Multiple Display Synchronization Guide

Sync Multiple Bharat Signage Devices to Play in Perfect Harmony​

📌 Overview​

This guide walks you through setting up multiple Bharat Signage Android devices to play synchronized content—starting at the same timestamp, frame-perfect, with optional smooth playback. This is ideal for installations like video walls, digital menu boards, or synchronized ads across screens.

🔗 Required:
Visit the Bharat Signage CMS offline USB setup page:
https://cms.bharatsignage.com/offline-usb/ Use version 4.9.16 or 4.10 for synchronization features.

🛠️ Step-by-Step Instructions​

🧩 Step 1: Configuration Settings​

In the Configuration tab of the CMS page:

  1. Go to Advanced Settings
    • ✅ Click Generate Communication Code

      This enables inter-device communication.

    • ✅ Enable Communication Tracker

      This ensures timing consistency across displays.

    • ✅ (Optional) Enable Smooth Playback

      Improves playback sync and reduces visual jitter.

🧭 Step 2: Zone Sync Setup​

Switch to the Zone Setup tab:

  1. Enter a Sync Code

    You can use any simple identifier (e.g., hello, sync123, or zone1).
    All devices using the same code will play in sync.

  2. Zone-Specific Playback

    • To sync only one zone, use zone1 as your sync code.
    • You can also sync other layouts like zone2 or zone3 for split screen scenarios.

💾 Step 3: Download Required Files​

  • Download both the:
    • ✅ Template file
    • ✅ Setup file

These files contain your configuration and sync logic.

📁 Step 4: Prepare USB Pen Drive​

  1. Create a folder on your USB named:
    bharatsignage

  2. Place the following files into this folder:

    • ✅ Bharat Signage APK file
    • ✅ configuration file
    • ✅ setup file
    • ✅ template file

🗂️ Step 5: Folder Structure​

Your pen drive should look like this:

bharatsignage/
├── configuration.xml
├── setup.csv
├── zone1/
│ ├── video1.mp4
│ └── video2.mp4
├── zone2/
│ └── ...
├── zone3/
│ └── ...
  • zone1/ – Full-screen sync content
  • zone2/ – Split-screen (2-part) content
  • zone3/ – Split-screen (3-part) content
  • configuration – Contains settings
  • setup – Auto-connects Wi-Fi or other startup preferences

🔌 Step 6: Deploy to Android Devices​

  1. Plug the USB pen drive into your Android TV or media player.
  2. Use the remote control to open the File Browser.
  3. Install the APK first.

    ⚠️ The APK must be installed before inserting the sync files to allow system-level modifications.

  4. The app will automatically read configuration and enable synchronization.

🔌 Step 7: Reboot Device (Optional)​

  • After installation, you can reboot the device to ensure all settings are applied correctly.
  • The app will automatically start syncing content based on the sync code provided.

🎯 Final Notes​

  • All devices must use the same sync code to stay in perfect sync.
  • Ensure date/time settings are consistent across devices.
  • If one display lags, it will automatically catch up during the next sync cycle.
  • For smoothest results, keep video files identical in format, bitrate, and resolution.
