PURE3
— PURE3
®
is specifically designed for network transmission of real time media
(such as video or graphics, audio, data, and whiteboard elements). It features both spatial
and temporal image compression, which allows for efficient bandwidth usage and eliminates
the need for forward error correction.
•
PURE3 streams always contain video or graphic elements.
•
PURE3 streams may contain audio, data, and whiteboard elements that are associated
with the video and graphic elements.
Streaming media (stream)
— Multimedia that is constantly received by (and normally
presented to) an end-user while being delivered by a streaming provider. Internet television
is a commonly streamed medium. Streaming media (stream) in this guide refers to a PURE3
media stream that is produced by a VN-Matrix encoding device.
Element
— This term refers to the video/graphics, audio, (user) data, and whiteboard
(annotation data) content that is contained within a stream.
Device license
— This term refers to the number of licensed features that are available
on a device within a VN-Matrix system. All devices contain a default license that offers a
default level of functionality. See
on page 60 for information about device
licenses.
Controller license
— This term refers to the license that is applied to the VNM EC 200.
Controller Firmware and License Updates
on page 182 for information about
controller licenses.
(User) Data
—
This term refers to the transfer of user data between an encoder and a
decoder. User data is created at the encoder, placed into the PURE3 stream, and sent to
the decoder. The data is received in the same form that it was transmitted. This method of
data transfer is unidirectional and can only be sent from an encoder to a decoder.
Whiteboard (wb) data
—
Also known as annotation data, whiteboard data outputs text
and/or simple pointer annotation onto local displays that are connected to VN-Matrix
encoders or decoders. This type of data is bidirectional, which allows a decoder to send
whiteboard data to an encoder.
Cluster
— This refers to VNM EC 200s that are paired in a redundant configuration. A
cluster IP address is used to access both VNM EC 200s at the same time.
Cluster IP address
— This refers to a single IP address that is used to access paired
VNM EC 200s. A unique IP address on the same subnet as assigned to the
eth0 port of the primary and secondary VNM EC 200s is used as the cluster
IP address.
NOTE:
When configuring the controller IP address of VN-Matrix devices, use the
VNM EC 200 cluster IP address.
Features
•
Monitor, configure, and manage all VN-Matrix units as a system.
•
Supplies the network heartbeat for encoder and decoder synchronization and
communication.
•
High-level interface provides single point of control for external control systems.
•
Manage multiple VN-Matrix systems in combined or independent domains.
•
Provides redundant control in mission-critical applications.
