Detailed Description
In order to make the technical problems solved, technical solutions adopted and technical effects achieved by the present invention clearer, the technical solutions of the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Fig. 1 is a flowchart illustrating a program information processing method according to an embodiment of the present invention. The method of the present embodiment may be performed by a processing apparatus of program information, wherein the apparatus may be implemented by software and/or hardware, and may be generally integrated in a digital television set-top box or a digital television set-top box. As shown in fig. 1, the method may include:
s110: and recording the program information after acquiring the recording instruction of the user.
The program information in this embodiment is preferably a television show program, and may also be a variety program or a talk show program.
For example, the user may send a program recording instruction through a recording module in the playback device. The recorded program may be a program currently being played or a program to be played several days later. If the program is the program which is currently played, when the playing equipment receives a program recording instruction, the program recording function is started immediately. If the program is a program to be played after several days, the playing device will automatically start the program recording function when the program starts to be played. It should be noted that, as soon as the playing device starts recording the program, the recorded program information will be completely stored in the external storage device that is in communication connection with the playing device. The external storage device may be a usb disk or a mobile hard disk.
S120: and analyzing the audio information and the video information of the program information, and identifying interference information irrelevant to the current plot in the program information according to an analysis result.
The interference information unrelated to the current scenario may be an advertisement inserted before the formal broadcasting of each episode of program, a beginning of a title of each episode of program, an end of a title of each episode of program, and some contents repeatedly broadcasted between the two episodes of program for program transition. The presence of the above-mentioned interference information seriously affects the experience of the user in watching the program, for example, when the above-mentioned interference information is played, generally, the user manually triggers a program fast forward command through a remote controller to skip the interference information, so that the user can continue to watch the program content.
Illustratively, since the interference information is different from the effective information in the program information except the interference information in audio signals and video images, the interference information can be automatically identified by adding an audio and video information processing module in the software of the playing device.
Specifically, taking a television series as an example, when each episode of the television series formally starts playing, an episode number of the television series appears on the display interface, and at this time, no sound signal generally exists. Thus, when the above situation is detected, it may be indicated that the content of the series will formally start playing, and any audio information and video information in the past (e.g., advertisements, titles, etc.) may be identified as disturbing information.
For another example, when each episode of a television show ends, there is usually a play of an end-of-title, and when the end-of-title is played, subtitles such as names of actors or operators behind the scenes related to the television show are synchronously displayed on the display screen, and the background color of the subtitles is usually kept unchanged. The trailer and associated subtitle information may be identified as disturbing information since it prevents the user from watching the next episode of the television series continuously.
In summary, based on the unique characteristics of the audio information and the video information in the interference information, the interference information irrelevant to the current scenario in the program information can be identified.
S130: and deleting the interference information, and performing synthesis processing on information except the interference information in the program information as effective information.
The information except the interference information in the program information is used as effective information to be synthesized, so that coherent and uninterrupted played program information can be obtained. When the user watches the program information, the requirement of continuously watching the program can be met without manual operation, and the experience of the user is improved.
The embodiment of the invention provides a program information processing method, which records program information after acquiring a recording instruction of a user, and can identify interference information irrelevant to a current plot in the program information according to an analysis result by analyzing audio information and video information of the program information. By deleting the interference information and synthesizing the information except the interference information in the program information as effective information, the recorded program information can be played continuously, the requirement of a user for continuously watching programs is met, and the user experience is improved.
Example two
Fig. 2 is a flowchart illustrating a program information processing method according to a second embodiment of the present invention. In this embodiment, two pairs of embodiments one are optimized, and referring to fig. 2, an embodiment two of the present invention specifically includes:
s210: and recording the program information after acquiring the recording instruction of the user.
S220: analyzing the audio information of the program information, judging whether the audio signal exists in the current program information within a set time period, if so, continuing to execute the judgment operation of the step S220 until the audio signal does not exist in the current program information is identified; otherwise, step S230 is performed.
