esiraLUX allows you to make intelligent decisions about what to send over the network, and helps you treat content types appropriately (see Do You Always Need 4K?), resulting in visually lossless transmissions. There’s a lot going on under the hood to make that happen, though, so let’s go through each method of controlling bandwidth in TesiraLUX.

Maximum Resolution
If your output displays are all 1920 x 1080, there’s no reason to send full 4K over the network, right? Set the maximum (usable) resolution required by your displays — the broadcast-quality scaler in our listeners will manage the EDID handshake automatically for lower resolution displays so that you don’t have to. Remember, even if your displays support 4K, you have to consider the viewers’ distance from the screen and manage resolution appropriately.

Minimum Frame Rate
Typically, you wouldn’t change the frame rate for motion images, but synthetic (computer) images are a potential candidate for removing frames from the stream. If your network bandwidth target is s till over limit once you set the max resolution, then content like presentations, spreadsheets, schematics, and the like are good candidates for reducing frame rates. Since the content is mostly static, the viewing experience won’t be greatly impacted.

Compression Ratio
Compression refers to transmitting an image using fewer bits than the original representation, typically by identifying and removing unnecessary information; it’s what allows us to fit oversized data onto a network link. Excessive compression may introduce artifacts, which can include blocking, ringing, blurring, solarization, posterization, and mosquito noise.

But Wait, There’s More!
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. You’ll also have the option of creating presets for your bandwidth settings, and the software will even indicate when a stream may be too large for TesiraLUX’s media port’s capacity.

All of these features are just for starters — we’re planning to expand our management capabilities down the road. Keep checking our blog for more insights and tutorials on all of Biamp’s products.
