The specific embodiment of the apparatus for processing program information according to the present invention is substantially the same as the following embodiments of the method for processing program information, and will not be described herein again.
Referring to fig. 2, a first embodiment of the processing method of program information according to the present invention provides a processing method of program information, where the processing method of program information includes:
step S1, acquiring a terrestrial digital television broadcasting DTMB signal.
In this embodiment, firstly, the DTMB signal of the terrestrial digital television broadcasting is the area information to which the operator is added, specifically, this embodiment packs the area information of the current operator in the SI/PSI data of the program provided by the operator, encodes and multiplexes the VIDEO _ PES and AUDIO _ PES of each program and the SI/PSI data into one TS stream signal, further modulates the TS stream signal into a radio frequency signal, and sends out the radio frequency signal through a transmitter, where the radio frequency signal is the DTMB signal. The SI is short for service Information, PSI is program Specific Information, and SI/PSI data includes various Information, such as program name, TV station name, various PID, private Information, and even data is transmitted separately to realize data communication.
The processing apparatus for program information in this embodiment may receive the DTMB signal through the signal receiver after being started, so as to obtain the DTMB signal with the area information and the program information.
And S2, identifying the area information in the DTMB signal.
In this embodiment, after receiving the DTMB signal, the processor 1001 in the processing apparatus of the program information demodulates the received DTMB signal into a TS stream signal, and decomposes the VIDEO _ PES, AUDIO _ PES, and SI/PSI data codes after parsing and multiplexing the TS stream signal, where the SI/PSI data codes are region information of a current operator packed for each program, so as to identify the region information in the DTMB signal. The regional information refers to regional information of operators, and the operators comprise a central-broadcast movie and television central office, a provincial broadcasting and television bureau (modified places are the broadcasting and television bureau and a station or a group), a city broadcasting and television, and a district and county broadcasting and television. In this embodiment, the DTMB signal with the area information is identified, and if the information in the signal is not identified, the DTMB signal without the area information is deleted or processed.
And S3, deleting the repeated program information in the DTMB signal according to the area information.
In this embodiment, the program information in the DTMB signal is compared according to the area information in the DTMB signal identified in step S2, and because the types of operators are various, different operators issue the same program information, and in order to avoid the trouble of the user caused by the repeated programs received by the television, the repeated television program information needs to be deleted.
For example, one digital television receives two repeated programs of the Hunan satellite television, wherein one of the two repeated programs is the A satellite television with the area information A sent by the broadcasting and television bureau of province A, and the other one is the A satellite television with the area information B sent by the broadcasting and television bureau of province B. Therefore, if the embodiment is a television set in city C of province B, the purpose of deleting repeated programs can be achieved by deleting the satellite television a sent by the central office of radio and television a; if the television is located in D city of province A, the purpose of deleting repeated programs can be achieved by deleting the satellite television A sent by the radio and television central office of province B. Of course, in the actual use process, the signal strength of the two areas can be detected, and then the program information with weaker signals can be deleted.
According to the method for processing the program information, provided by the embodiment of the invention, the DTMB signal with the area information is obtained, and the DTMB signal with the repeated program content is deleted according to the area information, so that the repeated program information contained in the DTMB signal is deleted, each television station only corresponds to one piece of program information, and the problem that a user is troubled by the repeated program content all the time is solved.
Further, referring to fig. 3, the method for processing program information according to the present invention provides a method for further deleting repeated program information in step S3 in the first embodiment, and based on the embodiment shown in fig. 2, the step of deleting repeated program information in the DTMB signal according to the area information includes:
and step S31, acquiring the position information of the program terminal.
In this embodiment, the GPS positioning set in the processing apparatus of the program information obtains the position information of the program terminal through the GPS positioning, and can also obtain the real-time position information of the program terminal through the beidou positioning and the like. In addition, the position information with fixed preset value can be further arranged in the processing device of the program information, the equipment can be sold in a setting area, and the terminal position can be positioned through a terminal network or manually selected and set by a user through a UI (user interface). The terminal position acquired in practice is not limited to the manner of acquiring the terminal position of the program mentioned in the present embodiment.
