Audinate Dante Level 1 | Questions with 100%
Correct Answers | Latest Update | Verified
What audio sample rates are supported by Dante? - 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? - ANSWER -A 96kHz subscription will require (roughly)
twice as much bandwidth as a 48kHz subscription.
The bit depth of an audio system dictates: - ANSWER -the resolution of the audio
signals amplitude. A greater bit depth increases dynamic range.
The sample rate of an audio system dictates: - 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: - ANSWER -uncompressed, bit-perfect.
Roughy how many channels of 24-bit,48kHz audio can be carried on a 1Gbps
connection? - ANSWER -512x512
Dante AV devices send and receive uncompressed audio and is completely
compatible with Dante audio devices - 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? - 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. - ANSWER -Up to
4Kp60
Dante AV devices have a scaler in it. What does the scaler affect? - 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? - 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. - 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). - ANSWER -The JPEG2000 offers sharp quality and
intense colour definition with a visual accuracy. It is well-adopted in professional
use cases.
What factors significantly affect the overall bandwidth demands of a compressed
video flow? (Select all that apply.) - ANSWER -The video frame resolution (i.e. -
1080p vs 4K)
The chroma sampling (i.e. - 4:4:4 vs 4:2:0)
The frame rate (ie 24fps vs 60fps)
On a Dante network, a single clock leader is established to manage all audio
sample rates and video frame rates. - ANSWER -A single Clock Leader on the
network is able to keep all followers synchronised, regardless of their sample-rates
or frame-rates.
