Problems solved by technology

[0005] 3) Due to the relatively large video content traffic and high network bandwidth occupation, the existing video content source consistency comparison technology occupies a high network bandwidth, and if it is not transmitted through a separate network link, it will also affect the playback quality of the video service itself

Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing.

[0023] The video eigenvalue SIFT algorithm process is roughly divided into four steps, and the frame processing process is shown in the appendix figure 1 , briefly described as follows:

[0024] 1) Scale-space extrema detection: Search image locations on all scales. Potential scale- and rotation-invariant interest points are identified by Gaussian differentiation.

[0025] 2) Key point positioning: at each candidate position, the position and scale are determined by a fine-fitting model. Keypoints are chosen according to their stability.

[0026] 3) Direction determination: Based on the local gradient direction of the image, one or more directions are assigned to each key point position. All subsequent operations on the image data are transformed relative to the orientation, scale, and position of the keypoints, thereby providing invariance to these transformations.

Abstract

The invention belongs to the technical field of communication, relates to video source content detection and consistency comparison of IPTV and OTT services, and guarantees the quality and legality ofthe video source service. The invention discloses an IPTV and OTT service-based video content source consistency comparison algorithm and process, and the feature value extraction is an algorithm forconverting audio and video data into video fingerprint features, thereby carrying out the real-time comparison of the consistency of program contents transmitted by a link through the video fingerprint features. A fingerprint feature comparison technology is adopted to reduce the requirement of a transmission network between comparison links, the occupation of bandwidth by returning a target program to a comparison node is avoided, and the comparison efficiency is greatly improved. The method comprises the following steps: S1, a video feature value extraction algorithm; S2, an audio feature value extraction algorithm; S3, a feature value comparison process; and S4, inconsistency and abnormal alarm reporting.

Description

technical field [0001] The invention belongs to the technical field of communication, relates to video source content detection and consistency comparison of IPTV and OTT services, and ensures the quality and legality of video source services. Background technique [0002] With the rapid development of IPTV and OTT services, the user base is getting bigger and bigger, and the market influence is getting bigger and bigger. While developing IPTV and OTT services in an all-round way, operators also need to focus on ensuring the security of video content sources for IPTV and OTT services. The comparison technology of service quality and legality and content source consistency is the video quality and security assurance technology of IPTV and OTT services under this background. The difficulties to be overcome in the consistency comparison of video content sources include: [0003] 1) The volume of video services is large. An IPTV or OTT service platform includes live video servi...
