It opens in the original editor and can’t be converted. | | #### **Collection** | A container that holds one or more layout entries with play rules and scheduling capabilities. | | #### **Collection Entry** | An individual layout within a collection. Each entry can have its own layout configuration, content, lead zone, and play rules. | | #### **Content Warning** | A layout that span several connected displays as a video wall. | | #### **Layout** | The visual arrangement of content zones (single pane, two pane, etc.) within a collection entry. | | #### **Lead Zone** | The designated zone within a layout entry that controls when the collection advances to the next entry. Only one zone per entry can be the lead zone. | | #### **Play Rules** | Filters that determine when content is eligible to display based on date, time, recurrence patterns, or display labels. | | #### **Program** | A legacy multi-segment layout container. Supported in single-zone entries. For new content, we recommend playlists. | | #### **RRules (Recurrence Rules)** | Advanced scheduling patterns that allow for complex, repeating schedules (e.g., "every first Monday" or "weekdays only"). | | #### **Single-Zone/Multi-zone entry** | An entry with one zone, or with two or more. This determines whether programs can play. | | #### **Unified View (E500)** | A layout that spans several connected displays as a video wall. | | #### **Zone** | An individual content area within a layout where you place content items, playlists, or programs. | ## Related - [How to Set Up Collections & Layouts (New Edition)](/how-to-set-up-collections-layouts.md) - [Common Setup Scenarios](/common-setup-scenarios.md) - [Tips for Success](/tips-for-success.md)
