Supporting SDI and IP Infrastructures
OB trucks and Remote Production
In a fast-paced OB environment, it is essential that operators have reliable, flexible tools that fit seamlessly in to the production process that monitor feeds to ensure that they meet the correct channel assignment; can check the integrity of the different mixes; monitor the multi-channel stems of media cut for playback; have back-up in the unlikely event that the main mixer should fail; check video and audio circuits within the racks area and at the tailboard or to monitor prehear and comms within the production environment.
Satellite News Gathering
In a Newsroom that produces fast turnaround 24 hour news, audio products can be used to monitor the audio for level and technical compliance in production and the racks room; to monitor presenters prehear and comms circuits; or ensure loud and clear location reports from the field.
A typical Broadcast TV production workflow often demands that operators have the ability to hear audio from diverse sources such as routers, VTR/Servers, Talent, and communications. The format of incoming audio signals may vary considerably from SDI embedded to AES and analogue with channel configurations in surround sound, stereo, mono, with multiple languages, clean FX channels and multiple programme mixes further complicating the situation. When signals vary dynamically during production, or setups alter completely from show to show, programme makers need audio monitoring which can adapt and is simple to use.
Master Control, Ingest and QC
MasterControl is the most technically complex area of a broadcast facility. The main monitoring in MCR requires features like downmixing, the Assign Matrix, Loudness measurement and Audio Delay for checking Lip Sync, a comprehensive toolbox for analysing whichever audio format enters or exits the facility and the ability to connect an external screen ensures that operators have precise visual feedback as part of their monitor stack; whilst QC and Ingest check and log loudness levels of the outgoing audio content.
Playout and Transmission
Playout Technicians use audio monitors to listen to the outputs through their full range loudspeaker system, whilst in the Transmission area a unit allows the operators to conducts a final check.
Addressing the challenges of IP for audio
With customers now realising the benefits of IP infrastructures using SMPTE 2022-6 and the soon to be ratified SMPTE 2110, what does this mean for those needing to manage and monitor audio?
A key challenge for any audio solution is to create and present an operational experience that is both simple and intuitive, regardless of the method being used to carry audio throughout a broadcast facility. The transition to IP infrastructures, coupled with the need to do more with less, only serves to increase the importance of being able to address this challenge.
At the very least, operators needing to manage and monitor audio within an IP infrastructure, need a set of quick and easy to use controls that:
- are made available by a friendly and intuitive control interface
- will allow them to monitor and manipulate audio in the same manner that they have grown used to when working in traditional SDI environments
