Description
Technical Field
The present application relates to the field of live broadcasting, and more particularly, to a method of updating a program guide and an apparatus thereof.
Background
In a live Broadcasting operation scenario such as Internet Protocol Television (IPTV), Digital broadcast Television (DVB), etc., a network operator needs to maintain a program list in a live Broadcasting channel. Generally, the television programs are written in an Extensible Markup Language (XML) file format, and the TV program writing specification based on the XML file format is abbreviated as the XMLTV specification.
In the xml tv specification, a program list in a certain channel of a Content Provider (CP) can be synchronously updated to a Content Management System (CMS) in a batch manner. However, there is no explicit in the XMLTV specification as to what type of operation, such as addition, modification or deletion, the change of the program in the program guide belongs to. The CMS needs to compare each newly introduced program of the CP with existing programs in a Database (Database) field by field, and analyze whether there is a difference between the newly introduced program and the existing programs.
However, in an actual operation scenario, many programs in the program list imported by the CP are repeated, for example, the program with the number 3/month 1 in 2017 is the program with the number 3/month 2 in 2017 to the number 3/month 15 in 2017, the program with the number 3/month 2 in 2017 is the program with the number 3/month 3 in 2017 to the number 16 in 2017, actually, the programs with the numbers 3/month 3 in 2017 to the number 3/month 15 in 2017 are mostly repeated, only individual programs are modified, and the program with the number 3/month 16 in 2017 is newly increased.
When the number of channels and programs is large, for example, 1000 channels, one program every 20 minutes, and a program list of two weeks is synchronized at a time, there are 100 ten thousand programs. If the newly introduced program list is compared with the programs in the existing program list in the database one by one to judge whether the programs are different, the time for CMS processing is very long, and the time for CP to wait for the response of the completion of the introduction is also long, so that the latest program list record watched by the terminal user is delayed and the user experience is influenced.
Therefore, a method for updating a program guide is needed to improve the efficiency of updating the program guide.

Detailed Description
The technical solution in the present application will be described below with reference to the accompanying drawings.
FIG. 1 is a schematic block diagram of an application scenario of one embodiment of the present application. As shown in fig. 1, the CP is used to provide live program, that is, the CP is used to import the program to the CMS; a File transfer protocol Server (FTP Server) for placing the program files issued by the content provider; the CMS is used for managing the presentation of the program list in the video service terminal equipment and organizing the program list content for the terminal equipment; database is used to save program listings records.
The following briefly describes a process in which the CMS acquires an XMLTV file describing a certain program from the CP through the FTP Server, and stores the XMLTV file in the database after parsing the XMLTV file. The specific process is as follows: after the CP finishes editing the XMLTV file, uploading the XMLTV file to an FTP server; the CP transmits a Simple Object Access Protocol (SOAP) request message for issuing an XMLTV file to the CMS, the SOAP request message including a path of the XMLTV file on the FTP server; after receiving the SOAP message request, the CMS returns a response; the CMS downloads the XMLTV file according to the path of the XMLTV on the FTP server; the CMS parses the XMLTV file; if the XMLTV records have reference poster pictures, the CMS needs to download the pictures from the FTP server; the CMS updates the program information in the CMS database according to the analyzed program record; the CMS sends the processing result of the XMLTV file to the CP; and after receiving the SOAP message initiated by the CMS, the CP returns a response.
The program list represented by the XMLTV file shown below is composed of 2 channels (channels) and a plurality of program (program) nodes, each of which is composed of a plurality of attribute and child element nodes.
In the existing XMLTV specification, after downloading the XMLTV file from an FTP server, a CMS analyzes the XMLTV file; the CMS queries all programs under a channel from a database; CMS compares the imported programs of the XMLTV file with the differences of each program originally recorded in the database item by item; if the broadcast time of a program changes, the original record needs to be deleted first, and then a new program list record needs to be created. It should be understood that the playout time includes a start time and an end time.
Since the programs have no unique identification field, it can only be determined whether the programs are the same program by three elements, i.e., channel, start time, and end time. If the broadcasting time of a certain program is changed, the program in the database can only be deleted first, and then the program imported by the CP is created in the database.
In the above method, comparing the newly introduced program list with the existing program list in the database one by one to see whether there is a difference between the programs in the existing program list, the CMS processing time is very long, and the CP waits for the response of the completion of the introduction, so that the latest program list record viewed by the terminal user is delayed, which affects the user experience.
Therefore, the embodiment of the application provides a method for updating a program list, which can improve the updating efficiency of the program list.
