The specific embodiment of the television of the present invention is substantially the same as the specific embodiments of the method for controlling the television program to play described below, and will not be described herein again.
Based on the hardware structure, the embodiment of the method for controlling the television program playing is provided.
Referring to fig. 2, fig. 2 is a schematic flowchart of a first embodiment of a method for controlling television program playing according to the present invention, where the method includes:
step S10, when playing the TV program containing program age lock, obtaining the age lock management information of condition receiving module;
the method for controlling the television program playing of the embodiment is applied to the television, and is particularly applied to the television with the inserted CAM card. The CAM card is a digital video condition receiving module, is a device for connecting TV set and external signal source, can convert the compressed digital signal into TV content, and can display it on TV set, and the CAM card (also called large card) and intelligent card (also called small card) are matched for use, and inserted into the digital TV integrated machine with CI (common interface) interface, so that the user can directly watch the ordered paid digital TV content without set-top box.
Currently, to limit children from watching certain television programs, certain television programs are provided with age locks by program providers. When the TV is about to play the television program with the age lock, the digital video stream of the television program is analyzed to obtain the corresponding age lock, and then the TV compares the analyzed age lock with a locally stored program age lock threshold value, so that whether the television program is allowed to be played or not can be determined according to a comparison result. For example, if the age lock of a certain program is 12, a user above 12 years old is required to watch the program, and the user below 12 years old needs to unlock the program to watch the program, and the program age lock threshold value stored locally in the TV is 10, which means that only a television program with the program age lock less than or equal to 10 can be watched, at this time, since the program age lock threshold value 12 of the program is greater than the program age lock threshold value 10 stored locally in the TV, the program must be watched by inputting a password.
In this embodiment, to prevent the conflict between the CAM and the TV control right for the age lock, when the TV broadcasts a TV program, if it is analyzed that the program includes the age lock in the video stream of the program, an inquiry request of the age lock management information is first sent to the conditional access module, and the CAM returns the current age lock management information of the CAM to the TV after receiving the inquiry request. The age lock management information includes an age lock management mode and a program age lock threshold, and the age lock management mode may be one of the following three types: the CAM does not support age lock control, the CAM only supports control over encrypted stream programs, the CAM supports simultaneous control over encrypted stream programs, and the program age lock threshold represents a maximum program age lock allowing a certain television program to be played, for example, if the program age lock threshold is 9, a television program with the age lock less than or equal to 9 is allowed to be played. In specific implementation, the age lock management mode and the program age lock threshold value can be flexibly set in advance based on the CAM menu.
Step S20, judging whether the condition receiving module supports age lock management at present according to the age lock management information;
after acquiring the age lock management information of the condition receiving module, the TV judges whether the CAM currently supports age lock management according to the age lock management information. Specifically, the age lock management mode in the age lock management information may be acquired, and if the age lock management mode currently set by the CAM is that the age lock control is not supported, it is determined that the CAM currently does not support the age lock management, and otherwise, it is determined that the CAM currently supports the age lock management.
If the CAM does not support age lock management at present, the TV controls the program age lock by itself, and the control mode is as follows: acquiring a program age lock threshold b preset based on a local menu of the TV, and controlling the playing of the television program according to the program age lock threshold b, for example, when the age lock of a certain program is 12, and the program age lock threshold b stored locally in the TV is 10<12, at this time, the TV locks the television program, and the user must input a corresponding password to watch the television program.
If the conditional access module currently supports age lock management, then go to step S30 to determine the age lock management mode currently supported by the conditional access module;
when the age lock management mode currently supported by the conditional access module is to support control over the clear stream program and the encrypted stream program, executing step S40, obtaining a program age lock threshold a preset in the conditional access module and a program age lock threshold b preset on the basis of a TV local menu, and comparing the program age lock threshold a with the program age lock threshold b;
if a > b, executing step S50, controlling the playing of the television program according to the program age lock threshold a;
and if a is not more than b, executing step S60, and controlling the playing of the television program according to the program age lock threshold b.
In this embodiment, if it is determined that the condition receiving module supports age lock management, the TV further reads an age lock management mode currently supported by the CAM from the acquired age lock management information.
When the current age lock management mode supported by the conditional access module supports control over the clear stream program and the encrypted stream program, it indicates that both the current CAM and the current TV have control right for an age lock of the program, and at this time, a program age lock threshold a preset in the conditional access module and a program age lock threshold b preset based on a local menu of the TV are obtained first, where a represents that the television program is allowed to be played only when the program age lock contained in the television program is less than or equal to a, and b represents that the television program is allowed to be played only when the program age lock contained in the television program is less than or equal to b, and the clear stream program and the encrypted stream program are two different types of television programs, the clear stream program is an unencrypted television program and can be viewed without paying, and the encrypted stream program is an encrypted television program and can be viewed with paying.
Comparing a program age lock threshold value a with a program age lock threshold value b, and if a > b, controlling the playing of the television program according to the program age lock threshold value a; and if a is not more than b, controlling the playing of the television program according to a program age lock threshold b. Therefore, the playing of the television program is controlled according to the larger of the program age lock threshold in the CAM and the TV, so that the control right conflict is avoided, and the watching limiting effect of the television program can be ensured.
