Detailed ways

The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

First, some terms or concepts used below are explained.

(1) Movie classification information: including movie types (such as dramas, comedies, action movies, etc.), IDs corresponding to movie types, the number of movies included in each movie type, movie ranking information, etc.;

(2) Classified movie information: including detailed information of each movie under each movie type, such as movie name, starring role, plot introduction, link address, etc.;

(3) Movie program information: including movie classification information and movie information of each classification.

Implementation mode one:

This embodiment provides a server, as shown in Figure 1, including:

Acquisition module 11, is used for collecting relevant movie program information from the Internet;

The database operation module 13 is used to establish a database related to the movie program information collected, and is also used to generate a corresponding update file according to the modification operation to the database;

The first receiving module 15 is used to receive the program update request information from the set-top box client;

The first sending module 17 is configured to send corresponding content to the STB client according to the request information.

Fig. 2 (a) and Fig. 2 (b) have shown the working flow of each module of server in a kind of embodiment, wherein, Fig. 2 (a) have described the basic flow of database generation and updating related to the server side, Fig. 2 (b) Describes the updating process of the movie classification information database and the movie information database of each classification.

As shown in Figure 2(a), after the movie information is collected from the Internet, the server creates a movie program information database based on it, and then generates movie classification information databases and movie information databases for each category according to different needs. The maintenance and management of movie program information Updates are all carried out in the movie program information database, including records of changing information, etc. The functions of each module of the server of the present embodiment are embodied by the following steps:

Step S201, the collection module collects relevant movie program information from the Internet;

Step S203, the database operation module establishes a movie program information database on the server side;

Step S205, the database operation module generates a movie classification information database (this embodiment adopts SQLITE database) and each classification movie information database according to different requirements;

The database operation module uses the database to store and maintain the collected movie program information, and generates a movie classification information database and a database of each classification movie information for the set-top box client to download and use. The database can adopt lightweight databases such as SQLITE or Embedded Firebird or SimpleSQL. In this embodiment, a database in the form of small files such as SQLITE is used, that is, an independent movie classification information SQLITE database is generated from movie classification information, and each classification movie information generates its own classification movie information SQLITE database.

Step S207, judging whether there is information change in the movie program information database; if yes, proceed to step S209 to continue, otherwise proceed to step S215 to continue;

Step S209, if there is a change in the movie program information database, record the changed content in the movie program information database, including update information and update time;

Step S211 and step S213 are to regenerate or update the corresponding movie classification information database or each classification movie information database and generate corresponding update files according to the changed content (in this embodiment, SQLITE database and format are adopted as update files of XML files); The specific update process of these two steps is shown in Figure 2(b);

Step S215, establishing a download link for the user to download. The subsequent server will interact with the STB client through its first receiving module and first sending module.

As shown in Figure 2 (b), it is the specific process of steps S211 and S213, including:

Step S251, generating data for the STB client to download;

Step S252, judging whether there is data update in a classified movie information database, if yes, proceed to step S253, otherwise proceed to step S255;

Step S253, generating a new SQLITE database, and compressing each database into a zip package;

Step S254, generate the update file of SQLITE database (embodiment adopts XML format);

Step S255, judging whether it is the last classification; if yes, go to step S256 to continue, otherwise go to step S252 to judge again;

Step S256, judge whether there is at least one category that has updated data; if not, end the judgment on the update situation, if yes, go to step S257;

Step S257, generating a new movie classification information SQLITE database.

For the movie classification information database, it has common database operation functions such as adding, modifying, deleting, etc., and also has the prohibition function that prohibits users from accessing and using certain movies; the modification operation of the movie classification information database records its detailed information in a predetermined format Change data and change time data, the predetermined format includes but not limited to log table. For each classified movie information database, it also has common database operation functions such as adding, modifying, deleting, etc., and also has a disable function that prohibits users from accessing and using certain movies; changes to the classified movie information database are recorded in a predetermined format Its detailed change data and change time data, the predetermined format includes but not limited to log table.

If there is no change operation in a classified movie information database, the classified movie information database will not be regenerated; otherwise, the classified movie information database will be regenerated; if there is no change operation in all classified movie information databases, the movie classification will not be regenerated information database, otherwise, the movie classification information database must be regenerated. Each database is finally compressed into a package, such as compressed into a zip file.

