Local Storage

All digital signage systems, regardless of size, utilise the local storage of media players to store content and playlists ready for playback.

Local storage common features and considerations:

  • Used to store and playback the current playlists for the day, week, or month of digital signage content (dependent on new content update frequency)
  • May be used to store upcoming playlists and content (ie Monday morning messages)
  • May be used to store incidental playlists and content (ie fire alarm evacuation messages)
  • Size requirements varies depending on the following criteria:
    • Content types and file sizes (plain text, pictures, videos, et al)
    • Disk space used for current playlists and schedules
  • Local storage media types:
    • Onboard hard drive
    • SD card
    • Connected USB storage media

Remote Network Storage

Remote network storage common features and considerations:

  • Large-scale digital signage systems commonly require a centralised repository to digitally store all content assets
  • Content assets include playlists, content (images, videos, text, et al), schedules, and templates for a digital signage system
  • A Content Management System (CMS) is used to manage assets stored on the remote network storage
  • Common remote network storage methods:
    • On-premises Network Attached Storage (NAS, shared drive)
    • Cloud-based storage (ie Amazon Web Service)
    • Wide Area Network (WAN) storage, Storage Area Network (SAN)
  • Size requirements varies depending on the following criteria:
    • Content types and file sizes (plain text, pictures, videos, et al)
    • Total disk space used by all unique content and digital signage assets
  • Large-scale digital signage systems can impact network traffic and bandwidth. Any content updates to digital signage endpoints should be scheduled to occur during off-peak network activity periods

Note: Never use CD, Tape, or DVD as a content storage media unless for archiving purposes

Note: Planning and deployment of digital signage remote network storage must be factored in to ICT architecture design

Content Management System

A digital signage Content Management System (CMS) facilitates the administration and management of digital signage assets as it relates to content creation, signage display management, scheduling, and publishing.

CMS common features and considerations:

  • Small-scale: Media player with onboard CMS:
    • Suited for deployments of 20 or fewer digital signage endpoints
    • Limited network integration
    • Limited remote management functions
    • Content updates usually cannot be done remotely (especially for USB storage media)
  • Large-scale: On-premises server solution:
    • Central CMS server solution managing many network-connected digital signage endpoints
    • Suited for deployments of 20 or more digital signage endpoints
    • Full integration with local network services
    • May adopt ICT security policies regarding administrator access
    • May adopt ICT governance policies regarding software and content updates
    • Must be factored in to ICT architecture design
  • Large-scale: Cloud based CMS:
    • Similar to on-premises server solution (see above)
    • May use Amazon Web Service, Microsoft Azure, or digital signage manufacturer solution
    • ICT hardware cost savings
    • Must be factored in to ICT architecture design
