Further, the HbbTV program and the main program may be installed in the above-described display apparatus. The HbbTV program can be set up with a start-up pattern according to the actual situation. For example, the display apparatus 200 may display thereon an HbbTV program start configuration interface so that a user can configure whether the HbbTV program is automatically started when the display apparatus 200 is turned on through the configuration interface.
The display apparatus 200 may display an HbbTV program self-starting configuration interface as shown in fig. 2 on the display 275 in response to an HbbTV program configuration request input by a user through the control device 100, for example, the remote controller 100A. As shown in fig. 2, the configuration interface includes a configuration switch 41. The display device 200 may configure the configuration switch 41 to be on or off in response to user input. For example, the user may cause the display device 200 to configure the configuration switch 41 on or off in response to user input by pressing left and right direction keys of the control apparatus 100.
Specifically, when the configuration switch 41 is configured to be off, the HbbTV program is not automatically started when the display apparatus 200 is turned on, but is started when the user actively starts. When the configuration switch 41 is configured to be on, the HbbTV program is automatically started when the display apparatus 200 is turned on.
It should be noted that when the HbbTV program is configured to be self-started when the display apparatus is turned on, the HbbTV program is not normally turned off and is started again during the operation of the display apparatus except for an abnormal situation such as an operation failure.
In the following embodiments, the HbbTV program is described as an example when the display device is turned on unless otherwise specified.
In some embodiments, the display device as described above is started, typically with the main program starting before the HbbTV program. This has the following technical problems: when the main program is started and the acquired component information is transmitted to the HbbTV program, if the HbbTV program is not started yet, the HbbTV program misses the component information transmitted by the main program when the display device is started, and the television program cannot be controlled by the HbbTV program.
As an embodiment, the above technical problem can be solved by the following solutions: and switching the television programs by switching channels or generating new component information when automatically switching the television programs after the current television programs are played so that the main program obtains the new component information and sends the new component information to the HbbTV program, and the HbbTV program controls the television programs according to the received new component information. However, this solution is cumbersome to operate.
For this reason, the present embodiment provides a program information acquisition method in a display apparatus as shown in fig. 3 to realize that the HbbTV program avoids missing component information on the premise that the HbbTV program starts later than the main program. It does not need to switch channels and wait for the completion of the playing of the current television program. The present embodiment will be described with reference to fig. 3.
Referring to fig. 3, fig. 3 is a flowchart of a method for acquiring program information in a display device according to an embodiment of the present invention. The flow is applied to the display device as described above.
As shown in fig. 3, the process may include the following steps:
in step 101, the main routine starts the HbbTV routine.
As one example, the main program and the HbbTV program may be installed in the display device in advance. The main program is used for controlling audio and video contents played by the television according to instructions input by external equipment and instructions generated in the television. The HbbTV program is used to connect to a DVB broadcasting network to receive standard broadcasted audio and video signals and to connect to the internet through a broadband interface to receive application program data and audio and video information transmitted by an application server.
As an example, during the start-up of the display device, the main program is started first, and the HbbTV program is controlled to start after the start-up is completed.
And step 102, when the HbbTV program is determined to be started for the first time, sending a program information request to the main program.
As an example, after the display device is turned on as described above, the HbbTV program is started later than the main program, so the HbbTV program may miss component information transmitted from the main program. Accordingly, it is possible to transmit a program information request to the main program through the HbbTV program to request program information including at least one of audio component information, video component information, and subtitle component information when it is determined that the HbbTV program is first started after the display apparatus is turned on.
As one example, there are a number of implementations for determining whether the HbbTV program is first initiated. Fig. 4 illustrates one implementation, which will be described in detail below, and is not repeated here.