In the database operation module, after the classified movie information database is maintained (that is, a change operation occurs), an update file of each classified movie information database will be generated according to the modified data and the modified time data, describing each category within a predetermined time (for example, within 1 day) Updates to movie information. For example, if a piece of movie information is added to a certain classified movie information database today, an update file for today is generated, which records the change operation of the classified movie information. Different classified movie information databases have their own update files, and a classified movie information database has a predetermined number of different update files; for example, a certain classified movie information database has 30 different update files, and the first update file records the previous The update situation of this classified movie information data in one day, the update situation of this classified movie information since the Nth update file records the previous N days, the update situation of this classified movie information since the 30th update file record since the previous 30 days; Set-top box clients with different levels of new and old movie program information can be downloaded and used, that is to say, update files can be selected for the corresponding number of days according to the number of days that the set-top box client has not been updated, which avoids blind downloading and greatly reduces the amount of data downloads . In the embodiment, the update file adopts XML file format.

In the embodiment, the server generates the database by downloading information through HTTP (HyperText Transfer Protocol, hypertext transfer protocol), and the first receiving module and the first sending module of the server communicate with the set-top box client through the HTTP protocol, therefore, the compression of the embodiment The packaged database files (such as zip files) or update files contain HTTP header information, which is used to record some necessary information such as update time and file size of each database file or update file. It can be understood that if the communication between the server and the set-top box client adopts other protocols, the compressed database file (such as a zip file) or the update file contains header information corresponding to other protocols. The specific processes of downloading, establishing/generating a database, and establishing a download link involved in the embodiments can be implemented by common technical means known to those skilled in the art, and the embodiments are not limited thereto.

The server of this embodiment collects movie program information on the server side, and stores updated data on the server side for downloading when needed by the set-top box client side, reducing the number of local data update operations and the consumption of related system resources as much as possible. .

Implementation mode two:

This embodiment provides a set-top box client, as shown in Figure 3, including:

The second sending module 21 is configured to send request information to the server;

The second receiving module 23 is configured to receive information fed back by the server according to the request information;

The update module 29 is configured to determine content to update the local movie program information of the STB client according to the received feedback information.

Further, the update module includes a local library update unit and an update time storage unit, and/or a time judging unit, and/or a quantity judging unit.

The modules of the set-top box client in this embodiment are described below through several embodiments and with reference to FIGS. 4-6 .

Example 1: Manually force update data.

For the manual forced data update method, the functions of each module of the set-top box client are embodied through the process shown in FIG. 4 . As shown in Figure 4, the user performs data mandatory update through the manual mandatory update function of the set-top box client. At this time, the second sending module sends the request information of downloading the movie classification information database and/or the classification movie information database to the server, and the second receiving module Receiving the movie classification information database and/or classification movie information database fed back by the server, the update module directly replaces the possible original database of the set-top box client with the relevant database received from the second receiving module (if the set-top box client does not originally have relevant database, the update module directly provides the related database received by the second receiving module to the set-top box client for use). Specifically, the update module includes a local library update unit and an update time storage unit, and the local library update unit provides the movie classification information database and/or the classification movie information database obtained after downloading to the set-top box client (i.e. replaces the local one of the set-top box client). Movie program information), if downloading is the compressed package (as zip package) of corresponding database, then provide use after it is decompressed, meanwhile, the update time preservation unit is used to store the update of corresponding database file at the set-top box client time. Here, the realization of the manual forced update function of the set-top box client can be realized by common means, for example, a button such as "update" can be set on the set-top box client for the user to use, or a menu such as The mode is input and selected by the user through the remote control, mouse or keyboard. The function of manual forced update is to take into account the unpredictable update needs that users may have, such as the database is damaged and needs to be updated when the power is off, or the user requests for updates from time to time, etc. For this kind of manual forced update, the set-top box client cannot predict the user For specific information needs, therefore, the update module directly replaces the possibly original database file of the set-top box client with the newly downloaded database file. Of course, if the download fails, the client can prompt the user that the update failed.

Example 2: Automatically update data.

