摘要： In a signal processing system, a programming system and method for a video network are provided. An event may trigger an RDMA controller to execute current instructions in a register update list. The triggering event may be a start-of-field signal from a live source or an end-of-frame signal. The current instructions may be used to modify the mode of operation of at least one of the network elements in the video network. The modification to the mode of operation may depend on whether the current video field is top field originated or bottom field originated. An interrupt may be used to initiate an interrupt handler that generates at least one new instruction and that updates the new instructions in the register update list. When a trigger occurs prior to an update of the register update list, the RDMA controller may execute the current instructions in the register update list.

摘要： A video processing system may implement a video scaling algorithm using interpolation based on polyphase filtering. A video or graphics scaler may be utilized to scale luma, chroma, and/or alpha information in a video image. The scaler may comprise a first polyphase sub-filtering with zero phase shift that generates an in-phase filtered output from an input video image and a second polyphase sub-filtering that generates an out-of-phase filtered output from the input video image. The video scaler may also comprise an interpolator that may generate a scaled video image based on the generated in-phase and out-of-phase filtered outputs and a scaling factor. The scaling factor may be determined based on an input video size (M) and a desired output video size (N). The interpolation of the generated in-phase and out-of-phase filtered outputs in the video scaler may be implemented by utilizing a Farrow structure.

摘要： Methods and systems for coordinating the handling of information are disclosed herein and may include scheduling multiple processing tasks for processing multimedia data by a processor. A portion of the scheduled multiple processing tasks may be preprocessed and the preprocessed portion may be buffered within a modifiable buffer that handles overflow and underflow. A portion of the buffered preprocessed portion of the scheduled multiple processing tasks may be executed. The scheduling may utilize a non-preemptive scheduling algorithm, such as an earliest deadline first (EDF) scheduling algorithm and/or a rate monotonic (RM) scheduling algorithm. The scheduled multiple processing tasks may include at least one maximum real deadline. The preprocessed portion of the scheduled multiple processing tasks may be outputted during processing of the blocking task, if a current task of the scheduled multiple processing tasks comprises a blocking task.

摘要： A system and method that computes correlation between a first signal and a second signal. The correlation is computed as a ratio of a numerator and a denominator. The numerator may be computed similar to computing the numerator of the Pearson correlation. The denominator may be computed by multiplying the variance of the second signal and the difference between the maximum and minimum value of the first signal. A threshold, which may be programmable, may be used to determine if the first and second signal match by comparing the numerator and the product of the threshold and the denominator. If the numerator is larger than the product then the first signal and the second signal match, otherwise, there is no match. The first signal may be a sliding window of a signal. The window may be slid over the signal until a match is found between the window and the second signal.

摘要： Certain embodiments of the invention may be found in a method and system for automatic aspect ratio detection and may comprise scanning lines in at least a selected portion of an image and locating a first reference pixel in one of the scanned lines. A corresponding sliding sum and a sliding number may be generated starting from the first reference pixel and a white edge determined based on the generated sliding sum and/or the generated sliding number. The first reference pixel may be a non-black pixel and a value which corresponds to and defines non-black may be variably defined. The sliding sum and the sliding number may utilize m bins, where m is greater than one (1). A luma sum threshold may be compared with the generated sliding sum to locate the white edge for aspect ratio detection.
