Abstract
The invention discloses a method for automatically acquiring digital program information, which can acquire detailed program information of all TS (transport stream) streams at one time without a code stream analysis tool, provides an efficient method for analyzing digital signals for designers, greatly saves the cost of a code stream analysis process, and comprises the steps of firstly accessing external storage equipment on a digital television, acquiring the whole package information of program signals of all programs by using the program search function of the digital television, then analyzing the whole package program information acquired by the television in a software decoding mode to obtain the detailed program information of each program, finally automatically converting the analyzed detailed information of all programs into a text file, outputting the text file to the external storage equipment, and opening the file so as to acquire all the detailed information at one time.
Description
Technical Field
The invention relates to the field of digital audio and video, in particular to a method for automatically acquiring digital program information.
Background
With the global popularization of digital televisions, export countries of digital television products in China are more and more, the export number is more and more increased, the systems of overseas digital television signals are various and are continuously updated and developed, and r is ATSC, ISDB, DVBT2, DVBC, DVBS2 and the like, so that the digital television signal data of all regions of all target countries in the world are collected and analyzed in time, and the method becomes an indispensable precondition for the research and development of overseas digital television products. It is important to accurately and completely parse the detailed data of the local real-time tv signal in the shortest possible time in front of a large amount of signal data, so as to provide the necessary support for the designer.
However, in the existing methods for acquiring program information of a digital television, a code stream needs to be recorded first, and then specific programs are analyzed one by one through a specific code stream analysis tool, so that specific program information such as PID, VID, AID and the like of a single program is obtained. The method has the following defects: 1) a recording tool is needed to record a single code stream, and the code stream recording tool is high in cost, heavy and inconvenient to carry; 2) a single TS stream needs to be analyzed through a code stream analysis tool, and the code stream analysis tools corresponding to signals with different analysis systems are different and cannot be used universally; 3) the detailed program information of one code stream can be analyzed at one time, and the efficiency is not high enough.
Disclosure of Invention
The present invention is directed to a method for automatically acquiring digital program information, so as to solve the above-mentioned problems.
The above object of the present invention is achieved by the following technical solutions:
a method for automatically acquiring digital program information, comprising the steps of:
s1, FULL search is carried out on the local program on the digital television, the program signal whole packet signals of all programs are stored in Database, and if no program data exists, the setting value is null;
s2, accessing an external storage device on the digital television;
s3, starting an automatic analysis function by operating OSD;
s4, the television operating system scans the peripheral interface of the television, when detecting that the available external storage equipment is accessed, the next step is carried out, otherwise, the scanning is continued for 5 times, and no external storage equipment is accessed through OSD feedback;
s5, automatically creating a text file; automatically creating a text file by software coding outside, setting a parameter variable flag1 in CADE, if flag1 is marked as true, successfully creating the file, starting a function of analyzing the whole package information of the program signal, if flag is marked as false, failing to create the file, exiting from creating, and returning to step S3 until success;
s6, automatically analyzing the whole package information of the program signal, firstly reading the structural data of the whole package of the program information stored in the Database, then analyzing the detailed information data of each program one by one, extracting useful data which accord with the setting from all the data obtained by analysis, then capturing the extracted analyzed data of each program, writing the data into the created text file, then reading the current system time and writing the current system time into the text file together, setting a parameter variable flag2 in the CODE after the writing is finished, starting the close file function if the flag2 is marked as true, successfully outputting the detailed information of all the programs, and feeding the detailed information back to a user through the OSD, otherwise, failing to write the data, and feeding the detailed information back to the user through the OSD.
In conclusion, the invention has the following beneficial effects:
the scheme can avoid using a code stream burning tool and a code stream analyzing tool, greatly saves the cost of the analysis process, can automatically acquire the detailed information of all programs at one time, greatly improves the analysis efficiency, is easy to realize software, has strong universality for a digital television, and is convenient for cross-scheme platform transplantation.
