    Audio passthrough

    • AC-3 (Dolby® Digital™ audio technology)
    • E-AC-3 (EC-3, Dolby® Digital Plus™ audio technology)
    • MPEG-H Audio
    • Dolby® Atmos™

    The Web Receiver SDK supports AC-3 passthrough. You can check the codec support prior to loading content using the CastReceiverContext.canDisplayType() method with the corresponding media type string for each codec.

    To determine whether Dolby® Atmos™ is supported on specific hardware, check the cast.framework.system.DeviceCapabilities.IS_DOLBY_ATMOS_SUPPORTED flag.

    Delivery methods and adaptive streaming protocols

    These are available through use of the Web Receiver SDK .

    • MPEG-DASH

      • DRM Support: Widevine (Level 1)

    • SmoothStreaming

    • HTTP Live Streaming (HLS)

      • DRM Support: AES-128, SAMPLE-AES using Widevine (Level 1)

    • Progressive download without adaptive switching

    With adaptive bitrate streaming protocols, you must implement CORS . To implement an encrypted protocol, including DRM, you should develop a Custom Receiver . See DRM support for more information.

    Subtitles and closed captions

    Your subtitle resources must implement CORS .