For example, in a tv series, in general, in the process of playing the tv series, episode numbers, such as a first episode and a second episode, are displayed in a display before the content of each episode of the tv series is formally played. At this time, the image in which the episode number is located is in a still state, and there is generally no synchronized playback of the audio signal. Therefore, based on the above features, and in a manner of combining the audio information and the video information, it is possible to effectively identify whether or not the target time period in which the audio signal does not exist is a time period in which the episode number is displayed. If so, the starting point of the target time period can be used as the starting moment of playing the television play; otherwise, the program information played in the target time period can be indicated as effective information related to the scenario in the television scenario, but not interference information such as advertisements or titles and the like.
S230: the time period in which the audio signal is not present is taken as the target time period.
S240: analyzing the video information of the program information, judging whether an episode number related to the program information exists in the video information in a target time period, and if so, executing a step S250; otherwise, step S260 is performed.
It should be noted that, the audio information and the video information for analyzing the program information are not sequentially classified, and may be executed synchronously or sequentially. If the video information of the program information is analyzed first, the time period of the episode number related to the program information may be determined first, and then it may be determined whether an audio signal exists in the time period, and if no audio signal exists, the start point of the time period may be used as the start time of the program information. After the start time of the program information is determined, the information before the start time can be determined as the interference information such as the advertisement or the title song.
S250: the process proceeds to step S270 with the start point of the target time slot as the start time of the program information.
S260: and taking the video information in the target time period as effective information.
S270: video information and audio information before the start time are set as interference information for each episode program corresponding to the episode number.
In this embodiment, the target for identifying the interference information is each episode of program, that is, the program information to be recorded is divided into multiple episodes of program information according to the episode number. The processing method has the advantages that the interference information in each set of programs can be effectively identified, the comprehensiveness of the interference information identification can be improved, and the phenomenon of missing identification is avoided.
S280: and deleting the interference information, and performing synthesis processing on information except the interference information in the program information as effective information.
The valid information in step S280 is information other than the interference information in the program information, and therefore includes the valid information determined in step S260.
In the second embodiment, based on the above embodiment, by analyzing the audio information and the video information of the program information, the interference information irrelevant to the current scenario in the program information is effectively identified, and the interference information mainly includes the advertisement, the title song, and the like inserted before the program is formally played. For each set of programs, after the interference information is identified and deleted, the information except the interference information can be used as effective information to be synthesized, so that the requirement of a user on continuously watching the programs is met, and the user experience is improved.
EXAMPLE III
Fig. 3 is a schematic flow chart of a program information processing method according to a third embodiment of the present invention, where the third embodiment of the present invention optimizes the above-described embodiments, and referring to fig. 3, the third embodiment of the present invention specifically includes:
s310: and recording the program information after acquiring the recording instruction of the user.
S320: and analyzing the video information of the program information, and determining the detection time interval of the caption information which is played in a sliding mode in the video information according to the analysis result.
Still taking television shows as an example, during the playing of the television shows, at the end of each episode of the television shows, the subtitle information that is played in a sliding manner will generally appear in the display interface for displaying other information related to the television show besides the scenario, such as names of actors in the television show and workers behind the scenes. The playing of the slide subtitle is generally accompanied by the playing of the trailer, and when the playing of the trailer is completed, the subtitle content is also displayed. In the process of displaying the subtitle information, the background color of the display picture is generally kept unchanged, for example, black or light orange, so that based on the above characteristics, and by adopting a video information identification technology, an image feature identification method and other methods, whether the content played in the detection time period in which the subtitle information played in a sliding manner exists is the title of the tv series can be judged, and if yes, the identified title is used as the interference information; otherwise, the content of the detection time interval is used as effective information related to the television scenario for subsequent synthesis processing.
S330: during the detection period, each frame of image in the video information is extracted, and the step S340 is continuously performed.
