Abstract:
A recently completed refresh of American Public Media’s Marketplace studios is focused on real-time collaboration via IP based signal distribution for audio, display, and control. Legacy analog and digital cabling has been replaced by a multicast IP focused IT infrastructure connecting the main Los Angeles studios to APM’s New York and Washington DC bureaus. Marketplace Morning Report and Marketplace Money are both hosted from New York but produced, directed, and engineered from the control rooms in Los Angeles. This workshop will explore how audio over IP enables real time collaboration across locations for live broadcast.
Our three presenters will discuss
· The business case for this major investment and its impact on work flow and the user experience from the host, director and producers’ perspective.
· The audio technologies employed and systems design from an audio signal routing and control perspective
· The underlying IT infrastructure which supports all this and how off-the-shelf network equipment is configured to support multicast distribution and provide transmission redundancy
