Smart TV Develop Application Basics Web Applications Guides Smart Hub Preview Smart Hub Preview This topic describes how you can use Smart Hub Preview to show deep links to application content in the Smart Hub launcher. The Smart Hub Preview feature allows you to show content when the user hovers over your application icon in the launcher. The user can click the preview tile to open the content directly within the application. You can use the preview to promote new or personalized content to the user. All Samsung TVs from 2016 through 2021 support Smart Hub Preview. It is also supported on the TV emulator since Tizen TV Extension 2.3.1. Figure 1. Preview panel There are 2 kinds of previews. You can select 1 of them for your application: Public preview shows the same preview content to all users. The preview content is defined by a remotely-hosted JSON file. You can configure the JSON file to expire and refresh at a specific time. Personal preview shows preview content personalized for the user. The preview content is defined by a JSON file managed by a background service application running on the TV. You can implement the preview to suit the content of the application. For example: A video application can have sections for "Popular videos", "Resume playing", and "My playlists". A sports application can have sections for "Top games this week" and "My team". A news application can have sections for "Today's headlines" and "Local weather". A games application can have sections for "Top games now" and "Recently played games". The following figure illustrates the parts of the preview feature. Figure 2. Preview parts The launcher contains icons for quick access to common functions and applications. When the user hovers over the application icon in the launcher, the preview panel is shown. The preview panel can have multiple sections. Each section can have multiple tiles. Each tile deep-links directly to content within an application. When the user clicks a tile, the application opens to the deep-linked content.
