AptoVision will introduce Plethora at ISE. Plethora claims to be the first fully in-line engine for high fidelity processing of uncompressed audio and video signals across the network. AptoVision says that Plethora provides broadcast-quality scaling, color space conversion, frame rate conversion and several new audio functions including audio embedding and de-embedding.
Available on its BlueRiver NT+ and new BlueRiver 400 chipsets, the Plethora engine is named for the numerous functions it integrates into a single, in-line, zero-frame latency signal processing subsystem. These functions include broadcast-quality scaling, visually “indistinguishable” light compression (described below), color space conversion, frame rate conversion, audio embedding/de-embedding, audio down-mixing and audio re-sampling.
Optimized for video, graphics and text quality, the Plethora engine supports both upscaling and downscaling of motion video, graphics and text for resolutions up to true 4K/60/4:4:4. Applications include video-wall, multi-view and true seamless switching between sources of different resolutions.
Mathematically lossless for most content, this 1.4:1 ratio compression codec delivers images that AptoVision says are virtually indistinguishable from the uncompressed image. While almost all resolutions can be supported in uncompressed mode, this feature is most useful when small bandwidth savings are needed to deliver a unique resolution within a limited bandwidth envelope.
Analog or digital audio from any transmitter can be embedded into the HDMI output of any receiver on the same AV network. Conversely, digital audio from any transmitter can be de-embedded and sent to any receiver in its native format or down-mixed from LPCM to two-channel audio.
More details on Plethora will be available on the website after ISE.
