Fig. 3 is a flowchart illustrating a method of processing preview information according to an exemplary embodiment. The application scope and execution subject of the processing method of the schedule information, for example, the method is used for the intelligent device 110 of the implementation environment shown in fig. 1. As shown in fig. 3, the method may be performed by the smart device 110 and may include the following steps.
In step 310, according to the code stream issued by the front end, the current/subsequent program information and the program list carried by the code stream are obtained.
The front end may be a control system at the operator side, such as a broadcast/television transmission code stream system, and may be a front end device in the implementation environment shown in fig. 1, such as a tuner and a demultiplexer. The front end issues a transmission code stream to the intelligent device 110, and the intelligent device 110 obtains the video file to be played, the current/subsequent program information and the program list contained in the transmission code stream by analyzing the code stream.
The current/subsequent program information refers to PF (present/following) information, that is, the current and next program information to be played, so that a user can conveniently view the current program information and the next program information to be played. The program list refers to schedule information, and is used to carry information of a longer time period, for example, the program list may include information of programs to be played in the last week.
It should be noted that, the code stream issued by the front end generally carries PF information and schedule information. The smart device 110 may attempt to acquire PF information and schedule information carried in the codestream.
In step 330, when the program list is successfully obtained and the current/subsequent program information is updated, whether the same event identifier exists under the channel number in the program list is searched according to the channel number indicated by the current/subsequent program information and the corresponding event identifier.
It should be explained that due to an operation error or a front-end device, the PF information and the schedule information are missed, or the front-end device sometimes does not issue the schedule information directly, so the following three situations often occur: (1) only PF information and no schedule information exist in the code stream. (2) There are channels for which PF information is missing in the schedule information. (3) Individual program information is missing from the schedule information.
The current/subsequent program information is updated, which means that the content of the current broadcast program and the next broadcast program of a channel is changed. The channel number refers to the name or number of each television channel, such as "center one", "center two", "Hunan Wei" or "Shanghai Wei" or the like. The event identifier corresponding to the channel number refers to the number of the event occurring in the channel where the channel number is located. Each event identification (event ID) has a corresponding event, which means that the currently playing program is xxx and the next playing program is YYY.
It should be noted that the PF information carried in the code stream may include the program content currently being played and the program content to be played next in each channel. For example, the program content currently played by the "central station" is AAA, the program content to be played next is BBB, the program content currently played by the "central station" is CCC, and the program content to be played next is DDD. For the second case, it is assumed that schedule information exists in the code stream, but PF information of some channels in the schedule information is missing. The intelligent device 110 successfully acquires the schedule information from the code stream, and checks whether the same event ID exists in the schedule information under the corresponding channel number according to the channel ID and the event ID in the PF information when monitoring that the PF information is changed.
In step 350, if the same event identifier does not exist under the channel number in the program list, the current/subsequent program content corresponding to the event identifier in the current/subsequent program information is obtained.
It should be explained that the current/subsequent program information includes a channel number, an event identification, and current/subsequent program content. The current/subsequent program content may be currently played or program information to be played next, such as program name, program type, program broadcasting time, and the like.
Specifically, according to the channel number (channel ID) and the event ID in the PF information, if the same event ID does not exist under the corresponding channel number in the schedule information, the current/subsequent program content corresponding to the event ID in the PF information is acquired, that is, what program is currently played and what program is played next on the channel corresponding to the channel number can be obtained from the PF information.
In step 370, the current/subsequent program content is supplemented to the channel number of the program list to obtain the new program announcement information.
It should be noted that, because the same event ID does not exist under the corresponding channel number in the schedule information, it can be considered that the channel corresponding to the channel number in the schedule information lacks the currently played program information and the next played program information. Therefore, the intelligent device 110 supplements the current/subsequent program content obtained from the PF information to the channel number of the schedule information, and obtains new program announcement information with more complete information constituted by the schedule information.
The new notice information is referred to as the latest generated notice information, that is, EPG (electronic program guide), relative to the notice information (original notice information) that has been cached locally by the smart device 110.
In the technical solution provided by the above exemplary embodiment of the present invention, when the program list is successfully acquired and the current/subsequent program information is updated, according to the channel number and the corresponding event identifier indicated by the current/subsequent program information, whether the same event identifier exists under the channel number in the program list is searched, so as to determine whether the current/subsequent program information corresponding to the channel exists in the program list, and when the event identifier does not exist, the current/subsequent program content corresponding to the event identifier is supplemented to the program list, so that more complete new program announcement information can be obtained, the defect that the electronic program guide is incomplete due to the fact that the current/subsequent program information of some channels does not exist in the program list is overcome, the present invention can provide a more complete electronic program guide, therefore, the user can quickly select the channel program which the user wants to watch.
In an exemplary embodiment, as shown in fig. 4, the method for processing the announcement information of the program provided by the present invention may further include the following steps:
in step 410, if the acquisition of the program list carried by the code stream fails, acquiring locally cached original program announcement information;
since the code stream may only contain PF information and does not contain schedule information, the acquisition of schedule information from the code stream fails. When the schedule information is failed to be obtained from the code stream, locally cached program forecast information, namely the original program forecast information, is obtained.
In step 430, according to the channel number indicated by the current/subsequent program information, the current/subsequent program content carried by the current/subsequent program information is supplemented under the channel number corresponding to the original program announcement information, so as to obtain the new program announcement information.
