    Closed Captioning Overview 

    Published on 11-08-2012 12:57 PM     Number of Views: 4081 
    1. Categories:
    2. Live,
    3. Video On Demand,
    4. Closed Captioning

    Wowza Media Server® 3.5.0 and later can ingest caption data from a variety of instream and file-based sources and convert it to the appropriate caption format for video on demand and live streaming using the Apple HTTP Live Streaming (Apple HLS), Adobe HTTP Dynamic Streaming (Adobe HDS), and RTMP protocols. This feature helps U.S. broadcasters to comply with the Twenty-First Century Communications and Video Accessibility Act of 2010 by providing captioning for television programs that are distributed over the Internet.

    Closed captioning for video on demand streams

    Wowza Media Server can extract 3GPP Timed Text caption data from MP4 files or from companion files that use Timed Text Markup Language (TTML), SubRip Text (SRT), Web Video Text Tracks (WebVTT), or Scenarist Closed Caption (SCC) formats to specify caption data. This caption data can be injected into Apple HLS streams as CEA-608 captions or into Adobe HDS and RTMP streams as Action Message Format (AMF) onTextData events. For more information, see the following articles:

    • How to configure closed captioning for video on demand streaming
    • How to configure closed captioning language selection for video on demand streaming
    • How to serve sidecar caption files for video on demand streaming
    • Closed captioning configuration reference for video on demand streaming

    Note: Support for Web Video Text Tracks (WebVTT) and Scenarist Closed Caption (SCC) files was added to Wowza Media Server 3.6.

    Closed captioning for live streams

    Wowza Media Server can ingest instream closed caption information from Action Message Format (AMF) onTextData events or CEA-608 data. An Application Programming Interface (API) in Wowza Media Server enables AMF onTextData events to be injected into Adobe HDS and RTMP streams. The ingested caption data can also be delivered in in Apple HLS steams as CEA-608 captions. For more information, see the following articles:

    • How to configure closed captioning for live streaming


    Closed captioning for Apple iOS 6 devices

    The Apple iOS 6 subtitling system uses Web Video Text Tracks (WebVTT), which provides more flexibility in rendering multiple languages and languages that aren't supported in iOS CEA-608 closed captioning. Wowza Media Server 3.6 can convert closed caption data in video on demand (VOD) and live streams to WebVTT subtitles for playback on Apple iOS 6 devices. For more information, see the following article:

    Some video encoders do not include frame rate information in stream metadata (SPS NAL unit VUI data and SDP data). Wowza Transcoder needs proper frame rate information to configure the encoding sessions. When frame rate information is not available, Wowza Transcoder will assume a frame rate of 29.97 frames-per-second. When this happens you will see the following log statement: ...
