Embodiment 1

[0028] Embodiment 1 of the present invention provides a method for capturing TV content across screens based on voiceprint recognition. figure 1 As shown, the method includes the following steps:

[0029] S1: Steps of transcoding and storing into the library Cloud server with voiceprint SDK installed 1 Monitoring channel source satellite live channel source signal reception and collection 5 (live) or on-demand program upload 6 (on-demand)

[0030] The audio and video streams of the cloud server 1 TV media server 2 and voiceprint server 3 are stored in 7, and transcoded (converted to a stream that can be recognized by the network TV server and can be transmitted on the Internet) to form TV media data Library 4, to obtain transcoded audio and video streams into the library; the channel source includes audio and video streams from IPTV, digital TV or analog TV, the audio and video streams can also be transcoded (for example, the wireless signal from the satellite is converted into IPT...

Embodiment 2

[0042] Embodiment 2 is a method for capturing TV content across screens based on voiceprint recognition provided on the basis of Embodiment 1. The multiple-length recording segments include m-length recording segments of T duration, and the m-th segment is greater than the m-th segment. Duration of 1 recording segment, T m > T m-1 . When m=3, T1 is 3s, T2 is 5s, and T3 is 15s.

Embodiment 3

[0044] Embodiment 3 is a method for capturing TV content across screens based on voiceprint recognition provided on the basis of Embodiment 2, and the matching is sequential matching of m recording segments. That is, m1, m2, and m3 are matched in sequence until the match is successful. If it is still matched, it is necessary to obtain multiple time-length recording clips again for matching.

Abstract

The invention provides a cross-screen television content capturing method based on voiceprint recognition. The method comprises the following steps: S1, carrying out transcoding and warehousing; s2, performing audio separation; s3, extracting voiceprints and establishing a voiceprint library; s4, extracting a recording fragment voiceprint; s5, carrying out recording fragment voiceprint matching; s6, pushing an identification result; s7, intercepting a short video; and S8, editing and publishing the short video. The method breaks through the limitation of a transmission physical network, is unlimited in service application range, and can be applied to all television transmission fields of analog televisions, cable televisions, digital televisions, IPTVs and the like. The method can extractthe voiceprint in the video, but the voiceprint cannot be restored into the video, so that the data transmission has no leakage risk, and the security is high.

Description

Technical field [0001] The invention belongs to the field of television content interception, and particularly relates to a method for cross-screen television content interception based on voiceprint recognition. Background technique [0002] With the development of the economy, there are more and more multimedia organizations. These organizations can generate countless movies, TV series, documentaries, variety shows and other long video programs every day. Due to restrictions on copyright and other reasons, many wonderful content can only be watched by certain audiences in specific channels. For example, a popular drama first broadcasted on a live channel on the TV side, mobile terminal users cannot download, watch, forward, etc., and users watch The status of the content is static and single; and because there are more and more long video resources now, most users do not have enough time to watch the long video, they will watch the long video through fast forward and other mean...