S340: identifying whether the background color of each frame of image is consistent, if so, executing step S350; otherwise, step S360 is executed.
For example, the step may be based on an image recognition algorithm, to classify the foreground portion and the background portion of the image, and further to identify the color of the background portion.
S350: the video information and the audio information within the detection period are taken as the interference information, and the process proceeds to step S370.
S360: and taking the video information and the audio information in the detection period as effective information.
S370: and deleting the interference information, and performing synthesis processing on information except the interference information in the program information as effective information.
Third, on the basis of the above embodiments, by identifying whether the detected time period of the subtitle information that is slidingly played exists in the program information is the time period of playing the trailer of the program information, the identified trailer can be used as the interference information, and by deleting the interference information, the synthesis processing of the subsequent effective information can be guaranteed, so that the user is prevented from manually deleting the interference information, and the effect of improving the user experience is achieved.
It should be noted that the solutions provided in the third embodiment and the second embodiment are parallel solutions, and may be executed sequentially or synchronously.
Example four
Fig. 4 is a flowchart illustrating a program information processing method according to a fourth embodiment of the present invention, where the fourth embodiment is optimized based on the foregoing embodiment, and further identifies invalid information that is repeatedly played in the program information, and deletes the invalid information. Referring to fig. 4, the fourth embodiment of the present invention specifically includes:
s410: and recording the program information after acquiring the recording instruction of the user.
S420: and analyzing the audio information and the video information of the program information, and identifying interference information irrelevant to the current plot in the program information according to an analysis result.
S430: and deleting the interference information.
S440: and respectively collecting video information of the set frame number of the ending part of the previous episode of the program and the starting part of the next episode of the program for two adjacent episodes of the program according to the episode number related to the program information.
Illustratively, still taking television shows as an example, each episode of a television show in the program information may be located according to the episode number. In the above embodiment, the identification of the interference information such as the first episode, the advertisement, the last episode and the like is already completed, and the deletion of the interference information is completed, so that after the playing of each episode is completed, the played episode is the episode number of the episode. Therefore, by identifying the display time of the episode number, the ending part of the program of the previous episode and the starting part of the program of the next episode can be determined. The beginning part and the ending part can be embodied by time periods, preferably, the first 5 minutes for identifying the episode number display is taken as the ending part of the previous episode program, and the last 5 minutes for completing the episode number display is taken as the beginning part of the next episode program.
For example, for the video information played at the end part of the previous episode of the program and at the beginning part of the next episode of the program, the data of all the image frames in the video information may be collected separately, and of course, the video information with the set frame number may also be extracted therefrom.
S450: for each frame image in the video information with the set frame number, the similarity of each frame image in the previous set of programs and each frame image in the corresponding next set of programs is compared, and the step S460 is continuously executed.
S460: judging whether the similarity reaches a set ratio, if so, executing step S470; otherwise, step S480 is executed.
S470: and taking the video information with the set frame number in the next set of program and the corresponding audio information as invalid information, deleting the invalid information, and continuing to execute the step S490.
For example, if the similarity of each frame image in the previous set of programs compared with each frame image in the corresponding next set of programs reaches a set ratio, it indicates that the content played at the beginning of the next set of programs is the same as the content played at the ending of the previous set of programs, that is, the video information is played repeatedly. Therefore, after the playing information of the starting part of the next set of programs is deleted as the invalid information, the requirement of continuously watching the programs by the user can be further met, and the user experience is improved.
S480: the video information with the set frame number in the next set of program and the corresponding audio information are used as the effective information except the interference information in the program information, and the step S490 is continuously executed.
S490: and synthesizing the information except the interference information in the program information as effective information.
On the basis of the above embodiment, in the program information, some invalid information that is repeatedly played in two adjacent sets of programs is further identified and deleted, which provides a guarantee for realizing continuous playing of the program information, so that a user does not need to skip the repeated information through manual operation when watching the program, and user experience is improved.
