According to the scheme, when the tuner sends the signal data to the hardware demultiplexer, the intelligent television acquires mirror image data of the signal data sent by the tuner; filtering the mirror image data, and backing up the filtered mirror image data; and when the prompt message of inserting the video and password card is detected, sending the backed-up mirror image data to the video and password card. In the embodiment, when the video and password card is inserted, the signal data sent by the tuner is mirrored, and the mirrored signal data is backed up, so that the condition of data filtering pause is avoided.
Based on the above hardware structure, the embodiment of the data processing method of the present invention is provided.
Referring to fig. 2, fig. 2 is a flowchart illustrating a data processing method according to a first embodiment of the present invention.
In a first embodiment, the data processing method includes the steps of:
step S10, when the tuner sends the signal data to the hardware demultiplexer, the smart television acquires mirror image data of the signal data sent by the tuner;
it should be noted that, in a general case, the smart television sends the signal data sent by the tuner to the hardware demultiplexer for demultiplexing, where the signal data sent by the tuner is data obtained by encoding, multiplexing, and modulating the signal data in the TS stream, and the hardware demultiplexer may parse the signal data in the tuner through demultiplexing, and separate out required data, that is, perform classification processing on the signal data, for example, the data sent by the tuner is signal data obtained by packetizing audio and video, and the hardware demultiplexer may unpack the audio data and the video data, and separate out the audio data and the video data, respectively.
It is to be understood that, in an embodiment, when the tuner sends the signal data to the hardware demultiplexer, the signal data sent from the tuner is mirrored, that is, a copy of the mirrored data identical to the data sent from the tuner is backed up, so that the signal data in the tuner is backed up so as to be recoverable by using the mirrored data when the data is lost.
In order to ensure the consistency of data, in this embodiment, the signal data sent from the tuner is used as mirror image data, and the mirror image data is sent to a preset area, so that the mirror image data is stored.
Step S20, filtering the mirror image data, and backing up the filtered mirror image data;
it should be noted that the filtering may be performed by sending signal data with smaller data size into a soft demultiplexer for processing through a preset condition, and the filtered mirror image data may be at least one of a Conditional Access Table (CAT), a Program Association Table (PAT), a Program Map Table (PMT), a Network Information Table (NIT), a System equipment Table (SDT), a bouquet Association Table (bouquet Association Table, BAT), a Time Information Table (Event Information Table, EIT), a Time and Date Table (Time & Date Table, TDT), and a Time Offset Table (TOT), so as to represent signal data in the form of data of important data Information, and certainly, in a specific implementation, the filtered mirror image data may further include other data, this embodiment is not limited in this regard.
As shown in a schematic diagram of a signal processing flow of the smart television shown in fig. 3, when the smart television receives a radio frequency signal, the radio frequency signal is correspondingly processed by the tuner, when the signal data output by the tuner does not have a privacy card, that is, when the signal data reflecting connectivity is represented as 1, in this case, the signal data output by the tuner passes through a demultiplexer 0 to a decoder, so as to decode an audio/video signal and output the audio/video signal, when the privacy card is inserted, that is, when the signal data reflecting connectivity is represented as 0, in this case, the signal data output by the tuner passes through the privacy card, and outputs the processed signal to a demultiplexer 1 connected to the USB interface, and the demultiplexer 1 decodes the audio/video signal data through the decoder.
In a specific implementation, in a state that the video card is inserted or pulled out, the smart television performs mirroring on signal data tuned in the tuner, and sends the mirrored signal data to the soft demultiplexer for filtering, so that signal data reflecting a data flow direction and a transmission event are reserved, and data recovery is facilitated according to the filtered data during data recovery.
And step S30, when the prompt message of inserting the video and audio card is detected, sending the mirror image data after backup to the video and audio card.
It should be noted that the prompt information may be prompted by a parameter Bypass, or may be prompted by other parameter information, which is not limited in this embodiment, for example, when Bypass is 0, it indicates that the secret card is inserted, and when Bypass is 1, it indicates that the secret card is dialed out, so that the state of the secret card can be obtained through the prompt information, and through the current state, corresponding processing may be performed on the backed-up data.
In specific implementation, the mirror image data after backup can be stored in a preset storage area, when prompt information for inserting the video and audio card is detected, the mirror image data after backup in the preset storage area is extracted, and the mirror image data after backup is sent to the video and audio card, so that the mirror image data after backup can be extracted from the preset storage area, and the situations of data filtering pause and overtime are avoided when the video and audio card is inserted.
Through the technical scheme, the Bypass value change can exist in the process of inserting and pulling the video-secret card in the channel searching process, and the TS flow passes through the video-secret card or does not pass through the video-secret card. Without the soft demultiplexer, the segment (section) data is not filtered during the time period of TS stream switching. With the soft demultiplexer, the data can be stably and continuously filtered without being influenced.
In the playing process, NIT is updated, when a video card is plugged and unplugged, if no soft demultiplexer exists, the value of Bypass is changed, the section data cannot be filtered in the TS stream switching time period, and the filtered data is overtime. The data can be stably and continuously filtered without being influenced by the soft demultiplexer.
In the process of collecting Electronic Program Guide (EPG) information, when a video card is plugged in or pulled out, if no soft demultiplexer is provided, the value of Bypass changes, and the time period of TS stream switching cannot filter section data. The data can be stably and continuously filtered to the data without being influenced by the soft demultiplexer.
