s601, responding to a program switching instruction, and monitoring a target position in code stream data of a program to be played.

The program switching instruction is used for indicating to switch from the current program to the program to be played.

The target positions are all positions containing program grade information in the code stream data, the channel modes of the display equipment are different, and the corresponding target positions are different.

For example, if the channel format is 1.0, the target location includes: event information table (Event Information Table, EIT), program map table (Program Map Table, PMT) and extended data service (XDS) segments. Wherein, EIT provides event name, start time, time length, running state, etc.; information contained in a program of one channel, for example, which streams the program of one channel is composed of and the types of these streams (video, audio, data), identification numbers corresponding to the respective streams in the specified program, and identification numbers corresponding to the program clock references (Program Clock Reference, PCR) of the program, can be obtained by the PMT.

Therefore, all program grade information of the program to be played is obtained, and the omission of truly effective program grade information is avoided.

In some embodiments, the user operates the display device to switch the program through the intelligent device or the control device, the display device receives the program switching instruction sent by the control device, step S601 includes a flow shown in fig. 7, and fig. 7 is a second schematic flow diagram of a control method for displaying the program according to the embodiment of the present disclosure:

s701, in response to a program switching instruction, judging whether to wait for program grade information.

In some embodiments, it is determined whether waiting for program rating information is required based on at least one of the following data:

(1) Whether the parental lock is opened

Specifically, when the parental lock is closed, the program grade information does not need to be waited; under the condition that the parental lock is opened, whether the program grade information needs to be waited or not can be further judged according to other data.

(2) Presetting program grade information

Optionally, if the preset program grade information exists, the user is indicated to limit the grade of the program, and waiting for the program grade information is needed; if the preset grade information does not exist, the program grade information does not need to be waited;

(3) Television channel lock or channel lock

Optionally, if the program to be played has a television channel lock or channel lock, the program grade information of the program to be played is not waited, the television channel lock or channel lock is used for locking the television channel or channel, it can be understood that the television channel or channel corresponding to the program to be played is locked, the content of the program to be played is not displayed, and therefore the program grade information is not waited;

if the program to be played does not have the television channel lock or the channel lock, judging whether to wait for the program grade information according to other data;

(4) Time lock

Optionally, if the program to be played has a time lock, which means that the specific time period of the program to be played is locked, the program grade information is not waited; if the program to be played does not have the time lock, judging whether to wait for the program grade information or not according to other data.

(5) Whether to input unlocking password of parental lock after starting up

If the unlocking password of the parental lock is input after the power-on, the program playing restriction is released, and various programs are allowed to be played, so that waiting for program grade information is not needed.

And determining whether waiting for program grade information is required according to the at least one item of data, and executing S702 in the case that waiting for program grade information is required.

And directly monitoring the target position in the code stream data of the program to be played without waiting for the program level information, without the limitation of a timer, and executing S703.

S702, triggering a timer, and monitoring a target position in code stream data of a program to be played in the duration indicated by the timer.

In general, a certain time is required for analyzing the program grade information to realize the parental lock function, and the existing display device can flash out the program picture without analyzing the program grade information, so that the use experience of a user is affected.

Illustratively, the existing display device needs 1.8s for resolving the program rating information and 1.5s for resolving and playing the program content, and the display device flashes out the program picture first in view of the user, which may cause leakage of the limited-rating program picture, and affect the implementation effect of the parental lock.

In some embodiments, in order to avoid flashing a program picture of a program to be played, an embodiment of the present disclosure provides an implementation manner, a timer is set to wait for implementation of a parental lock function, a duration indicated by the timer may be set according to a time required for historical analysis of program level information, and an exemplary time of the historical analysis of the program level information is 1.5s, and the timer is set to 2.0s, where a limitation on a duration of the timer is not specifically limited in the present disclosure. After the timer is triggered, the program picture of the program to be played is not displayed temporarily, so that the program grade information is analyzed and obtained in a short time under the condition that the experience of the user is not affected, and the program picture is prevented from flashing.

And triggering a timer under the condition that waiting for the program grade information is needed, and monitoring a target position in the code stream data of the program to be played within the duration indicated by the timer so as to wait for the program grade information.

S703, monitoring a target position in the code stream data of the program to be played.

In response to the program switching instruction, the steps S701 to S703 firstly determine whether to wait for the program level information, so as to trigger a timer when the program level information needs to be waited, thereby monitoring the program level information within the time indicated by the timer.

S602, determining target grade information with highest priority from at least one program grade information under the condition that at least one program grade information corresponding to a program to be played is obtained through monitoring.

As shown in fig. 8, fig. 8 is a flowchart of a third embodiment of a control method for displaying a program, where after step S702, step S602 may include the following sub-steps S801 to S807:

s801, whether program grade information is monitored within the duration indicated by the timer.

If the program grade information is not obtained by monitoring at the target position within the time period indicated by the timer, and the number N of the program grade information is 0, reporting the master control module, and executing steps S802-S804.

S802, analyzing the code stream data to obtain the audio data and the video data of the program to be played.

S803, performing audio and video synchronous rendering processing on the audio data and the video data.

S804, controlling the display to display video data of the program to be played, and controlling the loudspeaker to synchronously output audio data of the program to be played.

It should be noted that, when the number N of program level information is 0, the program content of the program to be played is controlled to be played, and the target position is monitored continuously in the playing process, so that when the program level information is obtained through subsequent monitoring, whether to lock or continue playing is determined again.

If the time indicated by the timer is within, monitoring to obtain program grade information. Optionally, the monitoring obtains at least one program grade information, including monitoring obtains one program grade information, and monitoring obtains a plurality of program grade information. Step S805 is performed.

S805, judging whether the number N of the program grade information obtained by monitoring is larger than 1.

If yes, it means that a plurality of program level information is obtained by monitoring, and then steps S806 to S807 are executed.

If not, it indicates that the monitoring obtains a program level information, and then returns to S702 to continue monitoring for the target position in the code stream data of the program to be played.

Embodiments of the present disclosure provide an implementation that continues to monitor a target location within a time period indicated by a timer to wait for new program level information until the time period indicated by the timer is exceeded. When the new program level information is obtained by monitoring within the time period indicated by the timer, the specific execution logic is the same as that described below, and the disclosure is not repeated here. And judging whether to continue playing or locking the program to be played according to the program grade information under the condition that more program grade information is not monitored and obtained after the time indicated by the timer is exceeded.

The embodiment of the present disclosure provides another implementation manner, which directly determines whether to play or lock the program to be played according to the program level information.

S806, it is determined whether the plurality of program level information are identical.

Alternatively, whether the latter program rating information is identical to the former program rating information is sequentially compared in time order.

If the latter program grade information is the same as the former program grade information, returning to step S801, continuing to monitor the target position within the time indicated by the timer, and waiting for the new program grade information until the time indicated by the timer is exceeded. If the new different program grade information is obtained through monitoring within the time length indicated by the timer, comparing the priority of the program grade information to select target grade information with the highest priority, wherein the priority is configured by a program provider according to the program content and is used for indicating the effectiveness degree of the program grade information, and the larger the priority is, the more accurate and effective the program grade information is; if the new different program grade information is not monitored within the time indicated by the timer, judging whether to play or lock the program to be played according to the same program grade information.

If the latter program rating information is different from the former program rating information, it indicates that the program rating information is changed, and then S807 is performed.

S807 compares the priorities of the plurality of program rank information, and selects the target rank information with the highest priority from the plurality of program rank information to execute the subsequent step S603.
