The XHD6800+AD is a flexible, cost-efficient SD aspect ratio converter for the 6800+™ modular core processing platform. The XHD6800+AGD module adds GPI functionality.
The XHD6800+AD and XHD6800+AGD SD aspect ratio converters offer aspect ratio control of SD input signals with five user presets for aspect ratios. There is a smooth transition when switching between different aspect ratios or when using the GPI control. AFD (active format description) is supported for automated control of aspect ratios.
The XHD6800+AD and XHD6800+AGD controlled manually via card-edge controls, or controlled and monitored via the CCS Navigator™ software application, HTTP web browser, NUCLEUS™ hardware control panels or third-party SNMP-based control applications. The modules are Q-SEE™-compliant, allowing for direct thumbnail monitoring when installed in an Ethernet-equipped 6800+ frame.