The data updating process in Embodiment 2 is similar to the manual forced data updating process, the difference is that the set-top box client self-checks and automatically updates. As shown in Figure 5, it includes the following steps:

Step S501, power-on self-test;

Step S503, when the set-top box client is started, it automatically detects whether there is a database related to the movie program information in its local area, if there is a relevant database, then go to step S505 to continue, if it does not exist, then go to step S506 to continue;

There are many reasons why the set-top box client does not have relevant database files locally. For example, the set-top box client has not been initialized or the database file is lost due to various factors, so that there is no relevant database file locally.

Both step S505 and step S506 are to download the database related to the movie program information; that is, the second sending module sends the request information for downloading the movie classification information database to the server, and the second receiving module receives the movie classification information database and/or classification fed back by the server. Movie information database. For step S505, the local library update unit of the update module will directly provide the set-top box client with the downloaded movie classification information database and/or classified movie information database, and for step S506, the local library update unit of the update module will download The database directly replaces the original database file of the set-top box client. If the download is a corresponding database compression package (such as a zip package), it will be used after decompression. At the same time, the update time storage unit of the update module is stored in the set-top box client. The update time of the corresponding database file.

Embodiment 3: Automatically update data.

As shown in Figure 6 (a), the flow process of the set-top box client of this embodiment automatically updating data includes as follows:

Step S601 and step S603 are respectively the same as step S501 and step S503 of embodiment 2, and will not be repeated here;

When the result of the self-check is that there is no database related to the movie program information locally in the set-top box, go to step S611 and continue; when the self-check finds that there is a database related to the movie program information locally on the set-top box client, go to step S621 and continue.

Step S611 is the same as step S505 of Embodiment 2, and will not be repeated here;

Step S621, obtaining the header information of the required update file;

Now the second sending module resends the request to the server, and the request information is the HTTP header information of the update file that requests to download (it should be understood that if the communication between the server and the set-top box client adopts other protocols, then the request is related to other protocols Corresponding header information), the second receiving module receives the HTTP header information of the updated file fed back by the server;

Step S623, judging whether to update according to the update time;

The time judgment unit of the update module compares the update time stored in the update time storage unit with the update time in the HTTP header information of the update file acquired by the second receiving module. If the two are the same, then do not perform any subsequent operations to avoid repeated downloads and data updates; if the two are different, go to step S625;

In step S625, it is known from the aforementioned judgment that the update time is inconsistent, indicating that there is new movie program information on the server side that has been updated, then the second sending module re-sends request information to the server, and the request information is an update file requesting to be updated.

Embodiment 4: Automatically update data.

As shown in Fig. 6 (b), the present embodiment is an improvement of embodiment 3, step S601', step S603', step S611', step S621', step S623' in the figure are respectively the same as step S601 of embodiment 3 , step S603, step S611, step S621, and step S623 are the same, and will not be repeated here;

When the judgment in step S623 is known, if the update time stored in the update time storage unit is different from the update time in the HTTP header information obtained by the second receiving module, then go to step S625' to continue, and if they are the same, then end the update process;

Step S625', judging the amount of data to be updated;

The quantity judging unit of the update module judges whether the amount of data to be updated (i.e. the size of the update file) contained in the HTTP header information received by the second receiving module exceeds a predetermined amount of data, and the amount of data to be updated is the amount of data that needs to be updated this time. The amount of data, the predetermined amount of data is a preset file size, such as 20KB. If the amount of data exceeds the predetermined amount of data, then go to step S626', and determine that the classified movie information database needs to be downloaded to replace the original local database; Download the update file, and update the local database according to the update file.

In step S626', the second sending module resends request information to the server, requesting to download the classified movie information database that needs to be updated. The second receiving module receives the database file fed back by the server. The local library update unit of the update module provides the classified movie information database obtained by downloading to the set-top box client for use. If it is a corresponding database compression package (such as a zip package), it will be decompressed and then provided. At the same time, the update time is saved. The unit saves the update time of the corresponding database file on the set-top box client;

Step S627', similarly, the second sending module sends a request message requesting to download the update file to the server, and after receiving the update file fed back by the server, the local library update unit analyzes the data update information in the update file obtained, and according to The parsing result performs an update operation on the classified movie information database existing locally. It can be understood that the set-top box client (local library update unit) has a file parsing function to parse and update files; and there may be multiple classified movie information databases involved. The automatic update in this embodiment can not only avoid frequent data downloads, but also avoid excessive local database update operations, and take into account the problem of mutual balance between network traffic and set-top box clients.

