Embodiment 1

[0031] like figure 1 As shown, a flow chart of a method for testing media delay in an Android system provided by an embodiment of the present invention, the method includes:

[0032] S11: Determine the stage to be tested in the media data transmission process;

[0033] S12: Set general input and output ports in the stage to be tested;

[0034] S13: When the media data reaches the stage to be tested, measure the level change time difference of the input and output ports, and the change time difference is recorded as the transmission delay of the media data in the stage to be tested.

[0035] It can be understood that, with the technical solution provided in this embodiment, on an android device, the delay of audio data in the terminal can be tested at a low cost, and only an ordinary oscilloscope can be measured; by obtaining the audio data in the android chain For each node part in the road, specify different GPIO (General-purpose input / output, general-purpose input and outp...

Embodiment 2

[0037] like figure 2 As shown, a flowchart of another method for media delay testing for Android system provided by the disclosed embodiment of the present invention, the method includes:

[0038] S21: Determine one or more stages to be tested in the media data transmission process, and the media data transmission process includes: a media data input stage and a media data output stage;

[0039] S22: Set the general-purpose input and output ports at each stage to be tested by driving;

[0040] S23: When the media data arrives at the stage to be tested, use an oscilloscope to measure the level change time difference of each input and output port, and the change time difference is recorded as the transmission delay of the media data in the stage to be tested.

[0041] In specific practice, the stage to be tested includes: the digital-to-analog conversion device obtains Audio media stage, the Bluetooth device obtains Audio media stage, the 12S transmission stage, the Bluetooth ...

Embodiment 3

[0046] like image 3 As shown, an embodiment of the present invention also provides a media delay test device for an Android system, including:

[0047] The stage to be tested determination module 31 is used to determine the stage to be tested in the media data transmission process;

[0048] The test port setting module 32 is used for setting general input and output ports in the stage to be tested;

[0049] The level measurement module 33 is configured to measure the time difference of level change of the input and output ports when the media data reaches the stage to be measured, and the change time difference is recorded as the transmission delay of the media data in the stage to be measured.

[0050] In specific practice, the media data transmission process includes: a media data input stage and a media data output stage.

[0051] In specific practice, the level measurement module 33 measures the level change time difference of the input and output ports as follows: the le...

Abstract

The invention provides a media delay test method and device for an Android system, and the method comprises the steps: determining a to-be-tested stage in a media data transmission process; setting a universal input / output port in the to-be-tested stage; and when the media data arrives at the to-be-measured stage, measuring the level change time difference of the input / output port, and recording the change time difference as the transmission delay of the media data in the to-be-measured stage, thereby solving the problems of high cost, complex operation and great environmental influence in the measurement of the media delay through a sound sensor in the prior art.

Description

technical field [0001] The invention relates to the technical field of media delay testing, in particular to a media delay testing method and device for an Android system. Background technique [0002] With the development of society, in the field of Android (Android operating system) audio and video, people pay more and more attention to film and television effects; among them, avsync (audio and video synchronization) of media is an important parameter that directly affects the user's senses. In the prior art, avsync uses a sound sensor to measure the delay of Audio in an Android device. However, the traditional sound sensor is expensive and complicated to operate, and the test results are greatly affected by the environment. SUMMARY OF THE INVENTION [0003] Therefore, the technical problem to be solved by the present invention is to overcome the problems of measuring the media delay by sound sensors in the prior art, complex operation, and being greatly affected by the ...
