    Abstract: Video data is retrieved by a user device (41) from a database (49) as a plurality of video segments each having metadata (44) associated therewith indicative of the relative narrative interest of individual segments of the data, and is arranged such that it may be played at a selectable plurality of speeds. The speed at which each segment is to be played is selected in accordance with the metadata associated with that segment. This allows a “catch-up” facility to be provided to allow a viewer to watch the beginning of a sequence which is still being created (e.g a sports fixture in progress) at a variable speed so that the events of greater interest are displayed at normal speed (or in slow motion) and the less significant parts at a faster speed. The selection of the parts to be played at each speed can be tailored to the interests of the user, the relative interest of each segment, and the elapsed duration of the sequence to be viewed. The speed may be controlled by selective omission of frames, or groups of frames. Alternatively, separate streams may be generated for the different speeds available, and a manifest file generated specifying from which stream each segment is to be selected. Processing of the video stream to generate the various speed outputs may be in a client device (41) or in a client agent embodied in a content server device (420). The process may be controlled by the client device or by an agent in a request server (42).

    Abstract: Techniques and mechanisms described herein facilitate the delivery of prioritized side channel data to a client machine. According to various embodiments, base layer data may be transmitted to the client machine. The base layer data may include a plurality of base layer data segments. The base layer data segments may be capable of being used to present a media content item at a first quality level. Side channel data may be transmitted to the client machine. The side channel data may include a plurality of side channel data segments. Each side channel data segment may correspond with a base layer data segment. The side channel data segments may be capable of being combined with the corresponding base layer data segments to present the media content item at second quality level. The second quality level may be being greater than the first quality level.

    Abstract: Method for providing targeted content in image frames of a video and corresponding device A scalable and flexible solution for targeting a video through overlaying image frame zones with content that is targeted to individual users according to user preferences is provided. A video sequence is processed to determine sequences of image frames that comprise overlayable zones for overlay with targeted content. Features that describe these frames and these zones for a content overlay operation are stored in metadata that is associated to the unmodified video sequence. When the video is transmitted to a user, the metadata is used to overlay content in the overlayable zones, whereby the content is chosen according to the preferences of the user.

    Abstract: Various methods, systems, and apparatuses can be used to adjust the group of pictures size for an encoder during encoding operations. In some implementations, group of pictures size can be reduced during periods of higher likelihood of channel change, and increased during periods of lower likelihood of channel change. Such adjustment can facilitate faster display of pictures after a channel change due to anchor frames being more quickly received.
