Audinate Dante Level 1 UPDATED Actual
Exam Questions and CORRECT Answers
On a Dante Network, there must be a different clock leader for each sample rate on the
network. - CORRECT ANSWER- ✔✔One clock leader will provide synchronization to all
Dante devices, regardless of their individual sample rates or frame rates
A 1Gbps network switch can manage more Dante channels than a single 1Gbps link can? -
CORRECT ANSWER- ✔✔A nonblocking network switch will be able to handle the total of
all ports capacity at all times.
An audio subscription (connection) can be established between two Dante interfaces
operating at different bit depths. - CORRECT ANSWER- ✔✔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.
A Dante audio subscription (connection) can be established between two Dante interfaces
operating at different audio sample rates. - CORRECT ANSWER- ✔✔Each Dante interface
can only operate at one sample rate at a time.
What audio sample rates are supported by Dante? - CORRECT ANSWER- ✔✔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? - CORRECT ANSWER- ✔✔A 96kHz subscription will require (roughly) twice as
much bandwidth as a 48kHz subscription.
The bit depth of an audio system dictates: - CORRECT ANSWER- ✔✔the resolution of the
audio signals amplitude. A greater bit depth increases dynamic range.
The sample rate of an audio system dictates: - CORRECT ANSWER- ✔✔the audii resolution
in time. According to the Nyquist Theorem, the sample rate must be at least twice the highest
audio frequency to be captured.
Dante audio is sent: - CORRECT ANSWER- ✔✔uncompressed, bit-perfect.
, Roughy how many channels of 24-bit,48kHz audio can be carried on a 1Gbps connection? -
CORRECT ANSWER- ✔✔512x512
Dante AV devices send and receive uncompressed audio and is completely compatible with
Dante audio devices - CORRECT ANSWER- ✔✔Dante AV devices transport audio and
video in separate essences so it is possible for a Dante AV device to send its audio channels to
a Dante Audio device and vice-versa
Dante AV is available in a variety of video codecs. What video codec is used by "Dante AV
Ultra" that was discussed in this class? - CORRECT ANSWER- ✔✔Compressed using a
visually lossless JPEG2000 codec.
Dante AV Ultra uses a JPEG2000 video codec and a 1Gbps connection. What is its maximum
supported resolution(s) and frame rate(s)?
Expressions here are shown in resolution, interlaced/progressive, framerate. For example,
1080p30 means 1920x1080, progressive, 30fps. - CORRECT ANSWER- ✔✔Up to 4Kp60
Dante AV devices have a scaler in it. What does the scaler affect? - CORRECT ANSWER-
✔✔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? - CORRECT ANSWER-
✔✔There is a "visually lossless" impact on the first encoding. Further encode/decode
processes will experience no further loss.
Interlaced video draws all the odd lines, then all the even lines. This creates two "fields" for
each frame. - CORRECT ANSWER- ✔✔The interlaced signal contains two fields of a video
frame captured consecutively. This enhances motion perception to the viewer, and reduces
flicker.
JPEG2000 codecs are used in digital cinema rooms today. It is visually lossless, providing
excellent results for both video and computer graphics (like spreadsheets and slide
presentations). - CORRECT ANSWER- ✔✔The JPEG2000 offers sharp quality and intense
colour definition with a visual accuracy. It is well-adopted in professional use cases.
