About Link Electronics CBE-493

You'll experience advanced technology at its finest with the CBE-493 Captioning Bridge & Encoder, a high-tech device designed to provide superior captioning solutions for your audio and video needs. This state-of-the-art encoder, manufactured by the reputable Link Electronics, is equipped with 3GB/HD/SD-SDI inputs, offering you the flexibility to work with a variety of equipment and formats.

The CBE-493 is a sophisticated 3GB/HD/SD-SDI closed caption encoder that accepts 3GB/HD/SD-SDI transport streams and delivers three closed caption encoded outputs. The SDI outputs are re-clocked, enhancing the SDI output eye pattern and outperforming most re-clocking Distribution Amplifiers (DA). This innovative device ensures the seamless passage of ANC data, including audio, to the output.

This high-tech encoder bridges captions between streams, reading the caption data from the bridge input video and inserting it into the encoder input video. It transcodes CEA-608 captions to CEA-708 captions, wrapping both into a Caption Data Packet (CDP) that is embedded into the encoder output. With three selectable bridge modes, the CBE-493 can encode captions from a captioner or teleprompter and then return to the selected bridge mode once the captioner disconnects.

The CBE-493 also features a GPI remote, referred to as a "Legalizer", that allows you to select the number of lines to be lifted, addressing the FCC mandate that captions should not overlay certain on-screen elements. This encoder is also IP captioning ready, a preferred method for live captioning due to the elimination of less reliable plain old telephone (POTs) lines.

Equipped with four communication ports, including two serial RS-232 ports with adjustable baud rates and two ports tunneled to the Ethernet connector, the CBE-493 offers the ability to connect up to four captioners simultaneously. This feature is particularly useful for live captioning over extended periods.

In summary, the CBE-493 Captioning Bridge & Encoder is an advanced, high-tech solution for your captioning needs, offering innovative features and superior performance that set it apart in the market.
