Embodiment 1

[0052] Such as figure 1 As shown, Embodiment 1 of the present invention provides a broadcast video clip acquisition method, which is characterized in that it includes the following steps:

[0053] S1: The broadcast information source 1 intercepts at least one material image from the video, adds tags to the material image, generates a tag set for all tags, and sends it to the server 2;

[0054] The material image can be an image of a contoured entity such as a person, an object, a building, etc., and should have a clear boundary with the background and be easily distinguished;

[0055] S2: The user terminal 3 acquires the tag set from the server 2, selects at least one tag from it, and sends a video acquisition request to the server 2;

[0056] S3: The server 2 receives the video acquisition request sent by the user terminal 3, and searches for at least one target video according to the tag;

[0057]The tags selected by the user represent their personalized requirements for v...

Embodiment 2

[0064] Such as figure 2 As shown, this embodiment 2 provides a broadcast video clip acquisition method on the basis of embodiment 1, and this embodiment 2 further defines that the step S1 includes the following steps:

[0065] S1.1: Broadcast information source 1 browses the video content, and counts the materials appearing in the video according to the characteristics of the material;

[0066] Since the same material often appears in different angles and different states in the video, simply performing mechanical statistics based on the overall material is often not accurate enough, and the probability of omission is high. Therefore, it is necessary to select at least one feature on the material for statistics; for example , if the material is a person, it can be distinguished from other materials by the person’s facial features, clothing, accessories, digital signs, etc.; if the material is a building, it can be distinguished by the outline of the building, the decoration o...

Embodiment 3

[0071] Such as image 3 As shown, this embodiment 3 provides a broadcast video clip acquisition method on the basis of embodiment 1, and this embodiment 3 further defines that the step S4 includes the following steps:

[0072] S4.1: According to the material image corresponding to the label, search for an image matching each of the material images from the target video;

[0073] Since at least two different images are provided for each material, the available resources during matching can be increased, the matching range can be expanded during matching, the accuracy and comprehensiveness of matching can be improved, and omissions can be avoided;

[0074] S4.2: Obtain all frames containing the image, and record the time stamp corresponding to each frame.

[0075] Such as Figure 4 As shown, the step S5 includes the following steps:

[0076] S5.1: Generate a time threshold, and intercept corresponding frames in the target video according to the timestamp; the lower limit of t...

Abstract

The invention provides a method and a system for obtaining broadcast video clips. According to tags in a video obtaining request sent by a user terminal, corresponding videos are selected, and the video clips having corresponding materials are obtained from therein; the matching is performed by taking frames as a unit, so the accuracy and the completeness of the matching can be improved; the judgment is performed on timestamps of the frames by taking a time threshold as a standard to determine optimal positions of the clips, and video fragments are intercepted according to the corresponding timestamps, so that the effective information can be collected to the utmost extent, the ineffective information is removed, and simultaneously the smoothness of pictures can be guaranteed. According to the method and the system for obtaining the broadcast video clips provided by the invention, a personalized video file can be customized for a user, and the best watching experience is provided for the user.

Description

technical field [0001] The invention belongs to the technical field of personalized broadcasting, and in particular relates to a method and system for acquiring broadcast video clips. Background technique [0002] Broadcast (broadcast) originally refers to a news dissemination tool that transmits sound through radio waves or wires. It is called wireless broadcasting that transmits programs through radio waves, and cable broadcasting that transmits programs through wires. Today, broadcasting in a broad sense also includes network broadcasting. Internet broadcasting is a kind of network streaming media. By establishing a broadcast server on an Internet site, running specific software and then disseminating the program, users can easily listen to the broadcast by installing and running broadcast receiving software on their own computers to connect to these sites. program, read broadcast information. [0003] In today's fast-changing broadband network technology, Internet broa...