As an example, the program information request may be for requesting only program information including component information of a currently played television program, without requesting program information including component information of other television programs. The reason for this is as follows: for the HbbTV program to control the tv program according to the component information, the HbbTV program needs to control the currently broadcasted tv program according to the component information of the currently broadcasted tv program. Therefore, if the component information obtained by the HbbTV program is not the component information of the currently broadcasted tv program, the HbbTV program cannot control the currently broadcasted tv program. Based on this, it is known that the HbbTV program does not need to acquire component information other than that of the currently broadcasted television program. Therefore, in order to avoid the HbbTV program from acquiring useless component information, the program information request may be set to only program information for requesting component information including a currently played television program.
As an example, to avoid abnormal problems such as system jamming, error in message transmission process, etc., which may result in a program information request being unsuccessfully sent to the main program. In this step, it may be configured to continuously send the program information request N times at a specified time interval, so as to ensure that the transmission process of the program information request is not affected by the above abnormal problem as much as possible. The specified time interval may be set according to actual conditions, and the present invention is not limited to this, and for example, the specified time interval is set to 1 second or 2 seconds. Likewise, N may be a positive integer greater than 0, and a specific value thereof may be set according to an actual situation, and the present invention does not specifically limit the value, for example, N is set to 2 or 3.
As one example, the program information may include at least one of video component information, audio component information, and subtitle component information of a television program. The video component information may be a picture ratio of a television program, such as 4: 3. 16: 9, etc., or the video format of the television program, such as flv, mp4, etc., or the definition of the television program, such as 720P, 1080P, etc., or the number of video frames of the television program, such as 30 frames/second or 60 frames/second, etc. The audio component information may be an audio bit rate of the played tv program, such as 16 bits, 20 bits, or 24 bits, or an audio language of the currently played tv program, such as chinese or english. The subtitle component information may be information such as a playing speed of a subtitle of a played television program, a language of the subtitle, and a format of the subtitle.
The specific content of the program information requested by the program information request may be determined according to actual circumstances, and the present invention is not limited to this specific content. For example, if the HbbTV program is used only to switch the caption language of a television program, the HbbTV program may request only caption component information without requesting other component information.
103, the HbbTV program receives program information returned by the main program; and the program information is read from the code stream by the main program and is stored.
As one example, the main program may obtain the program information in a variety of ways.
As one implementation manner, when the display device plays the first television program after being turned on, the program information of the first television program may be obtained from the television code stream through the main program.
For example, if the display device plays the first tv program 1 as the channel a after being turned on, the main program will analyze the program information of the tv program 1 from the current tv code stream.
As another implementation, when the television program played by the display device is switched, the main program may obtain program information of the television program played after the switching from the television code stream.
For example, assuming that the currently played television program of the display device is the television program 1 of the channel a, if an instruction sent by the control device for instructing to switch the channel is received, the display device may switch the currently played television program to the television program 2 of the channel B in response to the instruction. Because the television program played by the display device changes, the program information can be correspondingly determined to have changed, and then the operation of the main program for acquiring the program information is triggered, so that the main program acquires the program information of the television program 2 corresponding to the channel B from the current television code stream.
It should be noted that, after the main program has obtained the program information of the currently played television program, if the played television program is not changed, the main program does not repeatedly obtain the program information of the television program.
As an example, the main program obtains the first program information and stores the first program information at different times according to whether the display device automatically plays the television program after being turned on. If the display device automatically plays the television program after being started, the main program obtains and stores the first program information after being started. If the display device cannot automatically play the television program after being turned on, the main program can obtain and store the first program information when the display device receives a playing instruction which is sent by the control device and used for indicating to play the television program and responds to the instruction to play the television program.
That is, if the display device does not automatically play the tv program after being turned on, the main program will not obtain the program information nor store the program information until the tv program is played after the display device is turned on.
Based on the difference of whether the display device automatically plays the tv programs after being turned on, the HbbTV program obtains the first program information from the main program differently. As one implementation manner, if the display device does not automatically play the tv program after being turned on, there is no stored program information in a period from the time when the display device is turned on to the time when the tv program is played. At this time, if the program information request transmitted by the HbbTV program is received, since the tv program is not currently being broadcast, nor is any program information saved, the main program does not respond to the program information request, i.e., does not transmit program information to the HbbTV program. Accordingly, if the HbbTV program wants to obtain the first program information sent by the main program, it needs to wait for the display device to play the tv program again. As another implementation, if the display device automatically broadcasts the television program after being turned on, the main program obtains and stores the program information after being started, and then sends the program information to the HbbTV program when receiving a program information request.
