Now Available: Closed Caption Encoding To Multiple Live Streams


A company known for file-based media workflow orchestration, media streaming and delivery technologies is using the 2018 NAB Show to debut a “one-box solution” for closed caption encoding to multiple live streams.

“Sophisticated” 608/708 caption insertion capability is part of the latest version of Lightspeed Live Stream, Telestream’s multiscreen live encoding and packaging at scale solution for broadcasters and content aggregators.

As Telestream notes, many IP caption insertion systems in use today are cloud-based, requiring content to be moved first to the cloud, there captioned, then re-encoded and re-streamed for delivery. “This introduces significant opportunity for human and mechanical error, ultimately impacting the quality of the final content,” the company says. “In contrast, Telestream’s live captioning solution with Lightspeed Live Stream eliminates restreaming, instead encoding the live captions within the original stream and ensuring the best possible quality.”

Lightspeed Live Stream uses standard captioning protocols to receive caption data, so existing third-party court reporting software can connect to Lightspeed Live Stream via IP.

Telestream will be at NAB 2018, in booth SL3316
