Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the 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.
The term "and/or" in the embodiment of the present invention is only one kind of association relationship describing an associated object, and indicates that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" in the embodiment of the present invention generally indicates that the preceding and following related objects are in an "or" relationship.
For the convenience of clearly describing the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, the words "first", "second", and the like are used to distinguish the same items or similar items with basically the same functions and actions, and those skilled in the art can understand that the words "first", "second", and the like do not limit the quantity and execution order.
Referring to the block diagram of fig. 1, the operation principle of the embodiment of the present invention is that a processing device of authorization management information (a set-top box or a combination of the set-top box and a display) receives authorization management information sent by a front end of a conditional access system, classifies and filters the authorization management information, discards invalid data, and pushes valid authorization management information (hereinafter, referred to as valid information) to a user, so that the user can view the valid information through a digital television. Specifically, the front end of the receiving condition receiving system may send the authorization management information to the set-top box, and the set-top box sends the authorization management information to the display after processing, so that the user can view the authorization management information through the display. The set-top box and the display can form an integrated machine or can be independently arranged.
In addition, if the size of the storage resource of the embodiment is consistent with that of the storage resource in the prior art, the embodiment of the invention does not cause data blocking due to untimely data processing, and on the contrary, the embodiment of the invention can store more effective information, thereby reducing the loss of the effective information caused by data blocking. Meanwhile, relatively speaking, in the same time, the processing device for authorizing the management information receives more emm data, and the data receiving rate is improved.
For example, the data structures of the authorization management information may include the following two types, as shown in table 1 and table 2, but other data structures may also be available, which are not listed here. It should be noted that the fields in the two tables are only partial fields of the real authorization management information.
Table 1: structure 1 of authorization management information
Table 2: structure 2 of authorization management information
In the following, a method for processing authorization management information provided by an embodiment of the present invention will be described in detail in conjunction with the above two types of authorization management information.
Example one
The embodiment of the invention provides a processing method of authorization management information, wherein an execution subject of the method is a processing device of the authorization management information, and the device can be a set top box shown in figure 1, also can be an all-in-one machine of the set top box and a display, and also can be some hardware and/or software modules in the set top box. As shown in fig. 2, the method comprises the steps of:
s101, receiving authorization management information sent by the front end of the conditional access system.
The conditional Access system may be a CAS (conditional Access system), and in the embodiment of the present invention, the conditional Access system is preferably a B-CAS.
For convenience of subsequent description, the authorization management information received in this step is recorded as: emm _ T.
S102, determining the information attribute of the authorization management information (emm _ T).
The step may specifically include: and determining the information attribute of the emm _ T according to the field in the emm _ T, wherein the information attribute comprises shared (common) information or personal (individual) information. Those skilled in the art will appreciate that this field is a field that determines whether emm _ T is shared information or personal information.
The following are exemplified: according to two fields of table _ id and table _ id _ extension in the authorization management information, classifying the authorization management information, namely determining the type of each authorization management information. Specifically, if emm _ T has the data structure shown in table 1, and at this time, table _ id in emm _ T is 0x85 and table _ id _ extension is one of 0x0001 to 0xFFFF (that is, table _ id _ extension is not 0x0000), emm _ T is shared information. If emm _ T has the data structure of table 2, and at this time, table _ id of emm _ T is 0x85 and table _ id _ extension is 0x0000, emm _ T is personal information.
S103, determining whether the emm _ T is valid according to the information attribute of the authorization management information (emm _ T).
The authorization management information can be set as valid information and the authorization management information can be set as invalid information according to actual requirements, so long as the authorization management information required by the user can be pushed to the user, and redundancy in the process can be avoided.
Wherein, if emm _ T is shared information, the step specifically includes: it is determined whether the emm _ T is duplicated with the historical entitlement management information. The historical authorization management information is authorization management information received in a time period before emm _ T is received, and one of the historical authorization management information may be the same as emm _ T, for example, the historical authorization management information which is the same as emm _ T may be marked as emm _0, and at this time, it is considered that repeated historical authorization management information exists.
