Abstract

The invention relates to the field of automation testing, in particular to an OTT set top box testing method. The method comprises the steps of video and audio testing and remote control reception testing. According to the method, the quality of a produced set top box can be judged by processing and analyzing video and audio signals output by an HDMI; the mode of using a program for controlling a remote control to transmit remote control signals is used for replacing the mode of manually pressing the remote control to transmit the signals, meanwhile the set top box can receive the signals synchronously, after the set top box receives the remote control signals, the signals are decoded into key values for judging whether the set top box can receive the signals correctly, and finally the purpose of detecting the quality of the function of the set top box and the remote control can be achieved.

Description

A kind of product test method of OTT Set Top Box
Technical field
The present invention relates to automatic test field, relate in particular to a kind of product test method of OTT Set Top Box.
Background technology
Along with the fast development of the Internet, the concept of wired home is just progressively familiar with by people, and wherein, the product taking intelligent TV set as main body is to form wired home most critical, a most important part.And adopted the OTT Set Top Box of Android system, give full play to wired and wireless network technology family's high definition movie theatre, TV online, amusement and game are brought in the parlor in the front yard of getting home, thereby improved people's quality of life level.Wherein, OTT Set Top Box product tape is still embodied on the sense organ of HD video, audio frequency to the main function of people.
The OTT Set Top Box of Android system is depending on mainly having adopted on, Audiotechnica, HDMI looks, Audiotechnica.In process of production, just need to test to guarantee that the network performance of product and user are in the experience depending on bringing user on, audio frequency to the parameter index depending on, audio frequency and additional wired, radio function.
In addition, traditional test mode is artificial by button, and whether observation television has the quality of making correct action and judge remote controller and set box remote control signal receiver.
In order to ensure the reliability of the Set Top Box quality of producing, meanwhile, improve efficiency aborning, just must design a kind of functional test scheme that is directed to Set Top Box, so that improve conforming product rate.
Summary of the invention
The object of the present invention is to provide a kind of product test method of OTT Set Top Box, solve OTT Set Top Box in process of production to looking, the test of the parameter index of audio frequency and additional wired, radio function not comprehensively, inaccuracy, cause the problem that Qualified Products Rate is low.
For addressing the above problem, the technical solution used in the present invention is:
A product test method for OTT Set Top Box, be divided into look, audio-frequency test and remote controller receive test;
The described method depending on, audio-frequency test comprises the following steps:
Put up test environment, PC end and OTT Set Top Box are interconnected by HDMI line and netting twine; Make one section of video with 1KHz sound; Issuing video playback order at PC end makes Set Top Box start to play the video of making; PC end is controlled the vision signal and the voice signal that use video frequency collection card to gather HDMI output, and with the video that predefined optimum Set Top Box the is play analysis that compares; Utilize based on Zernike matrix picture similarity contrast algorithm, the particular frame of every Set Top Box HDMI output and the static images that getting married and start a new life property Set Top Box captures are before carried out to the contrast of picture analogies degree; If static images contrast frame number, in allowed band, carries out video flowing test; If video frame number in allowed band, displaying video collected sound signal, and utilize Fourier transform scheduling algorithm to convert frequency to, whether the frequency simultaneously getting by judgement approaches 1Khz, it is qualified in certain allowed band, to determine whether;
The method that described remote controller receives test comprises the following steps:
By PC auto-control equipment, remote controller is carried out to actuation of keys, remote controller by button after, OTT Set Top Box is received corresponding key assignments signal decoding, decoded key assignments is back to PC within a certain period of time, PC judges the accurate signal whether this signal receiving is made for remote controller corresponding signal for OTT Set Top Box, all buttons on repeated presses remote controller, if PC receives that signal and signal are judged as correctly at the appointed time, for remote controller signal reception is qualified.
Further technical scheme is, described in look, in the method for audio-frequency test, video flowing test adopts the quantity statistics of DirectShow technology achieve frame.
Further technical scheme is, control device receives in the method for test, and described automation equipment is tool control single chip computer, and the PIN on tool control single chip computer is for answering the button on remote controller and with order, button being pressed.
Adopt the beneficial effect that produces of technique scheme to be: the present invention can be by processing, analyze the quality that just can judge institute's production Set Top Box product to HDMI output depending on, audio signal; Launch to replace manually by the remote signal of program control remote controller and transmit by the button of remote controller, simultaneously, Set Top Box can be synchronous acknowledge(ment) signal, Set Top Box is received after remote signal, become key assignments to judge the signal of receiving that can Set Top Box correct signal decoding, finally to reach the object that detects Set Top Box and remote-controller function quality.
Brief description of the drawings
Fig. 1 is the looking of product test method, the audio testing method schematic flow sheet of a kind of OTT Set Top Box of the present invention.
Fig. 2 is that the remote controller of the product test method of a kind of OTT Set Top Box of the present invention receives method of testing schematic flow sheet.
