3G / HD / SD Up / Down / Cross Converter with Audio Embedder and De-Embedder

SAMIM UDC-3455 module is a broadcast quality modular Up / Down / Cross converter that can convert audio/video formats among 3G, HD, and SD standards with multiple frame rates. This module embeds each pair of processed audios into the output video and extracts audio from SDI video input.


SAMIM UDC-3455 is a broadcast quality modular up  down  cross converter that can convert video formats among 3G, HD, and SD standards. Frame synchronization (with video timing adjustments), color correction, image enhancement, and aspect ratio conversion (with AFD support) are supported by the module.
It includes an audio crosspoint giving the user great flexibility in selecting the source of embedded audio pairs and audio outputs. Advanced audio processing, including delays, gains, and L/R swap, can be applied to the audio sources from de-embedded audio, external AES, and analog inputs. Video pattern and audio tone generation can help users test the chain without input sources. The module can also compensate for an input loss with black, freeze, or pattern on the output.
Moreover, support for common ancillary standards and an option to use fiber I/O via an SFP module, make UDC-3455 an excellent option for most signal chains in professional broadcast centers. Control and monitoring can be done using a friendly web-based user interface, frame front panel, and SNMP protocol.