For example: the authorization management information processing device may be provided with a database for storing the historical authorization management information or a field used for determining whether to repeat the historical authorization management information. Exemplary fields for determining whether to repeat include: table _ ID _ extension, version _ number, group _ ID.
At this time, the step may be comparing a field used for determining whether to repeat in the received emm _ T with a field used for determining whether to repeat in the historical authorization management information in the database, and if table _ ID _ extension, version _ number, and group _ ID of the emm _ T and one piece of historical authorization management information (e.g., emm _0) in the database are the same, determining that the emm _ T and the historical authorization management information are repeated, and at this time, the emm _ T is invalid; otherwise, there is no repetition, and the emm _ T is valid.
In addition, if emm _ T is personal information, this step may include: it is determined whether the emm _ T contains a local card number. The local card number refers to a card number of a smart card inserted into the authorization management information processing apparatus in this embodiment.
For example, if emm _ T is personal information, a local card _ ID (smart card number) is acquired, and the local card _ ID is compared with a card _ ID in emm _ T, if the card _ ID in emm _ T is consistent with the card _ ID of the emm _ T, the emm _ T is valid, otherwise, the emm _ T is invalid.
And S104, if the emm _ T is invalid, discarding the emm _ T.
The implication of discarding invalid entitlement management information is: the invalid entitlement management messages are not subsequently processed. Further, the invalid authorization management information is not saved, and at this time, the invalid authorization management information is not used as the historical authorization management information in the process of subsequently receiving other authorization management information again.
It should be noted that, the above steps S101 to S104 may be performed by some hardware and/or software modules in the set-top box, for example, may be performed by the data obtaining module.
And S105, if the emm _ T is effective, performing subsequent processing.
This step may be a processing method in the prior art, or may be a processing method in the second embodiment later in this application, so as to push the emm _ T to the user.
The embodiment of the invention provides a processing method of authorization management information, wherein a processing device of the authorization management information receives the authorization management information sent by a front end of a conditional access system, classifies and filters the authorization management information according to the information attribute of the authorization management information, and discards invalid data. Compared with the prior art, the embodiment of the invention solves the problems that a large amount of frequent emm data occupies large storage resources, and the emm data is not processed timely, so that the jam and the data loss are easily caused, thereby saving the storage resources (such as cache) and improving the data processing rate and the data receiving rate.
Example two
The method for performing subsequent processing on the effective emm _ T obtained in step S105 of the above embodiment includes the following steps, as shown in fig. 3:
s201, if the emm _ T is valid information, determining the type of the information content in the emm _ T.
The step may specifically include: the type of the information content in the emm _ T is determined according to the field in the emm _ T, wherein the type of the information content comprises mail (mail) or notification (message). For example, if the valid emm _ T is personal information, whether the information content in the emm _ T is a mail or a notification is distinguished according to the Message control in the emm _ T. If the valid emm _ T is the shared information, first, it is required to compare a format _ version field in the shared information with an extra _ message _ format _ version field in an information list (when the emm _ T is the personal information, the information list collects the extra _ message _ format _ version field therein, which is used to indicate whether the subsequently received emm _ T shared information is the local information) field, so as to distinguish whether the received valid authorization management information is the data that the local computer needs to receive currently. If the data is the data which needs to be received by the current local machine, distinguishing whether the data is the mail or the notification according to the Message control, and otherwise, discarding the data. It should be noted that, when the valid authorization management information is shared information, this step performs filtering of the emm information once again, discards redundant emm information, further saves cache resources, and improves the data processing rate of the authorization management information processing apparatus.
It should be noted that, the above step S201 may be performed by some hardware and/or software module in the set-top box, for example, may be performed by a data classification module in the set-top box.
S202, analyzing and storing the information content in the emm _ T from the emm _ T according to the information attribute of the emm _ T and the type of the information content in the emm _ T.
