ANSWERS | VERIFIED
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.
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.
- Answer-The JPEG2000 codec is an intraframe codec capturing each
frame individually.
Which IP Range is not designated for use on a local network? - Answer-
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? -
Answer-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
