An embodiment of the present application provides a digital television system, as shown in fig. 1, including: a front-end device 100, a one-way set-top box 200 and a terminal 300; wherein the content of the first and second substances,
the front-end device 100 is configured to issue a startup picture file, where a corresponding relationship between a region code and a startup picture address is stored in the startup picture file;
the one-way set-top box 200 is configured to obtain the boot-up picture file, obtain a boot-up picture address corresponding to the built-in region code according to the built-in region code of the one-way set-top box 200 and the boot-up picture file, obtain and store a boot-up picture corresponding to the boot-up picture address according to the boot-up picture address, and control the terminal 300 to display the stored boot-up picture at a start-up stage;
the built-in region code is a region code identifying a region in which the one-way set-top box 200 is located.
It should be noted that, in the present application, the startup picture file sent by the front-end device 100 is broadcasted on the fixed frequency point of the code stream broadcasting system of the front-end device 100, so that the one-way set-top box 200 can obtain the startup picture file in the starting process of the terminal 300.
In addition, in an embodiment of the present application, the startup picture file is in a file format under a digital television broadcasting protocol (i.e., an OC file), and the content of the file may be a json (JavaScript Object Notation) text. In a preferred embodiment of the present application, the front-end device 100 broadcasts the startup picture file on a fixed frequency point, And the one-way set-top box 200 requests the startup picture file through AJAX (Asynchronous Javascript And XML), And because of the Asynchronous request characteristic of AJAX, the step of requesting the startup picture file is implemented on the basis of not affecting other flows in the startup process of the one-way set-top box.
In one particular embodiment of the present application, as shown in FIG. 2, a possible example of json text is provided; in FIG. 2, "region1" indicates region code 1, and imageVersion "001" indicates that the current version information is 001;
and the ImageUrl is 'dvb:// 10.13.12.2/images/indexes.GIF' indicates that the path corresponding to the startup picture is dvb:// 10.13.12.2/images/indexes.jpg, and the 'regionConfig' indicates the region code configuration information.
In an actual application process, the terminal 300 displays a boot-up picture currently stored by the one-way set-top box 200 in a starting process, and at the same time, the one-way set-top box 200 acquires the boot-up picture file, acquires a boot-up picture address corresponding to the built-in region code according to the built-in region code of the one-way set-top box 200 and the boot-up picture file, and acquires and stores a boot-up picture corresponding to the boot-up picture address according to the boot-up picture address, where the boot-up picture acquired according to the boot-up picture address at this time may be the same as or different from the boot-up picture stored before this time, but regardless of whether the boot-up picture is the same or not, the terminal 300 only displays the boot-up picture stored by the one-way set-top box 200 before this time starting at a starting stage.
After the one-way set-top box 200 acquires the boot-up picture corresponding to the boot-up picture address, the acquired boot-up picture is replaced with the boot-up picture stored before, so that the problem that the memory of the one-way set-top box 200 is full due to the fact that too many boot-up pictures are stored is avoided.
It should be further noted that the digital television system issues the boot-up picture file storing the correspondence between the region code and the boot-up picture address through the front-end device 100, so that the one-way set-top box 200 can obtain the boot-up picture file, and updates the built-in boot-up picture according to the boot-up picture file and the built-in region code, so that the terminal 300 can display the boot-up picture corresponding to the region code at the start-up stage, thereby achieving the purpose of displaying different boot-up pictures on the one-way set-top boxes 200 in different regions; and the digital television system does not need to customize and store the unidirectional set-top box 200 with different startup pictures for different areas, thereby reducing the customization cost and the maintenance cost of the unidirectional set-top box 200.
