BrightEye NXT 450 Clean Streaming Router
Installation, Configuration and Operations Guide
To Configure the TSG Slate Text
Enter the desired Slate text in this field, then hit the Tab key or click outside of the Slate Text field. As
with all of the configuration settings in the Router, this will be saved in non-volatile memory so that
it persists when the Router is powered down. The text entered in this field is not lost when the Slate
Enable is turned off.
To Configure the TSG Cyclops
In order to produce a dynamic, constantly changing Test Pattern, enable one of the Cyclops modes to
affect the picture, sound or both. The Cyclops feature adds a motion element which is overlaid over
the test pattern video. It is located below the Slate field. The white cyclops pulse continuously sweeps
horizontally back and forth in its black window. At the left and right extremes of its excursion the pulse
makes a one frame bright flash.
To Configure the TSG Slate
When on, the text which has been entered in the Slate Text field will appear over top of the test
pattern.
Meanwhile, the Beep/Pop feature will add variety to the tones carried
by the embedded audio. Selecting Beep will produce a short beep (and
is otherwise silent), while Pop momentarily takes the selected tone to
silence. Industry practice identifies odd numbered channels as carrying
Left content, and even numbered channels as the Right half of a stereo
program. The Pop and Beep timing in the audio follows this convention,
with the odd channels being marked when the Cyclops makes its left
flash, and the even channels marked when the right edge flash occurs.
Further, the ‘left’ channel is a single Beep/Pop, while the ‘right’ channel is a double Beep/Pop. This
allows left/right identification even after the audio has been disembedded (demultiplexed) and has
lost the implied channel association.
These aural and visual markers provide proof at downstream points in a transmission chain that it
is producing live, uninterrupted delivery of content – even when not in active service. The precise
synchronization between the visual Cyclops and the aural Beep/Pop are also useful to verify sound/
picture lip-sync.
