As an embodiment of the present invention, detection unit 83 is additionally operable to obtain the inspection under the detection classification according to detection classification Actual value is surveyed, and detection actual value is compared with the detection preset value to obtain the test result.
Fig. 9 is a kind of flow chart for detection method for audio/video decoding board that ninth embodiment of the invention provides, For convenience of description, only the parts related to the present invention are shown.
As an embodiment of the present invention, as shown in figure 9, the audio/video decoding board detection method includes the following steps:
In step S91, the identity information of the audio/video decoding board is read;
In step S92, is obtained according to the identity information and preset detection information, the default detection information includes signal The predetermined threshold value and video measurement standard picture sample of the channel classification of transmission and the correspondence parameter of the signal;
In step S93, the audio/video decoding board is detected according to the default detection information;
In step S94, after the whole test passes of channel, the KEY of authentication information is bundled with from the automatic burning of server;
In step S95, test passes through, and the examining report of generation is sent to production management system.
In the present embodiment, after channel whole test passes, detection host issues the software version pair toward server application It is that the authentication information for being bundled with audio/video decoding board software systems mandate, master chip are recognized using mandate to answer KEY, the KEY Information is demonstrate,proved, the memory of server based on data library issues the KEY for ensureing uniqueness, and detection host gets the KEY and enters its burning Audio/video decoding board board to be tested, and read board checking information and be sent to server and compare, if verification passes through, prompt to burn It records successfully, and by the SN of the audio/video decoding board of the burning KEY and the KEY associated records to server, the server It is different from production management system, is separate server, the KEY each used dedicated for management and control and retrospect.
Specifically, detecting host to server application KEY, and feed back audio/video decoding board board burning KEY to be detected Check information afterwards can connect progress communications with server by that will detect host, this is connected as cable network connection.
Presently preferred embodiments of the present invention is not intended to limit the invention, all within the spirits and principles of the present invention Made by all any modification, equivalent and improvement etc., should all be included in the protection scope of the present invention.
