Echo cancellation test method and system for TV audio collection device

Abstract

The invention relates to a method and a system for testing echo cancellation of a television audio acquisition device. The television audio acquisition device comprises one or more audio acquisition devices. The method comprises the steps that sound source analog signals are inputted into a signal converter; the signal converter outputs a first path of analog signals which is not converted and a second path of digital signals which is acquired by converting the sound source analog signals; the television audio acquisition device receives the first path of analog signals and the second path of digital signals, wherein the first path of analog signals is received by the audio acquisition devices; and whether the first path of analog signals and the second path of digital signal from the sound source analog signals are cancelled or not in output signals of the television audio acquisition device is detected. The testing method provided by the invention realizes detection for an echo cancellation function of the television audio acquisition device without being matched with a television through simulating communication between the television and the audio acquisition device.

Description

technical field [0001] The present invention relates to an audio testing method and system for a TV audio collection device, and in particular to a method of simulating communication between a TV and an audio collection device, so as to realize audio collection of a TV without a matching TV A detection method and system for the echo cancellation function of a device. Background technique [0002] The audio collection device used on the TV is usually assembled together with the image collection device into a TV camera device (TV Camera). For example, a common TV camera device generally includes a camera, a microphone, a signal processor, a connection interface, etc. The TV camera device can be connected to the TV through a wired or wireless connection, so that the TV camera device can communicate with the TV. The camera of the TV camera device is used to collect image information, and the microphone is used to collect audio information. After the collected image information ...

AI Technical Summary

Problems solved by technology

[0005] However, on the production line of the TV camera device, the TV camera device cannot communicate with the TV, so it cannot be ensured whether the audio collection device of the TV camera device on the production line has a normal echo cancellation function

If the TV is placed on the production line and the echo cancellation field test of the audio collection device of the TV camera device is carried out, the production cost will be greatly increased, and the operation is inconvenient

In addition, in the prior art, there is no fixture for conveniently positioning the TV camera device with the audio collection device in the echo cancellation test
