Referring to fig. 1, in order to improve the efficiency of testing the set-top box, in an embodiment of the present invention, a set-top box testing apparatus includes:

the control circuit is respectively connected with the output end of the wired communication component, the output end of the video signal access component and the output end of the network port component;

the control circuit is used for outputting a network port test trigger signal to a network port of the set top box through the network port component when receiving the access signal so that the set top box outputs the network port test signal through the network port when receiving the network port test trigger signal;

the network port component is also used for receiving a network port test signal transmitted by the network port of the set top box and outputting the network port test signal to the control circuit;

the control circuit is also used for uploading a set top box network port normal signal to an external terminal through the wired communication component when the network port test signal is determined to be consistent with the preset network port signal, and outputting a video test trigger signal to the set top box through the network port component so that the set top box outputs a test video signal through the video interface;

the video signal access assembly is used for receiving a test video signal transmitted by a video interface of the set top box and outputting the test video signal to the control circuit;

and the control circuit is also used for uploading the normal signal of the video interface of the set top box to an external terminal through the wired communication component when the test video signal is determined to be consistent with the preset video signal.

In this embodiment, the wired communication component may include a wired communication chip and a priority communication interface electrically connected to the wired communication chip, and the wired communication chip and the corresponding communication interface may be selected according to a required bus, for example, "CAN bus, RS-485 bus, RS-232 bus", and the like, so that the wired communication component CAN establish a bus communication connection with an external terminal, thereby implementing uploading of data to the external terminal through the wired communication component, or receiving of data transmitted from the external terminal.

In this embodiment, the network port component may be implemented by using a network port chip and a network port connector electrically connected to the network port chip, and the network port connector may be implemented by using a "crystal head", and one end of the network port connector may be electrically connected to the network port chip by using a network cable. When the network port connector is inserted into the network port of the set-top box, the network port chip can automatically detect that the current network port connector is inserted into the network port of one set-top box and can output an access signal to the control circuit. When receiving an access signal, the control circuit outputs a network port test trigger signal to the set-top box through the network port chip to trigger the set-top box to start executing a preset network port function detection program, if the network port function of the set-top box is normal at the moment, a network port test signal is returned through the network port of the set-top box and transmitted to the control circuit through the network port connector, the network cable and the network port chip, if the control circuit can normally receive the network port test signal and is consistent with the preset network port signal, for example, the received network port test signal is '1111', the preset network port signal is '1111', the normal network port function of the current set-top box can be judged, and the normal network port signal of the set-top box is uploaded to an external terminal through the wired communication assembly, so that the external terminal records the current network port test result. The network port test signal prestored in the set top box can be set by research personnel, the preset network port signal can be set by the research personnel and prestored in the test device of the set top box, and when the network port function of the set top box is normal, the network port test signal actually output by the set top box and the preset network port signal are the same signal. It can be understood that, if the network port function of the set-top box is faulty, the network port component in the set-top box testing device may not receive any signal transmitted from the network port of the set-top box, that is, the control circuit may not receive the network port test signal, or the actual network port test signal received by the control circuit through the network port component is inconsistent with the preset network port signal, and then the control circuit may determine that the network port component of the set-top box is faulty, and may upload the network port fault signal of the set-top box to the external terminal through the wired communication component, so that the external terminal records the network port fault of the current set-top box, and prompts a tester in front of the external terminal to stop testing, and places the fault testing board in a to-be-maintained area to wait for subsequent maintenance.

In this embodiment, the control circuit may be implemented by using a main control chip, for example, S905X 2. The video signal access assembly can be realized by adopting a video signal receiving chip and a video signal connector electrically connected with the video signal receiving chip, the types of the video signal receiving chip and the corresponding video signal connector can be selected according to the type of a video interface on the set top box to be tested, for example, the video signal receiving chip of an 'AV interface, an HDMI interface and a DP interface' can receive a test video signal transmitted by the video interface of the set top box, the test video signal is output to a main control chip in a control circuit after being subjected to digital processing, and the main control chip uploads a normal signal of the video interface of the set top box to an external terminal through a wired communication assembly when the test video signal is determined to be consistent with a preset video signal.

Specifically, referring to fig. 2, in an embodiment, the video interface of the set-top box includes an HDMI interface and an AV interface, the test video signal includes an HDMI video signal, an AV video signal, and an AV audio signal, the preset video signal includes a preset HDMI signal, a preset AV video signal, and a preset AV audio signal, and the video signal access component includes:

the input end of the HDMI component is connected with an HDMI interface of the set-top box, and the HDMI component is used for receiving an HDMI video signal and outputting the HDMI video signal to the control circuit;

the input end of the AV component is connected with an AV interface of the set-top box, and the AV interface is used for accessing an AV video signal and an AV audio signal and outputting the AV video signal and the AV audio signal to the control circuit;

the control circuit is also used for uploading a normal HDMI signal of the set top box to an external terminal through the wired communication component when the HDMI video signal is determined to be consistent with the preset HDMI signal;

and the control circuit is also used for uploading the normal signal of the AV interface of the set-top box to an external terminal through the wired communication component when the AV video signal is determined to be consistent with the preset AV video signal and the AV audio signal is determined to be consistent with the preset AV audio signal.

