Methods and apparatus for monitoring locally inserted media are disclosed. A disclosed apparatus includes instructions to detect, at a media device at an end user location, a frequency of a watermark that was spliced into a primary media stream received at the media device after the primary media stream was received at the end user location, associate identifying tags with segments of the primary media stream that were spliced, in response to the detection of the watermark, determine an advertisement associated with the segments of the primary media based on the identifying tags, present the primary media at a first time and the advertisement at second times, record a log including first identifying information including an identity of the content of the primary media and second identifying information including a change in the frequency of the watermark corresponding to the advertisement; and transmit the log to a data collection facility.

A method for reducing the number of images or the length of a video from a digital image collection using a social network, includes receiving a digital image collection captured by a user to be viewed by a viewer; wherein the viewer and the user are members of the same social network and using a processor to access the social network to determine a relationship between a viewer and the user. The method further includes using the processor to determine a set of summarization parameters based on the relationship between the viewer and the user and using the processor to reduce the number of images or the length of the video from the digital image collection using the determined set of summarization parameters to be viewed by the viewer.

Methods and apparatus to detect blank images in a digital video broadcast signal are disclosed. An example method of detecting a blank image includes receiving a compressed digital image including a plurality of DC values, analyzing a total number of bits in the digital image to determine if the digital image has a data size small enough to be a blank frame candidate, if the data size is small enough for the digital image to be a blank frame candidate, analyzing multiple areas of the digital image to determine if the multiple areas exhibit substantially a same complexity, if the multiple areas exhibit substantially the same complexity, determining a number of DC values in the plurality of DC values that meet a criterion, comparing the determined number of DC values meeting the criterion to a threshold, and identifying the received digital image as a blank image if the determined number of DC values exceeds the threshold.

The disclosure can provide a method for shooting a video. The method includes: obtaining a target music file for shooting the video and a preset shooting duration; obtaining shooting guidance information based on beat information of the target music file and the preset shooting duration; the shooting guidance information including a number of clips of the video within the preset shooting duration and a clip duration of each of the clips; and displaying the shooting guidance information in a shooting interface.

Example embodiments provide systems and methods for rewinding digital content during playback based on context of the digital content. A content rewind system electronically accesses digital content. A rewind trigger is detected by the system. The system analyzes the digital content to detect at least one dialog segment within the digital content. The analysis is based on context of the digital content (e.g., dialog within the digital content). The system rewinds playback of the digital content by rewinding to a starting point of a previous dialog segment.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for generating videos. In one aspect, a method comprises: receiving: (i) an input video comprising a sequence of video frames, and (ii) data indicating a target object type; processing the input video to generate tracking data that identifies and tracks visual locations of one or more instances of target objects of the target object type in the input video; generating a plurality of sub-videos based on the input video and the tracking data, including: for each sub-video, generating a respective sequence of sub-video frames that are each extracted from a respective video frame of the input video to include a respective instance of a given target object from among the identified target objects of the target object type; and generating an output video that comprises the plurality of sub-videos.

A video quality estimation device for estimating quality to be experienced by a user during viewing of a video includes a video quality estimation unit that calculates a video quality estimation value based on a parameter related to video quality of a high image quality region in the video, a parameter related to video quality of a low image quality region in the video, and a parameter related to a time for switching from a low image quality display state to a high image quality display state.

In various examples, recordings of gameplay sessions are enhanced by the application of special effects to relatively high(er) and/or low(er) interest durations of the gameplay sessions. Durations of relatively high(er) or low(er) predicted interest in a gameplay session are identified, for instance, based upon level of activity engaged in by a gamer during a particular gameplay session duration. Once identified, different variations of video characteristic(s) are applied to at least a portion of the identified durations for implementation during playback. The recordings may be generated and/or played back in real-time with a live gameplay session, or after completion of the gameplay session. Further, video data of the recordings themselves may be modified to include the special effects and/or indications of the durations and/or variations may be included in metadata and used for playback.
