comprehensive network intelligence and visibility
for multiscreen adaptive bit rate video services.
Key Benefits
Maximize Overall Investment
y Prevent issues associated with delivery
of advertising content maximizing
advertising revenue
y Reduce subscriber churn by ensuring quality
and consistent delivery of video and audio
streams to the subscribers
y Minimize overall operational expenses
y Identify problems before subscribers are
impacted by validating manifest files and
ensuring all streams/variants are available
for players
y Reduce MTTR by segmenting the network
rather than relying only on Player statistics
y View events and statistics in real-time for
quick problem isolation
y Open APIs to incorporate unbiased program
and availability data for OSS/BSS systems for
automation, performance management, post-
mortem root cause analysis and
other applications
y Intuitive, easy to use — simplistic, user
interface focused on Video Quality of
Experience (QoE), which can be used by
NOC personnel through to detailed
technical support
y Reduction in overall capital outlay. Scale with
software rather than hardware, leveraging
virtualization and containerization. Spin up
and spin down agents as required for
maximum flexibility
The VSA Agent is a highly cost-effective and scalable
solution for Unicast and ABR video services. This
provides visibility and identifies the transport, CDN,
DNS, and video asset characteristics information that
are critical in delivering a unicast service.
The VSA Agent performs turn-up and service testing
using distributed software agents to monitor live and
VoD services. It simulates multiple users requesting live
and Video on Demand (VoD) content, runs load tests
to verify capacity, and analyzes video MOS. Additional
features include:
y Ad validation
y CDN certification
y Packet retransmit monitoring
y Support for SDN/NFV architectures

Key Features
y Proactively monitor and validate all unicast
services
y Segment network issues impacting service to
isolate problems quicker
y Monitor and identify transport, CDN and DNS
issues impacting the overall service
y Verify availability and understand compliance.
y Simultaneously monitors hundreds of assets at
various bit rates to ensure integrity and quality
y Monitor availability  Still/Black detection,
audio loss, program loss
y Monitor Compliance  Loudness (CALM)
and Closed Captioning
y Presents insights in an unbiased integrated
and visually-relevant way
y Streamline and integrate with in-house
systems using non-proprietary open and
powerful unbiased APIs
VSA Agent provides video assurance monitoring
software (Figure 1) in a virtual environment which
can be easily deployed at the relevant points to allow
segmenting of the network. The product addresses the
most important assurance and analytics KPI’s to ensure
your service runs smoothly. It also has a very simple,
easy to use user interface that provides real-time quick
analytics and actions to identify and correct issues
impacting service delivery.
Managing hundreds or thousands of live URLs is a
challenge. VSA Agent allows the easy import of video
assets with easy job creation via a simplified drag and
drop user interface, or these tasks can be scripted for a
completely automated implementation.
Characterizing program availability solely based on
player statistics can be misleading as they are biased
towards user devices and programs being streamed
at any given point in time. Unbiased statistics and
relevant KPI information provided by VSA Agent gives
an agnostic view of availability shown in real time,
providing an accurate and instantaneous view of
existing/potential issues in the network (Figure 2).
