Embodiment 1
[0038] This disclosure provides an audio stream metadata in a 3D audio model and describes it in detail.
[0039] Streams, which are combinations of audio tracks required to render passes, objects, higher-order ambience components, or packages. The relationship between the audio track format set and the audio channel format set, or the relationship between the audio track format set and the audio package format can be established through the audio stream format element.
[0040] The audio stream metadata includes an attribute area and a sub-element area.
[0041] Attribute area, including audio stream name, audio stream identifier and audio stream format description information;
[0042] The sub-element area includes one of audio channel format reference information and audio package format reference information, and also includes audio track format reference information.
[0043] Among them, the attribute area includes the general definition of audio stream metadata. The a...
Embodiment 2
[0061] The present disclosure also provides a method embodiment inherited from the above embodiment, which is used to generate audio stream metadata. The explanation based on the same name meaning is the same as the above embodiment, and has the same technical effect as the above embodiment. Here No longer.
[0062] A method for generating audio stream metadata, such as figure 2 shown, including the following steps:
[0063] Step S110, generating audio stream metadata in response to the user's setting operation on the audio stream metadata, the audio stream metadata including:
[0064] Attribute area, including audio stream name, audio stream identifier and audio stream format description information;
[0065] The sub-element area includes one of audio channel format reference information and audio package format reference information, and also includes audio track format reference information.
[0066] The user's setting operation for the audio stream metadata may be an o...
Embodiment 3
[0078] image 3 A schematic structural diagram of an electronic device provided by Embodiment 3 of the present disclosure. Such as image 3 As shown, the electronic device includes: a processor 30 , a memory 31 , an input device 32 and an output device 33 . The number of processors 30 in the electronic device can be one or more, image 3 A processor 30 is taken as an example. The number of memory 31 in the electronic device can be one or more, image 3 Take a memory 31 as an example. The processor 30, the memory 31, the input device 32 and the output device 33 of the electronic device can be connected by bus or other methods, image 3 Take connection via bus as an example. The electronic device may be a computer, a server, and the like. Embodiments of the present disclosure are described in detail by using an electronic device as a server, and the server may be an independent server or a cluster server.
[0079] As a computer-readable storage medium, the memory 31 can ...
