The NAMC-ODSP-M is a DSP-based media processing Advanced Mezzanine card (AMC) for use in MicroTCA® (μTCA, MTCA) and AdvancedTCA® (ATCA®) systems. It provides high density voice and video transcoding capabilities, with a broad range of audio and video codecs and algorithms, including G.711, G.729, Opus, AMR-WB, EVS and H.264, in a compact AMC module. An on-board FPGA simplifies management while enabling the customization of the module to suit specific application needs.
