The ENC6801+D encoder is a high-precision, 12-bit digital encoder that supports NTSC, PAL-B and PAL-M standards.

Standard selection is automatic for 525-line NTSC and 625-line PAL standards. The high-quality encoding is ideal for use in the primary broadcast path, as well as for monitoring purposes.

Part of the 6800+™ core processing frame, the ENC6801+D module can be 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 module is Q-SEE™-compliant, allowing for direct thumbnail monitoring when installed in an Ethernet-equipped 6800+ frame.
