Biamp has added low-latency, 4K networked video distribution to the Tesira platform with the introduction of TesiraLUX, which transports both audio and video signals over a single network with AVB/TSN.
“With the addition of TesiraLUX, we have put the ‘V’ in ‘AVB,’ truly extending the power and sophistication of what is possible in a networked AV solution,” said Chris Fitzsimmons, product manager for video products at Biamp. “TesiraLUX delivers dependable performance and automatic handling of lip sync, resulting in transmissions that are visually lossless and perfectly aligned. It turns Tesira into a complete network media platform simplifies even the most complex AV applications in corporate, government, hospitality, and education.”
The TesiraLUX product line will initially include an AVB video encoder (TesiraLUX IDH-1) and an AVB video decoder (TesiraLUX OH-1). The encoder features one HDMI port, one DisplayPort interface, and two mic/line-level analogue inputs. The decoder includes one HDMI port and two line-level analogue outputs.
TesiraLUX supports video formats including 4096 x 2160 at 60Hz, HDR and the Rec. 2020 colour space. It can accept video at up to 16-bit colour depth with 4:4:4 chroma subsampling, and supports eight channels of embedded PCM audio, which can be broken out to be routed and processed independently. The system also manages EDID automatically between the TesiraLUX device and the input source/output display thanks to scalers in both the encoder and decoder.
By utilising AVB/TSN, TesiraLUX is claimed to produce a total system latency of less than two frames (33ms at 60Hz), including scaling, compression, and network transit. AVB/TSN bandwidth reservation capabilities coupled with TesiraLUX’s bandwidth management tools also set up customers to create converged networks rather than dedicated AV media distribution network infrastructure.
TesiraLUX solutions aid integrators on decisions about what to send over the network, which results in visually lossless transmissions that make best use of the available bandwidth. Multiple software-based options are available for managing bandwidth, including setting maximum resolution, frame rate, and rate of compression. With both a 1Gb (RJ-45) and a 10Gb (SFP+) media port available, designers have a wide range of transmission options from which to choose.
Within a single software environment, system designers can create audio and video installations to match their exact specifications. Designers can benefit from a modular and intuitive approach to system design and commissioning due to the TesiraLUX’s video partitions behaving like Tesira’s audio partitions, resulting in time and cost savings for integrators.
In addition, Tesira coordinates signal distribution so there’s no need to manually add audio delays for lip sync.
TesiraLUX will be available January 2017