In the first case: referring to fig. 4, the information content in emm _ T is a mail, and the specific process is as follows.
(1) If the emm _ T is personal information and the information content is a mail (denoted as emm _ T _ email), the method specifically comprises the following steps: and detecting whether the emm _ T _ incoming is encrypted, if so, analyzing the decrypted emm _ T _ incoming and storing the information content of the emm _ T _ incoming, otherwise, directly analyzing the emm _ T _ incoming and storing the information content of the emm _ T _ incoming. Further, in this process, the processing device of the authorization management information may collect the information of the extra _ message _ format _ version field in the emm _ T _ email and store the information in the information list, which may be stored in a form without the information list as long as there is a predetermined storage space.
For example, for the emm _ T _ incoming, whether the emm _ T _ incoming is encrypted information may be detected according to a Protocol number in the emm _ T _ incoming. If the emm _ T _ email is encrypted, the emm _ T _ email is sent to the smart card for decryption, and the decrypted emm _ T _ email returned by the smart card is received and stored; if emm _ T _ email is not encrypted, directly storing. And collecting the information of the extra _ message _ format _ version field in the emm _ T _ email and storing the information into the information list.
Wherein, if the Protocol number in the emm _ T _ incoming is 0xff, it indicates that the emm _ T _ incoming is not encrypted, otherwise, the emm _ T _ incoming is encrypted.
(2) If the emm _ T is shared information and the information content is mail (denoted as emm _ T _ mail), the method specifically comprises the following steps: and detecting whether the emm _ T _ mail is authorization management information for the machine, if so, analyzing the emm _ T _ mail and storing the information content of the emm _ T _ mail, and otherwise, discarding.
For example, for the emm _ T _ mail, first, the format _ version in the emm _ T _ mail is acquired, and whether the same information as the format _ version exists is searched from the information list for storing the extra _ message _ format _ version information. If yes, the mail is mail data corresponding to the local machine and is stored; otherwise, the mail is discarded. In the step, the emm information is filtered again, redundant emm information is discarded, storage resources can be further saved, and the data processing rate of the processing device for the authorization management information is improved.
Further, no matter emm _ T is the above-mentioned emm _ T _ email or emm _ T _ email, parsing and storing the information content of emm _ T may include: storing the emm _ T into a first storage module, when the number of the authorization management information in the first storage module reaches a preset number, packaging the authorization management information with the preset number, storing the authorization management information content obtained after packaging into a second storage module, and deleting the authorization management information with the preset number in the first storage module from the first storage module.
It should be noted that, in this embodiment, the first storage module is a storage space in the memory, and may be a data block, and the emm _ T may be stored in the storage space in an information list manner. The second storage module is a storage chip, so that a display can read the information content (e-mail) of the emm _ T from the storage chip so as to display the emm _ T on the display; examples may be e2prom, flash, ram, etc.
The process of packaging the preset number of authorization management information may include: and extracting respective information content from the preset number of pieces of authorization management information so as to store the extracted information content into the second storage module.
Further, the process of performing the packaging processing on the preset number of authorization management information may further include: redundant authorization management information with the same message _ ID and group _ ID is filtered from the preset number of authorization management information, the receiving time of the authorization management information is compared with the effective time period limit _ date of the mail, and if the receiving time is not in the effective time period, the authorization management information does not need to be sent to a second storage module; that is, if the message _ ID and the group _ ID of the plurality of pieces of entitlement management information are the same and the reception times thereof are within the valid period, only one of the pieces of entitlement management information may be retained. And then, extracting the information content and the like on the authorization management information retained after filtering so as to store the extracted information content into the second storage module. The filtering of the emm information is carried out again in the step, redundant emm information is discarded, storage resources can be further saved, and the data processing rate of the processing device for the authorization management information is improved.
