About Link Electronics CBE-493

Make your video content universally accessible with the sophisticated CBE-493 3GB/HD/SD-SDI Captioning Bridge & Encoder, a state-of-the-art solution from the trusted brand Link Electronics. This advanced encoder is designed to seamlessly integrate into your professional video production workflow, offering unparalleled versatility and reliability.

The CBE-493 is capable of handling three gigabits level B, high-definition, or standard-definition serial digital interface (3GB/HD/SD-SDI) transport streams. It provides three closed caption encoded outputs that maintain the same format as the input, with the added flexibility of one output being optionally decoded. The SDI outputs are expertly re-clocked, enhancing the SDI output eye pattern to a quality that surpasses the original input, outperforming many re-clocking Distribution Amplifiers (DAs) in the market.

This innovative unit preserves all ancillary (ANC) data, including audio, ensuring a seamless transition to the output without any loss of information. The CBE-493 is adept at bridging captions between streams, reading caption data from the bridge input video and inserting it into the encoder input video. It transcends traditional captioning by transcoding CEA-608 captions to CEA-708 captions, then encapsulating both within a Caption Data Packet (CDP) for embedding into the encoder output.

With three selectable bridge modes, the CBE-493 can encode captions from a captioner or teleprompter and revert to the chosen bridge mode post-disconnection. It features a GPI remote, referred to as a "Legalizer," which allows broadcasters to comply with FCC mandates by adjusting caption positioning, ensuring that captions do not obstruct critical on-screen information.

Embracing the future of live captioning, the CBE-493 is IP captioning ready, offering a more reliable and readily available alternative to traditional telephone lines for live captioning via existing internet connections.

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 allows for dual IP caption connections at a single address. This connectivity ensures that up to four captioners can interface with the unit, enabling smooth transitions during extended live captioning sessions.

Backed by Link Electronics' standard 10-year warranty and 24/7 customer support, the CBE-493, affectionately known as "The Bridge," meets and exceeds the high-performance, flexibility, and reliability standards expected from Link Electronics products. Whether you're a broadcaster, content creator, or live event producer, the CBE-493 is the ultimate tool for ensuring your content is inclusive and compliant with accessibility standards.
