[ detailed description ] embodiments
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Referring to fig. 1, a flow chart of a set top box testing method according to an embodiment of the present invention is shown, in which the set top box testing method includes the following steps:
s1: determining a test value according to the basic operation boundary value;
the channel module of the multi-channel distributor in the set-top box is mainly used for filtering data in real-time code streams, and whether a design value meets the design value requirement given by a client or not needs to be evaluated after the product is designed, so that two boundary values of a test need to be set in the test, namely a basic operation boundary value and a basic damage boundary value. When the first boundary value is reached to basically damage the boundary value, the working system of the set-top box is out of work and can not work. In an exemplary embodiment, when the design value given by the customer is 32MB/s, the designer performs calculations using existing hardware equipment to set the basic operational boundary value to 27MB/s and the basic damage boundary value to 32 MB/s. The determination of the test value according to the basic operation boundary value in step S1 may be to use the basic operation boundary value as an initial value of the test, or may be to start the test after increasing or decreasing a step value according to the experience of the designer based on the basic operation boundary value.
S2: sending the test value to a test data stream sending server, and receiving a test data stream sent by the test data stream sending server;
s3: judging whether the received test data stream is correct, if so, adjusting the test value, and turning to the step S2; if not, returning the test value to the previous test value for retesting;
and judging whether the received test data stream is correct, specifically judging whether the test data stream sent by the server can be accurately received by the set top box at least once. For example, when the test value is set to 27MB/s, by determining whether 270 data can be received within 10s at this time, the test data stream is considered correct if possible, and incorrect if not. And adjusting the test value, specifically, setting an adjustment step length according to the interval between the basic operation boundary value and the basic damage boundary value, and adjusting the test value according to the step length. For example, when the basic operation boundary value and the basic destruction boundary value differ by 10MB/s, the adjustment step is set to 1MB/s, and when the basic operation boundary value and the basic destruction boundary value differ by 1MB/s, the adjustment step is set to 0.1 MB/s.
S4: judging whether the retest data flow is correct, and if so, setting the previous test value as an actual basic operation boundary value;
s5: continuously adjusting the test value, sending the adjusted test value to a test data stream sending server, and receiving the test data stream sent by the test data stream sending server;
s6: judging whether the received test data stream is correct or not, if not, returning the test value to the actual basic operation boundary value for retesting;
s7: if the retest result is correct, go to step S5; if the retest data stream is incorrect, the test value is set to the actual violation boundary value.
The above steps are further illustrated below with reference to specific examples: when the design value given by the customer is 32MB/s, the designer uses the existing hardware equipment to calculate and set the basic operation boundary value as 27MB/s and the basic damage boundary value as 32 MB/s. At this time, the difference between the two boundary values is 5MB/s, and the adjustment step size is set to be 1 MB/s. Meanwhile, 27MB/s is set as the initial value of the test, and 26MB/s or 28MB/s can be set as the initial value of the test according to the test requirement. Judging whether the received test data stream is correct or not, if not, indicating that the set top box has serious problems, and ending the test; if it is correct, the test value is adjusted up by one step to 28MB/s and the test is continued. Judging whether the received test data stream is correct again, if so, adjusting the test value up to 29MB/s by one step length, and continuing the test; if the data stream is incorrect, the received data stream can only reach the speed of 27.5MB/s, and obviously the currently sent data stream exceeds the bearing capacity of the channel module of the multi-channel distributor of the set top box, the test value is returned to the previous test value of 27MB/s for retesting, whether the retest data stream is correct is judged, and if the retest data stream is incorrect, the test is ended; if it is correct, indicating that the received data stream is restored to the normal speed of 27MB/s, it can be considered that the demultiplexer channel module has restored to the normal operation capability after adjusting the test value, so that the previous test value of 27MB/s is set as the actual basic operation boundary value. Continuously adjusting the test value, adjusting the test value up to 29MB/s by one step, continuously testing, judging whether the received test data stream is correct, if so, ending the test, and if not, returning the test value to the actual basic operation boundary value of 27MB/s for retesting; judging whether the received test data stream is correct again, and if so, finishing the test; if not, the demultiplexer channel module can be considered to have been corrupted at this point, and therefore 29MB/s is set to the actual corruption boundary value.
Fig. 2 is a system structure diagram of a set top box testing apparatus according to an embodiment of the present invention. The method comprises the following steps: the test system comprises a test boundary setting module 10, a test module 20, a test data adjusting module 30 and a test result judging module 40. Wherein,

and the test data adjusting module 30 adjusts the test value according to the judgment result of the test result judging module 40 and requests the test module 20 to send the test value to the test data stream sending server.
The test result judging module 40 judges whether the received test data stream is correct, if so, the test data adjusting module 30 is required to adjust the test value to continue the test, and if not, the test data adjusting module 30 is required to adjust the test value to return to the previous test value to retest;
judging whether the retest data flow is correct, if so, setting the previous test value as an actual basic operation boundary value, and if not, ending the test;
requiring the test data adjusting module 30 to continuously adjust the test value, determining whether the received test data stream is correct, if so, ending the test, and if not, requiring the test data adjusting module 30 to adjust the test value to return to the actual basic operation boundary value for retesting;
if the retest result is correct, the test data adjustment module 30 is required to continue adjusting the test value; if the retest data stream is incorrect, the test value is set to the actual violation boundary value.
In the testing process, firstly, a testing boundary setting module 10 presets a basic operation boundary value and a basic damage boundary value according to a data filtering design value of a multi-channel distributor channel of the set top box, a testing module 20 determines a testing value according to the basic operation boundary value preset by the testing boundary setting module 10, the testing value is sent to a testing data stream sending server, and a testing data stream sent by the testing data stream sending server is received, a testing data adjusting module 30 is matched with a testing result judging module 40, the testing module 20 is matched with the testing data adjusting module 30, the testing data adjusting module 30 adjusts the testing value according to a judging result of the testing result judging module 40, and the testing module 20 is required to send the testing value to the testing data stream sending server. The test result determining module 40 determines each test result and then directs the test data adjusting module 30 to adjust the test data according to the test result, so as to finally find the actual operation boundary value and the actual damage boundary value.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
