METHODS AND SYSTEMS FOR SEPARATE DELIVERY OF SEGMENTS OF CONTENT ITEMS

Systems and methods are described herein for transmitting a content item to a user device using multiple delivery protocols. The system receives, at a content source, a request for the content item from the user device. The system splits a digital stream of the content item into a first video signal and a second video signal. The system then transmits, via a unicast server, the first video signal for the content item to the user device, and transmits, via a multicast server, the second video signal for the content item to the user device. The system then causes for presentation on the user device the first video signal followed by the second video signal. In other embodiments, the system is optimized between the unicast delivery of a content item and a peer-to-peer delivery.

Method and apparatus for selection of content from a stream of data

A main stream contains successive content elements of video and/or audio information that encode video and/or audio information at a first data rate. A computation circuit (144) computes main fingerprints from the successive content elements. A reference stream is received having a second data rate lower than the first data rate. The reference stream defines a sequence of the reference fingerprints. A comparator unit (144) compares the main fingerprints with the reference fingerprints. The main stream is monitored for the presence of inserted content elements between original content elements, where the original content elements have main fingerprints that match successive reference fingerprints and the inserted content elements have main fingerprints that do not match reference fingerprints. Rendering of inserted content elements to be skipped. In an embodiment when more than one content element matches only one is rendered. In another embodiment matching is used to control zapping to or from the main stream. In another embodiment matching is used to control linking of separately received mark-up information such as subtitles to points in the main stream.

Delivery of different services through different client devices

A system that handles delivery of service(s) through a client device, includes an interactive service provider, a video service provider, and a client device. The interactive service provider inserts at least one of digital watermarks and digital fingerprints in non-programming media content. The video service provider transmits a media stream of the media content that includes programming media content and the non-programming media content. The client device detects at least one of the inserted digital watermarks and the digital fingerprints in the playback duration of the media content and renders overlay graphics on the media content. The client device activates at least one of input devices paired with the client device and the rendered overlay graphics. The client device further receives trigger responses over activated overlay graphics and displays an interactive view to enable delivery of service(s) in response to the trigger responses.

Systems and methods for encoding multiple video streams with digital watermarking for adaptive bitrate streaming in accordance with embodiments of the invention are disclosed. In one embodiment, a method for preprocessing multimedia content into streams with watermark information includes receiving a source content media stream, generating at least two variant preprocessed streams for each received source content media stream, where each variant preprocessed stream includes different watermark information in the same locations as the other variant preprocessed streams and where marked locations are spaced apart at least a distance equal to a predetermined maximum segment size, generating a set of embed location information describing marked locations in the variant preprocessed streams, generating at least one variant output stream from each variant preprocessed stream using video compression, partitioning each variant output stream into a set of segments, where each segment is no longer than the predetermined maximum segment size and contains at most one copy of the watermark information, generating a set of segment boundary information describing the boundaries of segments within the variant output streams and the boundaries are the same between variant output streams, and generating a segment selection list using the set of embed location information and the set of segment boundary information, where the segment selection list includes only one variant segment for each segment according to a watermark sequence and the digits of the watermark sequence correspond to the watermark information applied to each variant preprocessed stream.

IN-BAND METADATA FOR AUTHENTICITY AND ROLE-BASED ACCESS IN ENTERPRISE VIDEO STREAMING SERVICES

In various embodiments, a device receives a video stream. One or more frames of the video stream include embedded metadata that is embedded directly into the one or more frames. The device extracts the embedded metadata from the one or more frames. The device makes an authentication determination regarding the video stream, based on whether the embedded metadata includes a digital signature associated with a sender of the video stream. The device controls, based on the authentication determination, presentation of the video stream to a recipient user.