Furthermore, after the information content of the authorization management information is stored in the second storage module, the processing device of the authorization management information can also notify the display device of the arrival of a new mail in an event mode, that is, the display device displays the identification of the received new mail to prompt the user to receive the new mail. The display device can read and display the mail corresponding to the new mail identification from the second storage module according to the reading instruction of the user, so that the user can read the mail. The mail information may be stored in the second storage module until the display device notifies the processing device of the authorization management information after receiving a deletion instruction of the user, so that the processing device of the authorization management information deletes the mail from the second storage module. Of course, the processing device for authorization management information may also automatically delete the mail according to a preset deletion policy.
Need to explain: the second storage module is used for storing the information content of the authorization management information (the information content is the emm of the mail), and can support the read-write operation of the mail. Specifically, the operations of reading, writing, querying, deleting, and the like may be performed on the second storage module. The storage format of each mail in the second storage module comprises: read/write status, message _ ID, group _ ID, mail data size, mail data (information content), and the like. In addition, the storage format of each mail in the second storage module may further include: a time field for indicating a time when the processing device of the entitlement management information receives the emm. Furthermore, the mails in the second storage module can be sorted according to the sequence indicated by the time field, so that the corresponding mails can be conveniently searched according to the time field. Further, the maximum value of the mails which can be stored in the second storage module can be preset, and when the number of the mails reaches the maximum value, the mail which is received at the earliest time is deleted.
In the second case: referring to fig. 5, the information content in emm _ T is a notification, and the specific process is as follows.
(1) If emm _ T is personal information and the content of the personal information is a notification (denoted as emm _ T _ image), the method specifically comprises the following steps: decrypting the emm _ T _ image, analyzing the decrypted emm _ T _ image and storing the information content of the emm _ T _ image. Further, in this process, the processing device that authorizes management information may collect the information of the extra _ message _ format _ version field in the emm _ T _ image and store the information in the information list, or certainly, the information may not be stored in the form of the information list, as long as the information exists in a preset storage space.
For example, as to emm _ T _ image, since emm _ T _ image is encrypted, emm _ T _ image is sent to the smart card for decryption, and decrypted emm _ T _ image returned by the smart card is received and stored. And collecting the information of the extra _ message _ format _ version field in the emm _ T _ image and storing the information into the information list.
(2) If emm _ T is shared information and the content of the information is notification (denoted as emm _ T _ message), the method specifically includes: and detecting whether the emm _ T _ message is authorization management information for the machine, if so, analyzing the emm _ T _ message and storing the information content of the emm _ T _ message, and otherwise, discarding the emm _ T _ message.
For example, for em _ T _ message, first, format _ version in em _ T _ message is acquired, and whether the same information as the format _ version exists is searched from the information list for storing the extra _ message _ format _ version information. If yes, the notification is the notification data corresponding to the local computer and is stored; otherwise, the notification is discarded. In the step, the emm information is filtered again, redundant emm information is discarded, cache resources are further saved, and the data processing rate of the processing device for the authorization management information is improved.
Whether the emm _ T is the above-mentioned emm _ T _ image or emm _ T _ message, analyzing and storing the information content of the emm _ T may include: storing the emm _ T in a third storage module, when the number of the authorization management information in the third storage module reaches a preset number, packaging the authorization management information with the preset number, storing the authorization management information content obtained after packaging in a fourth storage module, and deleting the authorization management information with the preset number in the third storage module from the third storage module.
Need to explain: in this embodiment, the third storage module is a storage space in the memory, and may be a data block, and the example may store emm _ T in the storage space in the form of an information list. The fourth storage module is a storage space in the memory, and is deleted if the user views the notification.
Furthermore, the process of packaging the preset number of pieces of authorization management information may further include operations such as extracting information content from the authorization management information, so as to store the extracted information content in the fourth storage module.
Furthermore, after the information content of the authorization management information is stored in the fourth storage module, the application can be notified to display in an event mode. Specifically, if a notification meeting the conditions is received, the notification is sent to the display device in an event mode for display, if the user confirms to watch the notification, the notification is deleted in the storage module, and if the user does not watch the notification, the notification is stored in the memory.
