The MIO-CCE-4K/3G is a closed caption encoder for SMPTE ST 2110/4K/3G/HD/SD-SDI video signals that can be housed in any  frame. MIO modules provide native support for numerous captioning interfaces, such as captioning over dial-up phone line, captioning over IP and captioning over serial RS-232/RS-422.

MIO-CCE-4K/3G supports many advanced applications such as on-screen display for real-time monitoring of the encoded closed captions. Applications such as "translating" captions from CEA-608 to CEA-708 or "transcoding" CEA-608 between SD line-21 and HD VANC carriage are natively supported.

The onboard storage may be used for both caption file capture and insertion. With the capture function, the unit can record and store captions that are being actively encoded or already present on the incoming video. The stored files may be retrieved from storage and are useful in cases such as editing/correcting captions from existing content, avoiding complete re-authoring, or for verifying compliance. The insertion function allows files in storage to be directly encoded to video, convenient where an external transfer station is not available.

Taking advantage of the availability of IP connectivity, the MIO-CCE-4K/3G is able to generate a low latency, low bandwidth media-over-IP stream from the embedded tracks in the incoming video. This media may be streamed to the remote captioner, facilitating a complete bi-directional link and negating the need for a POTS/dialup connection.

The MIO-CCE-4K/3G is -capable, which allows for control and configuration via Simple Network Management Protocol (SNMP). This offers the flexibility to manage the module status monitoring and configuration from SNMP enabled control systems such as Evertz'  locally or remotely.
