In some embodiments, when an interface of an interactive application is displayed, and an instruction to select and add an interactive application control is received, the interactive application is added to the interactive application list. Exemplarily, Fig. 10 exemplarily shows a schematic diagram of another user interface provided according to some embodiments. In Figure 10, the Add Interaction application control is shown. In the embodiment of the present application, when viewing the interface of the interactive application, the user may add the currently displayed interactive application to the interactive application list by adding an interactive application control.

In this embodiment of the application, when the interface of the interactive application is displayed, and an instruction to add an interactive application control is received, the interactive application is added to the interactive application list, and the first code of the channel corresponding to the interactive application is acquired flow. Utilize the first code stream to detect the type of the interactive application; if the type of the interactive application is a broadband application, save the first web page entry of the interactive application in the first code stream to the memory; if the interactive If the type of the application is a broadcast application, the first resource file of the interactive application in the first code stream is stored in the memory.

In the embodiment of the present application, in order to facilitate the user to view the interactive application, when the display device displays the interface of the interactive application, an instruction to add an interactive application control can be selected, so that the interactive application can be added to the interactive application list. When the user wants to watch the interactive application again, the interactive application control corresponding to the interactive application can be found through the interactive application list, and the interactive application can be started. The required data for starting the interactive application is stored in the memory, and when it is desired to view the interactive application again, the data can be directly read from the memory to start the interactive application.

In some embodiments, the first code stream is used to detect whether channel information is required for starting the interactive application. In practical applications, since interactive applications and channels are bound, some interactive applications need to use channel information when starting. Exemplarily, the channel information may be a serviceid (channel identifier). It should be noted that different channels have different channel information, and a unique channel can be locked through the channel information. If channel information is needed, the channel information of the channel to which the currently playing program belongs is stored in the memory.

In some embodiments, the user can play the programs of the channel by controlling the buttons on the device. If an instruction to select and add application control is received when the interface of the interactive application corresponding to the channel is displayed before. When the display device plays the channel again, it is detected whether the data required for starting the interactive application corresponding to the played channel is stored in the memory. If the display device has already stored the data required for starting the interactive application, the type of the interactive application corresponding to the played channel is detected. If the type of the interactive application is a broadband application, the fourth web page entry is obtained according to the third code stream of the played channel. Detecting whether the fourth webpage entry is the same as the first webpage entry stored in the memory. If they are the same, the first web page entry is not updated. If not, use the fourth webpage entry to update the first webpage entry. If the type of the interactive application is a broadcast application, the third resource file is acquired according to the third code stream of the played channel. Detecting whether the third resource file is the same as the first resource file stored in the memory. If they are the same, the first resource file is not updated. If not, then use the third resource file to update the first resource file. This can ensure that the data stored in the memory is the data required for the latest interactive application startup.

Exemplarily, when the display interactive application control is in the selected state, the display device plays the program of channel A and displays the interface of the interactive application corresponding to channel A. The display device receives an instruction to switch the broadcast channel, and the display device switches from broadcast channel A to broadcast channel B. At the same time, because the code stream corresponding to channel B is received, the display device also displays the interface of the interactive application corresponding to channel B. When the interface of the interactive application corresponding to channel B is displayed, an instruction to select and add an interactive application control is received, and at this time, the data required for starting the interactive application corresponding to channel B is stored in the memory. The user continues to input an instruction to switch the broadcasting channel, and the display device switches from broadcasting channel B to broadcasting channel C. At the same time, since the code stream corresponding to channel C is received, the display device also displays the interface of the interactive application corresponding to channel C. The user continues to input the instruction to switch the broadcast channel. The instruction to switch the broadcast channel input this time instructs the display device to switch from broadcast channel C to broadcast channel B. The display device plays the program of channel B and receives the code stream corresponding to channel B at the same time. Sometimes the display device also displays the interface of the interactive application corresponding to channel B. In addition, since the data required by the interactive application corresponding to channel B has been stored in the memory before, when the program of channel B is displayed, the code stream of channel B currently played is used to detect the type of the corresponding interactive application. If the type of the interactive application corresponding to the channel B is a broadband application, the fourth web page entry is obtained according to the code stream of the currently played channel B. The fourth web page entry is compared with the first web page entry stored in memory. If they are the same, the first web page entry is not updated. If not, then use the fourth webpage entry to update the first webpage entry.
