摘要： Aspects of the subject disclosure may include, for example, receiving, for a selected channel, a first video; processing the first video for rendering on a display being viewed by a user; selecting from among a plurality of channels a subset of channels for which to pre-fetch data, the selecting being according to predictions that each channel of the subset of channels is more likely to be requested by the user than each channel of the plurality of channels that is not part of the subset; prioritizing the subset of channels such that a first channel of the subset of channels has a priority over a second channel of the subset of channels, the first channel being given the priority based upon a prediction that the first channel is more likely to be requested by the user than the second channel; pre-fetching, for the first channel, first data of a first type and second data of a second type; and pre-fetching, for the second channel, third data of the first type without pre-fetching any data of the second type. Other embodiments are disclosed.

摘要： A method for generating video from scratch, including retrieving template video, reading commands of predefined programming language, wherein commands include instruction corresponding to video action and time line at predefined layer of media/video element (properties) and new parameters including information from external data sources. The video action includes at least one of: drawing action, object selection, change of object properties, creating text, motion action relating at least one object, background creation, defining layer of video, animation of the object itself. The method includes generating video layers by applying the relevant actions based on commands instruction, scheduling timing and layer definitions. The actions include changing object properties drawing action, object selection, change of object properties, creating text, motion action relating at least one object, background creation, defining layer of video, animation of the object itself. The method also includes integrating video template with generated video layers, and rendering the frames to generate a video.

摘要： Systems and methods are described to dynamically generate metadata for a live media stream. The system determines that a first user on a social media network has started a live media stream. In response, the system identifies a topic of the live media stream based on a frame of the live media stream and identifies another person featured in the frame of the live media stream based on social connections of the first user in the social media network. The system then generates a title for the live media stream based on the identified topic and the identified person, and transmits a notification to a second user that the first user is streaming live, where the notification includes the generated title.

摘要： This document describes marker based approaches for a CDN to monitor and report on the amount of traffic that it is serving on behalf of content providers. They are particularly useful in hybrid delivery scenarios. Hybrid delivery scenarios means that a client may obtain content, such as a given multimedia stream, from one or more servers in the CDN, or from one or more peers in a peer to peer network. The amount of data served from the peer network is referred to herein as the “offload”, as delivery of that data has been offloaded from the CDN platform.

摘要： A method and system for enhancement of video systems using wireless device proximity detection. The enhanced video system consists of one or more video capture devices along with one or more sensors detecting the presence of devices with some form of wireless communications enabled. The proximity of a device communicating wirelessly is sensed and cross referenced with received video image information. Through time, movement of wirelessly communicating mobile devices through a venue or set of venues can be deduced and additionally cross referenced to and augmented over image data from the set of video capture devices.

摘要： In a communication system where a channel feed carrying a media stream is broadcast for delivery of the media stream to a media client, where the channel feed further includes metadata in-band and correlated with a content frame of the media stream, but where the metadata gets removed from the channel feed before the media stream reaches the media client, a computing system (i) extracts the metadata from the channel feed and (ii) transmits out-of-band to the media client the extracted metadata in correlation with reference fingerprint data representing the frame of the media stream, the correlation being useable by the media client as a basis to re-correlate the metadata with the frame of the media stream, so as to enable the media client to carry out an action, such as dynamic ad insertion, based on the correlation of the metadata with the frame of the media stream.

摘要： The present invention relates to a method of hashing a perceptual vector model based on a multi-scale curvature. According to a first aspect, there is provided a method of hashing a perceptual vector model based on a multi-scale curvature including: generating a multi-dimensional feature coefficient matrix, and obtaining a multi-dimensional intermediate hash coefficient matrix; and obtaining a final binary hash matrix, and enabling the multi-dimensional binary hash matrix to be hierarchically authenticated. In addition, according to a second aspect, there is provided a method of hashing a perceptual vector model based on a multi-scale curvature including: generating a hash by using a hash function; and authenticating a vector model. In addition, an error detection probability for an object attack can be lower by about 2×10−5˜2.8×10−2, and a uniqueness probability is raised by about 0.014. In addition, an entropy can be raised by about 0.875˜2.149.
