channels
Think of a channel as a ‘virtual transmitter’. It is virtual because the video, audio and
USB streams of a channel do not necessarily have to originate from the same physical
transmitter unit, although in most cases they will. For instance, you could arrange for
video and USB streams to be received from one host computer, while the audio stream
came from an alternative source. Alternatively, two channels could be configured for the
same host computer, each with different access rights to suit particular situations.
Groups
In order to accommodate potentially large numbers of users and devices, A.I.M. uses
a system of groups: User Groups, Receiver Groups and Channel Groups. Groups
allow the administrator to apply collective settings to all members and also to take
full advantage of
Inheritance
. Inheritance allows members of a group to benefit from
settings and permissions made within other groups to which their group is linked. This
saves administration time because members do not need to be individually altered. For
instance, if Sam is in User Group 1, all Channels accessible to User Group 1 will be
available to Sam.
User types
This guide refers to the two main categories of users involved with the A.I.M. system:
• An
Admin (administrator) user
accesses the A.I.M. system via a network-linked
computer running an Internet browser. Once the necessary username and password
have been entered, Admin users can make changes to the operation of the A.I.M.
system.
• A
Regular user
has a keyboard, video monitor and mouse (plus speakers where
appropriate) attached to an AdderLink Infinity receiver unit and can access one or
more computers that are linked to AdderLink Infinity transmitters. The AdderLink
Infinity receiver provides an
On-Screen Display
(
OSD) that lists all accessible
computers and allows easy access to them.
security
Security considerations form a major part of A.I.M. operation, ensuring that users have
rapid access only to the systems for which they have permission. At its core, A.I.M.
manages an important three-way relationship between the users, the AdderLink Infinity
receiver(s) and the channels from the host computers.
The diagram shows a representation of the three-way
relationship which exists between
users, receivers and channels.
To successfully gain access to a channel:
•
The user requires permission to use the receiver,
•
The receiver requires permission to connect with the channel,
AND
•
The user must have permission to access the channel.
In most cases, the need for three access permissions per connection is unnecessary and
raises administration overheads. Hence, by default, A.I.M. grants open access for the user
to the receiver and the receiver to the channel while restricting the final, most crucial
piece of the puzzle. For those who require it, the lock upon the user to receiver stage
can be applied individually or globally.