Fig. 2 shows a schematic flow chart of a method of an embodiment of the present application. As shown in fig. 2, the executing subject of the method may be a CMS system, and the method 200 includes:
Specifically, in step 210, for example, the summary generation process of the target program is as follows: the CMS concatenates all fields in the target program node in the XMLTV into a character string according to a preset order, for example, in JAVA, the target program node may be parsed into an object, and the attribute of the object may be converted into a character string according to a preset order and output.
Using a summarization algorithm (e.g., SHA-256, MD5) to generate a summary of the target program, where the summarization result may be a 2-ary byte array, and optionally, the byte array may be converted into 16-ary characters, for example: "67b55abd13610c8dc02ac73b206b5b8ad579c2cff6f061f2f9e06f2cca7c2d 03".
It should be understood that the preset sequence refers to a splicing sequence of each element field in the program node, and the preset sequence is not limited in this application, and for example, the preset sequence is to splice the following fields in sequence: a broadcast time field, an actor field, a program title field.
In step 210, the target program may be any one of the programs imported by the CP, the target program is a program in the target channel, the programs already existing in the target channel may be stored in the database, and the CMS also generates a corresponding summary of each program in the programs already existing in the target channel and stores each program in the target channel and its summary in the database.
It should be understood that all information fields identifying a target program may be transmitted in a manner other than in the XMLTV specification, such as text transmission by separating the fields of the program by separators (e.g., |), which are not limited in this application.
Therefore, the method provided by the embodiment of the application determines whether to update the program in the target channel by comparing the abstract of the target program with the abstract of each program in the target channel, which is beneficial to improving the efficiency of updating the program list and reducing the occupation of the system resources due to the updating of the program list.
Optionally, as an embodiment of the present application, the determining whether to update the program in the target channel according to a comparison result between the summary of the target program and the summary of each program in the target channel includes: when the summary of the target program is the same as the summary of an existing program in the target program channel, the program in the target program channel is not updated.
The abstract of each program is a uniquely determined character string generated according to all fields of the program and a preset rule, so that when the abstract of a target program is the same as the abstract of a program existing in a target channel, the target program is proved to be unchanged.
Therefore, the method provided by the embodiment of the application does not need to compare each element field in the program node one by one, and can determine whether the target program needs to be used for updating the program in the target program channel only by comparing whether the existing program abstract and the target program abstract are the same or not.
Optionally, as an embodiment of the present application, the determining whether to update the program in the target channel according to a comparison result between the summary of the target program and the summary of each program in the target channel includes: and when the abstract of the target program is different from the abstract of each program in the target program channel, updating the programs in the target program channel.
Because the abstract of each program is a uniquely determined character string generated according to all information fields of the program and preset rules, when the abstract of the target program is different from the abstract of one program already existing in the target channel, the target program is proved not to be stored in the database or one or more elements included in the target program node are changed.
Optionally, as an embodiment of the present application, the updating the program in the target program channel includes: and when the broadcasting time interval of the target program has an overlapping part with the broadcasting time interval of the failed program existing in the target channel, replacing the failed program in the target channel with the target program.
Specifically, if the broadcast time of the target program changes, the existing records in the time slot corresponding to the target program need to be deleted, and a record of the target program is created, wherein the record of the target program comprises the information field of the target program.
Optionally, as an embodiment of the present application, before the comparing the summary of the target program with the summary of each program already existing in the target channel, the method further includes: and receiving an information field which is sent by a content provider CP and used for representing the target program, and generating the abstract of the target program according to all the information fields representing the target program and the preset rule.
That is, the CMS needs to receive the information field of the target program sent by the CP, and generate the digest of the target program according to the information field of the target program and the preset rule.
The method of the embodiments of the present application is described below with reference to specific examples. FIG. 3 is a schematic flow chart diagram of a method of one embodiment of the present application. As shown in fig. 3, the method includes:
in step 301, after the CMS downloads the XMLTV file from the FTP server, the CMS parses the XMLTV file.
Step 302, the CMS queries the database for existing summaries of the program listings. It should be understood that, since the byte number of the summary field is much smaller than that of all the information fields of the program, if the memory allows, the summary of the program can be saved in the memory, and the query speed is increased.
Step 303, the CMS calculates the summary of each program in the XMLTV file newly imported this time, and the process of calculating the summary of each program needs to be consistent.
Step 304, comparing the abstract of each program in the newly imported XMLTV file with the abstract of the existing program to determine whether the abstract is the same.
Step 305, if the abstracts are the same, it means that the imported program is repeated and the same, and does not need to be updated. Depending on the operating scenario, more than 80% of the programs can be filtered out at this step.
