if the operator is required to monitor 60 4K / UHD sources , for example , the operator can use 20 cards networked together , with each card managing three full 4K / UHD sources .”
In parallel to the input stage , vm _ dmv64-4 also features an output stage capable of creating up to four 3G mosaics with 64 sources / picture-in-picture ( PiPs ) each , or two 4K / UHD mosaics with 128 sources / PiPs each . The output stage compiles a mosaic from the appropriate mipmaps needed , taking into account the size the user requests for the PiP . The output stage can use both mipmaps that it has generated by its own input stage , or by subscribing to other mipmaps from the network .
“ If a user wanted to see a nine-PiP output with 4K / UHD sources , the output stage will subscribe to the mipmap that closest resembles the size that is requested from each of the sources , and then make the final adjustments
Capturing images as close as possible to reality is an endless quest for content producers . In search of these better and higher resolution images , the industry has developed technologies such as 4K / Ultra HD ( UHD ) and high dynamic range ( HDR ) to empower content producers to capture “ more and better pixels ” within each shot .
And along the production chain , quality control equipment like a broadcast monitor is a critical tool in ensuring content producers are getting better pixels and wider colour gamut in order to deliver “ more realistic and immersive ” content and pictures , suggested Poh Cheng Yong , vice-president of sales , Postium .
He told APB : “ Most of the acquisition devices available in the market today are already supporting 4K / UHD and even higher resolutions . However , content producers often master the content into HD or standard dynamic range ( SDR ) due to the shortage of theatres and places in Asia that are capable of projecting HDR content .
“ Broadcasters and local studios in Asia have come to realise the importance and growing appetite of consumers who are demanding better quality picture in their 4K / UHD TV sets . Therefore , we will be seeing a mixed SDR-HDR ecosystem for the foreseeable future as some countries in Asia have just adopted HD not long ago .”
For Postium , the broadcast display manufacturer has supplied its broadcast reference monitors to two South Korean broadcasters , Korean Broadcasting System ( KBS ) and Munhwa Broadcasting Corporation ( MBC ). For MBC , Postium provided its new OBM series 4K / UHD monitors for the network ’ s new 4K / UHD OB truck . A total of 14 units of 4K / UHD monitors and 13 units of HD monitors , ranging from 9 ” to 55 ”, were installed in the OB truck .
As for KBS , Postium similarly provided its OBM series 4K / UHD monitors . The models consist of 24 ”, 31 ” and 55 ” 4K / UHD monitors , including 12 units of OBM-U310 . In February this year , the OBM-U series 4K / UHD monitors were used for 4K / UHD broadcasting in the International Broadcast Centre during the 2018 Winter Olympic Games in PyeongChang , South Korea . Following the conclusion of the tournament , the monitors were then moved to the 4K / UHD control room in KBS . before it provides the output ,” Hedkvist adds . “ The output can be both over SDI and IP . This way , Lawo ’ s multiviewers can provide infinite scalability not only for HD / 3G but also 4K / UHD and 12G sources . Plus , they are fully HDR-capable .”
For Imagine Communications , the company has developed a hybrid multiviewer solution — EPIC MV . Designed to simplify monitoring environments as media companies migrate to IP , the EPIC MV software-based solution natively supports uncompressed content , as well as compressed streaming formats , including MPEG-2 and AVC / H . 264 . Option boards provide for SMPTE ST 2022-6 / 7 and ST 2110 reception , baseband 3G / HD / SD reception , as well as SMPTE ST 2022-6 / 7 HD mosaic transmission .

Achieving highest resolution images with essential tools
Having deployed Postium ’ s OBM-U series broadcast monitors for the 4K / UHD broadcasting of the 2018 Winter Olympic Games , South Korean broadcaster KBS has moved the displays to its 4K / UHD control room after the conclusion of the tournament .
Another user of Postium ’ s broadcast monitors is Studio Berlin , a live TV production provider based in Germany , who has added a 4K / UHD outside broadcast ( OB ) van to its fleet of mobile production resources . Commissioned by systems integrator Broadcast Solutions , the OB van is equipped with five Postium OBM-U240s for video engineering . Postium has additionally supplied another two OBM-U310s to Broadcast Solutions , which will be installed in the new 4K / UHD OB van .
Postium ’ s OBM-U series is integrated with support for 3G / 6G / 12G-SDI , and features wide colour gamut ( WCG ) as well as colour space and gamma comparison . Particularly for HDR display , the OBM-U series support PQ EOTF ( ST 2084 ), hybrid log gamma ( HLG ) and S-Log3 .
Poh added : “ At Postium , our first introductory broadcast monitor product , which was released two years ago , is designed based on 4K / UHD HDR and IP . Today , we have a full range of 4K / UHD and HDR monitors available in different sizes to support content producers ’ acquisition needs — from on-set monitoring to mastering , as well as editing and quality control .
“ Besides incorporating different types of inputs and formats , our monitors feature HDR waveform vector scope , adjustable false colour , and gamut error detection that are useful tools for producers ’ day-to-day production .”
Marc Ravard , product line manager for multiviewers , Imagine Communications : “ When media companies make the choice to start their transition to IP networking , they are also looking for monitoring solutions with native support for SMPTE ST 2022 and ST 2110 IP standards , as well as 4K / UHD resolution .”
multiviewers at Imagine Communications , says : “ Transition from SDI / baseband networks to IP networking is under way . IP networking is delivering on the promise for much more flexible and agile signal processing and monitoring . At the same time , production environments witness the increase of 4K / UHD productions .
“ When media companies make the choice to start their transition to IP networking , they are also looking for monitoring solutions with native support for SMPTE ST 2022 and ST 2110 IP standards , as well as 4K / UHD resolutions .”
With the installation of EPIC MV , media companies can deploy an SDI multiviewer solution using four EPIC-MV-3G input PCIe cards to monitor up to 48 PiPs through up to four HD mosaics . When progressively deploying IP signals , the EPIC MV architecture allows them to replace 3G cards with EPIC-MV-UCIP inputs cards that deliver ingest for SMPTE ST 2022 and ST 2110
System integration and beyond .

input sources while maintaining the high density of 48 PiPs over four HD displays .
And in the transition to 4K / UHD , the demand for 4K / UHD mosaic will also increase . In this circumstance , media companies can deploy EPIC MV to deliver four HD mosaics or one 4K / UHD raster with the same density of 48 PiPs made of mixed input signals .
Ravard explains : “ 4K / UHD monitoring can be delivered in many ways . When ingesting 4K / UHD content natively to the multiviewer , media companies need to invest in IP switches with four times the bandwidth capacity . High-quality 4K / UHD monitoring can be achieved by using a scaled-down version of the original signal .
“ For example , Imagine Communications ’ Selenio Network Processor ( SNP ) can deliver a high-quality HD proxy of a 4K / UHD signal to our EPIC MV multiviewer . This combined solution of processor and multiviewer optimises an IP infrastructure investment for 4K / UHD monitoring .”
Both EPIC MV and SNP are powered by Zenium , a cloud-native microservices platform that is designed to enhance how workflows and networks are architected , implemented and managed . As Imagine ’ s approach to technical adoption , this component-based architecture enables media companies to create custom solutions , adapt to market dynamics , and deploy new services .
