[0029] figure 1 It schematically shows the flow chart of the TV HDCP encryption detection method according to the first preferred embodiment of the present invention.

[0030] like figure 1 As shown, the television HDCP encryption detection method according to the first preferred embodiment of the present invention comprises:

[0031] The first hardware verification step S11: connect the controller to the TV through a source channel supporting HDCP;

[0032] For example, the controller is a single chip microcomputer.

[0033] For example, the source channels supporting HDCP include HDMI source channels, DVI source channels, and DP source channels.

[0034] Second hardware verification step S12: the controller sends a set of data streams with HDCP encrypted information to the TV through a source channel supporting HDCP encryption, wherein the data streams do not contain any audio or video information;

[0035] That is to say, the data stream is just a simple data stream, no...

[0042] figure 2 It schematically shows a flow chart of a method for detecting HDCP encryption of a television set according to the second preferred embodiment of the present invention.

[0043] like figure 2 Shown, according to the TV set HDCP encryption detection method of the second preferred embodiment of the present invention comprises:

[0044] The first software verification step S21: connect the signal source device to the TV through the source channel supporting HDCP;

[0045] For example, the signal source device is the whole machine picture detection signal box.

[0046] For example, the source channels supporting HDCP include HDMI source channels, DVI source channels, and DP source channels.

[0047] Second software verification step S22: the signal source device sends a group of audio and video signals with HDCP encryption to the TV through the source channel, so that the TV can play images;

[0048] The third software verification step S23: the whole machine...

[0055] image 3 It schematically shows a flow chart of a TV HDCP encryption detection method according to the third preferred embodiment of the present invention.

[0056] like image 3 As shown, the TV HDCP encryption detection method according to the third preferred embodiment of the present invention includes:

[0057] The first direct detection step S31: scanning the unique code of the TV set;

[0058]For example, in the first direct detection step S31, the unique code of the TV may be scanned manually or automatically.

[0059] The second direct detection step S32: display the HDCP key on the TV screen according to the unique code of the TV;

[0060] For example, in the second direct detection step S32, through the network cable, infrared remote controller or USB remote controller, enter the factory menu to control the TV according to the unique code of the TV, so as to directly display the HDCP key on the TV screen.

[0061] The third direct detection step S33: using...

Abstract

The invention provides a direct detection HDCP encryption detection method for a television, comprising: a first direct detection step: scanning the unique code of the television; a second direct detection step: displaying the HDCP key on the television according to the unique code of the television on the screen; the third direct detection step: use the camera to take pictures of the image on the TV screen; the fourth direct detection step: identify the image captured by the camera through image recognition technology to identify the key in the image, and identify the The key in the image and the key in the database are compared; the fifth direct detection step: according to the comparison result, it is judged whether the HDCP encryption detection of the TV set is passed.

Description

technical field [0001] The invention relates to the field of television or display detection; more specifically, the invention relates to a television HDCP (High-bandwidth Digital Content Protection, high-bandwidth digital content protection) encryption detection method. Background technique [0002] At present, in China's TV manufacturing industry, when inspecting assembled TVs before leaving the factory, workers still use the method of testing each function of the TV one by one on the assembly line. Smart TVs have become the mainstream. Almost all TVs produced now carry communication ports such as Ethernet ports and USBs, which provide conditions for adjusting the communication between the host and the TV, and also allow automatic white balance adjustments to be realized. [0003] At present, production line workers are required to detect whether the TV HDCP programming is successful, and the existing HDCP encryption detection equipment is large in size and high in cost, w...
