SUBTITLING

• Does Athensa AirBox supports subtitles? What subtitle formats are supported?

Yes, Athensa AirBox supports subtitles through integrated module called SubtitleBox (license option needed). Supported formats are Subtitle Plus (*.sub), Screen Subtitling/Win2020 (*.pac) and EBU t3264 (*.stl). We do recommend to use Athensa SubtitleBox with Subtitle Plus native format.

• How can I generate DVB subtitles for my channels?

You can use our SubtitlePlus DVB Server which can generate dozens of subtitle streams for single or multiple output channels. The subtitle multiplexing with the video and audio streams can be done by Athensa DVB Muxer or by a third-party multiplexer. SubtitlePlus DVB Server listens to all Athensa AirBox servers and generates the subtitle streams based on the currently running programs and exact timecode. It works completely automatically.

• Do you support CC (closed captioning)?

Closed captioning (CC) is the process of displaying text on a television, video screen or other visual display to provide additional or interpretive information to individuals who wish to access it. Athensa products support CC data for analog TV (EIA-608) with Decklink card and for digital TV (EIA-608 in EIA-708) with Deltacast card. CC data in MPEG2 TS and H.264 TS are supported.
