Abstract: Encoded data decoding techniques. A data decoding agent determines a data segment size for a packet that includes a header and a data segment. The data decoding agent determines a segment end location based, at least in part, on the data segment size. The data decoding agent processes subblocks of data from the data segment. The data decoding agent compares a current location to the segment end location to determine if a current subblock of data from the data segments contains the segment end location. The data decoding agent triggers an exception handler if the current subblock contains the segment end location.

Abstract: The invention relates to a method and a device for simultaneously representing at least a first and a second sequence of pictures (M, S) in an overall picture. The inventive method is characterised in that picture data belonging to a picture of the first sequence of pictures (M) is stored in the form of a first picture data signal in a first picture memory (SPM). Picture data belonging to a picture of the second sequence of pictures (S) is stored in the form of a second picture data signal in a second picture memory (SPS). The picture data of the first and second picture data memory is read out according to a periodic screen signal (RS), whereby phase shift (SHIFTM, SHIFTS, tx) of the screen signal (RS) can be adjusted according to the first and/or second picture data signal.

Abstract: There is provided an image processing apparatus for describing a real image as a virtual object using space data formed based on a photo image of the real object, and generating a virtual image of the virtual object using the space data. The image processing apparatus captures the photo image of the real object from a real camera viewpoint position while illuminating the real object by an illumination light source placed at a real illumination position. The captured photo image is converted into space data in the form of an object for each pixel, and the space data is stored in a memory together with various illumination conditions at the real illumination position to allow a search at a later time.

The system has a control means which can determine, for each region, the type (e.g., graphics, text, computer programs, broadcast TV video, etc.) of the image material being displayed in the region. The system also has a video driver coupled to the display for providing image signals having contrast and brightness characteristics. The control means generates a control signal for causing said video driver means to adjust said contrast and brightness characteristics of said image signals according to the type of material being displayed in said region.

Abstract: A radio receiver for receiving a selected digital TV signal uses final intermediate frequency signals the carrier frequencies of which are multiples of symbol rate. The radio receiver has a match filter receptive of rectified samples of digitized intermediate-frequency signal and responsive to the amplitude of the intermediate-frequency carrier being modulated in accordance with the field synchronization code group to generate a pulsed response to the beginning of each data field. This pulsed response is used to determine when data segment synchronization information should occur, so its detection is more certain to be accurate and data segment synchronization is more rapidly determined. Symbol synchronization is rapidly inferred from the field synchronization and data segment synchronization, so that the samples in each data line can be counted.

Abstract: Motion picture distribution is performed by converting the motion pictures into digital video signals, combining the video signals with code elements or icons positioned in the active picture area of images formed by the video signals and sent via satellite to theaters or other receiving locations. The video signals are stored at the receiving locations and displayed repetitively to audiences by means of a projection television system. The coded areas in the pictures are used to transmit motion picture identification, theater authorization and other information which can be used to control the distribution and display of the motion pictures. Reports regarding playing of the motion picture are transmitted from each display site to the offices of the remote distributor. Motion pictures are edited by converting the film into video signals, inserting coded areas into the active picture areas of the video signals to provide time codes, edge codes and related information useful for editing.

Abstract: A receiver for VSB signals includes tuner channel changing circuitry. AGC circuitry, an IF FPLL and confidence counters, for indicating when signal acquisition or loss occurs. When a loss of signal indication is generated, the IF FPLL is reset, but not the tuner channel changing circuitry and the AGC circuitry, in order to quickly reacquire the signal. If the loss of signal indication persists for a predetermined time or for a predetermined number of loss of signal indications, the IF FPLL, the tuner channel changing circuitry and the AGC circuitry are all reset to reacquire the signal.

Abstract: A media production is formed from source media including at least one of audio media and visual media. The source media is received and analyzed to extract therefrom content information associated with a corresponding element of the source media. The content information is examined for at least one of the elements to determine a limited set of production rules applicable to the corresponding element. A user may selectively apply at least one of the rules to a corresponding one of the elements so as to alter the corresponding element, for example in duration, in synchronism with other elements. The altered element is then combined with at least one other of the media to form the media production.

Last, the method and apparatus reads the frame data out of the determined buffer.

Abstract: A system and method uses the closed captioning script to synchronize supplemental data with specified junctures in a video program. A parser parses the closed captioning script to identify a set of unique phrases, with each phrase having the same number of words. A program producer decides what points in the video program to introduce enhancing content. The producer associates supplemental data used to activate the enhancing content with specific key phrases of the closed captioning script that correspond to the desired points in the program. The parser creates a key phrase data file which contains a listing of the key phrases and their association to the supplemental data. The key phrase data file is delivered to viewer computing units at users' homes. When the program is played, the viewer computing unit monitors the closed captioning script to detect the key phrases listed in the key phrase data file.

Abstract: A television system comprises an electronic program guide (EPG) including a picture-in-picture (PIP) window and means for returning to a last channel viewed full screen (LCF) in a television viewing mode prior to entering the guide mode. The EPG displays a program list including a listing for the LCF and text identifying it as such. This last channel listing is positioned at the top of a program list area in the guide. The viewer returns directly to the LCF in the television viewing mode by setting a cursor to the last channel listing prior to exiting the guide mode. In guides including listings for future programs, the last channel listing remains in a designated position of the program list area.

Abstract: A three-dimensional model is created to represent an environment to be captured on video. A camera is fitted with pan, tilt and/or zoom sensors. An operator selects a location in the environment. The three-dimensional model is used to determine the three-dimensional coordinates of the location selected by the operator. Information from the pan, tilt and/or zoom sensors is used to transform the three-dimensional coordinates to a two-dimensional position in the video from the camera. Using the two-dimensional position of the video, a graphic is properly added to the video such that the graphic appears to be at the selected location in the environment.
