Definitions
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) — This term refers to multimedia that is constantly received by (and normally presented to) an
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
Controller license — This term refers to the license that is supplied to the VNM Enterprise Controller. See the VNM Enterprise Controller User Guide for information about device licenses.
(User) Data — This 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 simple pointer annotation onto local displays that are connected to
