• The global video streaming market is growing
• Millennials watching content on their mobile devices and computers
• In the US, 86% of smartphone users watch video content on their phones
• Broadcasters need to brace up for the changing viewing styles by embracing Over-The-Top (OTT) workflows
• New technologies enable us to deliver high quality OTT services
• All of these brings new challenges
• The right set of Quality Control tools are a must to ensure that you stay ahead in the OTT race

Streaming Media Challenges
• New technologies
• Dramatic increase in content size
• New standards and formats
• Variety of device types
• Changing video production and delivery approaches
• Transition from a linear workflow infrastructure to OTT
Content QC & monitoring is a must for flawless video Delivery

Why End-to-End QC and Monitoring
• Built-in analytic capabilities of given components of the workflow are important and useful to handle specific issues, but do not address all the aspects of monitoring
• Dedicated QC and monitoring system can cover the whole workflow, keeping focus on overall quality and user experience
• Quality expectations are there at all points of the workflow, but experience is affected by issues raised in previous stages too
• Almost impossible to do all quality checks real time, so proper content preparation is important, thus different type of QC and monitoring features need to complete each others too
• An independent QC and monitoring solution from quality experts gives reliability, also ensuring long-term support and maintenance

Most comprehensive quality checks in the industry
• Baseband QC Checks
– Video signal levels, RGB color gamut, color bleeding, blotches, blur, defective pixels, black frames, color bars, chromaphase error, loudness, audio noise, etc.
• Compression Artifacts and In-depth Audio / Video Quality Checks
– Blockiness, Pixelation, Moire pattern, Ringing artifacts, language detection, burnt-in subtitle detection, etc.
• File Integrity & Standards Compliance
– Ensure that the file is not corrupt and has been encoded as per the standard to ensure that the downstream tools are able to play it without issues, including ABR compliances
– Very important in the OTT context (multiple devices, form factors / players from multitude of vendors)
• BATON can perform the following additional checks for ABR content:
– Checks to ensure each segment starts with an independent frame
– Checks to ensure that all variants of the content are properly aligned in terms of number of segments, segment duration, total duration and content structure
– Ensure consistency between metadata and actual content properties

Monitoring Encoder Boundary Points
• The Encoder Boundary Point (EBP) is a signaling mechanism for taking continuous streams conditioned for adaptive streaming and creating discrete chunks of decodable content.
• Using Orion, services can be grouped representing different bitrate variants of an ABR asset, then EBP information can be compared across services within an ABR group.

• 24x7 Proactive content monitoring required for early fault detection and resolution• Catch issues before your viewers start reporting problems
• For LIVE services, content monitoring at Origin is a must• Real-time environment, no offline QC possible• Cannot handoff content for delivery without checking
– Content availability and ABR compliance– DRM protection– Audio/Video quality
27
Why is Active Monitoring required ?
WWW.INTERRASYSTEMS.COM
• Active monitoring does not provide any information regarding real-user sessions
• Passive monitoring at end-devices is required to understand issues during playback at client devices
• Together, Active and Passive monitoring methods complement each other to • Provide an end-to-end network visibility• Determine fault sources in the network

Active & Passive Monitoring – complement each other

Edge Performance Monitor
• Monitors QoS & QoE to understand recurrent issues, their causes and the impact of anomalies on your customer base in real time
• Analytics & business intelligence; Collect user data, derive data consumption trends• Monitors real client user experience: Startup time, buffering ratio, number of stalls, play failures• Data collected from the end-devices can be correlated with active monitoring results using OCM

How does Youbora’s End-Device Monitoring work?
WWW.INTERRASYSTEMS.COM
– Buffer Ratio• Time spent in video buffering vs Play time
– Join Time• Time taken to display first frame of the requested video
– Interruptions• Number of times video stalled
– Play Failures• Could not play video
– Happiness Score• An overall score (1-10) based on all QoE metrics
37
What QoE Metrics are we using ?
WWW.INTERRASYSTEMS.COM 38
CHURN RATE INCREASES BY 50%
PLAYTIME INCREASES BY 2.3X
PLAY ERRORS AT 2% BUFFER RATIO > 2% BUFFER RATIO < 1%
User stickiness of QoE monitored services is 34% higher than non-monitored services
AUDIENCE DROP BY 40%
Impact of QoE on Audience Behaviour
CHURN RATE INCREASES BY 30%
JOIN TIME > 20 SEC.
