As shown in fig. 2, in the first embodiment of the present application, the video preview method of the present application, when executed by a television end, includes the following steps:
step S210: and when a selection event sent by the remote controller is received, sending a preview request of the video to be previewed to the video processing terminal.
In this embodiment, the selection event is a continuous selection instruction of the video to be previewed generated by the remote controller after the user presses the remote controller for a long time. Specifically, the video processing terminal may be a video server, or may be video processing application software installed on the television terminal.
Case where the video processing side is a video server: when a user browses a video poster in a display interface of a television end, any video poster can be selected through a remote controller, the selected video poster can obtain a focus, after the user presses an 'OK' key of the remote controller for a long time, the television end confirms a video corresponding to the selected video poster as a video to be previewed and sends a previewing request of the video to be previewed to a video server, so that the video server sends video data corresponding to the previewing request to the television end according to the previewing request, and the video data are played for the user through the television end.
The video processing side is the case of the video processing application software installed on the television side: when a user connects a usb disk or an external device to a television and needs to view video files stored in the usb disk or the external device, this embodiment takes the usb disk as an example for description. When a user browses a video list in the U disk at a television end, any video file in the video list can be selected through the remote controller, after the user presses an 'OK' key of the remote controller for a long time, the television end confirms a video corresponding to the selected video file as a video to be previewed, and sends a previewing request of the video to be previewed to the video processing application software, so that the video processing application software obtains video data corresponding to the previewing request from the video list according to the previewing request, sends the video data corresponding to the previewing request to the television end, and plays the video data for the user through the television end.
Step S220: and receiving video data which is sent by the video processing terminal and corresponds to the preview request.
In this embodiment, the video data includes a video resource related to a video to be previewed or an image set associated with the video to be previewed, which is retrieved by the video processing terminal, and the image set includes a plurality of thumbnail images captured from the video to be previewed by the video processing terminal.
Case where the video processing side is a video server: after receiving a preview request sent by a television, the video server acquires video resources related to a video to be previewed or an image set related to the video to be previewed from a database according to the preview request, and sends the video resources or the image set corresponding to the preview request to the television. The video resource and the image set are uploaded to a database of a video server by an operator in a background, a video poster in a display interface of a television end is associated with the video resource or the image set in the database of the video server, and the video server acquires video data from the database according to a preview request, and sends the acquired video resource to the television end; and the frequency server sends the acquired image set to the television terminal if the video data acquired from the database according to the preview request is the image set.
The video processing side is the case of the video processing application software installed on the television side: the video processing application software acquires a video file corresponding to the preview request from the video list according to the preview request, intercepts videos in any time period from the acquired video file to obtain short videos in corresponding time periods, splits the short videos to form a plurality of thumbnail pictures, arranges the thumbnail pictures according to the time sequence to form an image set, and then sends the image set to the television.
Step S230: and previewing the video to be previewed according to the video data.
And when the television end receives the video resource or image set sent by the video processing end, reading the video resource or image set, thereby realizing the playing of the video resource or image set, and achieving the purpose that a user previews the video corresponding to the video poster or the purpose that the user previews the video corresponding to the video file in one of the U disk and the external equipment.
According to the technical scheme, the technical means that when the selection event sent by the remote controller is received, the preview request of the video to be previewed is sent to the video processing terminal, the video data corresponding to the preview request sent by the video processing terminal is received, and the video to be previewed is previewed according to the video data are adopted, so that the efficiency of browsing the video content of the television homepage movie of the user is improved, and the experience of browsing the video content of the television homepage movie of the user is improved.
