Title:
QUALITY OF USER EXPERIENCE TESTING FOR VIDEO TRANSMISSIONS
Document Type and Number:
WIPO Patent Application WO/2013/056123
Kind Code:
A3
Abstract:
Techniques for calculating quality of user experience (QoE) scores for video streams as played on receiving devices are described herein. Prior to calculating a QoE score, a device receives a video of a display screen of a receiving device captured while the receiving device plays a video stream. The device also receives transmission metrics from at least one device engaged in the transmission of the video stream to the receiving device. The device then calculates the QoE score for that received video based at least in part on a reference video, the transmission metrics, and one or more QoE models. Additionally, prior to receiving the video or the transmission metrics, the device may automate the transmission of the reference video as the video stream from a sending device to the receiving device over at least one network emulator, including providing network impairment settings to the network emulator.
