The advent of 4k cameras changed the game, but there’s currently no SMPTE standard for 4k so it’s like the wild west out there when it comes to 4k.
A 4K technology solution, involving both Sony and Miranda, was on show at NAB and will soon be integrated in a 4k-equipped OB truck belonging to UK company Telegenic. The truck, described as a European first, is expected to go into service later this year.
The Telegenic truck will be capable of capturing live footage in HD or 4K, supporting two unique formats out of the same truck and is underpinned by Sony’s existing product portfolio including HDC-2500R cameras, PMW-F55 4K cameras, Sony’s MVS-8000X Vision Mixer, Miranda’s 4K / UHDTV enhanced NVISION 8500 Series Routers, and three Sony PVM-300 4K LCD monitors, to deliver a reliable 4K production workflow.
Miranda jumps into the 4k fray
Miranda was keen to show it's playing a central role in the 4k/UHDTV transition this year, by showcasing technology that is already capable of supporting the 4k production environment. In particular to capture and edit action, particularly sports, at full resolution.
Miranda’s 4K / UHDTV NAB demos were spearheaded by the new Telecast CopperHead 3404K camera-mountable transceiver, which requires just two strands of lightweight fibre optic cable to carry all bi-directional signals needed, including four 3Gb/s HD/SDI paths, for 4K productions from a camera to a truck or control room. This enables 4K / UHDTV ENG cameras to be dual-purposed for use in studios, ENG and digital cinematography without the copper cabling limitations imposed on HD and now 4K.
Also on show were Miranda routers such as the 4K / UHDTV enhanced NVISION 8500 Series, optimised with SMPTE RP-168-compliant, quad-link 3 Gb/s switching that provides synchronised switching of all 4K links during the same vertical interval.
For monitoring, Miranda solutions readily handle 4K and downconverts standard HD so that standard HD/3Gb/s multiviewers can be used for monitoring while 4K images can be integrated into a standard HD broadcast. Additionally, the new Kaleido-Modular-X multiviewer enables broadcasters to use 4K features to maintain video and graphics quality.
“The advent of 4k cameras changed the game, but there’s currently no SMPTE standard for 4k so it’s like the wild west out there when it comes to 4k,” said Scott Murray, Miranda’s senior VP of core products during the Miranda press launch. “Miranda’s products allow 4k production from acquisition through routing, monitoring and down conversion. UHDTV trade show demos are transforming speculative conversations into informed decisions about physically making the transition to higher quality.”
