This document provides a review of loudness specifications and regulations, as well as an overview of advanced loudness topics. It discusses why loudness measurement is important, specifications like BS.1770-2, and how gating reflects loudness perception. It also covers changes to international regulations, network certification, and international carriage considerations. The document concludes with an overview of Volicon's loudness monitoring solutions and a Q&A section.
Measuring Loudness Levels § When we measure loudness levels, we need to account for frequency sensitivity § This is done by applying a weighting filter to audio § For several yeas the A-weighting filter was commonly used § Other weighting curves (B and C for example) are also defined § Additionally measurement with multi channel audio need to take how we hear audio from different directional sources (i.e. surrounds) into account.
Loudness Management Strategies
§ “Measure and Set” § Measure content, set content with accurate metadata § “Measure and Scale” § Measure content, scale content to desired target level § “Target and Evaluate” § Select target loudness for submission – Specified in technical delivery specs § Evaluate content for compliance

Replacing a crossbar switch with ‘virtual’ IP packet switching - The ability to expand video-over-IP systems ‘one piece at a time’ and the decentralized nature of the matrix makes the technology very compelling for any size or scope of AV project.. AV-over-IP is the transport of AV signals over a standard Ethernet network, including…
HD Video (e.g. HDMI, DVI)
Audio
Control Signals (e.g. IR)
Peripheral Signals (e.g. USB)
Does Dante require special switches? No. We strongly recommend that Gigabit switches be used due to the clear advantages in performance and scalability.
Does Dante require a dedicated network infrastructure? No, a dedicated network infrastructure is not required. Dante-enabled devices can happily coexist with other equipment making use of the network, such as general purpose PCs sending and receiving email and other data.
Does Dante require any special network infrastructure? No, special network infrastructure is not required. Since Dante is based upon universally accepted networking standards, Dante-enabled devices can be connected using inexpensive off-the-shelf Ethernet switches and cabling.
What features are important when purchasing a switch? Dante makes use of standard Voice over IP (VoIP) Quality of Service (QoS) switch features, to prioritize clock sync and audio traffic over other network traffic. VoIP QoS features are available in a variety of inexpensive and enterprise Ethernet switches. Any switches with the following features should be appropriate for use with Dante:
Gigabit ports for inter-switch connections
Quality of Service (QoS) with 4 queues
Diffserv (DSCP) QoS, with strict priority
Totally new to AV over IT? This may help. If you have worked with any of the popular protocols, your time is better spent in other sessions. AV over IT methods vary in application of OSI model. Audio Networking - One RJ45 and CAT5 cable for dozens of signal paths. Switches can provide hardware time stamping which allows synchronization, offsets, and corrections. All covered in IEEE 1588.
Ethernet Timing & Priority Standards - All audio over Ethernet protocols require Priority, Sequence, & Sync
Differentiated Services / Quality of Service (DiffServ, QoS)
Priority by data type (Clock Sync and Audio Packets over Email)
Traffic prioritized based upon tags in IP Header (Layer 3)
Priority number assigned by manage switch to each packet
Real-time Transport Protocol (RTP)
Keeps data sequenced in the right order
Time stamp on UDP header
Works with RTCP (Real Time Control Protocol) for QoS and Sync
Variation: RTSP (Real Time Streaming Protocol) works on TCP and not UDP
Does not reserve resources or provide for quality of service
Precision Timing Protocol (PTP)

AVB fits low-cost, small-form-factor products such as this microphone. The overall trend is that music no longer lives on shelves or in CD racks, but in hard drives in home computers, and increasingly in the cloud. This brings about its own unique problems, not in the encoding system used, or the storage technology, but in distributing the audio from the storage media to the speakers. AVB features are all enabled by a global and port level configuration. Connecting these elements is the AVB-enabled switch (in the graphic above, the Extreme Networks® Summit® X440.) The role of the switch is to provide support for the control protocols: AVB is Ethernet’s next stage of convergence, delivering pitch perfect audio and crystal clear video seamlessly over the network
IP/Ethernet is bringing simplicity and features to audio and video as it has brought to services like VoIP, Storage and many more
High quality, perfectly synchronized A/V until now has been difficult to maintain
Standards work by the IEEE and the AVB standard changes everything, creating interoperability and mass-marketing equipment pricing
Benefits of AVB - Delivers predictable latency and precise synchronization, maximizing the functionality of AV – time synchronization and quality or service
Reduced complexity and Ease of use through interoperability between devices
Streamlines complex network set-up and management, the Infrastructure negotiates and manages the network for optimal prioritized media transport
AV traffic can co-exist with non-AV traffic on same Ethernet infrastructure
Role based control at the XYZ Account - XYZ Account can identify devices and apply policies based on device type all the way down to the port and or the AP. Policies can dynamically change based on the device a user is connecting with and where that user is located. Extreme Networks provides infrastructure to deliver customizable prioritization and scalable capacity via configurable and built-in intelligence, ensuring a comprehensive, superior quality experience. Furthermore, when deployed with Extreme Wireless XYZ Account can configure the network to ensure applications receive the bandwidth they require, while still limiting or preventing high speed streaming of music of video or even games.