If the abstracts are different, step 306, a step of comparing the difference between the newly introduced program and the existing program is needed.
Step 307, if the broadcasting time of the program is changed, the existing program record corresponding to the broadcasting time of the program needs to be deleted first, and then a new program record is created.
Specifically, the broadcast time of the program includes a start time and an end time, and the change of the broadcast time of the program means: the start time and the end time of the original program in the database are different from the start time and the end time of the new program in the newly imported XMLTV file. Since the program has no unique identification field, it needs to determine whether it is the same program by channel, start time, end time, and three elements. Specifically, if the broadcast time of a program changes, the existing records in the time slot corresponding to the program need to be deleted, and a record of a newly introduced program needs to be created.
Step 308, if the broadcast time of the program is not changed, other field information of the program may be updated according to the channel, the start time, and the end time, where the other field information includes a program name field, a program description field, a date of production field, and the like, which is not limited in this application.
It should be understood that since the program recording in one channel is plural, steps 4 to 8 need to be performed cyclically.
The CMS may determine whether there is a change in the program by calculating an abstract of the program, storing the abstract in the CMS system, and comparing the abstract with an abstract of a newly introduced program, thereby increasing the processing speed.
Optionally, as an embodiment of the present application, before the comparing the summary of the target program with the summary of each program already existing in the target channel, the method further includes: and receiving a complete information field which is sent by the CP and used for representing the target program, wherein the complete information field of the target program comprises the identification of the target program and the abstract of the target program generated by all information fields of the target program according to the preset rule.
In the XMLTV specification, an identification (id) field and a digest (digest) field are extended in attributes of program. The id field needs to ensure uniqueness, and the id can uniquely identify whether the programs are the same, so that the processing of judging whether the programs are the same through the combination of three elements, namely a channel, the program starting time and the program ending time is simplified. The digest field of a certain program is calculated by the CP according to all the information fields of the program, and the generation algorithm of the digest is not limited in the present application.
Therefore, in the embodiment of the application, by extending the program ID and the Digest field in the attribute of the program, the newly introduced repeated program can be quickly eliminated, and the speed of issuing the program by the CMS is increased.
Optionally, as another embodiment of the present application, the determining whether to update the program in the target channel according to a comparison result between the summary of the target program and the summary of each program in the target channel includes: determining whether the target program is a program already existing in the target channel according to the identifier of the target program; if the target program is not the program already existing in the target channel, saving an information field of the target program; and if the target program is the program already existing in the target channel, comparing the abstract of the target program with the abstract of the program already existing in the target channel.
Specifically, if the program is modified, the newly introduced program is the same as the already existing program id, that is, the newly introduced program and some already existing program are the same program. Therefore, the CMS may further compare the digest to determine whether the program has been modified. If the digest values are different, the parameter value of the program is changed, otherwise, the parameter value of the program is not changed.
If the id of the newly introduced program is different from the id of any existing program, it indicates that the CP introduces the new program in the XMLTV file, and the CMS directly creates and saves the new program.
The program list represented by the XMLTV file shown below is composed of 2 channels (channels) and a plurality of program (program) nodes, each of which is composed of a plurality of attribute and child element nodes. The program node includes an id field, for example, id ═ 287547", and a summary field, for example, a summary field
The method of the embodiments of the present application is described below with reference to specific examples. Fig. 4 is a schematic flow chart of a method of one embodiment of the present application, as shown in fig. 4, the method comprising:
in step 401, after the CMS downloads the XMLTV file from the FTP server, the CMS parses the XMLTV file.
Step 402, the CMS queries the existing program record in the database according to the id of the newly imported program in the XMLTV file. Optionally, since the number of bytes of the program id field is small, if the memory allows, the id record can be saved in the memory, so as to speed up the query.
Step 403, if the program id exists, comparing the digest of the newly introduced program with the digest of the original program. If id does not exist, jump directly to step 407.
In step 404, if the existing program digests of the newly introduced program digest are the same, this indicates that the introduced program record is repeatedly the same and does not need to be updated. Depending on the operating scenario, more than 80% of the program listings can be filtered out at this step.
In step 405, if the existing program summaries of the newly introduced program summary are not the same, the information of the program may be updated to the database according to the program id.
Step 406, if the id does not exist, it indicates that the imported program list is a new program list record, and the new program list record is directly created and stored in the database.
It should be understood that if the program imported by the CP is recorded in a plurality of pieces, steps 403 to 706 need to be performed in a loop.

It is understood that the device 500 is capable of performing the various steps performed by the CMS in the methods of fig. 2-4, and will not be described in detail herein to avoid repetition. The network device 500 includes:
