Advancements Include Reduced Latency and Expanded Bandwidth Optimization Capabilities
“Low latency for OTT is extremely important, especially for the delivery of live sporting events,” said Darryl Jefferson, VP, Post Production Operations, NBC Sports Group. “Any lag time that exists between what’s happening in real time and being viewed on screen is truly unacceptable to viewers nowadays. We’re excited about the developments that Harmonic is making in the area of reduced latency for OTT video, and expect it to be a game-changer for broadcasters and other content providers as they strive to deliver the best possible quality across all devices.”
Harmonic’s low-latency streaming workflow is made possible by a unique combination of packaging content in the new Common Media Application Format (CMAF) and HTTP chunked transfer encoding. An emerging media standard for OTT delivery, CMAF reduces the need to package content separately for HLS and MPEG-DASH devices. The use of the new format in Harmonic multiscreen packaging and origin solutions not only improves the OTT viewing experience by reducing latency in live streaming, it also simplifies OTT distribution workflows.
Harmonic will also showcase an innovative new solution for dramatically improved video quality delivered over zero-rated mobile and xDSL networks, based on the company’s latest EyeQ™ technology advancements and new packaging technology expressly designed for constrained networks. Employing this new EyeQ packaging solution, operators can consistently deliver improved HD video quality to set-top boxes connected to low-bandwidth DSL lines, as well as to mobile devices connected to 3G/4G networks without exceeding the 1.5 Mbps bandwidth limitation of zero-rated mobile connections.
The EyeQ technology leverages the Human Visual System to reduce OTT video bit rate requirements by up to 50 percent without impacting video quality. Operators can employ this capability to deliver higher-resolution video streams that can be enjoyed on any device with vastly reduced buffering — even over constrained OTT/ABR networks.
Harmonic will showcase its latest innovations for broadcast and OTT video delivery at the 2017 NAB Show, booth SU1210.
