The Evertz 7812HDC-HD is a high-density, modular backplane assembly designed for use within Evertz's 7800 series frame system. It serves as the central interconnection hub and power distribution board for a rack of Evertz signal processing, conversion, and monitoring cards. The backplane provides the necessary data buses, control pathways, and clean DC power to each card slot, enabling high-speed communication between modules and ensuring the entire frame operates as a cohesive, manageable system. This specific model is configured for HD (High Definition) signal processing applications, supporting the bandwidth and data rates required for professional broadcast and production environments.

Installed in a compatible Evertz frame chassis, the 7812HDC-HD backplane defines the capabilities of the system, including the number of available card slots (typically 12 or 14 slots in a 3RU chassis) and the types of cards it can support. It facilitates features such as centralized control and monitoring via Evertz's VistaLink network management software, redundant power supply connections for high availability, and hot-swappable card functionality for maintenance without system downtime. The robust design ensures signal integrity and reliable operation in 24/7 broadcast facilities.

As a critical but often unseen component, the backplane is the foundation upon which flexible and scalable signal processing systems are built. It allows broadcast engineers to populate the frame with a tailored mix of cards for specific tasks—such as audio embedding/de-embedding, format conversion, signal distribution, or quality monitoring—creating a customized and powerful processing hub within a broadcast plant's infrastructure.
