The UDP-203 is able to play all standard optical disc formats, such as 4K UHD Blu-ray, Blu-ray, Blu-ray 3D, DVD, DVD-Audio, SACD, and CD. It also supports connected USB hard drives and thumb drives up to 16TB in capacity, and it has the ability to access content from DLNA servers and SMB shares over the local network.

The newly updated, high-resolution user interface has been designed to be incredibly convenient to navigate, and provides an easy way to manage and access media files from both local and network storage.

The UDP-203 is easy to integrate into any system due to its ability to receive standard IR, RS-232, IR IN, third party IP Control system, and HDMI CEC commands. The player also supports Trigger In and Out, so it can automatically turn on and off other devices connected to it for the ultimate convenience.
