The Evertz 7812XC-AES8-3G+DEE+DAPDD+AC3E is a highly advanced, multi-function modular card designed for the 7800-series frame, serving as a comprehensive signal processing hub for broadcast video and audio. Its core function is as a high-quality cross converter, capable of up, down, and cross-conversion between various SD, HD, and 3G-SDI video standards (e.g., 1080i to 720p, or SD to HD). Beyond this, the extensive suffix denotes a suite of integrated premium options: it includes eight channels of AES digital audio I/O for embedding, de-embedding, and processing; comprehensive Dolby Digital (AC-3) and Dolby-E (DEE) decoding/encoding for surround sound workflows; and advanced audio processing with downmixing and loudness control (DAPDD—Digital Audio Processing & Dolby Digital). This makes the card an all-in-one solution for complex format conversion and audio handling tasks, such as preparing content for international distribution, live broadcast, or archive repurposing.

The card's integrated audio capabilities are particularly robust. It can de-embed audio from an incoming SDI stream, process it (including sample rate conversion, loudness normalization, and channel remapping), and then re-embed it into the newly converted video output. The Dolby options allow for transcoding between multi-channel audio formats and ensuring compliance with broadcast loudness regulations. The inclusion of both coaxial and optical digital audio I/O provides flexible connectivity to external audio routers or processors. All these processes are handled with minimal latency and high fidelity, preserving both video quality and audio integrity throughout the conversion chain.

As part of the modular 7800-series ecosystem, this card is managed and monitored through the frame's centralized control software, allowing for remote configuration, preset recall, and real-time status monitoring of all its complex functions. Its high-density, multi-purpose design consolidates what would traditionally require several separate pieces of equipment into a single card slot, saving rack space, reducing power consumption, and simplifying system design. The Evertz 7812XC-AES8-3G+DEE+DAPDD+AC3E is engineered for the most demanding master control, playout, and production environments, providing a powerful, reliable, and scalable solution for managing the intricate video and audio format requirements of modern broadcasting.
