast television


Last month, we featured DVB’s Targeted Advertising solution called DVB-TA. In that article, we saw the motivations to move to targeted advertising and how it was in use in Spain’s Artresmedia. Today’s video follows on from that introduction to DVB-TA with a range of speakers talking about implementation methods, interoperability and benefits to standardisation.

DVB’s Emily Dubs introduces the presenters starting with Nicolas Guyot from ENENSYS who speaks on the subject of the media value chain and TV’s reach. In Europe, the weekly reach of broadcast TV is still high at around 77% meaning the medium has still got strength. In terms of getting targeted ads on there, however, only a subset of devices can be used. In France, 36% of homes have a smart TV. Whilst this is a minority, it still equates to ten million TV sets. We hear about how France TV trialled targeted advertising for HbbTV where they collected consent and data which they used to segment people into four categories. The categories were finance, health, family and weather which they used to place ads in front of the viewer. With a view to scaling this out, the view was that standardisation was important to ensure ad placement was well understood by all equipment as well as measurement metrics.

 

 

Angelo Pettazzi from Mediaset makes a case next for standardisation. For Mediaset, moving to Targeted Advertising is a strategic move and mirrors the points made in the first video focusing on the need to keep TV advertising in line with what advertisers are looking for. In short, TA will maintain the relative value of their advertising slots. There are other benefits, however, such as more readily opening up advertising slots to local businesses and SMEs by providing availability of lower-cost slots.

Standards feature heavily for Mediaset. They have 4 million HbbTVs active monthly on their platform which simply wouldn’t have been possible without the HbbTV 2.0 standard in the first place. Using these devices they had previously tried a proprietary TA technology based on HTML5 but they found it didn’t always work well and the switching time could vary. They see the TA spec as a move towards more confidence in products along with the ability to substitute only single ads, a whole contiguous block or multiple substitutions in the same break.

Joe Winograd from Verance talks next about the use of Watermarking for targeted advertising. Advert timing and other signalling are usually carried separately to the media as SCTE-104, -25 or -224. However, there are times when a distribution chain is not yet compatible with this separate signalling. Linear advert substitution is usually done on the device, though, so by embedding this same signalling information within the audio and/or video feeds themselves, the receiving box is able to decode the embedded data and insert the ads as desired. Modifying video/audio data to carry messages is called watermarking and usually refers to the practice of marking a feed to uniquely identify it for the purposes of crime prevention. This method, however, is designed to carry dynamic data and is defined by the ATSC un their standards A/334, A/335 and A/336.

Pascal Jezequel from Harmonic speaks next about Dynamic Ad insertion interoperability. His main point is that if we’re to be inserting ads in a world of linear and OTT and streaming we should have one standard which covers them all. We need a detailed standard that allows precise, frame-accurate timing with smooth transitions. DVB-TA and HbbTV-TA initially focussed only on broadcast but is now being extended to cover streaming services provided over broadband. This interoperability will be a boost for operators and broadcasters.

Last in the video is Unified Streaming’s Rufael Mekuria who briefly explains the work that DVB is doing within the DBB-TA work but also within DVB-DASH. Having DVB involved helps with liaisons which is proving critical in ensuring that SCTE-35 is compatible with DVB-DASH. This work is in progress. Additionally, DVB is working with MPEG on CMAF and DVB is also liaising with DASH-IF.

The panel ends with a Q&A.

Video: Low Latency and High QOE for Live Streaming


Low latency streaming is always a compromise, but what can be done to keep QOE high?

This on-demand webinar looks at CMAF and presents some real-world data on this low latency technique. The webinar starts by explaining that CMAF is a low-latency streaming technology similar to HLS and other streaming protocols where the idea is to deliver the video as small files. Olivier and Alain from Harmonic explain how this is done and look at some of the trade-offs and compromises that are needed and introduce techniques to keep QOE high. They also look at deployment in cloud vs. on premise.

Pieter-Jan Speelmans talks about play tradeoffs and optimisations within the player. CMAF allows the buffer to be reduced and whilst a bad network may mean you buffer is similar to ‘normal’, but in good networks, this buffer can be brought down significantly. He also talks about how ABR switching is impacted by GOP length even in CMAF.

Viaccess-Orca explains how DRM works with CMAF and looks at some of the challenges including licences acquisition time and overloading licence servers at the beginning of events. Akamai’s Will Law explains some benefits of CMAF and the near-real-time of chunk-based transfer (HTTP 1.1) and how downloading chunks at full speed leads to problems when the same broadband link is used by several clients.

There are lots of good talks on CMAF, but this is one of the few which talks about CMAF not as theory, but as is deployable today.
