The TS-251+ delivers superior real-time video transcoding (up to 4K H.264) to convert your videos to formats that can be smoothly played on PCs, mobile devices and Smart TVs. It allows for multiple devices to simultaneously view different videos stored on the TS-251+ with on-the-fly hardware accelerated transcoding, saving your time in converting videos to different formats for different devices.
With the benefits of offline transcoding, if you can only connect to an Internet connection with limited/restricted bandwidth, you can still enjoy smooth videos via File Station, Video Station, or the Qfile app by selecting a pre-rendered lower-resolution video, saving system resources of the TS-251+ for other applications. The TS-251+ also allows you to set a dedicated folder for automatic video transcoding.
Use your TS-251+ as a multi-zone multimedia system to fill every corner of your house with your choice of media. You can centrally manage and stream photos, music and videos from the TS-251+ to different rooms from a single device using Bluetooth®& USB devices connected to the TS-251+ (for music streaming only), HDMI, DLNA®, Apple TV® and Chromecast™*. Every room member in different zones can enjoy the convenience and simplicity for media playback and multimedia storage.
Alternatively, to enjoy multimedia yourself, you can choose DLNA-compatible devices, use the Qfile app on an iOS® device to browse videos/photos and play on the TV via Apple TV®, or transform the TS-251+ into a powerful streaming machine with DLNA®, Roku®, Amazon® Fire TV, and Google TV™ support with the support of Plex Media Server.
