Abstract
The invention provides a method for testing receiving performance of a digital TV receiving terminal in the field of digital TV receiving terminal testing, comprising the following steps: connecting a digital TV transmitter to the digital TV receiving terminal, test starts after the digital TV receives terminal receiving TV signal from the digital TV transmitter; a central processor issues a channel searching command to the digital TV tuning chip; the digital TV tuning chip searches some TV channel with fixed-frequency; if channel searching is successful, the test pass, or else executes the next step; back to the former step, renewedly searching at least once, if channel searching is successful, the test pass, or else fails. The method of the invention realizes scan for a fixed frequency, thereby improving speed for testing TV receiving function of the digital TV receiving terminal, which further saves testing time and effectively improves testing efficiency.
Description
Technical field
The present invention relates to the method for testing of digital television devices field tests, particularly receiving performance of digital television receiving terminal.
Background technology
In the production of receiving terminal for digital television (as digital TV, mobile TV etc.), the television reception performance detection step of terminal is absolutely necessary.What adopt at present is to detect by the way that direct reception is play, and two kinds of detection modes are arranged usually:
A kind of is wireless mode: with the antenna or an external reception antenna of receiving terminal for digital television itself, receive in progress digital television program, if can receive TV signal and can normal play, just think that the television reception performance of terminal is normal, otherwise for not passing through.Concrete steps are as follows:
1) opens transmitter and play TV programme;
2) adjust the reception antenna of terminal, if external telescopic antenna need pull it, if want external antenna to need external antenna is connected;
3) open receiving terminal for digital television, press TV function of search key and begin search;
4) if can search the TV programme menu, then press play button and play;
5) as searching the TV programme menu and can playing, just think that the television reception performance is qualified;
Maybe can not play as not searching for or search for, just think television reception performance inconsistency lattice less than program.
Another kind is wired mode: connect the antennal interface or the antenna measurement interface of transmitter and television terminal with a radio frequency cable, if can receive TV signal and can normal play, just think by, otherwise for not passing through.Concrete steps are as follows:
1) connects antennal interface or the antenna measurement interface of transmitter with a radio frequency cable to television terminal;
2) open transmitter and play TV programme;
3) open receiving terminal for digital television, press TV function of search key and begin search;
4) as searching the TV programme menu, then press play button and play;
5) if can also can play by the searching TV program menu, just think that the television reception performance is qualified; Maybe can not play as not searching for or search for, just think television reception performance inconsistency lattice less than program.
These two kinds of methods all are to adopt the mode that directly receives broadcast to detect, though relatively simple, all exist following shortcoming:
Because during the first received television program of television receive terminal, need carry out full frequency band scanning, some frequency range comprises tens channels, as UHF (ultra high frequency, hyperfrequency) frequency range comprises 49 channels, and whole frequency scans down consuming time very long, has caused the low of testing efficiency.
In sum, adopt traditional detection method, will produce above-mentioned shortcoming in actual applications, therefore need to improve method of testing, in the hope of improving the speed and the efficient of test receiving terminal TV functions for the television receiving function of receiving terminal for digital television.
Summary of the invention
Problems such as the test length consuming time that exists in the method for testing at the TV functions of above-mentioned existing receiving terminal for digital television, test speed is slow, testing efficiency is not high the purpose of this invention is to provide the method for a kind of effective raising receiving terminal for digital television television receiving function test speed and efficient.
The present invention is achieved in that
A kind of method of testing of receiving performance of digital television receiving terminal, this Digital Television include central processing unit and Digital Television tuning chip, it is characterized in that, this method comprises:
Step 1, connect digital TV transmitter and receiving terminal for digital television, after receiving terminal for digital television receives TV signal from digital TV transmitter, the test beginning;
Step 2, central processing unit send the channel search order to the Digital Television tuning chip;
Step 3, Digital Television tuning chip are searched for the television channel of a certain fixedly frequency; If the channel search success, then test is passed through, otherwise execution in step four;
Step 4, return step 3 and search for again at least once, if the channel search success, then test is passed through, otherwise test crash.
Described method in any once test of step 3 or step 4, if test is passed through, then shows test prompt for successful information on terminal screen, if test crash, the then information of demonstration test crash on terminal screen.
Described method connects digital TV transmitter and adopts wireless mode to be connected with receiving terminal for digital television in the described step 1.
Described method connects digital TV transmitter and adopts wired mode to be connected with receiving terminal for digital television in the described step 1.
Among the present invention, in the software of digital TV terminal receiving equipment, increase the TV functions self-test module of a digital TV terminal.Use method of the present invention, can realize to one fixedly frequency search for, test the television reception performance of receiving terminal for digital television fast, thereby saved the testing time greatly, improve production test efficient effectively, be suitable for test use in the digital TV terminal production in enormous quantities.
