NTT announced that it has established a new video quality control technology based on Quality of Experience (QoE) in video streaming.
With the new technology, NTT claims that it managed to showcased reduction in traffic usage while maintaining the target QoE. NTT said based on the image quality and the playback stop time, QoE of a video is evaluated by an algorithm which then enables it to predict the future communication quality considering the user's environment. This can optimally control the bitrate in the midst of video streaming so as to achieve the preset QoE target.
This video streaming technology enables users to maximize QoE, and to reduce the traffic while maintaining sufficient QoE. NTT has applied this technology to the experimental smartphone application for NTT Plala.
It was confirmed by the demonstration that even in a crowded environment, users can smoothly watch videos with little stress, and service providers can deliver videos efficiently by streaming in sufficient video quality, claims NTT.
This technology is applicable to various video streaming services, CDN services, etc. It can be incorporated with minor modification to distribution server or smartphone application, said NTT.
NTT aims to further enhance the technology to improve the user experience and to streamline network utilization and reduce costs.
