Mobile video quality testing

How to manage the video traffic that drives the data explosion in mobile networks?

The vast majority of the traffic in mobile networks today comes from video services (> 60%). Cisco VNI Mobile forecasts that mobile video will grow to 78% of all mobile traffic by 2021. Consequently, the user's perception of video service quality has an increasing impact on overall user satisfaction and the operators’ success.

How to test your own video services vs. OTT applications from third parties?

The most popular video services today are OTT services (e.g. YouTube, Netflix, Hulu, etc.). If you want to know how OTT applications are performing in your network, then you should use precisely those applications to conduct tests and measure the perceived quality of experience (QoE).

Social media services are starting to offer video services (e.g. Facebook, WhatsApp, etc.). Mobile network operators are also starting to offer their own video services (often live video services).

Rohde & Schwarz Mobile Network Testing can provide the most reliable way to measure the QoE of the video applications and the quality of the network using e.g. the Network Performance Test (capacity and coverage).

Visual quality and video MOS based on subjective perception

Video services are very popular and so is their use today in various services and media. YouTube and Netflix are merely the pioneers in video streaming; many other services have followed. Broadcasting stations move more and more content online, videos are shared via social media, and peer-to-peer applications are on the rise; for example, video chat services (e.g. Skype), or the private broadcasting of live captured videos (e.g. Periscope). But what’s their visual quality like?

Optimizing a network’s readiness for video transmission

In previous entries of this blog series about the challenges of mobile video services, we discussed video quality as a perceived metric, how it can be measured, and how quality measuring algorithms work. To conclude the series, this post focuses on how to apply a video quality measure to quantify video services as consumed by subscribers. What are the challenges and what are the results telling you about your network?

Overview of video services in mobile networks

Arnd Sibila, technology marketing manager, explains the growing importance of video quality in mobile networks, and the limitations that mobile operators face to control this quality that is dependent on the network resources and how these resources are allocated.

User-perceived network performance test

Arnd Sibila, technology marketing manager, explains how to measure the real network performance, capacity and coverage, as perceived by end-users. In the video, Arnd describes the scope of tests performed and what parameters to consider in making these tests.

Testing perceived video quality in mobile networks - part I and II

The video series explains how objective methods and algorithms, such as MOS, J.343.1, etc., are used to measure the subjective nature of video quality in a mobile network. It show in detail how video quality can and should be tested using J.343.1. As a very robust algorithm, J.343.1 takes into account all video characteristics into a single score; e.g., coding, compression, rescaling artifacts, perceived freezing, etc.

End-to-end assessment of mobile video services

Videos are the most popular web content and have long formed the bulk of data volume in mobile networks. Which is why not only video consumers but also video service providers and network operators have a vested interest in a high quality experience. Mobile measuring systems assess this automatically just as reliable as human viewers.
