Embodiment 1

[0068] The embodiment of the present invention proposes a method for splitting news video items, such as figure 1 and figure 2 As shown, the method includes presetting a news program template library, and performing the following steps:

[0069] Step 201: Decode an audio signal from a broadcast television signal, and extract audio fingerprint features from the audio signal.

[0070] Step 202: Match the audio fingerprint feature extracted from the broadcast TV signal with the template in the news program template library, determine the broadcast time of the news program in the broadcast TV signal, and obtain the news program video according to the broadcast time

[0071] Step 203: For the obtained news program video, split the news program video into independent news items by means of the human-computer interaction interface and the method of combining manual operation and computer intelligent audio-video algorithm.

[0072] It can be seen that in the embodiment of the prese...

Embodiment 2

[0083] The implementation process of a preferred embodiment of the present invention will be described in more detail below through a specific example. The method includes setting a news program template library in advance, and performing the following steps, wherein the template library stores audio fingerprint features extracted from manually collected program clips after being decoded into audio signals by a decoder.

[0084] Step 301: Collect broadcast television signals.

[0085] In this step, the broadcast TV signals include analog, satellite (DVB-S), CTV, DBS, digital (DVB-C), terrestrial digital multimedia broadcasting (TDMB) and other broadcast TV signals.

[0086] Step 302: Transcode the broadcast TV signal into a digital file and store it in a large-capacity storage device or transmit it to a subsequent processing system in the form of audio and video streams.

[0087] In this step, the digitized files or audio and video streams exist in various common audio and vi...

Embodiment 3

[0109] Another embodiment of the present invention also proposes a news video item splitting system, see Figure 5 The system includes:

[0110] News program template library module 501, audio and video decoding module 502, news video positioning module 503 and news video entry splitting module 504, wherein,

[0111] The news program template library module 501 is used to store the news program template library;

[0112] The audio and video decoding module 502 is used to decode the audio signal from the broadcast television signal, extract the audio fingerprint feature for the audio signal, and send the audio fingerprint feature to the news video location module 503;

[0113] News video positioning module 503 is used to match the templates in the news program template library in the audio fingerprint feature received with the news program template library module, determine the broadcast time of news programs in the broadcast television signal, according to the broadcast time ...

Abstract

The invention provides a method and a system for splitting a news video entry. The method comprises the following steps: decoding an audio signal from a radio and television signal; extracting audio fingerprint characteristic of the audio signal; matching with a template in a news program template library; determining the broadcast time of a news program in the radio and television signal; obtaining news program video according to the broadcast time; splitting the news program video into independent news entries by means of a human-computer interaction interface and through using a manual operation and computer intelligent audio and video algorithm combined method. The method and the system can guarantee the splitting of the news programs.

Description

technical field [0001] The invention belongs to the technical field of network communication, and in particular relates to a method and system for splitting news video items. Background technique [0002] Radio and television is a medium for disseminating information to users, and it is an important part of people's life, leisure, entertainment, information and social life. Among them, TV news has become an important channel for news dissemination due to its rich content, vivid images, and rapid dissemination. [0003] With the advancement of network technology and the continuous advancement of "triple play", TV news has also received great attention on the Internet.
