Video Quality Testing Services

Fit4Launch Video Quality Testing Services objectively evaluate and report on lab- and live-network streaming video performance from the subscriber's perspective. And, because Fit4Launch Video Quality Testing Services support any mobile device, screen sizes & resolutions, we deliver consistent test results as devices change, reducing long-term testing costs. With Fit4Launch Video Quality Testing Services, you no longer have to rely on subjective video testing, which can vary based on who is performing the tests and the issues for which they are looking.

With Fit4Launch Video Quality Testing Services, we measure how streaming video quality changes under differing network conditions. We take into account all the elements that might affect what the subscriber sees, including content encoding, content delivery, network performance, and device playback. Fit4Launch Video Quality Testing Services also provide a related audio performance score and information on audio/video synchronization. By understanding, up front, how video streaming operates under real network conditions, you can proactively avoid performance issues.

Poor Video Quality Will Drive Subscribers Away

More than just frame error rate, only Metrico's video quality testing technology captures the content—which frames were missing or in error—during a video streaming test. Alternatives can only report that an error in the radio link occurred, they can't tell you what frames were missing. Only Metrico delivers this extra context, which provides a more complete assessment of the video quality and is a more accurate way to measure and report video quality.

Normalizing for Network Variability	In every test case, the device under evaluation is tested in parallel with one or more reference devices (golden phone), in order to provide indication for network variability and a numerical point for normalization of the collected performance statistics.
Collecting Large Sample Sizes	Using standard statistical techniques, Metrico collects sufficient samples to ensure repeatability of performance metrics.
Developing Performance Thresholds	Every service provider sets its own performance thresholds using performance percentiles extracted from our large database of device performance. For example, a carrier can select as the threshold the 25th percentile of performance for all devices tested on its network over time, thereby rejecting the bottom quartile of devices.