When the code stream has no schedule information, the current/subsequent program content corresponding to the channel number is supplemented under the channel number in the cached original program forecast information to obtain new program forecast information.
In an exemplary embodiment, as shown in fig. 5, the method for processing the announcement information of the program provided by the present invention may further include the following steps:
in step 510, if there is a vacancy in the new program announcement information, determining a channel and a time period corresponding to the vacancy position;
the absence means that some channels in the new announcement information have no announcement for some time period. That is, it is not known what programs will be broadcast on these channels during these time periods, so there is no filling of program content and there is a vacancy. Aiming at the vacancy in the new program forecast information, the channel and the time period corresponding to the position of the vacancy can be obtained. That is, it is determined to which time period of which channel the vacancy of the program content is not filled.
In step 530, retrieving program content in the time slot several days before and after the channel in the new program announcement information;
wherein, the days before and after can be two days before and after, three days before and after or more. Assuming that the channel corresponding to the vacant position is 'one center', and the corresponding time period is 8: 00-10: 00 of 16 #, the two days before and after 16 # are 14 #, 15 #, 17 # and 18 #. The intelligent device 110 can be two days before and after the channel of 'one center' in the new program announcement information, namely program contents of No. 14, No. 15, No. 17 and No. 18: 00-10: 00. The program content may be a program name.
In step 550, if the program contents of the channel for at least the preset number of days in the time slot are the same, the same program contents are supplemented to the vacant position.
Wherein the preset number of days is less than the total number of days before and after the preset number of days. For example, the number of days before and after may be two days before and after, and the preset number of days may be two days. Specifically, if there are more than two days when the program content of the channel in the time slot is the same, it is presumed that the same series or series is played in the time slot every day, the same program content may be supplemented to the vacant position.
In an exemplary embodiment, before the step 330, the method for processing the announcement information of the program provided by the present invention may further include the steps of:
and determining whether the current/subsequent program information is updated according to whether the version number carried by the current/subsequent program information is changed.
It should be noted that, when the front end generates new current/subsequent program information, a version number is configured for the newly generated current/subsequent program information. For example, the version number of the current/subsequent program information generated for the first time is 0001, the version number of the current/subsequent program information generated for the second time is 0002, the version number of the current/subsequent program information generated for the third time is 0004, and so on. The current/subsequent program information issued by the front end each time will carry the version number. Therefore, the intelligent device 110 can know whether the current/subsequent program information is changed or not, that is, whether the current/subsequent program information is updated or not, according to whether the version number carried by the current/subsequent program information issued by the front end is changed or not.
Wherein, the determining whether the current/subsequent program information is updated according to whether the version number carried by the current/subsequent program information changes specifically includes: comparing whether the version number carried by the current/subsequent program information is consistent with the version number of the current/subsequent program information acquired last time; if the program information is inconsistent with the current program information, updating the current/subsequent program information; otherwise, the current/subsequent program information is not updated.
It should be noted that, when the current/subsequent program information is not updated, the version number is not changed, and new current/subsequent program information is generated, and the version number is changed. Therefore, the intelligent device 110 compares the version number of the current/subsequent program information obtained this time with the version number of the current/subsequent program information obtained last time, and compares whether the version numbers of the current/subsequent program information obtained twice are consistent. If the version numbers are consistent, the version numbers are not changed, the information of the current/subsequent programs is not changed twice, and no update exists. On the contrary, if they are not identical, the version number indicating the two times of current/subsequent program information is changed, and there is an update.
Fig. 6 is a flowchart illustrating a method of processing preview information according to another exemplary embodiment. The application scope and execution subject of the processing method of the program announcement information are, for example, the method used in the intelligent device 110 implementing the environment as shown in fig. 1. As shown in fig. 6, the method may include the following steps.
In step 610, when detecting that there is a vacancy in the program announcement information, acquiring a channel and a time period corresponding to the vacancy;
since the schedule information sent by the front end may have individual program information missing, the program schedule information (i.e., the electronic program guide EPG) displayed by the intelligent device 110 is incomplete and has a vacancy. The program announcement information may be the new program announcement information in the above embodiment, and may be the original program announcement information that has been locally cached. The absence refers to that some channels in the program announcement information have no program announcement in some time periods. That is, it is not known what programs will be broadcast on these channels during these time periods, so there is no filling of program content and there is a vacancy. Aiming at the vacancy in the program forecast information, the channel and the time period corresponding to the position of the vacancy can be obtained. That is, it is determined to which time period of which channel the vacancy of the program content is not filled.
In step 630, retrieving program content in the program forecast information for the time slot several days before and after the channel;
wherein, the days before and after can be two days before and after, three days before and after or more. Assuming that the channel corresponding to the vacant position is 'one center', and the corresponding time period is 8: 00-10: 00 of 16 #, the two days before and after 16 # are 14 #, 15 #, 17 # and 18 #. The intelligent device 110 can be two days before and after the channel of 'one center' in the new program announcement information, namely program contents of No. 14, No. 15, No. 17 and No. 18: 00-10: 00. The program content may be a program name.
In step 650, if the program contents of the channel for at least the preset number of days in the time slot are the same, the same program contents are supplemented to the vacant position.
Wherein the preset number of days is less than the total number of days before and after the preset number of days. For example, the number of days before and after may be two days before and after, and the preset number of days may be two days. Specifically, if there are more than two days when the program content of the channel in the time slot is the same, it is presumed that the same series or series is played in the time slot every day, the same program content may be supplemented to the vacant position.