Step S32, determining the area information in the DTMB signal and the location information of the program terminal.
In this embodiment, the processor 1001 of the apparatus for processing program information compares the area information in the acquired DTMB signal with the position information acquired by GPS positioning, and determines that the data indicating the area position contains the same position data segment, that is, the same area is considered to be contained, and performs the corresponding operation according to the comparison result.
Specifically, if the comparison result in step S32 is that the area information in the acquired DTMB signal is not the same as the position information acquired by GPS positioning, the following step S321 is executed.
Step S321, deleting the repeated program information not belonging to the program terminal location information in the DTMB signal.
In this embodiment, in the processor 1001 of the apparatus for processing program information, according to a result that area information in the acquired DTMB signal is different from location information acquired by GPS positioning, deletion processing is performed on corresponding program information that does not include the same location data segment.
Specifically, if the comparison result in step S32 is that the area information in the acquired DTMB signal is the same as the position information acquired by GPS positioning, step S322 is executed.
Step S322, determining the acquisition time of each program information in the DTMB signal.
In this embodiment, according to a result that area information in the acquired DTMB signal is the same as position information acquired by GPS positioning, acquiring time stored when the DTMB signal with the same comparison result is acquired by the processing device of the program information for the first time, and further comparing the sequence of the acquiring time.
And step S323, deleting the repeated program information with later acquisition time in the DTMB signal.
For the same television program, the earlier the television receiving time is, the better and stronger the signal of the corresponding program is. Therefore, in this embodiment, according to the result of the acquisition time of the DTMB signal in step S322, the program information with the same repeated program in the later acquisition time is deleted.
For example, if a digital tv receives two duplicate E views, where one E view receives 23. The actual acquisition time is compared with the DTMB signal sent by the operator acquired in the same time period.
In this embodiment, by providing a method for further deleting repeated program information by deleting the repeated program information in the DTMB signal according to the area information, the repeated program of the DTMB signal that does not belong to the program terminal position information is deleted, and the DTMB signal with a better signal and the DTMB signal with a fast transmission frequency are stored, so that the problems of watching a program with repeated signals and weak signals are solved.
Further, referring to fig. 4, a second embodiment of the processing method for program information according to the present invention provides a processing method for program information, and based on the embodiment shown in fig. 3, the processing method for program information further includes:
step S401, acquiring administrative region information of the program terminal according to the position information of the program terminal.
In this embodiment, the processing device of the program information stores the administrative region information of the country or region where the user is located in the memory 1005 in advance, and the processor 1001 in the processing device of the program information acquires the administrative region information that the program terminal belongs to and is determined according to the GPS positioning position acquired in step S31. Certainly, the administrative region information of the country or region where the user is located may not be preset in the processing device of the program information, or the position information of the program terminal may be obtained according to GPS positioning and then the administrative region information of the position information may be searched from the network, and in practice, all the ways of obtaining the administrative region information of the program terminal according to the position information of the program terminal belong to the ways of obtaining the administrative region information of the program terminal in the present invention.
Step S402, arranging the DTMB signals after the repeated program information is deleted from near to far according to the administrative region information to which the program terminal belongs.
In this embodiment, according to the stored administrative area information belonging to step S401, the location data of the GPS positioning is compared with the area information of the DTMB signal from which the repeated program information is deleted, and the program information from which the repeated program information is deleted, which contains more pieces of the same location data, is arranged in front of each other according to the difference between the administrative area division data of the province and the city.
The television users generally pay priority to the real-time programs in the area. For example, two different television programs received by the television are a television program transmitted by the radio and television central office in F city and a program transmitted by the radio and television central office in G province, where F city is under the administrative jurisdiction of G province, and specifically, if the television is located in F city in G province, the television programs transmitted by the radio and television central office in F city are arranged in front and the television programs transmitted by the radio and television central office in G province are arranged in back. The actual arrangement of the DTMB signals from which the repeated program information is deleted from the near to the far according to the administrative domain information to which the program terminal belongs is not limited to the manner mentioned in the embodiment.
In step S403, the aligned DTMB signal is output.
In this embodiment, by providing a method for processing program information, according to the distance between the area information of the DTMB signal after deleting the repeated program information and the administrative area relationship to which the program terminal location information belongs, the program information related to the program information is pushed in a front arrangement manner, and the problem that a user watches television programs in an area of interest more is solved.
Referring to fig. 5, a third embodiment of the processing method of program information according to the present invention provides a processing method of program information, which based on the above embodiment shown in fig. 2, includes:
in step S501, position information set by a user is acquired.
In this embodiment, the processor 1001 of the apparatus for processing program information receives target location information input by a user, and compares the target location information with a location data segment of area information in the DTMB signal for deleting duplicate program information. For example, the user may set location information different from that of GPS positioning according to the need or preference. The position to be set in practice is not limited to this case, and may be set according to different conditions.
Step S502, according to the position information set by the user, the program information which is the same as the position information set by the user is screened out from the DTMB signal after the repeated program information is deleted.
In this embodiment, according to the comparison result in step S501, the program information with the deleted duplicate program information having the same position data segment is screened out.
For example, the television user inputs the location information H city, and the television set screens out all the programs in the television from which the repeated programs have been deleted, which are television programs sent by the radio and television in H city. In practice, the program information can be screened by inputting provinces, cities and regions of different countries or regions.
In step S503, the screened DTMB signals are arranged and output in front.
In the method for processing program information provided in this embodiment, a user screens program information of a target location through a region, so as to achieve the purpose of pushing a program in a selected region where the user pays attention to, and solve the problem that the user spends time searching for the program in the selected region.
Referring to fig. 6, a fourth embodiment of the processing method of program information according to the present invention provides a processing method of program information, which based on the above embodiment shown in fig. 2, includes:
step S601, a keyword input by a user is acquired.
In this embodiment, the processor 1001 of the apparatus for processing program information receives a keyword input by a user, and compares the keyword information with a data segment of a program information keyword in the DTMB signal for deleting duplicate program information. The keywords can be program classification vocabularies with certain significance, such as entertainment, news, sports and the like.
Step S602, program information related to the keyword is screened out from the DTMB signal after the repeated program information is deleted according to the keyword, wherein the related program information refers to program information containing the keyword.
And screening out the program information containing the same keyword data and deleted with repeated program information according to the comparison result in the step S601.
In step S603, the screened DTMB signals are arranged and output in front.
In the method for processing program information provided in this embodiment, by obtaining the keyword input by the user, the program information of the selected content is screened out according to the preference of the user on the basis of deleting the repeated program, and the problem of consuming time to find a favorite program is solved.
Referring to fig. 7, a fifth embodiment of the processing method of program information according to the present invention provides a program information sorting, which is based on the above embodiment of the program information filtering in fig. 1, and the processing method of program information includes:
in step S701, the history playing frequency of each program information is acquired.
In this embodiment, the processing apparatus for program information acquires data of program information broadcast stored in the memory 1005, where the data of program information broadcast is stored in real time, and a corresponding data statistics module counts the broadcast times of the program every time the program is broadcast, and by comparing the broadcast times of the program information, the program information corresponding to the broadcast times of the program information is sequentially screened out according to the sequence of the times.
Step S702: and arranging the DTMB signals from which the repeated program information is deleted from high to low according to the frequency.
Generally, the watching frequency of the favorite television programs is higher, so that the favorite programs are arranged in front for the convenience of searching for the favorite programs by the user. For example, in the television program sequence of a certain user in I city, the sequence of the television program is that the I satellite watches before the J satellite, but in the history playing program in the television of the user, the J satellite watches the record N times per week, the I satellite watches M times per week, N is larger than M, and when the television program is watched next time, the television arranges the J satellite before the I satellite and outputs the J satellite. The specific arrangement principle is not limited to the playing frequency of the program information exemplified in the embodiment.
The embodiment provides a program information processing method, which realizes that programs with higher playing frequency are prioritized and pushed according to program history records played by the programs by counting the playing times of the programs, and solves the problem that a user needs to spend time to search programs concerned by the history.
