Television in Transition: Expanding Possibilities for Audio
Thursday, October 18, 2018
1:00 p.m. to 4:00 p.m.
The entire television consumption and distribution ecosystem is being transformed at breakneck speed. Ubiquitous and cheap wireless and broadband networking; smart TVs and mobile devices; and massively-scalable cloud computing are building a completely new entertainment distribution system practically overnight, upending the traditional broadcast model, and changing viewing habits forever. This transition from “hardwired” to “virtualized” distribution is expanding the possibilities for television audio innovation, further raising the bar on ultimate quality of premium viewing experiences, while presenting creative challenges in translating these experiences to an ever-widening range of devices.
“The rule book for television distribution is being completely re-written. The migration away from traditional broadcasting to IP delivery will continue to accelerate the uptake of advanced encoding solutions and sophisticated audio services. This transition creates new challenges in providing quality and consistency across an ever-widening range of device and environments. Please join the DTVAG for a discussion of these and other important television audio issues.”
~ Roger Charlesworth, Executive Director, DTV Audio Group
Forum topics will include:
The advent of affordable consumer 4K and HDR on TVs and other devices is transforming the home viewing experience. Combined with the story-telling power of premium episodic content, upscale home viewing is supplanting cinema as the ultimate Hollywood entertainment consumption experience. Audio has been front and center in this transition as more and more premium content becomes available in Dolby Atmos. Is this trend sustainable? How are broadcasters and others responding to the demand for premium audio content?
An important aspect of next-generation audio systems is the ability to virtualize surround presentations over a range of devices and environments. Consumers are already being offered increasingly sophisticated immersive-audio-capable soundbars and TV sets; what are the prospects for enhanced surround virtualization on headphones, earbuds and mobile devices?
Infrastructure and Workflow for Next-Generation Audio
Next-generation audio services greatly increase network operations payloads with additional immersive channels, alternate languages, accessibility features, and all their attendant metadata. Can linear routing systems keep up with these demands or is SMPTE ST 2110 IP media infrastructure arriving just in time to save the day? If so, where are we on the attendant standards and operating protocols to make next-gen audio work in the IP domain? We will debate the issue and take an expert look at the standards crafting work going on behind the scenes.
The Wireless Spectrum Crunch Marches On
Carriers are quickly rolling out services in their newly-acquired 600 MHz blocs making life difficult for wireless mics and other low-power users in many parts of the country. As the rollout in open blocks continues, stations are beginning to exit their existing allocations and head for new frequencies in an already over-crowded 500 MHz TV band. What is the long-term feasibility of operating in what remains of the UHF TV band, and are there practical alternatives on the horizon?