In this embodiment, when it is determined that the network port test signal is consistent with the preset network port, that is, when it is determined that the network port function of the set-top box is normal, the main control chip outputs the video test trigger signal to the set-top box through the network port component, so that after receiving the video test trigger signal, the set-top box outputs an AV video signal and an AV audio signal through an AV interface of the set-top box, and simultaneously outputs an HDMI video signal through an HDMI interface of the set-top box.

In this embodiment, the AV component includes an AV left channel audio connector, an AV right channel audio connector, an AV video receiving circuit, and an AV video signal connector electrically connected to the AV video receiving circuit, and the AV video receiving circuit, the AV left channel audio connector, and the AV right channel audio connector are all electrically connected to the main control chip. The AV video receiving circuit may employ an AV video signal processing chip to receive an AV video signal and perform digital processing, and then output the AV video signal to the main control chip, as can be seen from the above, the main control chip may employ S905X2, and S905X2 may directly perform similarity analysis on the received AV video signal and the preset AV video signal, and if the two signals are consistent, it may be determined that the AV video interface in the AV interface of the current set-top box is normal in function. Meanwhile, the main control chip can also directly receive AV audio signals transmitted by the set-top box through the ADC module by the AV left channel audio connector and the AV right channel audio connector, wherein the AV audio signals comprise a left channel AV audio signal and a right channel AV audio signal, and the two signals are the same signal in a preset test program of the set-top box. When the control circuit confirms that the frequency and the amplitude of the left channel AV audio signal are consistent with the preset AV audio signal and confirms that the frequency and the amplitude of the right channel AV audio signal are consistent with the preset AV audio signal, the control circuit can confirm that an AV sound interface in an AV interface of the set top box is normal. At this moment, the main control chip uploads a normal signal of the set top box AV interface to the external terminal through the wired communication assembly, so that the external terminal displays and records the current test result. In practical application, the AV video signal and the AV audio signal which are prestored in the set-top box are set by research personnel, and when an AV interface of the set-top box is normal, the AV video signal which is actually output by the set-top box is consistent with the preset AV video signal and the AV audio signal which is actually output by the set-top box is consistent with the preset AV audio signal. It can be understood that, if the AV audio signal actually received by the set-top box is not consistent with the preset AV audio signal and/or the AV video signal actually received by the set-top box is not consistent with the preset AV video signal, the main control chip uploads the set-top box AV interface fault signal to the external terminal through the wired communication component, so that the external terminal displays and records the current test result, and prompts the current tester to suspend the test.

Similarly, in this embodiment, the HDMI component includes an HDMI receiving circuit and an HDMI connector electrically connected to the HDMI receiving circuit, the HDMI connector can be connected to the HDMI receiving circuit through a connecting wire, the HDMI receiving circuit can digitize the HDMI video signal received by the HDMI connector and output the signal to the main control chip, so that the main control chip performs similarity analysis on the received HDMI video signal and the preset HDMI video signal, and if the two signals are consistent, if the HDMI of the current set-top box is normal, the main control chip uploads a normal signal of the HDMI of the set-top box to an external terminal through the wired communication component, and if the HDMI of the current set-top box is not normal, the master control chip can confirm the failure of the HDMI interface of the current set-top box and upload the failure signal of the HDMI interface of the set-top box to the external terminal through the wired communication component, so that the external terminal displays and records the current HDMI test fault of the set top box, and prompts the current tester to suspend the test.

Referring to fig. 3, in an embodiment of the present invention, the set-top box testing apparatus further includes:

the control circuit is also used for transmitting a test infrared signal to an infrared receiving component of the set top box through the infrared transmitting component when the network port test signal is determined to be consistent with the preset network port signal, so that the set top box outputs an infrared receiving signal through the network port of the set top box when receiving the test infrared signal;

and the control circuit is also used for uploading a normal signal of the infrared receiving component of the set top box to an external terminal through the wired communication component when the infrared receiving signal output by the network port of the set top box is received through the network port component.

In this embodiment, the infrared transmitting component can be implemented by an infrared transmitter, and the control circuit controls the infrared transmitter to transmit a test infrared signal to the infrared receiving component of the set-top box after confirming that the network port function of the set-top box is normal. If the infrared receiving component of the set-top box is normal at the moment, the set-top box starts to execute a preset infrared test program when receiving the test infrared signal, and feeds back an infrared receiving signal prestored in the infrared test program from the network port of the set-top box, at the moment, the control circuit receives the infrared receiving signal through the network port component and confirms that the infrared receiving component of the current set-top box is normal, and then the infrared receiving component normal signal of the set-top box is uploaded to an external terminal through the wired communication component, so that the external terminal records that the infrared function of the current set-top box is normal.

It can be understood that, if the infrared receiving component of the set-top box fails, the set-top box cannot normally receive the test infrared signal, and at this time, the control circuit cannot receive the infrared receiving signal, so that the current failure of the infrared receiving component of the set-top box can be confirmed, and the failure signal of the infrared receiving component of the set-top box is uploaded to the external terminal through the wired communication component, so that the external terminal displays and records the current failure of the infrared receiving component of the set-top box, and prompts current testers to suspend testing.

Through the arrangement, the automatic testing of the infrared function of the set top box can be realized, the infrared receiving assembly of the set top box does not need to be tested independently, and the testing efficiency of the set top box is improved.
