Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
Some embodiments of the disclosed picture display method are first described with reference to fig. 1.
Fig. 1 shows a flow diagram of a picture display method according to some embodiments of the present disclosure. As shown in fig. 1, the present embodiment includes steps S102 to S104.
In step S102, when the set-top box loads the EPG interface, the picture identifier of each picture in the EPG interface is used to query a locally stored picture control policy table, where the picture control policy table includes a mapping relationship between the picture identifier and a picture display attribute.
And after the user selects the EPG interface through the remote controller, the browser in the set-top box loads the EPG interface. At this time, the set-top box inquires the picture control policy table. In the picture control policy table, the picture identifier may be, for example, an ID or a URL of a picture, and the picture display attribute may be specifically displayed or hidden. The picture control policy table may be specifically as shown in table 1.
TABLE 1
| Identification 1(ID1, URL1) | Picture display attribute 1 (hidden) |
| Identification 2(ID2, URL2) | Picture display Property 2 (display) |
| …… | …… |
In step S104, the set-top box displays or hides each picture in the EPG interface according to the inquired picture display attribute of each picture in the EPG interface.
For example, when the picture displayed on the EPG page is a picture that needs to be shut down, the picture is hidden, and when the picture displayed on the EPG page is a picture that needs to be displayed, the picture is displayed. It will be understood by those skilled in the art that hiding a picture can be achieved by setting textfield of the picture position to be hidden.
In this embodiment, a display policy for a picture is defined according to a picture identifier and a picture display attribute. The method is applied to IPTV service, and can realize automatic display and automatic hiding of the designated picture in the EPG interface. When the picture in the EPG interface is tampered and other emergencies, the appointed picture can be automatically off-line, and therefore the safety of the IPTV service is improved.
In some embodiments, the picture control policy table is the first extended JS script, the picture identifier is a picture identifier parameter carried by the first extended JS script, and the picture display attribute is a picture display attribute parameter carried by the first extended JS script. Correspondingly, in step S102, the first extended JS script may be called, and a mapping relationship between the picture identification parameter and the picture display attribute parameter carried by the first extended JS script is obtained.
For example, the set-top box locally stores the first extended JS script ImageSetConfig. When the terminal loads the EPG page, the first extended JS script can be called by CTCSetConfig, CTCGetConfig and other methods, and the mapping relation between the picture identification parameter and the picture display attribute parameter carried by the first extended JS script is read. Then, the defined dynamic strategy is analyzed, whether the offline operation is executed to the current presented picture is judged,
according to the embodiment, the picture control strategy table can be added in the form of the JS script expansion for the calling of the set-top box on the premise of not influencing the original service of the IPTV service system, so that the rapid automatic offline of the appointed picture in the IPTV service is realized while the original IPTV service platform is not changed.
Some embodiments of the disclosed picture display method are described below in conjunction with fig. 2.

In step S200, the set-top box receives a picture control policy update table sent by the IPTV service platform, where the picture control policy update table includes a mapping relationship between a picture identifier and an updated picture display attribute.
In some embodiments, the picture control policy update table is the second extended JS script, the picture identifier included in the picture control policy table is a picture identifier parameter carried by the second extended JS script, and the picture display attribute is a picture display attribute parameter carried by the second extended JS script.
For example, a policy control module may be constructed on the IPTV service platform side for managing, maintaining, and updating the full-size picture control policy table in real time, and for generating a picture control policy update table. And generating a picture control strategy update table when a user reports that the picture in the EPG page is tampered every time the user reports that the picture in the EPG page is tampered, or an IPTV service system monitors that the picture in the EPG page is actively found to be tampered. Adding a method ImageSetConfig (url, opt) in an extended JavaScript object of the IPTV set-top box, and enabling the set-top box to communicate with a server of the IPTV service by using the extended JavaScript object to obtain a picture control strategy update table. When the picture control strategy table stored in the set-top box needs to be updated, the IPTV service platform issues the picture control strategy update table to the set-top box in real time in the form of the extended JS script.
In step S201, the set-top box replaces the picture display attribute corresponding to the picture identifier in the picture control policy table with the updated picture display attribute corresponding to the picture identifier in the picture control policy update table, so as to update the picture control policy table.
This embodiment is combined with the embodiment corresponding to fig. 1 to provide a complete implementation flow of the image display method of the present disclosure. The IPTV service platform issues a picture control strategy to the set-top box in the form of the extended JS script, and the set-top box analyzes the extended JS script to judge whether the picture is displayed, so that the problem that the IPTV service platform cannot meet the requirement of automatically offline specified pictures under the current IPTV system architecture is solved, the requirement of rapidly and automatically offline illegal pictures in the IPTV service is met, and the safe operation of the IPTV service is ensured. Meanwhile, one side of the set-top box is modified, so that the influence of the existing network IPTV service platform is small, and the implementation is easy.
