The 7837CDM line of composite analog to serial digital converters are broadcast quality decoders with an extensive list of features. High quality analog audio A/D converters can be packaged with the decoder to create a video/audio frame synchronizer with audio embedding. Within the 7837CDM series, adaptive 3D comb filtering technology is utilized to eliminate moving artifacts typically introduced during the decoding process. This makes the 7837CDM series ideal for use in applications where the signal is destined to enter compression systems. The 7837CDM series utilizes 12 bit video ADCs for superior precision and image quality. The 7837CDM series is fully SNMP enabled when used in conjunction with a 7700FC frame controller card. With full SNMP capabilities, the 7837CDM series can also be controlled by any SNMP enabled Evertz control panel like the CP-2232E, amongst others. In addition to SNMP control, the 7837CDM series can be controlled locally used its internal On-Screen-Display capabilities.
