A data elementary buffer with underflow and overflow operational constraints is incorporated into a digital televison receiver to regulate the flow of data related to an ancillary data service to be presented in synchronization with a video or audio program element. The data elementary buffer ensures that data is received in time for decoding and presentation in synchronization with the video or audio element. The data elementary buffer also limits the amount of data that the receiver may be required to cache. The minimum size of the data elementary buffer is three times the size of a nominal data access unit or three times the quantity of data that the receiver can receive at the maximum rate in the period that a video element is displayed by the receiver.

An automatic segmentation system distinguishes foreground and background objects by first encoding and decoding a first image at a first time reference. Macroblocks are extracted from a second image at a second time reference. The macroblocks are mapped to pixel arrays in the decoded first image. Frame residuals are derived that represent the difference between the macroblocks and the corresponding pixel arrays in the previously decoded image. A global vector representing camera motion between the first and second images is applied to the macroblocks in the second image. The global vectors map the macroblocks to a second pixel array in the first decoded image. Global residuals between the macroblocks and the second mapped image arrays in the first image are derived. When the global residuals are compared with the frame residuals to determine which macroblocks are classified as background and foreground. The macroblocks classified as foreground are then blended into a mosaic.

Automated summarization of digital video sequences is accomplished using a vector rank filter. The consecutive frames of a digital video sequence can be represented as feature vectors which are successively accumulated in a set of vectors. The distortion of the set by the addition of each successive vector or the cumulative distance from each successive vector to all other vectors in the set is determined by a vector rank filter. When the distortion exceeds a threshold value the end of a video segment is detected. Each frame in a video segment can be ranked according to its relative similarity to the other frames of the set by applying the vector rank filter to the feature vectors representing the video frames. To produce a summary of a video sequence which is most representative of the content of the sequence, frames are chosen that correspond to vectors that are the least distant to or produce the least distortion of the set of vectors representing the segment. The ranking of the relative distortion can be used as the basis for selecting more than one frame from each segment to produce a hierarchy of summaries containing greater numbers of the frames having the most representative content.

A video system includes a plurality of frames of video each of which is defined by a plurality of scene elements. The scene elements for a respective frame together define an image of the frame. First auxiliary data is descriptive of a first scene element of the frame and second auxiliary data is descriptive of a second scene element of the frame. A sending device sends the frame of video, including its scene elements, the first auxiliary data, and the second auxiliary data, from the sending device to a receiving device.

A system target decoder operable to receive and process information. The system target decoder has a first demultiplexer that can demultiplex a transport stream into packets each having a given packet identifier. There are at least two transport buffers that can receive packets with the same packet identifier from the first demultiplexer. The transport buffers transfer the data to a smoothing buffer that in turn sends the data to a second demultiplexer. The second demultiplexer demultiplexes data from within the packets from the smoothing buffer into data access units.

A system for providing a data broadcast service for digital television receivers. The system includes a data authoring system for creating a program description, a data service encoder for combining the description with other information and encoding it, and a multiplexer for using the encoded data service information into a transport data stream. A receiver at the client end receives the transport data stream and extracts the data and the audiovisual program and builds a summary for the viewer.

A method and apparatus for synchronizing an event produced at a digital television receiver with an instant of a transmitted video, audio, or data element of a digital television program is disclosed. In a digital television system, a system time clock generates a timeline that is used to synchronize the presentation of the video, audio, and data elements of the television program. An application time is used in program production to synchronize instants of the several program elements. To synchronize a receiver generated event with an instant of a transmitted video, audio, or data program element, samples of the application time are transmitted to a receiver in a synchronized data service. A reconstructed application time is generated at the receiver as a function of the current system time, the application time sample, and the presentation time stamp of the data access unit in which the application time sample was transmitted. The presentation time of the program instant is associated with an application time correlating the event and the instant.
