Abstract: Embodiments provide for outputting video and allowing a user to switch between different audio streams in a synchronous manner without impacting the timeline of the audio presentation. The audio and video streams may be directed to a single sporting event. For example, a user can view video associated with a national television broadcast of a baseball game, and switch between the audio from the national broadcast and the audio from the radio broadcast. Similarly, the user can view video associated with a local television broadcast, and switch between the audio from the national, regional, and/or radio broadcast. As any sport fan would appreciate, such flexibility enables users to watch the video with, e.g., the best quality and camera angle, while at the same time listening to the audio or broadcaster they find the most appealing.

Abstract translation: 实施例提供了输出视频并允许用户以不同音频流同步的方式进行切换而不影响音频呈现的时间线。 音频和视频流可以被引导到单个体育赛事。 例如，用户可以观看与国家电视广播棒球游戏相关联的视频，并且在国家广播的音频和来自无线电广播的音频之间进行切换。 类似地，用户可以观看与本地电视广播相关联的视频，并且在国家，地区和/或无线电广播的音频之间切换。 正如任何运动爱好者所理解的，这样的灵活性使得用户能够以例如最佳质量和相机角度观看视频，同时收听他们发现最有吸引力的音频或广播者。

Abstract: An end user can sample a radio or television broadcast, generate a user representation of the broadcast sample, and send the user representation to a comparison system, which also receives known representations of content broadcast by multiple different stations. The known representations are stored in a continuous fashion, and represent actually broadcast content. The comparison system identifies the source of the broadcast sample by comparing the user representation to the known representations associated with each of the different stations. By comparing two representations of content that was actually broadcast, a broadcast source can be identified without requiring the use of watermarks, timestamps, or a database of discreet content items.

Abstract: A system for identifying motion video/audio content by means of comparing a video A to a registered video B so as to determine if they are originally the same as each other, wherein said system at least comprises a fingerprint extractor A for fingerprint A from the video A; a fingerprint database for the registered video B; and a matcher which is adapted to search from the fingerprint database for the registered fingerprint B of the video B by means of comparison of fingerprint A with a shifting window of a possible fingerprint B, so as to determine that the video A is visually identical to the video B if a match is found. According to the present invention, the method for extracting a fingerprint data from video/audio signals facilitates the automatic identification, archiving and search of video content, and can be of archiving without the need for human visual inspections.
