Said controlling computer is provided with index project that needs test and the instruction that controls of controlling said television receive terminal; Transmit data and give said digital television signal generator, the control command of transmit operation simultaneously carries out the frequency points corresponding setting for said television receive terminal;
Said controlling computer is obtained the view data of said television receive terminal output through image pick-up card, and with database in standard picture compare, record said digital television signal generator this moment data lower limit and lower limit performance index are set.
Concrete; Said control computer expert crosses the view data that image pick-up card obtains said television receive terminal output; And with database in standard picture compare, when meeting test request, said control computer can send the order that reduces the test image signal quality based on current test event and give said digital television signal generator; And continue the monitoring view data up to standard picture when inconsistent, record said digital television signal generator this moment data lower limit performance indications are set; Said control computer sends the order that improves the test image signal quality and gives said digital television signal generator; And continue the monitoring view data when just exceeding the index of range of receiving, record said digital television signal generator this moment data upper limit performance indications are set; Test the receptivity index test that can get into next channel after all combined test projects of a channel automatically, so repeat up to the receptivity index that tests all channels automatically.
Further; Said controlling computer selects to be connected with printer; Promptly can connect also and can not connect printer, after testing the test event of setting, said controlling computer can generate the test result of record the test report of a complete television reception performance index automatically according to set form; And compare with the index performance of standard, make sign to incongruent project automatically and distinguish.
Further, saidly control instruction and can obtain, and be transmitted to said television receive terminal and control, also can convert RS232 control command form to and send to said television receive terminal through remotely controlled.
Further; Receive the RF signal of said digital television signal generator transmission when said television receive terminal after; Image pick-up card begins to gather the LVDS or the CVBS picture signal of receiving terminal output and converts the PCIE data flow to and is sent to said controlling computer; Said controlling computer is reduced into view data to PCIE data flow decoding, and with database in standard picture compare.
The Auto-Test System of the intelligent high DTV receptivity parameter of the utility model has following advantage:
1, whole test process only need be carried out the selection of some test events in early stage, the back system can automatically controling of storage be instructed send, and accomplishes whole testing process automatically, provides examining report.
2, system can switch on different TV machine data platforms through the method for image comparison fast, accomplishes with to survey, and is compatible high, need not to be provided with multiple decoder driver, and simple to operate, test accurately.
Description of drawings
Fig. 1 is that the Auto-Test System data of the digital television signal that provides of the utility model embodiment transmit sketch map.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer, will combine accompanying drawing that the utility model is done to describe in detail further below.
As shown in Figure 1; The Auto-Test System of a kind of digital television signal that the utility model embodiment provides; Comprise tested television receive terminal, digital television signal generator, IMAQ card device, controlling computer; The input of wherein said television receive terminal is connected with the digital television signal generator, and output is connected with the IMAQ card device; Said controlling computer is connected with said television receive terminal, digital television signal generator, IMAQ card device respectively;
