Description
Technical Field
The invention relates to the technical field of signal processing, in particular to a switching analysis method of a signal source.
Background
In the prior art, a television generally supports inputs of various signal source interfaces, such as an ATV (analog television signal), a DTV (digital television signal), an HDMI (audio video signal), an AV (analog video signal), and the like. When using television, users often connect to a variety of input devices, such as ATV signal lines for analog television, PS4 for games, and DVD for movies.
When the user finishes watching the analog television and wants to play a game of PS4, the ATV signal source interface needs to be switched to the HDMI signal source interface on the television. In this case, if the speed of switching to the HDMI source interface is slow, the user experience is poor, and the tv performance is not good.
Therefore, the switching performance of the signal source interface is also an important index for television development. The code logic for switching the signal source interface is a complicated process. Taking a television of a logic chip as an example, a switching process of an ATV signal source interface to an HDMI signal source interface is shown in fig. 1, and as seen from fig. 1, the process is relatively long and involves a java layer, a c + + layer, a driver layer, or even a hardware layer, and the involved developers are at least four people (usually, one person is responsible for one module). If we want to optimize the switching speed of the signal source interface, we need to know which module needs to be optimized, and even which piece of code needs to be optimized.
At present, the time consumed by a certain process is calculated by printing to count the time consumed by each process, and then counting each data into a table. For example, when the ATV signal source interface switches the partial debug print of the HDMI1 signal source interface, a total time, for example, 0.436s (109.025s minus 108.589s, which is 0.436s), is consumed from the time when the button of the HDMI1 signal source interface is pressed to the time when the java layer tv service starts HDMI playback. Only a small part of the process of switching the HDMI1 signal source interface by the ATV signal source interface, rather than printing the complete process, we already see 7 data, and it needs to subtract the starting playing time 108.589s from the data to obtain the time consumed by the intuitive process.
Even worse, taking a tv supporting 1 ATV signal source interface, 1 DTV signal source interface, 3 HDMI signal source interfaces, and 1 AV signal source interface as an example, there are 12 groups of switching combinations of signal source interface channels in total. And for data accuracy, we usually test 5 times, and then average to obtain the final signal source interface switching performance result. Therefore, a complete test requires switching the signal source interface channel at least 60 times, and then counting the print data thousands of times. If the time of switching the signal source interface is required to be known, or whether the performance of switching the signal source interface is optimized by changing a code is required to be known, and side effects exist. If a complete data statistic is taken, it may take an engineer about 1 week if the printing is debugged by a manual statistic. This is a great challenge to human resource arrangement, and the development related to the signal source interface performance will progress very slowly.

In the codes of the television system, each module adds debugging printing at each code execution flow stage according to a uniform printing mark to generate a debugging printing report, then, an automation tool counts data according to the printing mark and outputs the result into a text, wherein the debugging printing report is exported in the form of the text; the average value of each stage data is statistically output in the form of a table.

In the above technical solution, in step S2, the print flag includes the currently switched signal source interface and/or the sub-phase executed by the current signal source interface and/or the execution time of the current sub-phase.
For example, the currently switched signal source interface refers to an "Operation" keyword to record which signal source interface is currently switched to; the sub-stage executed by the current signal source interface refers to the sub-stage recorded by the keyword 'Step' to which the current code stream is executed; the execution Time of the current sub-phase refers to the "Time" key that records when the sub-phase is executed.

In the above technical solution, in step S4, an analysis tool is used to analyze the debug print report.
For example, the parsing tool is written in the tv _ profile _ tool, which is written in the shell and/or phyton and/or java and/or c + + language, to parse the debugging print report.

step S46, judging whether the debugging printing report is scanned and finished;
if yes, go to step S47;
if not, returning to the step S43;
and step S47, dividing the data corresponding to the execution time of the current sub-stage in each data array by the operation times of the corresponding variable array, so as to obtain an average value of the data of each stage in each data array through statistics and output the average value.
In the above technical solution, as a preferred embodiment, taking an HDMI-to-HDMI 1 audio video signal interface as an example, the HashMap data array content of the 1 st scan is as follows:
| Operation | ATV->HDMI1 |
| count (counter) | 1 |
| TvSourceFragmentpressedUIbutton | 108.589 |
| stopTVplaystart | 108.636635 |
| tvserverstopTVplayend | 108.712952s |
| DroidLogicTvInputServicestarttuningsource | 109.025 |
| (more subsequent procedures) | (more follow-up data) |
(2) The HashMap data array content of the 2 nd scan is as follows:
before calculation:
after calculation:
(3) assuming that only 2 times of ATV cutting of an HDMI1 audio and video signal interface is performed, after debugging, printing and analysis are finished, the HashMap data array after average value calculation is:
wherein, the above-mentioned calculation mode is: and subtracting the data of the previous stage from the data of each stage, and dividing by the corresponding times of the count.
(4) The final text output result can be arranged into a table by excel, so that the time consumed by each stage of the operation of each signal source interface can be visually seen.
The analysis tool has no limit on the switching times of a certain signal source interface of a test plan, and can be combined randomly. For example, the ATV switches HDMI20 times, HDMI switches DTV 15 times, DTV switches AV 16 times, and AV does not switch ATV. According to the probability, the more the switching times, the more accurate the statistical result.
Furthermore, the work of automatically counting the switching data of the signal source interface is realized, the switching data of the signal source interface can be quickly and accurately provided, the data counting efficiency is greatly improved, and the research and development efficiency is further improved.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
