Video Testing | Domestic Network Testing

A quality assurance solution to guarantee the best experience for live and on demand video

Video services are critical to mobile operators’ strategies. Already in 2022 82% of all IP traffic was video. To stay competitive, reduce OPEX and churn, and tap into new revenue streams, service providers must offer absolute faultless video quality, a key factor driving customer satisfaction. 

Mobileum’s Video Quality Testing Suite is an end-to-end active service assurance solution to test, monitor, troubleshoot, and benchmark video services. It is a very flexible quality of experience testing approach for both live and on demand content with the focus on the customer perspective. Real-time alarms flag quality problems before a business impact.

Powerful metrics generated by 3 quality complementary testing methods

Mobielums’ Video Quality testing solution addresses a wide range of use cases that thoroughly map video services based on key quality of service and experience criteria.  It uses these analysis methods:
  • Frame Level Analysis: Available for Set Top Boxes (STB) and provides standardized KPIs, independent of protocols or codecs. It leverages the capabilities of the Media Processing Unit (MPU) to capture and process on-demand or live video using a non-referenced model.
  • IP Level Analysis: Available for STB, YouTube app on smartphones and browsers. KPIs are generated based on bitstream analysis. It supports encrypted and unencrypted transmission.
  • Application level analysis, part of Mobileum’s Smartphone Experience: A flexible tool to test and monitor any video app, with user-defined scripts and high level KPIs. A video streaming app gives insight into the user experience.

A robust media processing unit for video quality testing

Mobileum’s Media Processing Unit (MPU) uses frame level analysis, one of the most flexible methods for testing and monitoring live or on demand video content.

It captures the video stream directly on the HDMI interface from any HDMI output, such as Set-Top Box or Apple TV. The video source can be live or on-demand TV, OTT, etc. The MPU processes the captured video stream and analyzes each captured frame generating an extensive set of KIPs easily visualized in different charts and split according to the section in the video delivery chain more likely to introduce degradation. Alarms are based on defined KPI-distortion thresholds.

Examples KPIs for HDMI video quality as defined by the Video Quality Experts Group (VQEG) are:
  • Capturing & processing (content preparation)
  • Transmission (Delivery & Access)
  • Display & menu (End-Point)
  • IP KPIs

Video quality testing for OTT applications to prevent audience loss

With OTT services available to the user at the click of a button, the risk of losing business is higher than ever. If content does not start streaming within 2 seconds, they will abandon the video. Each additional second of delay costs 6% of your audience. A quarter of it will be lost after 5 seconds! 

Mobileum’s Smartphone Experience Local Unit (SX-LU) generates an in-depth analysis of OTT video services performance, ensuring the best quality of experience. Our user-friendly flexible solution allows new test cases to be easily created and existing ones to be changed within minutes. Users can create test scripts for any video app and generate KPIs such as app launch duration, video start delay, content availability, etc.

Pre-defined test cases include:
  • Smartphone YouTube testing
  • Video app testing using Smartphone Experience studio

YouTube test case

YouTube is one of the most popular video streaming services and is accessed from both mobile and fixed networks. Users typically associate degradation in performance with their network provider.

Mobileum’s YouTube test allows providers to validate their service perception by identifying the users’ real experience directly on the smartphone or data capable interfaces. The video quality testing is based on capturing and analyzing the Packet Capture (PCAP) associated with a YouTube session and the test cases provide a Mean Opinion Score (MOS) for audio and video, in case of unencrypted video streams. For encrypted video streams, MOS-B is provided. Our tests also generate TCP/IP (Transmission Control Protocol/Internet Protocol) KPIs that indicate packet loss, throughput, and bitrate.

Video app testing with the Smartphone Experience Studio

When considering mobile video applications, the app's performance is equally important as the performance of the video stream. Mobileum offers an easy-to-use solution for testing video applications on Android and iOS devices.

Using the SX-LU and the flexibility of the Smartphone Experience Studio users can create test scenarios for any video app and monitor KPIs such as app launch duration, video start delay or video availability.

In addition, KPIs can be extracted from the diagnosis data provided by the video player and complemented with screenshots and key test steps. Test results are centralized and can be easily used for reporting, troubleshooting and alarming.

YouTube streaming test case

Real-time video quality measurement is the most effective method to evaluate a network’s readiness for video services. As video services are often accessed from PCs or laptops, our YouTube Streaming test case determines user experience based on how they perceive a service. Mobileum’s YouTube Streaming testing validates video quality by automating a real browser and playing a particular video.

It is a testing method that captures the YouTube service performance, as experienced by the end user. The Test Case provides KPIs for service performance and video quality, determined by measurements extracted directly from the native YouTube diagnostics tool. YouTube page access and browsing durations are also important metrics provided by our tool. Finally, using the same method as in the Smartphone based testing, the PCAP is analyzed to generate IP layer KPIs.

Netflix streaming test case

Netflix is one of the most popular video streaming services. Mobileum provides an easy-to-use test case that can be used for monitoring the availability and performance of Netflix. Using browser automation, the test case logins into Netflix and selects a video for playback. Once a title is activated to play, the native Netflix player is loaded in the browser and the video starts.

The test case is flexible in both start and end position of the video stream. Once the video is streamed for a parametrized duration, the test case “signs-out” and starts the post-processing of QoE KPIs. In the end, the test case activates the diagnostic mode of the player and extracts KPIs from the Netflix player diagnosis tool. The KPIs show buffer health, playing resolution and bitrate, audio track information, browsing step duration, etc. Validation is done for each step and screenshots are provided as result files.

Video Performance Testing

Validate the best user experience, the make-or-break video service metric

Video quality tested in different points from different perspectives for the best service

To thoroughly map video service performance, Mobileum’s video testing solution includes a range of probes and testing equipment.

Quality is then verified using different analysis layers, which address the following use cases: Set Top Boxes (IPTV and Video on Demand) and OTT Services (YouTube video quality, browser-based Netflix streaming, and video app). They can be deployed in different points of the video delivery path: at the service provider (sends the video), at the network provider (transmits the video), and at the end-user premise (receives the video).

The latter could be a VIP customer or a shop, where you can demonstrate video quality to attract new customers.
