Brix Networks Announces Enhanced IP Video Quality Algorithm To Ensure Success In IPTV Rollouts

Brix Networks, the trusted provider of the most widely deployed service assurance solutions for interactive applications, today announced an enhanced IP video quality algorithm — the Brix Video Quality Index (Brix VQI) — that ensures providers’ success with their IPTV rollouts.
“In order to effectively deliver profitable triple-play services, cultivate customer loyalty, and grow market share, it is essential that network operators provide their subscribers with high-quality offerings,” said Robert Travis, director of product marketing, Brix Networks. “Our VQI technology is a critical component of our comprehensive service assurance platform, and helps determine the overall quality of a variety of existing and emerging IP-based video applications, such as IPTV, video-ondemand, and interactive video.”
The Brix VQI is an objective measurement scale for video over IP networks and applications providing accurate, easy-to-understand metrics for highly distributed, large-scale carrier and enterprise networks. The Brix VQI incorporates the impact of network transmission quality — the most important factor contributing to video quality — and quantifies the effect latency, packet loss, jitter, packet discards, buffering, and re-buffering events have on a video service.
With today’s announcement, the Brix VQI has been enhanced to be “application aware,” meaning it can distinguish, analyze, and correlate the key performance indicators (KPIs) related to data impairments that, in turn, contribute to picture jerkiness, blurriness, or no picture in video-based services.
“Developed with ongoing standards initiatives in mind, Brix VQI is an innovative video quality algorithm that yields useable metrics to generate an IP video quality score — per video stream — that accurately represents the user’s quality of experience,” said Brix Networks’ chief technology officer, Kaynam Hedayat. “VQI builds on our extensive industry-leading experience in VoIP networks, and quantifies the impact that latency, initial wait time, network jitter, packet loss, and other applicationlevel impairments have on the overall performance of an IP video service.”
