DANTE LEVEL 1 STUDY GUIDE UPDATED STUDY
QUESTIONS AND ANSWERS GRADED A+
✔✔Luma - ✔✔Encoded brightness information
✔✔Chroma - ✔✔Encoded color information
✔✔What does the first number in the encoding description represent? (ex. 4:2:2) -
✔✔The number of pixels in a row with their own luma (brightness information)
Luma will always read brightness information for all pixels in a row, so the first number
will always be 4
✔✔What is the first number in the encoding description? - ✔✔4
4:4:4, 4:2:2, 4:2:0
✔✔What does the middle number in the encoding description represent? (ex. 4:4:4) -
✔✔The number of pixels in the first row with their own chroma (color information)
✔✔What does the third number in the encoding description represent? (ex. 4:2:0) -
✔✔The number of pixels in the second row with their own chroma (color information)
✔✔What does HDR stand for and mean? - ✔✔High Dynamic Range
Captures a wider range of highlights and shadows
✔✔Frame rate for film - ✔✔24 fps or 48 fps
✔✔Frame rate for TV (PAL) - ✔✔25 fps or 50 fps
✔✔Frame rate for TV (NTSC) - ✔✔29.97 fps or 59.94 fps
✔✔What is the JPEG 2000 codec? - ✔✔The encoding and decoding system used by
Dante AV to compress and decompress data
Provides visually lossless video quality
✔✔Does JPEG 2000 codec have generational loss (loss of data from encoding and
decoding process)? - ✔✔No
Technically, there is a visually imperceivable loss after the first generation
✔✔Intra-frame Codec - ✔✔Encodes one frame at a time (JPEG 2000)
,Low latency
Contains errors to 1 frame
✔✔Inter-frame Codec - ✔✔Encodes frames in groups (MPEG)
Medium latency
Errors continue until next key frame
✔✔High-Bandwidth Digital Content Protection (HDCP) - ✔✔Protects (locks) copyrighted
material in transport between devices
Common for DVD, Blu-Ray, Cable/Satellite TV, Computer video out, etc.
✔✔How many video devices does Dante allow with HDCP protection? - ✔✔Allows up to
16 devices participating with the video path
✔✔Resolution - ✔✔The number of pixels in each dimension
✔✔Aspect - ✔✔How wide the image is, relating width to height
✔✔Dante AV supports color space in - ✔✔4:4:4, 4:2:2 , and 4:2:0
✔✔Maximum video resolution for Dante - ✔✔4K/60 resolution
✔✔Is Dante audio compressed? - ✔✔No
✔✔Daisy Chain / Switch Mode (Network Topology) - ✔✔Two external ports and an
internal Dante connection all link through an internal network switch
If one computer fails all connections are affected, and if the switch fails all connections
are affected
✔✔Star Mode (Network Topology) - ✔✔All Dante devices connected to a central switch
If one device fails no others are affected, but if the switch fails all connections are
affected
✔✔Trunk Line / Uplink - ✔✔When multiple switches are linked together
✔✔Where are Endpoints (computers, audio devices, etc.) generally plugged into
switches? - ✔✔Starting at port 1 and moving up from there
, ✔✔Where are Trunk Lines / Uplinks generally plugged into switches? - ✔✔Starting at
the last port and moving their way back
✔✔Redundant Mode (Network Topology) - ✔✔The second external port connects to an
independent internal Dante port with its own IP address
Each port runs as an independent network
Devices can be routed to both networks (redundantly) as a backup
✔✔Network Topology options - ✔✔Daisy Chain, Star, and Redundant
✔✔Control Port - ✔✔Can be used to control or program a DSP, remotely control a
mixer from an iPad, adjust settings on a beam forming mic, etc.
✔✔How do you access control functions? - ✔✔Control may be offered as either
Discrete (independent control port) or Combined Port (merged into primary Dante
connection port)
✔✔How do you make a mass diagonal link in Dante controller? - ✔✔Control click
✔✔How do you break a mass diagonal link in Dante controller? - ✔✔Shift Control click
✔✔What does a red circle with a slash indicate in Dante controller? - ✔✔The device can
be seen, but there is something wrong with the link (mismatched sample rates, etc.)
✔✔What does a yellow triangle with an exclamation point indicate in Dante controller? -
✔✔The receiver device can't find the source device on the network
Source device may not be powered on
✔✔Which window will show you all devices at once? - ✔✔Network View
✔✔Which window will show you settings for an individual device? - ✔✔Device View
✔✔Are Dante devices reliant on IP addresses to recognize each other? - ✔✔No
Dante receivers recognize the name of the Dante transmitter and the name of the
channels
It is best practice to name devices before making subscriptions
✔✔Latency - ✔✔The amount of time it takes for a process to complete
