- Text track objects are objects that can be created, deleted, and manipulated.
- a new text track object can include information such as start time and end time.
- the text track object can be operated by a predetermined program, the text track object can be realized as a scroll display effect.
- Step 306 For each text track object, the text track object is controlled by a preset program to display a display position corresponding to the appearance time on the online video according to the appearance time, and the display style of the text track object corresponds to the display style information.
- the preset program is a Java program carried in a webpage conforming to the HTML5 protocol.
- the Java program can control each text track object to be displayed on the online video according to the respective appearance time, and the appearance position on the online video is the display position corresponding to the appearance time.
- the display style of each text track object corresponds to the corresponding display style information, that is, the font size, the font type, and the like correspond to the corresponding display style information.
- Step 307 changing the display position of the text track object every predetermined time interval by a preset program.
- the Java program For each text track object, the Java program also changes the display position of the text track object every predetermined time interval.
- the predetermined time interval may be a predetermined time interval; or may be a time interval indicated in the display time information.
- the Java program moves the text track object to the right side by a predetermined length every 0.2 seconds.
- Step 308 the text track object is controlled to disappear on the online video according to the end time by a preset program.
- the Java program For each text track object, the Java program also controls the text track object to disappear on the online video at the end time.
