Erstream OTT comes with watermarking solution
Technology company Erstream has integrated NexGuard forensic watermarking into its online video delivery platform . Erstream offers an over-the-top ( OTT ) video delivery solution for live and on-demand , which includes multi-bitrate encoding , CDN delivery , edge storage , ingest and content management solutions . Harrie Tholen , managing director of NexGuard , said : “ Our integration with Erstream , which is particularly targeting live sports , demonstrates how subscriber-level watermarking in OTT services enables our customers to identify piracy down to the subscriber level very quickly and stop illegal streams at their source .”

To maintain the quality of programmes being aired , broadcasters rely on their test and measurement ( T & M ) equipment to ensure signals remain within broadcast standards . That is why attention is paid on features that come with these tools , to make sure that all , if not most , T & M needs are met . Millette
Manalo-Burgos reports .
With content production moving towards 4K / Ultra HD ( UHD ) and 8K , it is but logical that T & M solutions providers are devising features for their systems that pay attention to this trend .
Alan Wheable , senior technical author at Omnitek , tells APB : “ With more 4K / UHD material being created by more companies , there is a greater requirement for T & M equipment that can be used in an operating environment to ensure that programme quality can be maintained , regardless of the
physical connection being used .”
With a focus on programme making , tools such as 4K / UHD waveform monitoring that supports high dynamic range ( HDR ) have become a priority , he adds .
Thus , Omnitek is offering its Ultra 4K Tool Box which supports SDI , HDMI and DisplayPort interfaces . This feature allows the testing of the physical interfaces used in a number of multi-screen implementations .
“ Omnitek ’ s IP consultancy is also working with a number of brand name companies in Asia-Pacific countries to provide solutions for current and future display challenges that they are facing ,” adds Wheable , who says the requirements for test and measurement equipment to support 4K / UHD are now widely understood , while a number of challenges faced by manufacturers of 4K / UHD equipment have been resolved .
As for 8K , Wheable reveals : “ The challenges that 8K bring are that of
Challenges on working on 4K / 8K formats
What are the challenges on working on 4K and 8K formats from the T & M perspective ? Phabrix ’ s Paul Nicholls gives an outline : The step from ‘ full HD ’ to ‘ UHDTV ’ is a very significant one . Current proposals see this as a three-phase development . This phased approach is necessary due to the very significant technical hurdles at each stage . Phase one has begun ; however , ultimately UHDTV will provide a user experience incorporating : n Higher spatial resolution : UHDTV1 ( 3840 x 2160 ), UHDTV2 ( 7680 x 4320 ). n High Dynamic Range ( HDR ): Camera and display technology taking the user experience from the current display technology reference luminance of 120 cd / m ² to over 10,000 cd / m ². n High frame rates ( HFR ): 100 / 120Hz frame rates .
Phabrix released the Qx for UHDTV test and measurement .

A quick scan of the table of UHDTV standards gives a feel for the video payload requirements associated with UHDTV — and its challenges .
n Wide Colour Gamut ( WCG ): A new colour space at Rec . 2020 with twice the CIE 1931 colour space area as ‘ full HD ’ ( Rec . 709 ).
A new audio experience with opportunities for object-based audio , 96kHz sampling , and up to 22.2 surround sound .
Handling these payloads alone and providing instrumentation is a difficult enough task . Add to this the complications of supporting coaxial SDI to 12Gbps , opti- cal SDI to 12Gbs and 10G Ethernet , with or without compression , and the challenge is significant .
Technologically , we have released a new product , the Phabrix Qx , for UHDTV T & M . The Qx represents the only currently available high-end 12G-capable real-time physical-layer eye pattern analyser , providing accurate SMPTE-compliant measurements of eye amplitude rise time , fall time , overshoot , undershoot , timing and alignment jitter .
The ‘ holy grail ’ of effective UHDTV SDI physical-layer analysis is bandwidth . Without appropriate bandwidth you remain in the dark .