By the mode, for a certain program, when the program age lock in the program information meets the program locking conditions set by the CAM and the TV, only one menu is popped up to enable a user to unlock the program, namely the TV local menu or the CAM menu, so that the interaction between the user and the TV is simpler and more humanized.
Further, referring to fig. 3, fig. 3 is a schematic diagram of a refinement step of step S50 in fig. 2. The step S40 may include:
step S51, acquiring and analyzing the program information of the television program to obtain a program age lock c of the television program;
step S52, comparing the program age lock c with the program age lock threshold a;
if c is less than or equal to a, executing step S53 to control the television program to be played normally;
if c > a, executing step S54, popping up a password input window corresponding to the conditional access module for the user to input a password, controlling the television program to be played normally when the password input by the user is correct, otherwise, not playing the television program.
In this embodiment, the specific way of controlling the playing of the television program according to the program age lock threshold a is as follows: firstly, acquiring and analyzing program information of a television program to obtain a program age lock c of the television program, and then comparing the program age lock c with a program age lock threshold value a; if c is less than or equal to a, controlling the television program to be played normally; if c is larger than a, popping up a password input window corresponding to the condition receiving module for a user to input a password, controlling the television program to be played normally when the password input by the user is correct, and otherwise, not playing the television program.
For example, when the obtained program age lock c is 12 and the program age lock threshold a is 10, the TV locks the currently upcoming television program, such as displaying a black screen, and simultaneously pops up a password input window corresponding to the CAM to prompt the user to input a password, where the password may be a parent password preset by a parent, and when the user inputs the password correctly, the television program is unlocked and played normally, otherwise, the television program is kept locked. For another example, when the obtained program age lock c is 12 and the obtained program age lock threshold a is 14, the TV normally plays the television program to be currently played.
It should be noted that, when a is less than or equal to b, the specific implementation of controlling the playing of the television program according to the program age lock threshold b is similar to the implementation of controlling the playing of the television program according to the program age lock threshold a, and is not described herein again.
In this embodiment, when a television program including a program age lock is played, the age lock management information of the conditional access module is acquired; judging whether the condition receiving module supports age lock management currently or not according to the age lock management information; if yes, determining the age lock management mode currently supported by the condition receiving module; when the current supported age lock management mode of the conditional access module supports control of clear stream programs and encrypted stream programs, acquiring a preset program age lock threshold value a and a preset program age lock threshold value b based on a TV local menu in advance in the conditional access module, and comparing the program age lock threshold value a with the program age lock threshold value b; if a > b, controlling the playing of the television program according to the program age lock threshold value a; and if a is not more than b, controlling the playing of the television program according to the program age lock threshold b. Through the mode, the television program can be controlled to be played according to the program age lock threshold value a preset in the condition receiving module or the program age lock threshold value b set based on the local menu of the TV, so that the problem that the condition receiving module and the TV conflict with each other in control over the television program age lock is solved.
Further, based on the above first embodiment of the method for controlling tv program playing of the present invention, a second embodiment of the method for controlling tv program playing of the present invention is provided. In this embodiment, after the step S30, the method may further include:
when the current age lock management mode supported by the conditional access module only supports the control of the encrypted stream program, judging whether the television program is the encrypted stream program;
if yes, acquiring a program age lock threshold value a preset in the condition receiving module and a program age lock threshold value b preset on the basis of a TV local menu, and comparing the program age lock threshold value a with the program age lock threshold value b;
if a > b, controlling the playing of the television program according to the program age lock threshold value a;
if a is not more than b, controlling the playing of the television program according to the program age lock threshold b;
if not, acquiring a program age lock threshold b preset based on a TV local menu, and controlling the playing of the television program according to the program age lock threshold b.
In this embodiment, when the current age lock management mode supported by the conditional access module only supports control over a confidential flow program, it is determined whether a television program to be currently played is a confidential flow program, specifically, a video stream of the television program is analyzed, and if the television program includes corresponding encryption information, the television program is determined to be a confidential flow program; if the television program to be played is a dense stream program, it is indicated that both the CAM and the TV currently have a control right for the age lock of the program, and at this time, one of the CAM and the TV needs to be selected to control the age lock of the program. On the contrary, if the television program to be played is a clear stream program, the CAM does not have the control right for the age lock of the television program, and at the moment, the TV controls the age lock of the television program, namely, a program age lock threshold b preset based on a local menu of the TV is obtained, and the playing of the television program is controlled according to the program age lock threshold b.
In the embodiment, the situation of the clear stream program is considered, and through the manner, no matter the television program containing the program age lock is the clear stream program or the secret stream program, only one age lock control right can be ensured to exist at the same time based on the television program, so that the problem that the control of the CAM and the TV on the age lock of the television program conflicts is avoided.
Further, based on the first and second embodiments of the method for controlling television program playing, a third embodiment of the method for controlling television program playing of the present invention is provided.
