A method of generating a moving thumbnail is disclosed. The method includes sampling video frames of a video item. The method further includes determining frame-level quality scores for the sampled video frames. The method also includes determining multiple group-level quality scores for multiple groups of the sampled video frames using the frame-level quality scores of the sampled video frames. The method further includes selecting one of the groups of the sampled video frames based on the multiple group-level quality scores. The method includes creating a moving thumbnail using a subset of the video frames that have timestamps within a range from the start timestamp to the end timestamp.

A method for receiving a real-time video feed of a region of interest includes generating, at a processor of a first device, a request for a real-time video stream of the region of interest. The request indicates a location of the region of interest. The method also includes transmitting the request to one or more other devices via a network to query whether another device is situated to capture a portion of the region of interest. The method also includes receiving the real-time video stream of the region of interest from a second device of the one or more other devices. The second device includes a camera having a field of view that includes at least a portion of the region of interest.

A system and methods for generating automated real-time live video stream of a target that is moving around an obstacle of pre-defined area uses an automated video streaming provided with a plurality of video cameras that are positioned about the pre-defined area by tracking the moving target and displaying the moving target on the animated timeline such as current class leader will be automatically displayed and compared, in real time, with the rider on the track and integrating the data collected by the wireless network to make video stream from that camera to the optimized video stream.

Systems and methods for stitching advertisements in streaming content are disclosed. In some embodiments, a method comprises receiving one or more advertisements. An unmarked content item may be received, the unmarked content item comprising a stream-enabled video including a set of sequential black frames. An insertion point may be identified based on a location of at least one black frame of the set of sequential black frames without requiring user input, the insertion point identified during streaming of the unmarked content item to a consumer system, the insertion point being ahead of a current playback point of the unmarked content item streaming to the consumer system. The one or more advertisements may be stitched in the unmarked content item at the insertion point. The unmarked content item may be streamed to a consumer system until the insertion point is reached, and the one or more advertisements may be streamed to the consumer system when the insertion point is reached.

The playback of video content upon a display is enhanced through the unobtrusive presentation of extrinsic data upon the same display. A video content feature is rendered on a display. A quantity of extrinsic data relevant to a current time in the video content feature is determined based at least in part on viewing history of a user. A graphical element presenting at least a portion of the extrinsic data is rendered on the display while the video content feature is also being rendered on the display.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for generating search queries in response to obtaining audio samples on a client device. In one aspect, a method includes the actions of i) receiving audio data from a client device, ii) identifying specific content from captured media based on the received audio data, wherein the identified specific content is associated with the received audio data and the captured media includes at least one of audio media or audio-video media, iii) obtaining additional metadata associated with the identified content, iv) generating a search query based at least in part on the obtained additional metadata, and v) returning one or more search results to the client device, the one or more search results responsive to the search query and associated with the received audio data.

Aspects of the subject disclosure may include, for example, facilitating access to a synopsis of a missed portion of a media program, identifying subject matter in a segment of content in the media program that has not been presented, determining a particular time for presenting the summary according to the subject matter in the segment of content, and initiating a presentation of the summary at the particular time. Other embodiments are disclosed.

Techniques and systems are provided for identifying a video segment displayed on a screen of a remote television system, and providing an option to switch to an alternative or related version of the video program that includes the video segment. For example, video segments displayed on a screen of a television system can be identified, and contextually-targeted content or contextually-related alternative content can be provided to a television system based on the identification of a video segment. The alternative or related version of the video program can include the currently displayed program in an on-demand format that can be viewed off-line and can be started over from a beginning portion of the program.

In one embodiment of the present invention, a native resolution analyzer generates a log-magnitude spectrum that elucidates sampling operations that have been performed on a scene. In operation, the native resolution analyzer performs a transform operation of a color component associated with a frame included in the scene to generate a frame spectrum. The native resolution analyzer then normalizes the magnitudes associated with the frame spectrum and logarithmically scales the normalized magnitudes to create a log-magnitude frame spectrum. This two dimensional log-magnitude frame spectrum serves as a frequency signature for the frame. More specifically, patterns in the log-magnitude spectrum reflect re-sampling operations, such as a down-sampling and subsequent up-sampling, that may have been performed on the frame. By analyzing the log-magnitude spectrum, discrepancies between the display resolution of the scene and the lowest resolution with which the scene has been processed may be detected in an automated fashion.

One embodiment of the present invention sets forth a technique for detecting a shot change in a video. The technique includes calculating a first plurality of difference values for pixel blocks included in a first video frame and a second video frame and calculating a first cumulative distribution function (CDF) based on the first plurality of difference values. The technique further includes calculating a second plurality of difference values for pixel blocks included in a first plurality of video frames that is contiguous with the first video frame and calculating a second CDF based on the second plurality of difference values. The technique further includes comparing the first CDF to the second CDF to detect a shot change.
