Novastar TB20 Plus New Generation Multimedia Player Box Support Sync & Async Modes For Indoor Outdoor LED Display
Introduction
The TB20 Plus is a new generation of multimedia player designed for full-color LED displays. This multimedia player integrates playback and sending capabilities, allowing users to publish content and control LED displays with a computer, mobile phone, or tablet. Working with the superior cloud-based publishing and monitoring platforms, the TB20 Plus enables users to manage LED displays from an Internet-connected device anywhere, anytime.
The TB20 Plus supports synchronous and asynchronous modes and can play content from a USB drive, satisfying various playback demands. Multiple protection measures such as terminal authentication and player verification are taken to keep the playback secure.
Thanks to its reliability, ease of use, and intelligent control, the TB20 Plus becomes a winning choice for commercial LED displays and smart city applications such as fixed displays, lamp-post displays, chain store displays, advertisement players, retail store displays, door head displays, shelf displays, and much more.

HDMI IN | 1x HDMI 1.3 input connector
. Maximum input resolution: The pixel clock cannot exceed 164 MHz. . Maximum input: 2048×1024@60Hz . HDCP 1.4 compliant, backwards compatible with HDCP 1.3 . No support for interlaced signal input . Support for custom resolutions: - Custom width range: 64~2048 pixels (64×64@60Hz~2048×1024@60Hz) - Custom height range: 64~2048 pixels (64×64@60Hz~1024×2048@60Hz) Note: The resolution of HDMI IN can be customized by changing the preset EDID, so the external source must support custom resolutions. . In synchronous mode, HDMI is used as the video source and users can enable full-screen scaling to make the image fit the screen automatically. Requirements for full-screen scaling in synchronous mode: - 64 pixels ≤ video source width ≤ 2048 pixels - 64 pixels ≤ video source height ≤ 2048 pixels - Maximum resolution: 2048 ×1024@60Hz - Images can only be scaled down and cannot be scaled up. Note: The pixel width and height of the video source must be greater than or equal to the pixel width and height of the screen, respectively. |
