摘要： A method for generating a video character in an on-screen display system. The method uses a HALT signal provided to the microprocessor which allows the microprocessor to finish executing its current instruction, but prohibits the microprocessor from beginning a next instruction. After a sufficient amount of time has passed to ensure that the microprocessor has completed its current instruction, an OSD interrupt signal is sent to the microprocessor instructing the microprocessor to begin OSD operations. Alternatively, the method uses a bus multiplexer which duplicates character data and sends the expanded data to a bus in order to enlarge characters displayed on the screen.

摘要： 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.

摘要： Certain embodiments of the invention disclose a method and system for processing in a non-line locked system. The phase relationship between the sub-carrier signal on consecutive video lines in a video comb filter is determined by synchronizing the two video lines. The synchronization is achieved by aligning the color bursts signals in each of the two video lines. The phase error between the two video lines is determined through the use of a correlation operation. The phase error between consecutive video lines is used to automatically adjust the delay lines used by the video comb filter. The line delay adjustment is provided by changing the values of a variable integer delay and a fractional integer delay. Line delay adjustments reduce the artifacts that occur in the separation of luma and chroma components of a composite video signal.
