Panasonic demonstrated its new AW-UE150 PTZ 4K-UHD/2K-HD camera. Designed for studio operation, this has a large MOS sensor, a 75.1 degree viewing angle and 20x optical zoom. Outputs include 4K 50p 12G-SDI, HDMI, optical fibre and IP.
Samsung showed its latest QLED 8K Signage high-brightness display which used AI-enhanced upscaling. The new display at less than 4 cm deep and uses a combination or local dimming and 'Quantum Light Control'. Samsung also promoted the open-standard HDR10+ protocol which it developed in cooperation with Amazon. HDR10+ uses dynamic metadata to adjust brightness levels on a scene-by-scene or frame-by-frame basis.
Zoom demonstrated its LiveTrakL-20 digital audio mixer/recorder, capable of recording 22 audio tracks simultaneously. Features include 20 mixing channels (16 mono plus 2 stereo) with XLR and 1/4-inch connectivity, 20-track simultaneous playback, 48 volt phantom power on each input, a pre-record function and automatic recording start/stop. A 12-input version with 14-track simultaneous recording (Model L-12) is also available. Both models record to SD card and include USB 2.0 import/export ports.
One of the highlights of the parallel NAB conference was a paper by Olie Baumann of Mediakind on the subject of live 360 degree surround video delivery:
"360 degree video leverages much of the technology developed for VR gaming but differs in the way it is generated and delivered. Specifically, 360 degree video capture, delivery and rendering can be performed live, allowing operators to give consumers the sense of being at a sporting or live music event. With creative camera placement and production, the end user can have an experience that would not be possible even with a ticket. We have experimented with 360 degree cameras mounted on the car for motorsport events and mounted immediately behind the basket at a basketball game, allowing the viewer a unique perspective on the event."
"In order to deliver a high quality video experience, the resolution of the 360 degree image needs to be very high by current broadcast standards. An HD resolution headset or phone will display a small section of the entire video known as the viewport. To ensure that the full 360 degree image does not limit the displayed resolution it must have a resolution of at least 8K × 4K or the equivalent of sixteen HD broadcast videos."
"We need to be able to deliver it to mobile devices such as phones and tablets which, at the time of writing, don’t have real-time 8K decoders on board. The use of a tile-based streaming solution has many advantages. Not only does it meet the bandwidth and decoder requirements necessary to allow consumption on mobile devices but it also lends itself to cost effective encoding on cloud platforms. This in turn means that the encode can be elastically scaled to handle any resolution, frame rate and number of channels which will surely be necessary to keep up with advances in display and head mounted device technology."
Quite a challenge and certainly a technology to keep an eye on.
