SMPTE ST 2110/4K/3G/HD/SD Closed Caption Encoder with Media-to-IP Streaming

Interact with this product in a Layout Tool:

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 SCORPION 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 VistaLINK® PRO-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' VistaLINK® PRO locally or remotely.

Features & Benefits

  • Simultaneously encodes new CEA-608 and CEA-708 captions onto 4K/3G/HD/SD-SDI video
  • Supports caption encoding on dual video paths to simultaneously apply the same captions to two video sources (e.g. to both SD and HD signals)
  • Built-in CEA-608 and CEA-708 closed caption decoders
  • Closed caption shifting to avoid overwriting emergency alert messages
  • Support for SMPTE ST 334M/CEA-708 and CEA-608 captions onto 4K/3G/HD/SD-SDI video
  • Supports control and insertion of captions over Ethernet TCP/IP, RS-232/RS-422 serial and telephone modem
  • Save or insert captions directly to or from a file (CEA-608, Procap, SCC, CDP) on a local storage and are accessible via FTP
Sample Application: Captioning and Streaming Media Over IP
