specific Embodiment

[0047] Step 201, the server side sets the annotation interface.

[0048] The server sets the annotation interface and provides the annotation interface to the playback terminal, which means that the playback terminal is provided with related functions for video annotation; the playback terminal can submit relevant annotation information through the annotation interface to produce annotations.

[0049] Step 202: When the video playback terminal generates annotation information for the video image during playback and submits it to the server through the annotation interface, the server receives the annotation information and extracts the corresponding video segment according to the annotation information.

[0050] When the user of the playback terminal performs video annotation on a fixed region in a specific video image through the annotation interface, the information corresponding to the image region to be annotated will be obtained, and this part of the information will be us...

Abstract

An embodiment of the invention provides a video annotation method and system. The method includes the steps: a server provides an annotation interface; when a video player terminal plays a video, annotation information is generated according to a video image and submitted to the server through the annotation interface; the server receives the annotation information and extracts a corresponding video segment according to the annotation information; the server judges, in the video segment, whether or not a video annotation having an overlap ratio reaching an overlap threshold with the annotation information exists, combines the annotation information into the video annotation if yes, and generates the video annotation according to the annotation information if not.
