Universal Blu-ray remotes typically control a wide range of home‑entertainment gear, including TVs, Blu‑ray/DVD players, streaming boxes/players, soundbars and other audio equipment, set‑top boxes, and game/media players.
They commonly include large built‑in code libraries and preprogrammed codes for popular brands, automatic code‑search and direct code‑entry, IR learning to copy buttons from another remote, and macro programming to combine multiple actions into a single button.
Device counts vary by model, with common options for controlling 3, 4, 5 or 8 devices; listings in this set ranged from 3 up to 8.
Most remotes rely on infrared (IR). Some models also include Bluetooth, and a few mention Bluetooth Low Energy (BLE) for pairing with streaming devices.
Several models support IR learning to copy commands from another remote and offer macro programming so a single button can trigger multiple actions (for example, powering on several components together).
Listings include hospitality features such as screw‑on battery compartments and compatibility with security cables for fixed use; at least one model also notes a silver‑ion antimicrobial surface treatment.
