Embodiment 1

[0028] like figure 1 As shown, this embodiment provides a multi-terminal synchronous display method, which includes:

[0029] 101. The display terminal obtains the first texture picture, the playing time point of the first texture picture, and the second texture picture and the playing time point of the second texture picture, and the playing time point of the second texture picture is at the After the playback time point of the first texture picture.

[0030] 102. Before the playing time point of the first texture picture, the display terminal loads the obtained first texture picture into a video memory of the display terminal.

[0031] 103. Before the playback time point of the second texture picture, after loading the first texture picture, and when the graphics processor GPU of the display terminal has free resources, the display terminal will obtain the second texture picture The second texture picture is loaded into the video memory of the display terminal.

Embodiment 2

[0034] like figure 2 As shown, this embodiment provides a multi-terminal synchronous display method, which includes:

[0035] 201. The display terminal obtains the first texture picture, the playing time point of the first texture picture, and the second texture picture and the playing time point of the second texture picture, and the playing time point of the second texture picture is at the After the playback time point of the first texture picture.

[0036] 202. If the interval between the playing time point of the first texture picture and the current time point is less than the preset loading time, the display terminal will obtain the first texture picture before the playing time point of the first texture picture. The texture picture is loaded into the video memory of the display terminal.

[0037] 203. If the interval between the playing time point of the second texture picture and the current time point is longer than the preset loading time, the display terminal is...

Embodiment 4

[0048] like Figure 4 As shown, this embodiment provides another display terminal, which includes an acquiring unit 401 and a processing unit 402 . The acquiring unit 401 is configured to acquire the first texture picture, the playing time point of the first texture picture, the second texture picture and the playing time point of the second texture picture, and the playing time point of the second texture picture is at the After the playback time point of the first texture picture, and transmit the first texture picture, the playback time point of the first texture picture, the second texture picture and the playback time point of the second texture picture to A processing unit 402; the processing unit 402 is configured to receive the first texture picture, the playing time point of the first texture picture, the second texture picture and the playing of the second texture picture transmitted by the acquiring unit 401 time point, before the playing time point of the first te...

Abstract

The embodiment of the invention discloses a multi-terminal synchronous display method. The multi-terminal synchronous display method comprises the following steps: a display terminal acquires a first texture picture and a playing time point of the first texture picture as well as a second texture picture and a playing time point of the second texture picture, wherein the playing time point of the second texture picture is behind the playing time point of the first texture picture; before the playing time point of the first texture picture, the display terminal loads the obtained first texture picture to a video memory of the display terminal; and before the playing time point of the second texture picture, after the loading of the first texture picture and when a graphic processing unit (GPU) at the display terminal has idle resources, the display terminal loads the acquired second texture picture to the video memory of the display terminal. The invention also provides a corresponding display terminal and display system. According to the embodiment of the invention, the problems of influent subtitle playing, CPU (Central Processing Unit) suspended animation and subtitle reporting lock caused by loading more subtitle textures are solved.

Description

technical field [0001] The invention relates to a method for loading texture pictures, a display terminal, a server and a system. Background technique [0002] In the existing subtitle broadcasting system, when the display terminal lacks fonts, the server renders the subtitles of the target font library into a picture format and compresses them, and then sends the compressed subtitle picture to the display terminal for display. Due to the long length of the subtitle, the subtitle picture is generally a divided picture. [0003] After receiving the compressed subtitle picture, the display end converts the compressed image data into pixel information, and loads the subtitle texture. There are two ways to load the subtitle texture: one is to load the subtitle texture at one time before the subtitle is played; the other is to load the subtitle texture successively when the subtitle is played. The former will cause delays in subtitle playback, reducing the real-time performance...
