Abstract
The utility model provides a digital audio frequency test device of a digital television set-top box, which is characterized by comprising a digital audio frequency decoding plate, wherein the digital audio frequency decoding plate is supplied with electric power by a power supply, and is respectively connected with a digital audio frequency output interface of a digital television set-top box and an AV audio frequency port of a digital television through digital audio frequency wires. The digital audio frequency test device has the advantages of reducing the cost of invested equipment, greatly shortening the occupied space, leading tests to be simpler and more convenient with high efficiency, further guaranteeing the consistency and high-quality of tests, and seldom generating the false judgments.
Description
[technical field]
The utility model relates to a kind of communication equipment field, particularly a kind of digital audio testing equipment of digital TV set-top box.
[background technology]
The digital audio interface of digital TV set-top box is used for transmitting audio data, makes the audio frequency of set-top box output more clear, interesting to listen to.The test equipment needed thereby instrument and the material category of digital TV set-top box digital audio interface were more in the past, and the amplifirer that all must be linked into the audio frequency specialty is tested, wherein audio power amplifier generally all huger, account for that station and efficient are lower, cost is higher, the erroneous judgement situation also appears easily.
[utility model content]
The technical problems to be solved in the utility model is to provide a kind of digital audio testing equipment of digital TV set-top box, has not only reduced the cost of used device, and has dwindled institute greatly and take up space.
The utility model is achieved in that a kind of digital audio testing equipment of digital TV set-top box, comprise a digital audio decoding plate, this digital audio decoding plate is powered by a power supply, and this digital audio decoding plate is connected with the digital audio output interface of digital TV set-top box and the AV audio port of Digital Television respectively by the digital audio line.
The digital audio testing equipment of above-mentioned digital TV set-top box also comprises a toggle switch, and this toggle switch is connected with described digital audio decoding plate.
Also be provided with an indicator light on the described digital audio decoding plate.
The interface that described digital audio decoding plate is connected with digital TV set-top box, and the interface that is connected with Digital Television is provided with anti-misoperation device.
Advantage of the present utility model is: adopt the digital audio decoding plate to test, no matter manually, still all saving cost aspect the equipment input; And whole testing equipment takes up space and dwindles greatly; Maintenance of equipment is simple, makes and tests more simple and fast, efficient is higher, maintenance cost is low; Also guarantee the consistency and the quality of test in addition, the erroneous judgement situation seldom occurred.
[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is a structural representation of the present utility model.
[embodiment]
See also shown in Figure 1, the digital audio testing equipment 10 of digital TV set-top box of the present utility model, comprise a digital audio decoding plate 1, a 5V power supply 2 and a toggle switch 3, this digital audio decoding plate 1 is by described 5V power supply 2 power supplies, and this digital audio decoding plate 1 is connected with the digital audio output interface 22 of digital TV set-top box 20 and the AV audio port 32 of Digital Television 30 respectively by digital audio line 4, and this toggle switch 3 is connected with described digital audio decoding plate 1.Also be provided with an indicator light (not shown) on the described digital audio decoding plate 1.The interface that described digital audio decoding plate 1 is connected with digital TV set-top box 20, and the interface that is connected with Digital Television 30 is provided with anti-misoperation device (not shown).
Operation principle of the present utility model is: the digital audio and video signals of the digital TV set-top box 20 output digital audio decoding plate 1 by described digital audio testing equipment 10 is decoded into simulated audio signal, be input to again in the television set speaker 34 of Digital Television 30, judge by the sound of television set speaker 34 output whether the digital audio output of digital TV set-top box 20 is normal again, thereby reach the effect that digital audio and video are tested simultaneously.
Specific operation process is as follows:
1, on request described digital audio decoding plate 1 and the digital audio output interface 22 of digital TV set-top box 20 and the AV audio port 32 of Digital Television 30 are connected, insert the 5V power supply again;
2, have under the digital audio output state and can on television set speaker 34, hear the sound in described digital TV set-top box 20;
3, stir described toggle switch 3 and carry out the switching of the dissimilar interfaces of digital audio (optical fiber interface or coaxial interface);
4, judge by television set speaker 34 output sounds whether the digital audio output of digital TV set-top box 20 is normal, EOT.
In sum, digital audio testing equipment of the present utility model mainly adopts the digital audio decoding plate to test, and this digital audio decoding plate hardware designs is simple, small and exquisite, and indicator light is clear; 5V power supply power supply is simple, and it is little that a whole set of testing equipment is taken up space, and is very easy to use on very limited product lineman position, space, and maintenance of equipment is simple; No matter, still all saving cost aspect the equipment input manually; Make and test more simple and fast, efficient is higher, maintenance cost is low; Also guarantee the consistency and the quality of test in addition, the erroneous judgement situation seldom occurred.
