SyncHear Interactive Sandbox

Test the full synchronization flow in real-time. Change settings in the Venue SaaS Dashboard (Right) to instantly rebrand the PWA (Center) and update the Smart TV (Left).

💡 Real Device Test: Ensure your phone is on the same local network, then scan the TV Simulator's QR code with your phone camera to hear the audio on your personal headphones!

Architecture & Sync Protocols

How SyncHear bridges the legacy gap and scales to native LE Audio Auracast

💻

Option 1: WebRTC Sync

Connected Smart TVs

Software-only, zero-hardware solution for modern venues. TV captures raw audio, streams over WebRTC to cloud/local gateway. Scanning the QR launches PWA which calculates Network Round-Trip Time (RTT) to align audio play rate with TV display clock within 5ms.

  • Zero hardware deployment cost
  • Lightweight PWA (no App Store friction)
  • Dynamic NTP latency alignment
⚡

Option 2: Local Waves

Central Cable & Matrix Feeds

Designed for locked environments (airport lounges, large gym matrix feeds). Connects to analog audio matrix. Emits high-bandwidth micro-Wi-Fi access point (AP). User connects via captive portal, serving synced latency-adjusted audio directly in browser.

  • Supports legacy analog distributions
  • Zero cellular data consumption
  • Serves captive portal web client
🔌

Option 3: Hybrid Dongle

HDMI/USB Plug-and-Play

A scalable legacy bridge targeting individual commercial screens. Dongle captures local TV audio outputs and broadcasts it over local WebRTC Wi-Fi (for legacy headphones via phone) and natively over Bluetooth LE Audio Auracast (direct to earbud pairing).

  • Simultaneous WebRTC + Auracast
  • Future-proof (LE Audio standard)
  • Zero config plug-and-play

Proprietary Intellectual Property & Patent Layers

We are establishing defensive patent positions in three crucial areas to block larger media giants and copycats:

Latency Alignment Protocol Patent filing on NTP-based frame synchronization mechanism matching HTML5 audio playback rates with displays over standard HTTP/WebRTC pathways.
Hybrid Auracast Dongle Hardware utility claims on a device conducting concurrent RF broadcasting of local sound streams over Wi-Fi (WebRTC) and Bluetooth LE (Auracast).
QR-to-Audio Connection Handshake System architecture describing immediate Web App audio routing via dynamic display-generated QR token handshake without hardware pairings.
