USB Slideshow & Signage is a software application designed to run on Android TV and Amazon Fire TV devices. Its primary function is to convert a standard television into a dedicated signage or slideshow display for photos and videos stored on a USB drive. The application automatically detects and plays media from the connected USB storage, eliminating the need for manual file selection. Users can also transfer media files to the device wirelessly via FTP upload. Key features of the application include customizable playback options. Users can choose to have media displayed in a specific order or in a randomized shuffle sequence. Background music can be added from personal audio files. Additional settings allow adjustment of slide duration and music overlay behavior. Navigation between slides is handled using the standard TV remote control. Typical use cases include retail displays for shop owners, product demonstrations for business owners, customer photo showcases in hospitality venues, and personal photo slideshows in home or family settings. The workflow involves installing the software on an Android TV or Fire TV device, placing media files on a USB drive, connecting the drive to the TV, and then letting the software automatically begin the slideshow. The application is available under four subscription tiers, each offering different levels of access or features as listed on the official site.
