✔✔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. - ✔✔Up to 4Kp60
✔✔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. 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. - ✔✔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). - ✔✔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.) - ✔✔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. - ✔✔A single Clock Leader on the network is able to keep
all followers synchronised, regardless of their sample-rates or frame-rates.
✔✔JPEG2000 codecs process 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 several frames. - ✔✔The JPEG2000 codec is an
intraframe codec capturing each frame individually.
✔✔Which IP Range is not designated for use on a local network? - ✔✔8.8.__.__
✔✔Many Dante products will provide a Dante port and "Manufacturer Control" port that
is totally separate. The separate port might be used to remote control a mixer, program
a DSP, or steer a PTZ camera.
, How do you set the IP address for the manufacturer's control port? - ✔✔Read the
instruction manual for the product. Setting the manufacturer's control port is unrelated to
Dante, and thus it can be different for each product line.
✔✔On a network switch, any cable can plug in anywhere. However, a best practice for
cable management is to start
-from the first port working your way up and
- from the last port working your way backwards. - ✔✔network endpoints, trunk lines
✔✔If a device has obtained an IP address using Link Local, which IP configuration
would be within its subnet - ✔✔IP Address: 169.254.189.23 Subnet Mask: 255.255.0.0
✔✔Neutrik etherCON ports must be populated by Neutrik etherCON cables. - ✔✔The
Neutrik etherCON port provides an RJ45 at the center and thus it does accept standard
Ethernet cables.
✔✔What IP addressing methods are available for Dante devices? (Select all that apply.)
- ✔✔DHCP Dynamic Host Configuration Protocol
Link Local
Static IP Addressing
✔✔Which statements are true about Dante and switches to connect them? (Select two.)
- ✔✔Some Dante devices can daisy-chain, allowing small systems to run without the
need for an external network switch.
Unmanaged switches may be fine for small systems.
✔✔Many Dante products will provide a Dante port and "Manufacturer Control" port that
is totally separate. The separate port might be used to remote control a mixer, program
a DSP, or steer a PTZ camera.
When this manufacturer control port is provided, it is sometimes exposed on its own
network connection, sometimes it is merged with an internal network switch so it
appears through the Dante Primary port. - ✔✔True
False
✔✔Which of these are network topology methods were discussed for connecting Dante
and Dante AV devices? (Select two.) - ✔✔star
spiral
daisy chain (also known as switched)
hook and ladder
✔✔When using category cable, what type is recommended? - ✔✔CAT5e or better.
✔✔When choosing a network switch, what minimum speed is suggested? - ✔✔1 Gbit
