Description

Method and device based on conditional receiving module program identification

Technical field

The invention belongs to the technical field of digital television, and in particular relates to a method and device for program identification based on a conditional receiving module.

Background technique

The digital TV all-in-one includes a host (Host) and a CAM card with conditional access (Conditional Access) Module) two parts, the two are connected through the PCMCIA interface, and communicate according to the protocol specified by the DVB-CI related standards. When existing radio and television operators play radio programs on the front-end, they often restrict users from watching the corresponding programs because the end users do not handle the services related to the broadcasting and TV operators. However, for users who have already handled the related services of the broadcasting and TV operators, all programs can be performed. Watching, the user does not see the relevant program information because the program is not authorized.

For the current viewing restrictions, the broadcasting and television operators set the adult-level program viewing rights for the adult-level programs and the conditional receiving module (the CAM module) that are played in different age groups. You need to enter the PIN code to watch the corresponding adult level. The program can also restrict the user's viewing of the program by setting the corresponding viewing authority, and restrict the viewing of the ordinary user by the administrator authority.

However, the existing method mainly performs authorization management for adult programs or other programs that need to be restricted for viewing, and requires the user to set the programs one by one, which increases the cumbersomeness of the user operation and cannot be based on the user's operating habits and viewing. The real-time status of the program controls the playback of the corresponding program. Moreover, the prior art can only single-scramble selected encrypted programs from the user, or corresponding paid programs, and cannot properly utilize the television program resources. Once the user leaves the television screen for a long time, resources are wasted. Watching programs without limits can also cause eye fatigue and is not conducive to health.

technical problem

Embodiments of the present invention provide a method and apparatus for program identification based on a conditional receiving module, which aims to solve the problem of eye fatigue and waste of resources caused by the existing unrestricted viewing program.

Embodiments of the invention

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

FIG. 3 is a method for watching a television program provided by the prior art. As shown in FIG. 3, the current control method for the charging program is a scrambling method, and only the user pays to descramble the encrypted TS stream. The specific steps are as follows:

S301: The host acquires the program information of the carrier, and sends the program list information to the CAM card through the CI communication.

S302: The CAM card receives the program information from the host host, and determines whether the program is a scrambled program. If it is a scrambled program, the process proceeds to step S303. If it is clear stream, the process directly jumps to step S305, and the host host plays the clear stream program.

S303: The CAM card receives the scrambled stream that is sent by the host host through the TS interface.

S304: The CAM card descrambles the encrypted program, and returns the descrambling information to the host host.

S305: The host host plays the TV program normally.

In the embodiment of the present invention, the setting of the restricted program and the setting of the descrambling instruction of the descrambling corresponding limiting program are provided on the basis of the prior art, and the triggering condition of the descrambling request can also be customized according to the user's use requirement, and the setting is performed. After the parameters are stored, the user is requested to feedback the descrambling command to perform descrambling if the preset trigger condition is met. If the system does not receive the corresponding feedback information, the system stops the descrambling or even causes the television terminal to enter the sleep state, which can effectively control the user to watch. The time of the TV avoids visual fatigue, and it can also save power to avoid wasting resources when the user does not watch TV.

Embodiment 1

1 is a flowchart of a method for condition recognition of a program based on a conditional receiving module according to Embodiment 1 of the present invention. A method for program identification based on a conditional receiving module according to an embodiment of the present invention is specifically described below with reference to FIG. a television terminal, the television terminal is pre-set with a program for restricting viewing and a descrambling instruction for releasing the restriction of the corresponding program, as shown in FIG. 1, the method includes:

S101, when the program being played is a program limited to watch, the preset condition parameters are collected, and the process proceeds to step S102;

S102, determining whether the collected condition parameter meets the preset trigger condition, if yes, then go to step S103; otherwise, jump to step S101 and cycle this step S102;

S105, the descrambling of the program;

S106. Stop descrambling the program.

The step of descrambling the descrambling of the program is specifically: the CAM receives the scrambled stream from the Host through the TS interface; the CAM performs descrambling on the encrypted TS through the descrambling module, and returns the descrambling information to the Host; the Host receives the CAM After the descrambled transparent TS stream is returned or receives the clear stream through the CAM, the Host host continues to play the corresponding TV program.

The trigger condition may be selected according to an option provided by a manufacturer, and the available trigger conditions include, but are not limited to, a continuous play time condition, a power usage condition, a user operation condition, and the like. Preferably, the trigger condition may be a continuous play time condition, and the corresponding condition parameter is a time period during which the television is continuously played.

The program for restricting viewing includes a scrambled program for the program limited to watch preset by the television terminal and the descrambling command for canceling the restriction of the corresponding program, and the descrambling command includes but is not limited to the confirmation command and the password command. When a password command is selected as the confirmation command, the password includes, but is not limited to, an administrator identity authentication (eg, facial feature recognition, iris recognition), a character password, a gesture password, and the like.

Alternatively, the method further includes:

When receiving the setting instruction of the trigger condition, the user is prompted to input a trigger condition and a program corresponding to the restriction;

Receive and save the input trigger conditions and the corresponding programs that need to be restricted.

