Requirements and recommendations A product that supports playback of Dolby Digital Plus bitstreams contained in an online delivery format must meet all defined requirements. The recommendations assist you to build a high-quality product.
Dolby Digital Plus streams in online delivery formatThe Dolby Digital Plus format provides a high level of flexibility and can support complex bitstream configurations. To minimize impact on decoding devices while ensuring that a wide range of applications can be supported, some constraints are applied to the permitted bitstream structure and to bitstream parameter settings.
Dolby Digital Plus and MPEG-DASHThese topics provide guidance to assist you in meeting the requirements for playing back Dolby Digital Plus streams using the MPEG-DASH standard in conjunction with the ISO base media file format.
Dolby Digital Plus and HTTP Live StreamingThis section specifies the required data formatting and signaling between the server (sender) and the clients (receivers) to use Dolby Digital Plus audio bitstreams in Apple HTTP Live Streaming audio/video (A/V) delivery applications.

HTTP Live Streaming

HTTP Live Streaming is a protocol developed by Apple for transferring streams of media data. HTTP Live Streaming supports both live broadcasts and prerecorded content (video on demand).

HTTP Live Streaming uses segmented MPEG-2 transport streams or fragmented MP4 files for streaming a multimedia presentation that contains both audio and video content, and uses segmented packed audio or fragmented MP4 files for streaming audio-only content. These segmented streams are created from unbounded MPEG-2 transport streams, packed audio, or fragmented MP4 files by using a segmentation tool. This diagram shows the content preparation process for HTTP Live Streaming.