The specific processes of downloading, decompression, replacing the downloaded movie program information with the local movie program information, time judgment, data volume judgment, parsing and updating files, etc. involved in the above examples can use common technical means well known to those skilled in the art implementation, which is not limited by the embodiment.

In order not to affect the current use of the user, the user use data directory and the data update directory are designed when implementing the local library update unit. Among them, the user use data directory is used to store the movie program information directly used by the user, and the data update directory is used for Update and store the movie program information obtained according to the database or update file received by the second receiving module.

To sum up the above embodiments, taking the database file related to the movie program information as a compressed package as an example, the functions of each module of the set-top box client in this embodiment can be embodied by the data update process shown in Figure 7 (for ease of understanding, Figure 7 shows The process of forced update of data is not included in the flow shown, but it should be understood that the set-top box client in the embodiment has the function of forced update).

As shown in FIG. 7 , most of the processes included in the flow are similar to those of the foregoing embodiment 4, such as step S701 to step S721 and step S725 , etc., which will not be repeated here.

During specific implementation, each set-top box client stores two sets of complete data, one set is stored in the user use data directory, and the other set is stored in the data update directory. The user uses the data directory for the user, and the data update directory is used for updating. Both directories use two directories to store complete data. It should be understood that the two directories are relative and replaced in turn, that is, after each new data is updated, Switch the directory that the user uses to store the updated data, and the original directory is refreshed as the data update directory.

During actual processing, decompress the compressed package of the classified movie information database to the data update directory (set as directory B), and then copy its content to the user data directory (set as directory A). When copying, you can add the database file name to Add a suffix such as ".bak" for the last update of directory A. After the copy is finished, switch the directory so that the user can directly use directory B (at this time, directory B is the user's data directory), and then update directory A (at this time, directory A is the data update directory), and the operation on directory A can be such as deleting For disabled database files, replace the old database with all files with suffixes removed.

The set-top box client of this embodiment has a mandatory update function and an automatic update function. In the automatic update function, although multiple judgments may be involved, the amount of data sent and received (that is, HTTP header information) involved in these judgments is relatively small, so The speed is very fast, and at the same time, the downloaded content is determined by judging the data volume of the content to be updated, which can minimize the data download volume of the movie program information, and shorten the update time of the movie program information, so that users can get the latest information as soon as possible Movie program information, ultimately improving the user experience.

Implementation mode three:

This embodiment provides a data update system based on a set-top box, as shown in FIG. 8 , including: a server 1 and at least one set-top box client 2, wherein,

Figure 9 shows an interaction between the set-top box client and the server. At this time, the set-top box client sends a download request to the server after detecting that there is no relevant database in the local area through self-checking or manual forced update by the user. The server side receives the related database request and feeds back the database to the set-top box client side according to the related request.

Figure 10 describes another interaction between the set-top box client and the server. At this time, after the set-top box client self-checks and finds that there is a database file locally, it sends a header to the server to obtain the required update file (such as an XML file). The request for information, the server accepts and feeds back the header information of the file to be updated according to the request. Here, because each update of the database will generate a corresponding update file, the header information of the file already contains the required database status information, so it is not necessary to obtain the header information of the database file; of course, those skilled in the art can also take Get the header information of the required database file for related processing. In FIG. 10 , the update time of the local database of the set-top box client is consistent with the update time of the corresponding database of the server.

Fig. 11 has described another situation of the interaction between the set-top box client and the server. At this time, the update time of the local database of the set-top box client is inconsistent with the update time of the corresponding database of the server. Then, the set-top box client will judge the update file again. size, and send a corresponding request according to the judgment result (if the size of the update file to be obtained is equal to or greater than the predetermined amount of data, then send a request to obtain a download request for the database, otherwise send a request to obtain a download request for the update file). The specific processes involved in FIG. 9-FIG. 11 are the same or similar to the corresponding processes involved in the first embodiment and the second embodiment, and will not be repeated here.
