In this fourth installment of the Immersive Audio series we investigate the production tools needed to produce live immersive content. Moving from channel-based output to object audio presents some interesting challenges as the complex audio image moves around in three-dimensional space.
Live sports productions are the natural home for HDR. The increase in luminance latitude combined with extended color space delivers an immersive experience never before witnessed by the home viewer. But backwards compatibility must still be maintained for legacy SDR audiences.
A major development has happened in the broadcast industry with the adoption of software running on COTS servers for processing uncompressed real-time video. Up to recently, this had not even appeared on the radar, but new technology evolution and innovation has now made software COTS for broadcasters a reality.
Broadcasters continue to see the benefits of IP and many are integrating piecemeal to build hybrid SDI-IP systems. At a first glance, monitoring of hybrid systems may seem to be just an extension of existing practices. However, the complex interaction of SDI and IP signal levels, buffers, and timing conspire…
Immersive audio transforms the listening environment to deliver a mesmerizing and captivating experience for a wide range of audiences and expansive group of genres.
As broadcasters accelerate IP migration, we must move from a position of theory to that of practical application. Hybrid solutions to integrate SDI, AES, MADI, and IP will be needed for many years to come, even with green field sites, as broadcasters seek a steady and methodical transition.
OTT distribution is worlds apart from traditional unidirectional broadcasting in terms of its fundamental operation and viewing preferences.
The internet is a rapidly expanding collection of service providers, many in direct competition, transferring broadcaster video and audio streams alongside many other types of often conflicting data.
Immersive audio has the great potential to transform our human listening experience, captivate our imagination, and inspire our inventiveness.
Moving to IP opens a whole plethora of options for broadcasters. Engineers often speak of the advantages of scalability and flexibility in IP systems. But IP systems take on many flavors, from on-prem to off-prem, private and public cloud. And then there is virtualization.
Part one of this four-part series introduces immersive audio, the terminology used, the standards adopted, and the key principles that make it work.
