Multi-party audiovisual systems for Wide Area Networks

直播视频是当前消费者网络体验的基石。我们吃的，喝的， 观看，体验通过越来越多的设备流入我们的生活。然而，现场互动 视频流仍处于形成阶段。Skype等网络会议远不是高清 (高清)广播质量而广播质量网络视频流目前仅限于 定向电视模型。广播流通过电缆从摄像机到卫星或通过以下方式发送到互联网 从智能手机到无线网络的WiFi。远程位置的视频流越来越多地被启用 由专门的视频编码器提供。这些单元对来自摄像机的数据进行编码，并将其传输到互联网 通过卫星或移动热点。然而，这仍然是纯粹简单的点对点广播。这个 传统受众仍然存在，在这一过程中并不是平等的参与者。实时视频交互是 现在互联网的最终目标是。 总部设在温哥华的Max Q Live正在开发一个基于互动流媒体视频的全球门户网站 从地球上的任何位置完成这项任务需要 卫星传输和广播摄像机。广播到网络交互的关键限制是 广播和网络格式之间的40秒延迟。Max和SFU的一个工程团队已经创造了 这是一项突破性技术，首次允许网络视频流与广播互动 没有延迟的源。该项目得到了之前NSERC Engage赠款的支持。这证明了 这项技术利用了局域网(LAN)设置，消除了现有的40秒延迟。 该项目的目标是在最初突破的基础上，将其扩展到广域网(WAN) 完全用于商业用途的申请。这将使Max Q Live能够在2016年秋季全面运营。

Live streaming video is the building block of the current consumer web experience. Everything we eat, drink, watch, and experience is streamed into our lives on an ever-growing list of devices. However, live interactive video streaming is still at a formative stage. Network conferencing such as Skype is far from High Definition (HD) broadcast quality while broadcast quality video streaming to the web is currently limited to the single direction TV model. Broadcast streaming is launched to the Internet via cable from camera to satellite or by WiFi from smart phones to wireless networks. Increasingly, video streaming from remote locations is enabled by specialized video encoders. These units encode the data from a video camera and stream it to the Internet via satellite or mobile hot spots. However, this is still pure and simple point-to-point broadcasting. The traditional audience is still in place and is not equal participants in the process. Real time video interaction is now the end goal of the Internet. Based in Vancouver, MAX Q Live is developing a Global Web Portal built on interactively streaming video both to and from the web online in real time 24/7. To accomplish this task from any location on earth requires satellite transmission and a broadcast camera. The key limitation for broadcast to web interactivity has been a 40-second latency between the broadcast and web formats. MAX and an engineering team at SFU have created a breakthrough technology that, for the first time, allows the web video stream to interact with a broadcast source without latency. The project was supported by a previous NSERC Engage grant. It was a proof of technology that utilized a Local Area Network (LAN) setup that eliminated the existing delay of 40 seconds. The goal of this project is to build on the initial breakthrough and extend it to a Wide Area Network (WAN) application for full commercial use. This will position MAX Q Live to launch full operations in the Fall 2016.
