Embodiment 1

[0062] Embodiments of the present invention provide a video retrieval method, such as figure 1 shown, including:

[0063] S101. A video device obtains a first video set.

[0064] Wherein, the first video collection includes at least two videos.

[0065] Specifically, the video device may search according to the search words input by the user to obtain the first video collection; or may perform a relevance search according to the video currently selected by the user to obtain the first video collection; or may also search according to the user's The speech input information is retrieved to obtain the first video collection.

[0066] Exemplarily, the video device may determine the user's input keyword according to the user's search information (including the search term input by the user, the search term corresponding to the video currently selected by the user, or the user's voice input information), and Retrieval is performed to determine the first video collection. Wherei...

Embodiment 2

[0077] Embodiments of the present invention provide a video retrieval method, such as figure 2 shown, including:

[0078] S201. The video device obtains a first video collection.

[0079] Specifically, S201 may be any one of S201a, S201b or S201c.

[0080] S201a. The video device searches according to the search term input by the user, so as to obtain the first video collection.

[0081] S201b. The video device performs relevancy search according to the video currently selected by the user, so as to obtain the first video set.

[0082] S201c. The video device searches according to the voice input information of the user, so as to obtain the first video collection.

[0083] Exemplarily, in the embodiment of the present invention, the video device is provided with a search box, and the video device can receive the user's search information through the search box, and then perform search according to the user's search information to determine the first video collection.

Abstract

The embodiment of the invention discloses a video retrieval method and a video device, and relates to the technical field of electronic information. A video can be rapidly retrieved, and the video retrieval efficiency can be improved. According to the specific scheme, the video retrieval method includes the steps of obtaining a first video set; calculating information entropies of at least two attributive classifications in the first video set, wherein each attributive classification comprises at least two sub-classifications; reminding a user to carry out selection in the sub-classifications of the attributive classification with the largest information entropy. The video retrieval method and the video device are used in the video retrieval process.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a video retrieval method and a video device. Background technique [0002] With the development of multimedia technology, many multimedia webpages, multimedia applications and clients that can provide users with a video retrieval function have emerged in the field of multimedia technology. [0003] In the prior art, multimedia webpages, multimedia applications, and video devices in the client generally display the videos in each attribute category for the user in a fixed order on the retrieval interface for the user to choose, and then receive the user's request and list them on the retrieval interface. The selection of the attribute category above displays the subcategories of the attribute category on the search interface for the user, and then receives the user's selection of the subcategory of the attribute category, and retrieves all videos contained in the su...