In the data downloading process, when the video card is plugged and unplugged, a soft demultiplexer is not arranged, the value of Bypass is changed, and section data cannot be filtered in the TS stream switching time period, so that the full data can be received only by waiting for the next cycle of the code stream. The soft demultiplexer can stably and continuously filter the data without being influenced.
According to the scheme provided by the embodiment, when the tuner sends the signal data to the hardware demultiplexer, the smart television acquires mirror image data of the signal data sent by the tuner; filtering the mirror image data, and backing up the filtered mirror image data; and when the prompt message of inserting the video and password card is detected, sending the backed-up mirror image data to the video and password card. In the embodiment, when the video and password card is inserted, the signal data sent by the tuner is mirrored, and the mirrored signal data is backed up, so that the condition of data filtering pause is avoided.
Further, as shown in fig. 4, a second embodiment of the data processing method according to the present invention is proposed based on the first embodiment, and in this embodiment, after step S30, the method further includes:
and step S40, when the prompt message of pulling out the video and audio card is detected, the transmission of the mirror image data after backup to the video and audio card is stopped.
It should be noted that the prompt information may be prompted by a parameter Bypass, or may be prompted by other parameter information, which is not limited in this embodiment, for example, when Bypass is 0, it indicates that the secret card is inserted, and when Bypass is 1, it indicates that the secret card is dialed out, so that the state of the secret card can be obtained through the prompt information, and through the current state, corresponding processing may be performed on the backed-up data.
In a specific implementation, when a prompt message indicating that the privacy card is pulled out is detected, that is, when it is detected that Bypass is 1, it indicates that the privacy card is pulled out, in this case, the corresponding processing on the backed-up data is stopped, the signal data sent from the tuner is directly sent to the demultiplexer 0, and as shown in fig. 3, the data sent from the tuner is sent to the demultiplexer 0 when Bypass is 1, so that the transmission of the original signal data is resumed when the privacy card is pulled out.
According to the scheme provided by the embodiment, when the smart television detects the prompt message that the video-audio card is pulled out, the backup mirror image data is stopped being sent to the video-audio card, so that the backup mirror image data is prevented from being sent all the time.
Further, as shown in fig. 5, a third embodiment of the data processing method according to the present invention is proposed based on the second embodiment, and in this embodiment, before the step S30, the method includes:
step S301, calling a bottom layer program of the android system to enable the bottom layer program to monitor the plugging and unplugging state of the video and password card, and generating corresponding prompt information when the state changes.
It should be noted that the corresponding prompt information is obtained through interaction between the bottom layer and the application layer, that is, by calling a bottom layer program of the android system, for example, when the smart television detects that the video/audio card is plugged, the plugging state of the video/audio card can be monitored through the bottom layer, and when the state changes, a corresponding prompt message is generated.
In a specific implementation, the bottom layer program may be an interface program, and the current working state of the video-audio card is obtained by inserting and pulling the video-audio card into and out of the interface, where the change in the state may be that the video-audio card is pulled out when in an insertion state or enters an insertion state after being pulled out, so that the current interface information can be obtained in real time.
Further, the step S30 specifically includes:
step S302, calling the bottom layer program to enable the bottom layer program to generate an insertion parameter of the video-audio card when receiving an insertion request of the video-audio card, and sending the insertion parameter to a control program of an application layer;
it should be noted that the insertion parameter may be a state identifier indicating a current interface, and the state identifier is sent to a control program of an application layer, so that whether the backed up mirror image data is sent is controlled by the control program.
Step S303, calling the control program to send the backed-up mirror image data to the video/audio card when the control program receives the insertion parameter.
Further, the step S40 specifically includes:
step S401, calling the bottom layer program to enable the bottom layer program to generate a switching parameter of the video-encryption card when receiving a pulling-out request of the video-encryption card, and sending the switching parameter to a control program of an application layer;
step S402, calling the control program to stop sending the backup mirror image data to the video-audio card when the control program receives the switching parameter.
According to the scheme provided by the embodiment, the smart television can monitor the state of the video-audio card through the bottom layer, when the state meets the preset condition, the backed-up mirror image data is sent to the video-audio card, and the sending of the data is stopped through switching the parameters, so that the data transmission can be effectively controlled.
Further, as shown in fig. 6, a fourth embodiment of the data processing method according to the present invention is proposed based on the first embodiment, the second embodiment and the third embodiment, in this embodiment, the description is made based on the first embodiment, and the step S20 specifically includes:
step S201, a preset filter program is called to filter the mirror image data by the preset filter program, and the filtered mirror image data is backed up.
It should be noted that the filter program may be a preset condition stored in advance, for example, the soft demultiplexer is guaranteed to store section data after filtering, and may also be a filter program called by another device, which is not limited in this embodiment.
Further, before the step S201, the method further includes:
step S202, a program storage instruction is obtained, and a preset filtering program is stored according to the program storage instruction.
It can be understood that, before data filtering is performed by the filter program, the filter program needs to be stored, and the filter program can be modified and optimized for a preset condition, so that the filter program can be flexibly maintained.
According to the scheme provided by the embodiment, the smart television is provided with the filtering program on the soft demultiplexer, the section data is filtered by the filtering program, and the filtered mirror image data can be used for ensuring that the data can be stably and continuously filtered when the video-audio card is plugged and unplugged.
