IQOYA *CALL for IP audio remote broadcasting

Key Workflow: Build reliable audio contribution links from remote talent to studio with uncompromised broadcast quality over unreliable Internet and Mobile networks

IQOYA *CALL builds reliable, ultra-low-latency audio contribution links over unreliable Internet and 3G/4G networks. Specifically designed for non-technical users, it makes IP contribution as simple as placing a call from a smartphone. Its streaming engine FluidDIP enables both interoperability with third party IP codecs and optimized compensation for IP network impairments. Any administrator can configure IQOYA *CALL via the cloud for in-the-field contribution scenarios, freeing remote talent from technical hassles.

At a glance

IQOYA*CALL provides a full-duplex stereo connection between a remote site and a studio

• Ultra-simple to use: click to dial from contact list just like a smartphone. Dialling from the front panel color screen or from the Web page automatically provides an optimized connection without worrying about networks, protocols, or audio technical parameters
• Easy to manage: all setups are enclosed in the Administrator’s web page. Configure locally or via IQOYA*CLOUD app to anticipate in-the-field contribution scenarios
• Smart quality administration: a smart bar graph displays connection quality in real time. Even inexperienced users can check and manage set-ups during actual field situations
