The AJA HI5-3G 3G/Dual Link/HD/SD-SDI to HDMI Mini-Converter is a specialized, high-performance device designed for reliable and high-quality conversion from professional SDI video signals to consumer and prosumer HDMI displays. It serves as a critical link in environments where a broadcast or production feed needs to be monitored on modern televisions, projectors, or digital signage displays that lack SDI inputs. The converter accepts a wide range of SDI standards, from legacy standard definition up to 3G-SDI carrying high-frame-rate 1080p HD signals, and transforms them into a pristine HDMI output. This process includes de-embedding the audio from the SDI stream and embedding it into the HDMI output, ensuring both picture and sound are faithfully delivered. A key feature is its support for Dual Link SDI, allowing it to handle high-resolution formats like 2K, which is essential for post-production and cinema workflows.

Built into AJA's renowned rugged, compact metal housing, the HI5-3G is engineered for continuous, reliable operation in demanding settings such as mobile production trucks, broadcast control rooms, and edit suites. It operates as a standalone unit with automatic signal detection and formatting, requiring no user configuration or external software—just power and cables. The inclusion of both an input and output SDI connector allows for a loop-through function, enabling the original SDI signal to continue down the chain to other equipment. By providing a robust, transparent, and format-agile conversion path, the HI5-3G ensures that high-quality professional video can be accurately displayed on virtually any modern screen, making it an essential tool for monitoring, presentation, and distribution tasks.
