EEG Alta-2110 Caption Encoder

About

The EEG Alta-2110 connector allows for the comprehensive monitoring and management of the EEG Alta-2110 captioning system. This solution is specifically designed to integrate with the SMPTE 2110 suite of standards, bridging the gap between cloud-based captioning services and local IP-based video production environments. By interfacing with the iCap Alta software via HTTP, this connector provides a centralized window into virtualized captioning workflows.

Key Features

  • Virtualized SMPTE 2110 integration: Seamlessly monitor software-defined captioning tailored for 2110-30 (audio) and 2110-40 (ancillary) media streams.

  • Automated NMOS support: Full visibility and control over NMOS IS-04 and IS-05 protocols for automatic registration and connection management of media streams.

  • Dynamic instance management: Easily create, edit, and track multiple encoder instances, each with unique stream, iCap, and Telnet settings.

  • Flexible output formatting: Switch between SMPTE 334 CEA-708 VANC and OP 47 EBU Teletext packets to meet diverse regional broadcasting requirements.

  • Comprehensive health monitoring: Track real-time iCap connection status, PTP grandmaster synchronization, and detailed logging for every encoder instance.

Use Cases

IP-Based Closed Captioning Workflow

Challenge: Transitioning from traditional SDI hardware to an IP-centric SMPTE 2110 environment while maintaining reliable closed captioning.

Solution: The EEG Alta-2110 connector integrates the virtualized encoder into the management platform, allowing operators to route 2110-40 ancillary data and manage cloud-based captioning through a single interface.

Benefit: Reduces the physical hardware footprint and simplifies the transition to ST 2110 infrastructure.

Multi-Language International Broadcasting

Challenge: Managing different captioning standards (CEA-708 vs. OP 47) and multiple languages across various global regions.

Solution: Use the connector to configure DVB Text settings and toggle output formats per instance, supporting up to 6 language services and specific Teletext magazine/page numbers.

Benefit: Streamlines global content distribution by allowing rapid reconfiguration of output standards via software.

Legacy Bridge Integration

Challenge: Synchronizing modern IP-based captioning data with legacy SDI encoders or older downstream devices.

Solution: Leverage the Telnet Settings management to clone "CTRL+A" style caption data from an iCap IP connection and route it to legacy hardware.

Benefit: Protects existing investments in SDI hardware while modernizing the core captioning workflow.

Technical Reference

Prerequisites

  • iCap Alta Virtual Machine must be deployed on a supported host (VirtualBox, Cisco, or Microsoft Hyper-V).
  • Network connectivity is required between the system and the Alta VM via HTTP (default port 80).
  • iCap account credentials (Company, Username, Password) are required for cloud-based captioning functionality.
  • SMPTE 2059 PTP Grandmaster is recommended for accurate video frame rate interpretation and VITC timecode generation.
