Detailed Description

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

At present, all be equipped with the IR receiving head in the STB, can receive the instruction signal of remote controller transmission, in operation, infrared remote controller is with original key code signal (as shown in fig. 1), through 37.9KHz signal modulation (as shown in fig. 2), send for infrared signal through infrared emitting diode conversion, after infrared signal was received to the IR receiving head, through processing such as demodulation filtering, restore the code value to the original key code signal that has not modulated, through the decoding of main chip SOC, obtain the code value definition of button.

The set-top box further comprises an IR terminal to which an extension cord is connectable, one end of the extension cord being provided with an infrared receiving head. If the IR receiving head of the set-top box is blocked, for example, the set-top box is placed behind a television or in a television cabinet, the IR receiving head of the set-top box is blocked when receiving infrared rays, at the moment, the set-top box can be connected to an IR terminal of the set-top box through an IR extension line, and the function of receiving infrared rays by the set-top box is realized through the IR extension line and the IR terminal.

In order to ensure the function of the set-top box for receiving infrared, the infrared receiving functions of the IR receiving head and the IR terminal need to be tested, because the SOC of the set-top box receives unmodulated original key code value signals from the IR receiving head and the IR terminal, if the sources cannot be distinguished by the simultaneous test, the traditional test method must be divided into two steps for testing.

The method comprises the following steps: the system block diagram for testing the IR receiver head of a set-top box is shown in FIG. 3, where the IR terminal is not connected to an extension line. The tester presses a remote controller KEY, such as KEY1, the set-top box IR receiving head receives a modulated KEY code value signal, the modulated KEY code value signal is sent to the set-top box SOC after demodulation processing, the KEY description KEY1 is obtained after SOC decoding, the KEY description KEY1 is displayed on a Television (TV) through a video interface, and whether the infrared receiving function of the IR receiving head is normal or not is judged through KEY1 displayed on the TV.

Step two: the system block diagram of the testing set top box IR terminal is shown in FIG. 4, at this time, the IR terminal is connected with an infrared extension line, an IR receiving head of the set top box prevents the set top box from receiving infrared signals through shielding measures, it is ensured that a remote controller KEY1 signal is received through the IR terminal, the set top box IR terminal receives a modulated KEY code value signal, the modulated KEY code value signal is sent to the SOC of the set top box after demodulation processing, a KEY description KEY1 is obtained after SOC decoding, the KEY description KEY is displayed on a TV through a video interface, and whether the infrared receiving function of the IR terminal is normal is judged through KEY1 displayed.

However, this conventional test method has the following disadvantages:

1. by operating the remote controller to send out the infrared signal, the receiving of the set-top box is easily interfered, thereby influencing the result judgment, for example, when a plurality of set-top boxes are tested simultaneously.

2. The testing of the IR receiver head and IR terminals of the set-top box is performed twice separately, which is inefficient.

3. The tester carries out subjective judgment on the test result through television display, and a plurality of set top boxes need to be displayed in a plurality of ways, so that the tester is difficult to test the plurality of set top boxes simultaneously.

In order to solve the above problems, an embodiment of the present application provides an automatic testing system for infrared reception of a set top box, which can automatically identify the set top box, automatically send a remote control code value, automatically process and feed back a result, and does not require a tester to press a remote controller or a tester to subjectively compare, and an IR receiving head and an IR terminal can be simultaneously connected for testing, so that the testing process is not easily interfered, the efficiency is high, and the result reliability is high.
