Product Quick Find

Product Listing

Fovea is a streaming video analysis tool that is designed to monitor up to 500 simultaneous video streams.
The unit gives the user flexibility to serve a wide range of applications associated with network performance and its ability to support video applications simulating a user watching and changing channels.
While watching a channel, quality measurements are performed to determine the user's overall quality experience while channel surfing, Zap Time measurements are performed to determine how quickly network elements respond to commands.

Capabilities

Fovea simulates hundreds of IPTV subscribers/Set Top Boxes
(STBs) independently changing channels and watching video.
Fovea GoldenEyes simultaneously monitor hundreds of Multicast IPTV streams in real-time, quantifying the Quality of Experience (QOE) per viewer.
Fovea provides the industry’s first Video Reception Index (VRI), a measurement that quantifies the effect of lost and corrupted video frames on the viewer.
Fovea presents the following measurements per viewer endpoint:
MPEG Transport Stream (TS) packet metrics
RFC 4445, RFC 3550 and ETSI TR 101 290
Video I, P and B frame metrics and detail
Perceptual Quality measurements
Zap Times
Fovea’s simple GUI interface increases productivity by enabling the user to configure a test within minutes.

Tests Performed

Ameritec has incorporated into Fovea a comprehensive set of measurements designed to best depict the user's experience as it pertains to video quality.
Utilising a standards based approach, Ameritec has incorporated ETSI TR101290, Media Delivery Index (RFC4445) and RFC3550 measurements as well as perceptual quality metrics such as MOS-V for each of the TS streams configured, up to a maximum of 500 streams.
Additionally, Fovea provides a Video Reception Index measurement that captures two critical components of a video quality problem:

(1) the percentage of bad frames and

(2) the duration of the longest video degradation in seconds. Fovea also measures Zap Times.

Summary

With a wide range of simulation and leading monitoring capability, Ameritec with the Fovea have produced a simple to use tool for all IPTV testers who need to know what’s happening on their system.
With its detailed analysis capabilities Fovea provides not only qualitative but also a quantitative measurements that will be a timesaving benefit to all engineers in this area.
