See how this modular product fits in a frame:
The 7825CCE-AUD-3G is a closed caption encoder for 3G/HD/SD-SDI video signals. This unit has native support for numerous captioning interfaces, such as captioning over dial-up phone line, captioning over IP, captioning over serial RS-232/RS-422 and caption bridging from one input to the other. 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.
Taking advantage of the availability of IP connectivity, the 7825CCE-AUD-3G is able to generate a low latency, low bandwidth audio-over-IP stream from the embedded audio tracks in the incoming video. This audio may be streamed to the remote captioner, facilitating a complete bi-directional link and negating the need for a POTS/dialup connection.
The 7825CCE-AUD-3G supports many advanced applications such as broadcast flag insertion, port echo capability for daisy chaining multiple units together and on-screen display for real time monitoring of the encoded closed captions.

The +CF option adds an on-board compact flash module which 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 the compact flash 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 stored on the compact flash to be directly encoded to video, convenient where an external transfer station is not available.
The 7825CCE-AUD-3G is VistaLINK®-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.
