Method and apparatus for processing secondary media stream embedded in MPEG-H 3D audio stream

The present invention relates to a method and apparatus for processing a secondary media stream embedded in an MPEG-H 3D audio stream. The invention also relates to a method, a device and a system for bypass loading processing of a packed media stream. In an embodiment, the apparatus comprises: a receiver to receive a bitstream; and a splitter for identifying a packet type in the bitstream and splitting into a primary stream and a secondary stream based on the identification of a value of the packet type in the bitstream. 本发明涉及用于处理嵌入在MPEG-H 3D音频流中的辅媒体流的方法及设备。本发明还涉及用于打包媒体流的旁路载荷处理的方法、设备及系统。在实施例中，所述设备包括：接收器，其用于接收位流；及分离器，其用于识别所述位流中的数据包类型且基于所述位流中的所述数据包类型的值的所述识别来分离成主流及辅流。
