摘要:
The process of identifying and associating information with objects in a hyperlinked video sequence is automated by creating an accessible list of object information, including semantic representations, which updates with the identification of new objects. Because objects appear in more than one shot in many video sequences, the invention makes guesses about the identification of objects in a newly segmented sequence. If it guesses the object correctly, the author is relieved of the need to manually search a database of object information to make the association.
摘要:
A system and method for adding hyperlinked information to a television broadcast in which an interactive content icon is used. The broadcast material is analyzed and one or more regions within a frame are identified. Additional information can be associated with a region, and can be transmitted in encoded form, using timing information to identify the frame with which the information is associated. A receiver displays the annotation information associated with the video signal in response to a viewer request on a frame by frame basis. The interactive content icon can be used to inform a viewer of the presence of hyperlinked information, for teaching the viewer how to use the system, and for informing the viewer about the hyperlinked information.

The encoder provides timestamp information to the data packet stream generator and the data packet stream generator synchronizes annotation data from the annotation source with a video signal from the video source in response to the timestamp information. The multiplexer generates a digital broadcast signal that includes an augmented transport stream from the transport stream and the encoded data packets.

摘要:
A synchronization mechanism embeds synchronization triggers into a television signal or stream at regular intervals. The triggers include an accurate representation of the time in which the triggers were embedded. A receiving device decodes the triggers and synchronizes its internal timer based on the triggers. In this regard, the receiving device obtains a reference time from the internal timer and computes an offset between the reference time and the trigger time. The computed offset is then applied to the reference time. With the receipt of each new trigger, the application compares the trigger time to a new reference time with the most recently computed offset value applied. If there is any variance between these two values, the application creates a new smoothed offset.

摘要:
Different tomographic images of the same subject matter are optimally related to one another through a two-step procedure whereby, first, movements are plotted on a subregion level, producing a vector map relating subregions in a first set of scan frames to subregions in another set of scan frames; and then, based on the aggregate of subregion movements, the invention characterizes the "global" displacement relating the volume represented by the first set of scan frames to that represented by the second set. More specifically, the invention generates translation and rotation vectors that describe the movements underlying shifts in subject matter from one scan to the other, and which can be applied to one frame set to align it with the other.

A tangible social network system comprises at least two interactive physical objects adapted for communicatively linking with each other, a visualization application for providing a visual representation of a user's tangible social network, and an object communication frame. An interactive physical object comprises a controller for forming a communicatively linked relationship with another interactive physical object and for receiving and responding to commands and data received from a linked object, and an audio or visual response subsystem. An object communication frame comprises a housing adapted to receive interactive physical objects, a communications subsystem for managing communications with installed objects and with interactive physical objects communicatively linked with installed objects, a controller, and a power subsystem for powering installed objects. The frame or objects may interact with a visualization application, comprising subsystems for receiving information about the user's tangible social network and deriving a representation of it, and a graphical user interface for providing the visual representation to the user.
