Dante Certification Final Exam/53Questions with Solutions
STUDY GUIDE 1 - -
-On a Dante network, there must be a different clock leader for each sample
rate on the network. - -False. One Clock Master will provide synchronization
to all Dante devices, regardless of their individual sample-rates or frame
rates..
-An audio subscription (connection) can be established between two Dante
interfaces operating at different bit depths. - -True. Like most digital audio
devices, Dante devices will usually be able to add missing bits or truncate
extraneous bits to match the expected internal operation.
-The sample rate of an audio system
dictates: - -the audio resolution in time. According to the Nyquist Theorem,
the sample rate must be at least twice the highest audio frequency to be
captured.
-The bit depth of an audio system
dictates: - -the resolution of the audio signal's amplitude. A greater bit depth
increases dynamic range.
-A Dante audio subscription (connection) can be established between two
Dante interfaces operating at different audio sample rates - -False. Each
Dante interface can only operate at one sample rate at a time. If a sample
rate converter is employed, it will sit behind the Dante network port.
-Dante audio is sent: - -Uncompressed, bit-perfect.
-What audio sample rates are supported by Dante? - -Dante supports most
common sample rates from 44.1kHz to 192kHz.
-If we increase the sample rate of a device from 48KHz to 96KHz, what is the
impact to the network? - -A 96kHz subscription will require (roughly) twice
as much bandwidth as a 48kHz subscription.
-Roughly how many channels of 24-bit, 48kHz audio can be carried on a 1
Gbps connection? - -512x512
-A 1Gbps network switch can manage more Dante channels than a single
1Gbps link can. - -True. A non-blocking network switch will be able to handle
the total of all ports capacity at all times.

-Dante AV can support multiple
codecs. However, the initial products
will transport video in what format? - -Compressed using a visually lossless
JPEG2000 codec.
-The JPEG 2000 codec initially included in the Dante AV module is used in
65% of digital cinema rooms today. It is visually lossless,
supporting both video and computer graphics (like spreadsheets and slide
presentations). - -True. The JPEG2000 offers sharp quality and intense colour
definition with a visual accuracy adopted by most professional uses.
-Dante AV devices sends and receives audio uncompressed so it is
completely compatible with Dante audio devices. - -True. As audio and video
are transported separately as independent essences, it is possible for a
Dante AV device to send its audio channels to a Dante Audio device and
vice-versa.
-Interlaced video draws all the odd lines, then all the even lines. This creates
two "fields" for each frame. - -TRUE. The interlaced signal contains two fields
of a video frame captured consecutively. This enhances motion perception to
the viewer, and reduces flicker.
-Dante AV devices have a scaler in it.
What does the scaler affect? - -The scaler can adapt screen resolution. (i.e. -
it can scale a 4K source to 1080p for display)
-Which answer best describes the JPEG2000 encoding process? - -There is a
"visually lossless" impact on the first encoding, but JPEG 2000 can decode
and encode over and over with no further loss.
-In Dante AV, with the JPEG2000 codec
and a 1 Gbps connection, what
resolution and frame rates are
currently supported? - -Up to 4K (4096 x 2160) at 60fps
-The JPEG 2000 codec commonly
used in Dante AV processes video
frames in groups. If a packet is
corrupted, the picture will
automatically recover when the
current group of frames ends and the
next keyframe arrives. It could be
