Abstract: A data broadcasting receiving terminal receives a data broadcasting signal from a broadcasting station to detect print-out data and a control signal associated with print-out from the data broadcasting signal. The data broadcasting receiving terminal, at a time point of the start of broadcasting, notifies an image forming apparatus of the detected print-out data and printing prohibition data included in the control signal associated with print-out. The data broadcasting receiving terminal acquires a preparation time required for print-out from the image forming apparatus and a time of restoration from a power saving mode and issues a command of printing start, in consideration of the time requirements, to the image forming apparatus so that print-out data is printed out at predetermined timing.

Abstract: The present invention relates to an improved interpolation based on motion compensation. In order to avoid interpolation artifacts in proximity to the image borders, in particular in letterbox type images, each motion compensated image data is subjected to a position validation in order to determine whether or not the motion compensated image data can be used for interpolation purposes. By comparing the position of the motion compensated image data in the referenced images with predefined borderlines, impermissible image data positions can be detected and interpolation based on such image data prevented.

Abstract: In a method and system for 3D comb synchronization and alignment of standard and non-standard video signals, a coarse synchronization is performed on a bottom frame, a current frame, and a top frame based on a bottom frame field count. The current frame is assigned the frame transferred immediately prior to a bottom frame whereas the top frame is assigned the frame transferred two frames. A current frame window signal and a top frame window signal may be used to lock the current frame and the top frame to a bottom frame vertical sync signal. After coarse synchronization, the video frames are finely aligned by correlating a phase difference between the subcarrier signals in each frame and modifying the phase difference until the correlation results in a specified phase locked value range. This method and system may facilitate the handling of video stream switching and non-standard data streams.

Abstract: An image signal processing apparatus having three processing portions. A first processing portion generates a motion class that corresponds to a target position in an output image signal based on an input image signal. A second portion generates a space class corresponding to the target position based on the input image signal and synthesizes the space class and the motion class to generate one class. A third portion selects multiple items of pixel data positioned in a periphery of this target position based on the input image signal and generates pixel data of the target position in the output image signal according to an estimate equation using the multiple items of pixel data and coefficient data corresponding to the class. These processing portions are respectively constituted of integrated circuits (ICs) having the same configuration. These ICs have first and second functional blocks. Each of the functional blocks changes its functionality according to setting.
