Embodiment Construction

[0047] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0048] Such as figure 1 As shown, the embodiment of the present invention provides a data projection method, which is suitable to be deployed on a user-side terminal, such as a PC or a notebook computer, and is preferably deployed on a set-top box. The method includes the following steps:

[0049] 101. When playing a video of low-dimensional image data on the terminal, a pause signal is received;

[0050] The above-mentioned low-dimensional image data in this embodiment is relative to high-dimensional image data, that is, those with lower image quality than high-dimensional image data can be considered as low-dimensional image data in this embodiment, such as low-d...

Abstract

The invention discloses a data projection method, device and system, and relates to the technical field of multimedia information. The data projection method mainly comprises the steps that when a low dimension image data video is played on a terminal, a pause signal is received; the video playing time point during pause is recorded under the triggering of the pause signal; the time point and the identification of the video are sent to the network side.

Description

technical field [0001] The present invention relates to the technical field of multimedia information, in particular to a data projection method, device and system. Background technique [0002] At present, when users use a projector, they mostly connect it to a computer, and then project data on the computer to a screen for display through the projector. This method is more practical for displaying only PPT and other types of data files. However, if media files such as movies and videos are projected, since the media files on the computer are basically 2D data, that is, 2-dimensional media data, it is easy to appear unclear display or reduce the quality of the video image by zooming in after projection. image quality issues. [0003] Although it is also possible to store high-definition video media files or 3D video files on the computer for playback, as everyone knows, 3D video files have a large amount of information and take up disk space. Inferior, it is not suitable...
