Digital Signage
Digital signage platforms operate under continuous media-playback workloads. Storage selection is therefore determined by sustained read stability, deployed media capacity, player compatibility and content-refresh requirements.
Platform Requirements
Digital signage qualification is primarily determined by sustained playback behaviour, deployed capacity, player compatibility and fleet configuration requirements rather than peak benchmark performance.
Continuous Playback
- Media content may operate in repeated playback cycles with limited idle periods
- Storage access is predominantly sustained and sequential during normal playback
- Playback interruption may be immediately visible at the deployment site
Deployed Capacity
- Storage capacity is determined primarily by the deployed media library
- Content-update frequency may alter storage requirements over the programme lifecycle
- Screen resolution, content format and site-specific media requirements may result in different deployed configurations
Applicable Memory & Storage
Applicable memory and storage forms are selected according to platform configuration and programme requirements. Final configuration is confirmed against the target board layout, interface requirements, operating conditions and programme lifecycle.
Memory
- DDR3 / DDR4 / DDR5 SO-DIMM
- DDR3 / DDR4 / DDR5 U-DIMM
- Qualification is based on the approved operating configuration for the target platform; profile-based operation is evaluated only where explicitly defined within the project configuration
Storage
- 2.5″ SATA III
- M.2 PCIe 3.0
Qualification Process
Qualification scope is defined according to platform configuration, operating conditions and programme requirements. The stages below describe a typical qualification sequence. Scope and sequence may vary according to project requirements.
Requirements Definition
Platform configuration, operating conditions, lifecycle requirements and applicable interfaces are identified.
Configuration Selection
Memory and storage forms are selected against the target board architecture and programme requirements.
Sample Verification
Initial samples are evaluated before configuration approval.
Platform Validation
Compatibility, stability and applicable performance characteristics are verified against the target platform.
Qualification
The applicable configuration is approved according to the defined programme requirements.
Production Control
Production proceeds under established quality-control procedures. Where configuration control is included in the approved programme scope, production follows the defined configuration and change-review requirements.
Post-Deployment Engineering Support
Failure analysis is applied to returned products or reported field issues where root-cause investigation is required. It is not a sequential stage of the qualification process above.
Digital Signage Qualification Priorities
Qualification priorities are defined per programme. On continuously operating signage platforms, the following areas are normally addressed.
Platform Configuration Review
Provide the player specification, storage interface, media-library requirements, content profile, operating conditions and deployment scale. SIMORCHIP engineering will review the applicable memory and storage configuration and define the recommended qualification scope.
