RAS migrates with Synamedia, nanocosmos shrinks latency and more

TVBEurope rounds up the top technology stories of the day

Italian public broadcaster RAS has deployed Synamedia’s virtualised Digital Content Manager (DCM) for its planned migration from DVB-T SD/HD to DVB-T2/HEVC HD services by June 2022.

RAS relocated its offices in Q4 2019, requiring all of the broadcaster’s technology systems to be moved without disruption to TV/radio services or to its public safety DTT emergency alert system.

German software house Dimetis integrated Synamedia’s hybrid DCM/virtualised DCM with its BOSS BROADCAST Manager (BBM) software platform and managed the technology move to the new office.

Julien Signes, SVP and general manager, video network at Synamedia, said: “The flexible design of our software-centric DCM is proving to be highly appealing to public broadcasters such as RAS.

“RAS is now benefitting from the freedom of our hybrid headend that delivers the ultimate in picture quality and will enable them to transition smoothly to a DVB-T2 software-based future by their 2022 deadline.”

nanocosmos shrinks latency 

nanocosmos has introduced new enhancements to its nanoStream Cloud service, delivering an end-to-end latency of around one second for interactive video streaming applications.

nanoStream Cloud leverages a combination of software analytics, global CDN services and an ABR player to achieve ultra-low-latency live video streaming.

The service enables ABR playback on any mobile or desktop browser, including iOS Safari, via the nanoStream H5Live Player, which automatically adjusts video quality based on network conditions on the viewer side to avoid buffering.

nanocosmos CEO and founder Oliver Lietz said: “Ultra-low-latency live streaming opens up a variety of exciting opportunities for multiple markets, especially those focused on driving audience engagement.

“As nanoStream Cloud deployments grow across the globe, we’re excited to introduce several new enhancements that answer our customers’ live streaming challenges.

“Through ABR playback, transcoding and action-based analytics on the nanoStream Cloud service, we’re helping to ensure that service providers can deliver an interactive and lean-forward type of video experience with ultra-low-latency that is critical for live streaming.”

Crystal Vision unveils video delays 

Crystal Vision has released four variable video delays that can work with IP, SDI or both at the same time, providing up to 32 seconds of delay.

The software apps run on MARBLE-V1 media processor hardware, enabling broadcast engineers to select the required number of channels (single, dual or triple) and the required amount of delay (up to 100, 200, 400 or 800 frames).

Crystal Vision said these are the industry’s first video delays to offer IP connectivity, supporting both SMPTE ST 2022 and ST 2110 video over 10GbE IP networks.

The delay is adjustable in steps of frames, with the length of the delay in seconds dependent on the video standard, with 31 different SDI formats supported.

Crystal Vision MD Philip Scofield said: “Crystal Vision video delays have always helped people with system integration, particularly with virtual reality systems.

“This latest range of video delays helps solve the same problems when working with IP systems – as well as delay requirements unique to IP systems and the mixing of IP and SDI systems.”
