Tom Pavicic joins Vitec Production Solutions
The Vitec Group has appointed Tom Pavicic to its Production Solutions division as regional sales manager , Australia and New Zealand . Based in Sydney , Pavicic will be responsible for building and managing strategic channel partnerships , and further develop the sales organisation in the region . Pavicic was previously CEO of Quinto Communications , a company which he joined as general manager in 1997 . At Quinto , he managed operations in ANZ across three offices in Sydney , Melbourne and Auckland . Audrey Chang , channel and customs marketing director , Asia-Pacific , Video Production Solutions , added : “ That background [ at Quinto ] gives him valuable perspective as he works to reinforce our position in ANZ , and ensure we have a strong , committed network of resellers targeting all market sectors .”
SLR Magic has adapter for Fujinon MK lenses
SLR Magic has launched Anamorphot 1,33x-65 anamorphic adapter , compatible with Fujinon MK lenses . This new adapter accommodates lenses with a front element size of up to 65mm , and has a rear thread size of 82mm . The front thread allows the use of ‘ screw ’ in filters and diopters . SLR Magic optimised this new adapter for Fujinon ’ s MK range of zooms , namely the Fujinon MK 50-135mm T2.9 . According to Fujifilm , the adapter will mount directly onto the Fujinon zoom ; and when mounted on a Fujinon MK 50-135mm , the integration of the adapter to lens appears like a “ singular unit ”.

If TV is the centrepiece of the living room , then the multiviewer is the hub of every broadcast application , where a variety of different video sources and formats are all consolidated within a single display for monitoring and processing . Besides requiring different specifications for each application , multiviewers today are also marrying technologies like IP for greater scalability and flexibility . Josephine Tan writes more .
For every broadcast application — regardless in-studio or mobile — the largest piece of equipment installed within the infrastructure is the multiviewer display . Apart from its primary function of bringing together multiple video sources for display onto a single monitor , a multiviewer today has to manage increasingly complex workflows as media companies are delivering videos in many different formats — ranging from SD and HD to even higher resolution images like 4K / Ultra HD ( UHD ) and high dynamic range ( HDR ).
Multiviewer requirements differ from application to application , depending on the infrastructure , while taking into consideration factors such as future I / O expansion and redundancy levels . In a live production control unit or an outside broadcast ( OB ) truck , one key multiviewer aspect is speed . This is because operators need to be assured that the multiviewer displays the content with minimum latency , as they are transmitting and watching similar content with viewers at the same time .
Besides the issue on latency , other key requirements for multiviewers in a live production unit are video and audio alarms , as well as support for IP using SMPTE ST 2110 , and future-proofing for 4K / UHD and HDR , suggests Erling Hedkvist , senior vice-president of business development at Lawo .
He tells APB : “ The biggest impact is probably around 4K / UHD monitoring , which is due to the bandwidth requirements , and has been a very difficult topic to address . The biggest multiviewers available in the market are able to process 32 or 64 1080p signals . But in a 4K / UHD ecosystem , this equates to just eight sources , which does not make it a very useful monitoring solution .
“ In addition , with the clear trend to IP and SMPTE ST 2110 , multiviewers need to be able to support both IP and SDI sources . Therefore , media companies are looking for multiviewer solutions that can accept both SDI and IP sources , as well as managing 4K / UHD and HDR in a scalable way .”
In transmission and headend monitoring facilities , the key function for multi viewer is monitoring . This encompasses the capability of keeping track on issues such as audio , video and ancillary data , which may result in errors like black picture , low audio or loss of close captioning . In addition , operators in fixed facilities are monitoring uncompressed inputs from production studios , alongside materials stored on servers .
Lawo ’ s vm _ dmv64-4 is a virtual machine ( VM ) for the company ’ s V __ matrix IP routing and processing platform , and is designed based on a distributed architecture where multiple modules are able to network together .
“ In these fixed facilities , operators are also monitoring many different types of video formats ,” Hedkvist continues . “ From the uncompressed HD source , the transmission signal will go through multiple encode stages and land on multiple platforms . It is important for the operator to be able to monitor both the over-the-air , cable and over-the-top ( OTT ) streams at the same time , and have alarm systems for all .”
In April this year , Lawo introduced the vm _ dmv64-4 virtual module ( VM ) for its V __ matrix IP routing and processing platform , complementing the existing vm _ mv16-4 , vm _ mv18-4 and vm _ mv24- 4 multiviewer line-up . The vm _ dmv64-4 is designed based on a distributed architecture where multiple modules network together . These modules can be hosted together in the same V __ matrix frame , in different frames or even in different geographical locations .
According to Lawo , every vm _ dmv64- 4 has an input stage capable of receiving up to 24 sources of any combination of 4K / 3G / HD / SD , which is limited only by the physical or network I / O . These sources are downscaled by the vm _ dmv64-4 , and returned to the network as IP-encapsulated mipmaps .
Hedkvist explains : “ For instance , while a traditional multiviewer would be described as a blade that took perhaps 24 sources and generated four outputs , Lawo ’ s distributed multiviewer works by separating the input and output stages connecting to an IP network .
“ One input stage can process up to 24 sources or up to 40GbE , and the operator can simply add more processing blades linearly to manage more sources . And
