    Say farewell to eternally buffering, poor-quality videos thanks to researchers who have developed a new architecture for better-quality video streaming on mobile phones and across wireless networks.

    The new architecture – developed at the VTT Technical Research Centre of Finland – is based on utilising information gathered and combined from the video application, the network and the mobile phone. For example, information concerning quality, price and availability can be combined and utilised directly to better the service. This means better-quality videos and easier access for consumers, and users may even benefit from the new technology financially.

    From the perspective of operators and service providers, the new technology allows them to improve the quality of video streams without having to invest in new network capacity, giving them a cost-effective way to boost customer satisfaction.

    The volume of data transmitted across wireless and mobile networks continues to grow at a rapid rate. Videos already account for most of this data traffic, and their share is expected to grow even bigger in the near future. The new architecture is designed to optimise video streaming according to network capacity in order to achieve constant quality and efficient network resource usage.

    Thanks to the new architecture, video stream transfer speeds can be adjusted more efficiently to network resources available. This means that the quality of the video stream will not become unacceptable even when the transfer speed of a wireless connection suddenly changes due to congestion.

    The new architecture is also ideal for multi-access environments. In multi-access environments, video stream transfer speeds and therefore quality can be maximised by means of optimised handovers and concurrent utilisation of multiple access networks. If the current network connection is insufficient for video streaming, the task of receiving the stream can be handed over to another network or multiple networks used to receive the stream concurrently.
