Limelight Realtime Streaming’s sub-second latency enables you to create interactive applications that include live realtime data, making it easy to deliver online viewing experiences that open up new possibilities for how live content distributors interact with viewers. As viewers increasingly consume content online, one of the primary complaints with watching live sports and other realtime events is the delay between the broadcast feed and the online stream. Limelight Realtime Streaming is the first scalable, sub-second live video streaming solution that’s natively supported by major browsers without special plug-ins.
Traditional HTTP live streaming breaks the video into small segments or chunks that must be buffered prior to playback, causing live streams to lag realtime by 30 seconds or more. It’s possible to reduce the size of the chunks to decrease the delay, but making them too small increases the chance viewers will experience video rebuffering and other playback issues. While streaming latency may be acceptable for some live streaming use cases, it does not satisfy the requirements for realtime workflows that require true sub-second latency for viewers everywhere.
Limelight Realtime Streaming is the first scalable solution that allows video to be streamed from anywhere, to viewers everywhere, in less than a second. It utilizes the industry-standard WebRTC video format to deliver reliable, broadcast-quality, realtime video streaming using the UDP data transfer protocol. Video streams do not need to be segmented into chunks and buffered before they are viewed, eliminating streaming delays. WebRTC is natively supported in major web browsers without needing special plug-ins or custom applications, making it easy for viewers to enjoy realtime video on a variety of devices. Limelight Realtime Streaming leverages Limelight’s global private network which has the capacity, reach, and connectivity to ensure a high-quality, realtime viewing experience for audiences—wherever they are. In addition to live global sub-second video delivery, Limelight Realtime Streaming provides numerous tools and capabilities to help you maximize the value of your live streams. Adaptive Bitrate streaming delivers the highest possible picture quality to each viewer, even over changing network conditions, ensuring every viewer has the best possible online experience and keeps coming back for more. Integrated content security and access control capabilities make it easy to stop unauthorized viewing of your live streams, including the ability to block access to streams by geolocation. Analytics are also available to help you understand how and where your content is being viewed and better engage your audience.
Limelight Realtime Streaming’s sub-second live video enables you to create interactive online experiences by integrating live data with video. You can share data with sports fans so they can vote for the player of the match, or wager on who will score the next goal, right from their computer or mobile device. Fans of eSports can participate in event polling along with the live in-arena audience. Remote participants in live auctions will be able to bid in realtime along with at event bidders. Limelight Realtime Streaming opens up new business opportunities in sports, gaming, auctions, and more by making live viewing a more interactive social experience.
