Of course, because computers tie together and control most broadcast facilities today, they must be networked in the facility as well. All codecs present in the modules are available for frame-accurate back-to-back playout. The modules support up to 16 channels of embedded audio - fully supporting even the most demanding multi-language broadcasting requirements.Ĭodec support on MediaPort 7000 units include SD/HD MPEG-2, SD DV (DV 25, DVCPRO 25, DVCPRO 50), DVCPRO HD, XDCAM HD, ProRes 422, AVC-Intra (Class 50 and Class 100) and VC-3 (SMPTE 2019-1). MediaPort modules accurately capture and replay all information contained in the video stream - including VBI and VANC. When expansion is needed, additional MediaPort 7000 modules can be added without taking down the system. The modules attach in manageable increments so that Spectrum systems can be configured to meet exact requirements for channel count and video compression formats. It provides a modular platform for growth and quick change as well, simplifying playout workflows with channel-in-a-box solutions. Larger facilities can bridge an existing SDI plant with HD and file-based technologies.Īnother company with its own take on broadcast infrastructure is Harmonic, with its Spectrum Media Server Solutions. Bridges can be built between the two generations of equipment while preserving the best image quality possible. For example, a small broadcast station can upgrade to a digital switcher while still using analog studio cameras. The integrated intelligence in the design of such a system provide major benefits and flexibility for broadcasters at all stages in a period of constant change. They include format conversion, fiber interfacing, audio processing, loudness monitoring, signal path protection, intelligent monitoring and quality control, synchronizers, distribution amplifiers and routers - all capable of operating at any resolution and with the flexibility of being used in multiple ways and configurations. There are currently over 250,000 Snell modules in service globally. Turner Broadcasting System in Atlanta runs on more than 7,000 Snell IQ Modules supplying more than 30 channels around the world. With over 400 modules now in production, complex systems can be put together and altered quickly. Snell’s automated control and monitoring systems keeps them all running with minimal operator intervention. With a set of smart infrastructure building blocks, engineers can build bridges between different generations of broadcast equipment and adapt quickly to an ever-changing palette of new requirements and services.Īn early leader in this area was Snell with its IQ Modular line of plug-and-play components. The modules made up a smart, flexible and centrally controlled infrastructure.īy “smart,” I mean a computer-controlled infrastructure that automatically configures new modules as they are plugged in. So a building block approach was begun that allowed broadcasters to purchase plug-and-play modules that would work together. All the components in the broadcast plant, which had to operate simultaneously and without image degradation, needed to be easier to assemble and customized for each unique facility. Broadcast facilities began to take on a very different look after the analog era. Not only that, when computers took over control of such facilities, a second infrastructure of computer network components had to be overlaid with the broadcast infrastructure. Facilities were suddenly faced with a collection of analog, digital and file-based islands of equipment that had to be interconnected and work flawlessly together. As television studios began moving from analog to digital technology, building the broadcast infrastructure became far more complex.
