Comprehensive Questions
(Frequently Tested) with
Verified Answers.
On a Dante network, there must be a different clock leader for each sample rate on the network. -
Answer: 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. - Answer: 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: - Answer: 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: - Answer: 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 - Answer: 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: - Answer: Uncompressed, bit-perfect.
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.
Roughly how many channels of 24-bit, 48kHz audio can be carried on a 1 Gbps connection? - Answer:
512x512
A 1Gbps network switch can manage more Dante channels than a single 1Gbps link can. - Answer: True.
A non-blocking network switch will be able to handle the total of all ports capacity at all times.
STUDY GUIDE 2 - Answer:
Dante AV can support multiple
codecs. However, the initial products
will transport video in what format? - Answer: 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). - Answer:
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. - Answer: 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.
- Answer: 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? - Answer: The scaler can adapt screen resolution. (i.e. - it can scale a 4K
source to 1080p for display)