An example according to the present embodiment is shown in FIG. 6. FIG. 6 is a flowchart of a method for condition recognition module recognition based on an embodiment of the present invention, the method comprising the following steps:

S601: The Host obtains the program information of the operator, and sends the program list information to the CAM through the CI communication.

S602: The CAM receives the information from the Host program, and determines whether the program is a scrambled program. If it is a scrambled program, the flow proceeds to S603.

S603: The Host transmits the encrypted stream to the CAM through the TS interface to request descrambling, and the CAM receives the scrambled stream that the Host transmits through the TS interface.

S604: determining that the terminal user is in the CAM Whether the CI menu is set to watch the program restriction time. If yes, go to step S605, if no, go to step S610.

S605: The end user customizes the time for watching the television program.

If the user does not manually set the viewing time, the CAM will pop up a message prompting to remind the user whether to use the default time limit. If the user does not select, the user is prompted to manually set; if the user does not respond to any action, the CAM works normally, no Subject to conditions.

S606: The CAM determines whether there is a response operation from the end user for a limited time. If yes, the process proceeds to step S613 to continue watching the television program. If not, the process proceeds to step S607 to prompt the user whether to continue watching the television program.

S607: After the pop-up message prompts, the CAM does not capture the corresponding response action within a limited time range, and the CAM stops descrambling.

S608: There is no response action in the three prompts.

S609: The CAM stops descrambling, and the Host enters a sleep state.

S610: The CAM pop-up message prompts whether it is determined whether the limited viewing time is set to the system default time limit. If yes, the process proceeds to step S606, otherwise, the process proceeds to step S611.

S611: The CAM pop-up message prompts whether the user needs to manually set the time limit condition, and if yes, proceeds to step S606, otherwise proceeds to step S612.

S612: The television program is normally played.

S613: The CAM receives the scrambled stream from the Host through the TS interface.

S614: The CAM performs descrambling on the encrypted TS by using the descrambling module, and returns the descrambling information to the Host.

S615: The Host receives the descrambled transparent TS stream returned by the CAM or receives the clear stream through the CAM, and the Host plays the corresponding TV program according to the user selection.

After the CAM prompts the pop-up message to capture the response action within the limited time range, the CAM continues to work normally, and the Host continues to play the TV program.

In the case of CAM normal descrambling, the user can enter CI Menu selects CAM to prompt the user to watch the program time limit, and CAM exits CI according to the user's choice to keep the corresponding setting information. Menu setting menu, the corresponding settings take effect, the corresponding setting information is stored in the CAM Flash Memory, power on again, the relevant settings will not be lost; similarly, the user can enter CI Menu to modify the set time. If the user does not limit the CAM prompt time, the CAM prompts the user to watch the television program according to the default time provided by the factory setting.

If CAM only needs to select the corresponding program, it can set the viewing right or the viewing time. After exiting the setting menu, CAM will set the information and the service of the corresponding program. The ID is bound, and once the user enters the limited program, the CAM does not descramble the limited program. The limited program can be released by entering the administrator authority. Once the verification is passed, the CAM will descramble the program, and the user can watch the TV program normally.

In this embodiment, the CAM does not capture the corresponding feedback, and the CAM stops descrambling the current program, wherein the restricted program such as the adult program, the children program or other viewing restrictions of the encrypted or unencrypted program can be applied to all types. The television program viewing setting, in this embodiment, obtains the response action from the terminal user by automatic judgment, and the CAM selects whether to continue to descramble the current television program, and the program control can be realized without additional hardware control.

FIG. 7 is a flowchart of a method for condition recognition of a program based on a conditional receiving module according to another embodiment of the present invention. As shown in FIG. 7, the method for preset limiting a program to be viewed includes the following steps:

S701: The Host obtains the program information of the operator, and sends the program list information to the CAM through the CI communication.

S702: The user analyzes the program content, and selects a program that needs to set a viewing time limit. Among them, programs that need to be restricted, such as animation programs, variety shows, and other programs that children prefer, or other programs that require payment, can play a role in controlling their own consumption.

S703: The CAM prompts the user whether to set the television program viewing restriction condition according to different limited time.

S704: The user enters the CAM CI menu in the normal descrambling of the program that needs to set the viewing time limit, and passes the CAM CI. The Menu can manually select and set different program viewing time limits, and can control the viewing of the program according to the user-defined time or duration.

S705: Exiting the setting menu, saving the setting information in step S704, and immediately after exiting the setting menu, the CAM can prompt the remaining viewing time of the current program through the bullet box.

S706: After the setting is successful in step S705, the current program enters the restricted viewing state. When the viewing program is limited, the CAM will pop up a message prompting, and the user can perform corresponding operations according to the prompt message.

The analysis program content in the step S702 is mainly to filter the programs of the same type, for example, by extracting keywords preset in the program name (for example, variety shows, cartoons), and displaying the programs of the same type together, so that the user can quickly Make a choice.

This embodiment provides an implementation manner of two descrambling instructions, which are set by the user according to actual needs. When the trigger condition is satisfied and the CAM card does not capture the corresponding action (when confirming the command and/or the command password), the descrambling of the currently played program is stopped so that the television program does not continue to play. In this embodiment, the user can select a corresponding descrambling mode according to the actual situation and needs of the user, thereby bringing convenience and a new experience to the user.
