TB50 Playback for Retail and Commercial LED Signs
The NovaStar TB50 is a Taurus-series multimedia player with two Gigabit Ethernet LED outputs and a maximum load of 1.3 million pixels. For a shop display or advertising screen, it can play stored programs asynchronously or show an HDMI source synchronously. Content publishing and screen control are available from a computer, mobile phone or tablet.
The player includes 16 GB of internal storage and can play one 4K video or two 1080p videos. Its media-decoding capability is separate from the screen loading capacity. Connected installations can use cloud-based publishing and monitoring.

Configuration Before Installation
For HDMI synchronous playback, the documented full-screen scaling function accepts a source width of 64–2048 pixels and scales images down only. It cannot upscale in that mode. The two LED outputs can be used as primary ports, or one can serve as a backup for the other.
Network priority is wired Ethernet, then Wi-Fi, then 4G. A 4G module is not supplied as standard. GPS time synchronization requires the specified 4G module, while NTP synchronization is another option for multi-screen playback.


Frequently Asked Questions
What is the difference between TB50 and TB60?
The linked specifications give TB50 two LED Ethernet outputs and a 1.3 million pixel load. TB60 has four LED outputs and a 2.3 million pixel load. Both documents list 1 GB RAM and 16 GB storage.
Can TB50 use one Ethernet port as a backup?
Yes. Both ports are primary by default, but the device can be configured with one primary and one backup port. Account for the chosen arrangement when planning the screen connections.
Does TB50 upscale an HDMI input?
The synchronous full-screen scaling function in V1.0.0 supports downscaling only, with a video source width from 64 to 2048 pixels. It does not upscale the source.
Can I use 4G and GPS synchronization without extra hardware?
No. The TB50 ships without a 4G module. A compatible module is purchased separately, and GPS time synchronization requires the specified 4G module.
Can TB50 play from an exFAT USB drive?
The linked specification supports Ext4 and FAT32 and excludes exFAT and FAT16. The USB 3.0 Type-A port is used for imported media playback and firmware upgrades.
For a larger loading requirement, review the NovaStar TB60 specifications.
