Embodiment 1

[0057]figure 1 It is a flow chart of an audio automation testing method provided in Embodiment 1 of the present invention. This embodiment is applicable to detecting the performance of an audio chip, and the method can be executed by an audio automation testing terminal, which can use software and / or hardware way to achieve.

[0058] The method of Embodiment 1 of the present invention specifically includes:

[0059] S101. Control the set-top box to play the set audio signal, and control the audio collection device to collect the played audio.

[0060] Specifically, the set-top box may have an analog video signal built in, and the analog video signal includes an analog audio signal. The terminal sends a play request to the set-top box, controls the set-top box to play the video, and sends a collection request to the audio collection device, and controls the audio collection device to collect the analog audio signal. . In this embodiment, the audio collection device may use an...

Embodiment 2

[0074] figure 2 It is a flow chart of an audio automation testing method provided by Embodiment 2 of the present invention. Embodiment 2 of the present invention is optimized and improved on the basis of Embodiment 1, specifically including:

[0075] S101. Control the set-top box to play the set audio signal, and control the audio collection device to collect the played audio.

[0076] S102. Receive a time-domain audio signal sampled by the audio collection device.

[0077] S103. Convert the time-domain audio signal into a frequency-domain audio signal, acquire a frequency spectrum of the frequency-domain audio signal, and calculate the frequency and amplitude of the frequency-domain audio signal according to the frequency spectrum.

[0078] S104. Detect whether the frequency of the frequency-domain audio signal is within a preset range, and whether the amplitude of the frequency-domain audio signal exceeds a threshold, and obtain a detection result.

[0079] S105. Perform ...

Embodiment 3

[0083] image 3 It is a flow chart of an audio automation testing method provided by Embodiment 3 of the present invention. Embodiment 3 converts the time-domain audio signal into a frequency-domain audio signal on the basis of Embodiment 2, and obtains the frequency-domain audio The frequency spectrum of the signal, and the operation of calculating the frequency and amplitude of the frequency-domain audio signal according to the spectrum will be further described. like image 3 As shown, the third embodiment of the present invention specifically includes:

[0084] S101. Control the set-top box to play the set audio signal, and control the audio collection device to collect the played audio.

[0085] S102. Receive a time-domain audio signal sampled by the audio collection device.

[0086] S1031. Perform fast Fourier transform on the sampled time-domain audio signal to obtain a frequency spectrum of the transformed frequency-domain audio signal.

[0087] S1032. Extract a pl...

Abstract

The embodiment of the invention discloses an audio automatic testing method and terminal. The method comprises the steps of: controlling a set top box to play a set audio signal, and controlling audio acquisition equipment to acquire a played audio; receiving a time domain audio signal sampled by the audio acquisition equipment; converting the time domain audio signal into a frequency domain audio signal, acquiring a frequency spectrum of the frequency domain audio signal, and according to the frequency spectrum, calculating a frequency and an amplitude of the frequency domain audio signal; and detecting whether the frequency of the frequency domain audio signal is in a preset range and whether the amplitude of the frequency domain audio signal exceeds a threshold, and acquiring a detection result. By the technical scheme of the invention, an error and misjudgment which are caused by manual operation can be effectively prevented, detection accuracy is high, detection efficiency is effectively improved, and production cost is saved.

Description

technical field [0001] The embodiments of the present invention relate to the field of automated testing, and in particular to an audio automated testing method and terminal. Background technique [0002] A set-top box is a device that connects a TV set to an external signal source, converts signals transmitted by cable, satellite antenna, broadband network, and terrestrial broadcasting into TV content, and displays them on the TV set. The transmitted signals include not only analog signals such as images and sounds, but also digital signals such as web pages and subtitles. In the production line of set-top boxes, the huge production volume leads to the failure of timely detection of faulty set-top boxes, which will increase the after-sales pressure after entering the market and affect the corporate brand image. In particular, the performance problem of the audio chip of the set-top box is not easy to detect. Because the ground pad of the audio chip has no ground connection...
