The invention provides an audio processing method and device based on a media processing unit, equipment and a medium, and the method comprises the steps: constructing an operator for calculation based on a heterogeneous calculation framework, configuring data processing logic and data flow direction in the operator, obtaining an audio task, disassembling the audio task into audio subtasks which can be executed in parallel, and storing the audio subtasks in the heterogeneous calculation framework; and establishing a mapping relationship between the audio subtasks and operators, allocating computing resources according to a load required during parallel computing of the media processing unit, determining a target computing unit of the operators, calling the target computing unit based on data processing logic and data flow, and executing the corresponding audio subtasks so as to complete processing of the audio tasks. The audio processing method based on the media processing unit is more practical and more efficient.

The invention provides an audio transmission system, electronic equipment and an audio transmission method. In the audio transmission system, a first audio transmission channel is formed between a main control unit and a loudspeaking unit, a second audio transmission channel is formed between a multimedia processing unit and the loudspeaking unit, and the first audio transmission channel is used for receiving an audio signal transmitted by adopting a first audio transmission protocol. The second audio transmission channel is used for receiving an audio signal transmitted by adopting a second audio transmission protocol; the first switch is configured to disconnect the second audio transmission channel when the main control unit obtains an audio signal from the outside through a first audio transmission protocol to enable the audio signal to be transmitted in the first audio transmission channel; and the second switch is configured to disconnect the first audio transmission channel when the multimedia processing unit obtains an audio signal from the outside through a second audio transmission protocol under the control of the main control unit so as to enable the audio signal to be transmitted in the second audio transmission channel.

Moving Picture Experts Group (MPEG) media transport protocol (MMTP) content is received from a source of content such as an ATSC 3.0 source. The MMTP content is used to construct as a Dynamic Adaptive Streaming over Hypertext Transfer Protocol (DASH) files. Constructing the file includes writing media processing units (MPU) header data, fragment header data, and MPU data. Constructing the media files also includes accounting for discarded Fragment Type 3 data in relation to a media data (MDAT) section of the DASH media files. Further, constructing the file includes appending digital rights management (DRM) data to the DASH MPD file. After the file has been constructed, a DASH software media player can play the media content using the file.
