DUBLIN--(BUSINESS WIRE)--The "Quantifying the Video Quality of eMBMS/LTE-Broadcast in a Commercial LTE Network" report has been added to ResearchAndMarkets.com's offering.
The author conducted its second independent benchmark study of LTE-Broadcast and how it compares with unicast delivery mechanisms. For this study, the author focused primarily on the video MOS (Mean Opinion Score), which provides an objective quantification of the video quality.
Highlights of the Report include the following:
- Thanks - The author did this study in collaboration with Spirent Communications who provided its Umetrix platform to quantify the video quality (VMOS) with a non-reference video.
- Methodology - The author leveraged Telstra's commercial LTE network in Australia. They used up to 21 Galaxy S8 and S8 Plus smartphones to generate loading in Band 28. By varying the number of devices using unicast they could compare and contrast the video quality with LTE-Broadcast, which also resided in Band28.
- Background - This report marks the authors second benchmark study of LTE-Broadcast. In the authors first study, they focused primarily on the impact of unicast and LTE-Broadcast on the network as well as various video delivery metrics. In that study, published two years ago, the author provided strong proof that the crossover point in efficiency between LTE-B and unicast occurs with a few low number of subscribers (in the very low single digits).
- The Results - The results of this eMBMS benchmark study prove there are substantial improvements in the video quality with LTE-B versus unicast. Further, the author only needed to use a handful of smartphones to document the improvements. Without question, in venues where there is a large number of people watching the same video content, the benefits of LTE-B on the user experience will be even more pronounced.
