## How to choose
- Is it a full screen with built-in computer? → 8471.41
- Is it just a circuit board without housing? → 8471.50
- Does it rely on LAN for content updates? → 8517.69
- Is video playback its only function? → 8521.90
- Can it be connected directly to a computer? → 8528.52
- Does it work without a computer and is large-scale? → 8528.59
- Is it a box-shaped device connecting to a screen? → 8528.71
## Overlaps & pitfalls
- **Overlaps:** A set-top box (8528.71) may also be LAN-based (8517.69) or self-contained (8528.59).
- **Pitfalls:** "Digital signage player" appears in multiple codes—priority depends on function, not name.
- **No priority rule given**—choose based on the product’s MAIN function: display, playback, network, or form factor
