Exam/53 Questions with
Solutions
STUDY GUIDE 1<<<<ANSWER>>>>
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..
In Dante AV, with the JPEG2000 codec
and a 1 Gbps connection, what
resolution and frame rates are
currently supported?<<<<ANSWER>>>>Up to 4K (4096 x 2160) at 60fps
The JPEG 2000 codec commonly
used in Dante AV processes 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>>>>False. The JPEG2000 codec is the best example
of intraframe encoding, applying a compression algorithm to each frame captured
individually, not built up from multiple frames, so they can be compressed and
transmitted out quickly to reduce latency.
On a Dante network, a single clock leader is established to manage all audio
sample rates and video frame rates.<<<<ANSWER>>>>True. A single Clock Leader
on the network is able to keep all followers synchronised, regardless of their
sample-rates or frame-rates.
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)
STUDY GUIDE 3<<<<ANSWER>>>>
When using category cable, what type is recommended?<<<<ANSWER>>>>CAT5e
or better is recommended.
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.
