Embodiment 1

[0025] According to an embodiment of the present invention, a method embodiment of a method for detecting a multi-tuner set-top box is provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions , and, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0026] figure 1 It is a flow chart of an optional multi-tuner set-top box detection method according to Embodiment 1 of the present invention, such as figure 1 As shown, the method includes the following steps:

[0027] Step S102, the processor sends a first instruction to the set-top box under test, wherein the set-top box under test includes N tuners, N is a natural number greater than or equal to 2, the first instruction is used to switch the set-top box under test to the Mth tuner,...

Embodiment 2

[0063] According to an embodiment of the present invention, an embodiment of a detection device for a multi-tuner set-top box is also provided, image 3 It is a schematic diagram of an optional multi-tuner set-top box detection device according to Embodiment 2 of the present invention, such as image 3 As shown, the device includes:

[0064] The first sending unit 40 is used to send the first instruction to the set-top box under test, wherein the set-top box under test includes N tuners, N is a natural number greater than or equal to 2, and the first instruction is used to switch the set-top box under test to the Mth tuner , and make the set-top box under test play the signal program of the Mth tuner, where M is a natural number less than or equal to N.

[0065] Specifically, N is a natural number, for example, N is 4, that is, the set-top box under test has 4 tuners. When N is equal to 4, M can be any natural number from 1 to 4. The first instruction that the processor sen...

Embodiment 3

[0087] An embodiment of the present invention provides a detection system for multi-tuner set-top boxes. Figure 4 It is a structural diagram of an optional multi-tuner set-top box detection system according to Embodiment 3 of the present invention, such as Figure 4 As shown, the system includes:

[0088] Processor 20 and test motherboard 30, processor 20 sends the first instruction to the set-top box under test, the first instruction is used to switch the set-top box under test to the Mth tuner, and make the set-top box under test play the signal program of the Mth tuner, Processor 20 receives the first reply instruction returned by the set-top box under test according to the first instruction, and determines the switching result according to the first reply instruction. When the switching result is that the switching is successful, processor 20 sends the second instruction to the test mainboard 30, and the test mainboard 30 collects the real-time parameters of the Mth tune...

Abstract

The invention discloses a detection method, device and system for a multi-tuner set top box. The method includes the following steps: a processor sends a first instruction to a to-be-tested set top box, wherein the to-be-tested set top box includes N tuners, N is a natural number greater than or equal to 2, the first instruction is used for enabling the to-be-tested set top box to be switched to the M tuner and enabling the to-be-tested set top box to play signal programs of the M tuner, and M is a natural number smaller than or equal to N; the processor receives a first replay instruction returned by the to-be-tested set top box, and determines a switching result according to the first replay instruction; if the switching result shows that switching succeeds, the processor sends a second instruction to a test mainboard, wherein the second instruction is used for controlling the test mainboard to collect real-time parameters of the M tuner of the to-be-tested set top box; and the processor determines a detection result of the M tuner of the to-be-tested set top box according to a second replay instruction returned by the test mainboard. The detection method, device and system help to solve the technical problems of the prior art that the production test efficiency is low since only a single tuner interface can be tested during detection of a multi-tuner set top box.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a detection method, device and system for a multi-tuner set-top box. Background technique [0002] According to the signal source, set-top boxes can be divided into satellite set-top boxes, terrestrial set-top boxes and cable set-top boxes. The corresponding set-top box Tuner interface is DVB-S, DVB-T, DVB-C Tuner. Some countries and regions often have multiple signal sources, including satellite signals, terrestrial signals, and cable signals. Set-top boxes equipped with multiple tuners can receive signals from multiple satellites at the same time, or receive satellite and terrestrial or cable signals at the same time. This type of set-top boxes is very popular among consumers and has become popular. In the factory production test process, each tuner interface needs to test audio and video decoding, voltage value, 22K waveform, short circuit protection and other...
