Advanced LE Audio and Auracast Support

The IDC777 simplifies the deployment of next-generation broadcasting, allowing operators to deliver crystal-clear notifications and entertainment through a single, compact module.

  • Full Auracast BAP Compliance: Supports all Broadcast Audio Profile (BAP) configurations. This allows you to optimize your design for ultra-high reliability or critical low latency depending on the venue
  • Ultra-Low 20ms Latency: Achieves a blazing-fast 20ms latency utilizing advanced Qualcomm gaming codecs. This eliminates visible lip-sync delays for assistive device users.
  • Multi-Language Casting: Transmits up to 4 independent mono streams simultaneously. This enables public venues to broadcast simultaneous multi-language announcements or multi-channel audio from a single module.
  • Flexible Sampling Rates: Operates dynamically across all standard frequencies from 8 kHz to 48 kHz. This ensures crystal-clear speech intelligibility and high-fidelity media paths.
  • Innovative Audio Bridging & Repeating: Accepts standard Bluetooth Classic A2DP audio inputs and transcodes them into an Auracast broadcast. It can also receive an active Auracast stream and instantly re-broadcast (re-Auracast) it. This is a vital asset for scaling coverage across massive public deployments.
  • Standalone Headset Assistant: Integrates on-board intelligence to assist and manage headset connections directly. This allows assistive accessories to function independently without requiring a smartphone hub.

Universal Backward Compatibility

The IDC777 Combines full Bluetooth Classic and LE Audio systems natively. This ensures immediate compatibility with older product specifications. It also supports traditional PIN code pairing methods. This allows older generation devices to securely access cutting-edge public broadcasting networks.

Targeted Deployment Applications

  • Hearing Aid Accessories: Next-generation wireless TV streamers, companion clip-on microphones, and low-power pocket gateways.
  • Public Transit Hubs: Multi-channel, multi-language real-time gate and platform announcements in airports, train stations, and bus terminals.
  • Transit Vehicles: High-reliability on-board audio casting networks integrated across trains, subways, and commercial buses.
  • Educational Institutions: Accessible classrooms, lecture halls, and university theatres streaming direct-to-hearing-aid assistive audio.
  • Public Announcement Systems: Retrofitting existing commercial PA systems to support wireless, long-range Auracast broadcasts.
