[0028] see figure 1 , figure 1 It is a flow chart of the control method of audio data decoding provided by the embodiment of the present invention, such as figure 1 shown, including the following steps:

[0029] Step 101. Encapsulate DSD audio data into audio data packets for audio hardware decoding.

[0030] In this step, the DSD data cannot be directly used for audio hardware decoding. If audio hardware decoding is to be performed, an encapsulation protocol must be used to encapsulate the DSD data to obtain audio data packets. For example, the (DOP, DSD OverPCM) protocol can be used to encapsulate DSD data, and the DSD data encapsulated using the DOP protocol is called DOP data, and the above DOP data can be directly used for audio hardware decoding, that is, transmitted through audio hardware decoding channels DSD data encapsulated using the DOP protocol. It should be noted that DSD data cannot be directly decoded by audio hardware. It is necessary to use the DOP protoc...

Abstract

The invention provides an audio data decoding control method and a mobile terminal. The method comprises steps of encapsulating DSD audio data into a voice data package capable of being decoded by audio hardware, identifying an audio decoding way used by an audio player, decapsulating the audio data package to achieve DSD audio data if the audio decoding way is an audio software decoding way, converting the DSD audio data into PCM audio data, decoding the PCM audio data via the audio software decoding way, and otherwise decoding the audio data via the audio hardware decoding way. When the audio decoding way used by the player changes, re-transmission of the DSD audio data can be unnecessary; the audio data package can be decoded via the current audio decoding way, so DSD audio data can be continuously transmitted during software and hardware decoding switch, and user experience can be improved.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a control method for decoding audio data and a mobile [0002] terminal. Background technique [0003] Direct Stream Digital (DSD, Direct Stream Digital) format music is significantly different from Pulse Code Modulation (PCM, Pulse Code Modulation) format music. PCM is to use a certain sampling rate to sample, quantize and encode the analog signal to generate PCM data that conforms to the PCM interface specification. DSD uses a 1-bit bit stream to sample, and uses a high-sampling method to directly convert the analog music signal into a digital signal in a pulsed manner. DSD data does not conform to the PCM interface specification. If it is to be transmitted, it must follow the PCM interface requirements. Repackage and use the PCM interface for transmission. The advantage of DSD data is that the sound quality is very good. There are two methods of hardware decoding and s...