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

– One loudness meas for all channels combined
– Gating to not count quiet periods
• Don’t allow gaming of measurement
• Level gating is in BS-1770-2, Dialog gating is not
7. Gating Review - What’s the big deal?
• Gating is critical
– Ensure correlation with loudness perception
– Helps prevent gaming by advertisers x.y
LKFS
• Gating is specified 2/3 different ways:
gate
– BS.1770-2, EBU, Most of the world – Cascaded level -10dB
– ATSC
• Short Form: No Gating, measure everything
• Long form (>2m) : Dialog Level – aka Dialog gating
• Measurements with different gating – need agreement with:
– Regulatory authority – What is being enforced
– Partners – Studio, Network, Broadcaster, Pay-TV operator
• Troubleshooting Apples v. oranges is not productive
8. Changes in Regulations
• Many countries moving forward with loudness regulation
– Brazil, France, …
– Almost all countries are using EBU /BS.1770-2 measurements
– Commercial v. Channel is regulated by all
– Other different items may be regulated
• Absolute channel tolerance or channel to channel difference (many)
• 5 day channel loudness drift – Italy
• Max S Measurement, - France
• Min Loudness Range – France
• Enforcement is starting….
– Italy- active, US - Dec 2012, many in 2013
– Time to get real
9. Considerations for International Carriage
• Content going to one country?
– Design and measure and alarm using local gating and regulations
• Content going to multiple countries?
– Same Gating – possibly different thresholds
• Measure with one gating,
• Alarm on most restrictive thresholds -24 LKFS
– Different Gating – e.g. Dialog and Cascaded level
• Measure content twice – once with each Gating
– Differences are unpredictable, no applicable rule of thumb
– -24 LKFS is NOT -23 LUFS!!!
• Apply tightest thresholds for each gating method (by country)
10. ATSC Network Certification – Why?
• Where does the blame fall in the chain?
– Programmer, Network, Broadcaster, MVPD?

11. ATSC Network Certification – Why?
• To allow broadcasters and MVPDs to
– Guarantee what they deliver
– Respond to complaint inquiries
– Not redo work performed by others
• Two step process if you do insert ads
– Get certification on Network
– Or certify it yourself
– Guarantee your ad inserts are compliant
12. ATSC Network Certification – What?
• Accessible
– Made generally available by Network (web)
– Allows all Broadcaster and MVPDS to access
• Content
– Not regulated – but must convince FCC/MVPDs
– Several approaches
– Legal statement certifiying compliance
– Measurements showing compliance
PGM1 -23.6 LKFS
COM12 -24.0 LKFS
PGM2 -24.1 LKFS

14. Observer Loudness Monitoring
• Loudness measurements -LKFS and LUFS -with gating
• Short (S), Medium (M) and Interval (I) measurements
• Up to 7 Short-form Interval (SI) - e.g 10s, 15s, 20s, 30s
• Up to 7 Long-form Interval (LI) - e.g. 6h, 1d, 5d
• Loudness Range (LRA) to measure audio companding
• Detailed 10Hz measurements - with Audio & Video
15. Observer Loudness Monitoring
• Graphing of S, M and I measurements over time
Multiple channel, multiple meas.
Graph <=> video time navigation
• Export :
Logged measurements as csv
Affidavit - A/V with burned in measurements
CSV values report
• Programs Certification Report export
With As-Run-Log Integration
Loudness of Every Asset
A/V affidavit

• Alarming (SNMP, email, visual)
Customizable alarming profiles based on SI and LI measurements
16. Observer Loggers with Loudness
• Software module available on
– Observer, Observer TS, RPM
• Observer family of products are loggers at the core
– Records audio, video & loudness measurements
continuously
– 3 to 365 days of storage
• Logger + measurement is very powerful
– Speeds troubleshooting, unambiguous affidavit
– Eliminates Network Station MVPD back and forth
Loudness logging is not a sea of numbers. It means
recording the audio, video,
and the loudness measurements.
