Product Literature



The ATOM Closed Captioning processing unit enable the insertion, extraction and monitoring of closed captioning information within a 3G-SDI, HD-SDI or SD-SDI video signal.
When in insertion mode, textual information is transmitted through the units Ethernet port and is then inserted as closed captioning data within the video signal. When extracting closed captioning information, the data is decoded from the video signal and is then available via the units Ethernet port. In monitoring mode, the closed captioning data is read from the video stream and ‘burnt’ into the video stream on the monitor output so that the captions can be viewed on a monitor. The closed caption data is also stored and each channel can retain up to 48 hours of captions including timestamps.
The closed captioning data is processed according to OP-47 or CEA-708. Other standards are available on request.
The ATOM Closed Captioning Interface comes in a compact 1RU 19″ rack mounted unit, and is fitted with dual redundant power supplies for redundancy.
