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.

Methods, systems, and media for generating an advertisement from a video stream are provided. In accordance with some embodiments, the method comprises: receiving, from a first user device, advertisement parameters associated with an advertisement campaign for placing an advertisement based on the advertisement parameters, wherein the advertisement parameters include one or more keywords; associating the advertisement parameters with an identifier of the first user device; receiving, from the first user device, a live video stream; receiving, from a second user device, a request to present an advertisement; identifying the live video stream based at least in part on the one or more keywords; generating the advertisement using the live video stream and the advertisement parameters; and causing the advertisement to be presented on the second user device as the advertisement.

Systems and methods are disclosed herein for avoiding playback of an advertisement by selectively switching between media streams. To this end, a media guidance application receives a plurality of media streams from different sources, switches to a first media stream and plays back a first media asset of the first media stream, and determines that an end to playback of the first media asset is imminent. The media guidance application then determines whether a second media stream of the plurality of media streams is within a threshold amount of time of playing back a beginning of a second media asset, and if the second media stream is within the threshold amount of time of playing back the beginning of the second media asset, the media guidance application switches from the first media stream to the second media stream and plays back the second media asset.

Techniques described herein provide for a live advertising processing engine service to act as an intermediary between client applications and advertising networks. The live advertising processing engine service can provide an interface with which the client can interact, via an application programming interface (API) or directly through the use of a standardized language, thereby allowing client applications to receive advertisement data without the need to be customized to communicate with specific advertising networks. The live advertising processing engine service can further track where, in playback the live content, a client currently is, to indicate to the client—or other application—when advertisement breaks are and/or provide supplemental advertisement information to enable the client to provide a rich user experience.

In one aspect, a method includes: (i) determining a baseline input-to-output delay, which represents a time period between when content is input into a first input buffer and output by an output buffer; (ii) establishing a synchronous lock between (a) first fingerprint data representing content in the first input buffer and (b) second fingerprint data representing content in the output buffer; (iii) determining an instruction time-point at which a content-presentation device is instructed to switch from using content in the first input buffer to populate the output buffer, to using content in the second input buffer to populate the output buffer; (iv) determining a loss of synchronous lock time-point; (v) using the determined baseline input-to-output delay, the determined instruction time-point, and the determined loss of synchronous lock time-point to determine an input-buffer switching delay; and (vi) using the determined input-buffer switching delay to facilitate performing a content-modification operation.

Disclosed are a video generation method and apparatus, an electronic device, and a computer readable medium. A specific embodiment of the method comprises: obtaining a video footage and an audio footage, the video footage comprising a picture footage; determining a music point of the audio footage, the music point being used for dividing the audio footage into a plurality of audio clips; using the video footage to generate a video clip for each music clip in the audio footage to obtain a plurality of video clips, corresponding music clips and video clips having the same duration; and splicing the plurality of video clips according to the time when music clips respectively corresponding to the plurality of video clips appear in the audio footage, and adding the audio footage as a video audio signal to obtain a composite video.

An orientation based, aspect-ratio switching video playback system selects from multiple video streams having corresponding content to automatically match the orientation of the device and play a version of the video filmed, produced and formatted for that orientation. Orientation changes may occur at any time during playback. When an orientation change is detected, the video playback system stores the current playback time, switches to the video stream optimized for the new orientation, and resumes playback from the stored playback time. Switching may be performed automatically and seamlessly to enable the viewer to continue watching the video in the new orientation, at the optimal aspect ratio for such orientation, using the full screen area without clipping any video content, and without interruption.

Systems and methods are described to detect a location to place an advertisement in a media asset, the method comprising, identifying a plurality of points in a video frame of a media asset, detecting a color associated with each point of the plurality of points, calculating a change in color between each point of the plurality of points, comparing the change in color between each point of the plurality of points with a threshold, identifying, based on the comparing, an area within the frame that constitutes a surface; and selecting an advertisement to be placed on the surface.

This application discloses a video source switching method, a playing method, an apparatus, a device, and a storage medium. The video source switching method includes obtaining switching information; determining a first key frame of a first video source according to the switching information, the first key frame being a next key frame of a current playing time of the first video source; querying a first time value of the first key frame; identifying a second video source according to the switching information; and switching video sources if a distance between a current time value of the second video source and the first time value is less than or equal to a threshold.

An information processing apparatus includes circuitry configured to receive a manifest file for a content stream, the manifest file including a manifest file update mechanism indicating one or more ways of receiving an update to the received manifest file. The circuitry is also configured to receive a manifest file update through the manifest file update mechanism indicated by the received manifest file. The manifest file update indicates that early termination of content during a period in the content stream is possible. The circuitry is also configured to send a request for the content associated with the period to a server based on the manifest file update, and receive the content from the server. The circuitry is also configured to output the content for display during the period and terminate the content early based on the manifest file update.
