NEP UK has installed multiple Selenio Network Processor (SNP) appliances from Imagine Communications in four of its largest outside broadcast trucks to provide an automated workflow for delivering 4K/UHD as well as HD, in SDR and HDR.
The SNP is a software-defined IP and SDI signal processor. Each 1U device features four independent processing blocks, each of which can adopt personalities defined by the software. Applications are available on individual licenses, so users can define the exact functionality they require and reconfigure their SNPs as tasks demand, making them particularly suited to OB work.

NEP UK has ordered a mix of licences for signal format conversion including HD, 3G and 4K, as well as dynamic range conversion between SDR, HLG, PQ and Slog3.
Many of the sports broadcasters NEP UK provides facilities for offer UHD coverage as an option for subscribers, but they also have to maintain the highest quality HD output possible to serve the majority of viewers.
Chris Cannon, director of technical operations, NEP UK, said: “We have adopted the use of the SNP as a high-density signal conversion engine. Given the tight confines of an outside broadcast truck, we really appreciate we can get eight UHD conversion channels in just 1RU, and that includes signal format conversion, as well as SDR-HDR conversion, the latter through the built-in conversion pipeline or through customer-defined LUTs. We set and forget the SNPs: they perform well, take up little rack space, consume less power, and deliver the full variety of HD, UHD, SDR and HDR outputs we need.”
