摘要： Systems and methods of measuring a temporal offset between audio content and video content that employ audio fingerprints from an audio signal in the audio content, and video fingerprints from video frames in the video content. The systems obtain reference audio and video fingerprints prior to transmission of video over a media channel, and obtain target audio and video fingerprints subsequent to transmission of the video over the media channel. Each fingerprint has an associated time stamp. Using the reference and target audio fingerprints and their associated time stamps, the systems determine an audio time stamp offset. Using the reference and target video fingerprints and their associated time stamps, the systems determine a video time stamp offset. Using the audio and video time stamp offsets, the systems determine a temporal offset between the video content and the audio content introduced by the media channel.

摘要： Systems and methods of objective video quality measurement based on support vector machines. The video quality measurement systems can obtain information pertaining to features of a target training video, obtain corresponding information pertaining to features of a reference version of the target training video, and employ the target training features and/or the reference training features to build video quality models using such support vector machines. Based on the target training features and/or the reference training features used to build such video quality models, the video quality models can be made to conform more closely to the human visual system. Moreover, using such video quality models in conjunction with target features of a target video whose perceptual quality is to be measured, and/or reference features of a reference video, the video quality measurement systems can be employed to predict measurements of the perceptual quality of such a target video with increased accuracy.

摘要： Systems and methods of identifying media content, such as video content, that employ fingerprint matching at the level of video frames. The presently disclosed systems and methods of identifying media content can extract one or more fingerprints from a plurality of video frames included in query video content, and, for each of the plurality of video frames from the query video content, perform frame-level fingerprint matching of the extracted fingerprints against fingerprints extracted from video frames included in a plurality of reference video content. Using the results of such frame-level fingerprint matching, the presently disclosed systems and methods of identifying media content can identify the query content in relation to an overall sequence of video frames from at least one of the plurality of reference content, and/or in relation to respective video frames included in a sequence of video frames from the reference content.
