Abstract: A source device being associated with an account uses playback of a media content item to cause a target device to become associated with the account. The target device enters an association mode and records a portion of the playing content. The target device provides the recording to a server that identifies the song (e.g., using a music fingerprint service) and uses the identification of the song to find the account that caused playback of the identified song. With the account identified, the server provides credentials of the account to target system. The target device accesses content or services using the account. As confirmation of receiving the credentials, the server causes playback of the content to transition to from the source device to the target device.

Abstract: Methods, apparatus and systems related to packaging a multimedia content for distribution are described. In one example aspect, a method for performing post-production editing includes receiving one or more footages of an event from at least one user. The method includes constructing, based on information about the event, a script to indicate a structure of multiple temporal units of the one or more footages, and extracting semantic meaning from the one or more footages based on a multimodal analysis comprising at least an audio analysis and a video analysis. The method also includes adding editing instructions to the script based on the structure of the multiple temporal units and the semantic meaning extracted from the one or more footages and performing editing operations based on the editing instructions to generate an edited multimedia content based on the one or more footages.

Abstract: A plurality of segment transitions in a video data stream is identified. The identifying the plurality of segment transitions includes recognizing an interface feature of a first application interface displayed in the video data stream and generating metadata associating a selected segment transition with a particular point in the video data stream. The interface feature indicates the selected segment transition among the plurality of segment transitions in the video data stream. A navigation system for navigating among the plurality of segment transitions in the video data stream is provided. Responsive to input, navigation to the selected segment transition is performed and the video data stream is displayed from the particular point.

Abstract: A method and device for optimal playback positioning in video content are provided. The present disclosure relates to a mechanism of tagging scenes or significant points in content in a prioritized way, and defines a mechanism to utilize this tagging associated with the content to facilitate stopping or starting at appropriate points for playback, e.g., when pressing a scene skip button to jump forward or back to another scene, or when pressing Play after inputting a fast-forward or rewind instruction. The method and device provide for displaying video content at a playback speed for viewing, receiving a first navigation instruction to navigate the video content at a speed faster than the playback speed for viewing, receiving a second navigation instruction to displaying of the video content, and determining a playback position of the video content based on at least one tagged frame of the video content.

Abstract: An approach is provided for enriching media with meta-information blocks. Specifically, one or more segments of one or more media files are processed to determine meta-information (e.g., topics, annotations, meta-data, etc.) related to the one or more segments. Based on the determined meta-information, other media or related meta-information is determined, analyzed, and appended to the original media as one or more meta-blocks. One or more relationships among the original and other media is then determined. Based on the determination of the one or more relationships, topic blocks (i.e., multi-topic links) are generated and associated with the original and other media. The addition of the meta-blocks and topic blocks to the original media enables either a renderer or a service to generate one or more composite media (e.g., a video mashup) based on the navigation and analysis of media determined as a result of traversing the one or more topic blocks.

Abstract: An apparatus which easily discriminates 3D (stereoscopic vision) contents from non-3D contents among recorded program contents can be provided. Further, a unit to prohibit unintentional generation of a virtual play list where 3D contents and non-3D contents are mixed can be provided. For these purposes, a 3D flag is recorded in a play list file. Further, upon virtual play list generation, the recorded 3D flag set values are obtained and it is checked whether or not 3D contents and non-3D contents are mixed.

Abstract: In various embodiments, a recording and playback manager of a digital video recorder (DVR), set top box, receiver or other device stores and accesses statistics in a statistics file related to average distances between reference frames (e.g., intra frames or I-frames) within blocks of the video data of the recording. Accessing these statistics during playback enables the system to more accurately locate reference frames to display while executing the playback in a trick mode such as fast forward, rewind or skip. The average distance between reference frames for a particular block of video data may be used to jump from one reference frame to the next reference frame in that block during playback in trick mode.

Abstract: Scene-based program accessing systems and methods are operable to present a program at a scene corresponding to a selected thumbnail-sized image. An exemplary embodiment selects a plurality of image frames from a program based upon a scene separation duration; generates a thumbnail-sized image from each of the selected image frames, and presents the plurality of thumbnail-sized images on a scene index. The scene index is configured to present the plurality of thumbnail-sized images in a time ordered sequence corresponding to a subject matter presentation sequence of the program, and each of the selected image frames are temporally separated from each other by the scene separation duration.
