Section 1 — Channel Branding Overview
Content Gateway
Content Gateway describes the hardware and software used to interface a
Maestro system to an external network production environment. The
Content Gateway protects the Maestro system from unauthorized external
LAN users, and provides the methods by which branding elements are
transferred to the Channel Branding.
The Content Gateway must be configured to support permission based
external user access allowing NFS transfer of branding element data files to
defined folders that are supervised by the Content Gateway. External users
also have the ability to transfer branding elements from the defined folders.
Branding elements stored in the defined folders are the element files pre-
served in the original production data formats.
The Content Gateway may be installed on the Maestro Deployment PC
Computer. If the Content Gateway is implemented on the Deployment PC,
the Content Gateway branding element transfer folders must also be
located on the Deployment PC.
Note Installation of the Content Gateway requires hardware not provided by Grass
Valley. See
Content Gateway and LAN Architecture fro more information.
Ingest of Branding Elements
Ingest describes the Maestro system activities associated with acceptance of
externally generated branding elements, element format conversion and
loading of elements to the associated Channel Branding storage media.
Transfer of externally generated elements is implemented as a simple
Network File System (NFS) placement of the branding element in Maestro
system defined folders managed by the Content Gateway. Once the
element is placed in the defined folders, Ingest converts the element to the
internal Channel Branding data format for the type of branding element in
preparation for transfer to the associated Channel Branding’s storage. The
transfer of the converted element to the Channel Branding storage is com-
pleted automatically without operator intervention or the need to deploy a
new configuration. If configured as “automatic”. There is a manual deploy-
ment mode that can also be configured via the Content Definition table.
The Content Creation environment is responsible to ensure that branding
element filenames are correctly defined to properly link element configura-
tions with associated configuration slots and content.
In the special case of Text Crawls and CGText, the Ingest processes the
command file created using the Channel Branding Visual tool, prepares the
file to be used by the Channel Branding and posts the processed data to the
Channel Branding storage.
