  • Patent number: 7624337
    Abstract: A method and system are provided for tagging, indexing, searching, retrieving, manipulating, and editing video images on a wide area network such as the Internet. A first set of methods is provided for enabling users to add bookmarks to multimedia files, such as movies, and audio files, such as music. The multimedia bookmark facilitates the searching of portions or segments of multimedia files, particularly when used in conjunction with a search engine. Additional methods are provided that reformat a video image for use on a variety of devices that have a wide range of resolutions by selecting some material (in the case of smaller resolutions) or more material (in the case of larger resolutions) from the same multimedia file. Still more methods are provided for interrogating images that contain textual information (in graphical form) so that the text may be copied to a tag or bookmark that can itself be indexed and searched to facilitate later retrieval via a search engine.

  • Patent number: 7548565
    Abstract: Techniques for fast indexing of live video broadcasts are provided which incorporate both efficient manual processing and automatic indexing steps to generate semantically meaningful and practically usable highlight hierarchy of broadcast television programs in real-time. In one technique, a list of predefined keywords is provided, describing the highlights, and the manual marking process can be implemented by just a few mouse clicks. A technique is provided for grouping highlights into a semantic hierarchy in real-time. A technique is provided for efficiently generating highlight metadata on live broadcast programs, using a coarse-to-fine indexing methodology in order for a operator to quickly generate highlight summaries of live broadcast programs.

  • Publication number: 20050210145
    Abstract: A multimedia bookmark (VMark) bulletin board service (BBS) system comprises: a web host comprising storage for messages, a web server, and a VMark BBS server; a media host comprising storage for audiovisual (AV) files, and a streaming server; a client comprising storage for VMark, a web browser, a media player and a VMark client; and a VMark server located at the media host or at the client; a communication network connecting the web host, the media host and the client. A method of performing a multimedia bookmark bulletin board service (BBS) comprises: creating a message including a multimedia bookmark for an AV file; and posting the message into the multimedia bookmark BBS. A method of sending multimedia bookmark (VMark) between clients comprises: at a first client, making a VMark indicative of a bookmarked position in an AV program; sending the VMark from the first client to a second client; and playing the program at the second client from the bookmarked position.

  • Publication number: 20050203927
    Abstract: Fast metadata indexing and delivery for broadcast audio-visual (AV) programs by using template, segment-mark and bookmark on the visual spatio-temporal pattern of an AV program during indexing. The broadcasting time carried on a broadcast transport stream is used as a locator allowing direct access to a specific temporal position of a recorded AV program.

  • Publication number: 20050193408
    Abstract: Techniques (method, apparatus, system) are provided for efficiently delivering segmentation information of broadcast or other delivered programs to DVRs and the like associated with a conventional type program guide (for example, ATSC-PSIP or DVB-SI EPGs) for efficient random accessing to segments of a program which may be recorded in DVRs using the delivered segmentation information. The segmentation information may include segment titles, temporal start positions and durations of the segments of broadcast programs. Additionally, an interactive graphical user interface (GUI) is generated for browsing based on received segmentation information using thumbnail images from specific positions of a video file which can be generated either by hardware (H/W) or software (S/W) or firmware (F/W), or a combination thereof.

  • Publication number: 20050193425
    Abstract: A method for delivery and presentation of content-relevant information associated with frames in an AV program enables TV viewers to retrieve information on the contents (for example, objects, items, concepts and the like) associated with a frame or a set of frames (video segments) when they watch TV or video programs. The information relevant to frame(s) is delivered to a STB or DVR by third-party service providers through back channels such as the Internet if the information of how to accurately access the frames pointed by STB users are delivered to the service providers, and the content-relevant information may be presented in the form of a GUI for the TV viewer.

  • Publication number: 20040128317
    Abstract: Locally generating content characteristics for a plurality of video programs which have been recorded and displaying the content characteristics of the plurality of video programs, thereby enabling users to easily select the video of interest as well as a segment of interest within the selected video. The content characteristic can be generated according to user preference, and will typically comprise at least one key frame image or a plurality of images displayed in the form of an animated image or a video stream shown in a small size.