As an example, the program information obtained by the main program may be stored in a memory of the display device. In the starting process of the HbbTV program, the display device may respond to the channel switching instruction for multiple times to switch the played television program for multiple times or the display device does not switch the channel, but the television program of the channel is automatically switched after being played, so that the main program can analyze and store multiple program information from the television code stream. Based on this, it is necessary to manage each program information stored in the memory to determine the program information corresponding to the currently played television program in the memory. As one implementation manner, a corresponding number may be allocated to the program information to indicate the backup order of the program information, where the program information that is backed up last is the program information corresponding to the currently played television program. As another implementation manner, the storage address may be used to indicate the backup order of each program information, for example, the program information with the largest storage address is the program information corresponding to the currently played television program. By the above method, the program information corresponding to the currently played television program can be determined from the plurality of program information backed up in the memory.
As an example, the HbbTV program specifically controls the tv program according to the program information, which may be determined according to the actual situation, and is not limited in the application. For example, if the HbbTV program is only used to adjust the caption playback speed of a television program, the HbbTV program can adjust the caption playback speed according to the caption component information. If the HbbTV program is used to switch the definition of the tv program, the HbbTV program can switch the definition of the tv program according to the video component information.
The flow shown in fig. 3 is completed.
By the flow shown in fig. 3, it is possible to prevent the HbbTV program from missing component information on the premise that the HbbTV program starts later than the main program. The control of the television program can be realized through the HbbTV program without switching channels or waiting for the completion of the playing of the current television program.
Next, how to determine the HbbTV program as the first start in step 102 will be described with reference to fig. 4. Referring to the flow shown in fig. 4, the method may include the following steps:
at step 1021, the current value of the flag associated with the HbbTV program is checked.
As an example, since the HbbTV program can smoothly receive the component information sent by the main program after being started for the first time, the HbbTV program only needs to actively send a program information request to request missing program information of a currently broadcasted tv program, and then does not need to actively send a program information request to request program information that is not missed.
Based on this, it is possible to manage whether the HbbTV program needs to transmit a program information request by setting a flag associated with the HbbTV program. Specifically, a first value for indicating that the HbbTV program is first started and a second value for indicating that the HbbTV program is not first started may be set for the flag, and whether the HbbTV program is first started may be determined by checking a current value of the flag. In a specific implementation, values of the first value and the second value may be set according to an actual situation, and the present invention does not limit the values, for example, the first value is set to 0, and the second value is set to 1.
As one example, a flag bit associated with the HbbTV program may be set in memory. The value of the flag is set to a first value after each power-on of the display device to indicate that the HbbTV program is first activated.
Step 1022, if the current value is a first value, it is determined that the HbbTV program is first started.
As an example, if the flag associated with the HbbTV program is checked to be a first value at present, the HbbTV program can be determined to be started for the first time, and a program information request can be further sent to the main program through the HbbTV program to request program information of a currently broadcasted tv program.
And step 1023, after the HbbTV program sends a program information request to the main program, modifying the current value of the flag bit from a first value to a second value, wherein the second value is used for indicating non-first starting.
As an example, to avoid the HbbTV program from constantly sending program information requests to the main program, after the HbbTV program sends a program information request to the main program, the current value of the flag may be modified to a second value indicating a non-first start, such that the HbbTV program no longer sends a program information request to the main program.
And step 1024, if the current value is the second value, waiting for the program information to be sent to the program by the main program by the Hbbtv program.
As an example, if it is checked that the flag associated with the HbbTV program is currently the second value, it indicates that the HbbTV program has sent the program information request to the main program, and the program information request does not need to be sent to the main program again, but the main program may wait for the transmission of the program information to the main program after obtaining the program information.
The flow shown in fig. 4 is completed.
