Abstract: An apparatus and method for effectively implementing a unified clock-recovery system includes an analog frontend module that is configured to generate an analog-source timing reference signal that is based upon analog-source data. Similarly, a digital frontend module may extract a digital-source timing reference signal based upon digital-source data. A switch module may then select between the analog-source timing reference signal and the digital-source timing reference signal to thereby provide a selected input timing reference signal to a unified backend clock recovery module. The backend clock recovery module may then compare the selected input timing reference signal with an output timing reference signal in order to generate a timing error for advantageously adjusting a local clock to thereby compensate for the foregoing timing error.

Abstract: Transforming digital images including luminance data relating to points with first coordinates and chrominance data relating to points with second coordinates is performed. More particularly, the transforming is performed where one of the luminance data and the chrominance data is more numerous than the other. This is done by processing the least numerous data by filtering to obtain least numerous data relating to points with identical coordinates to those of the most numerous data.

Abstract: The present invention provides for inductive pick-up devices employing a diversity and adaptive antenna arrangement. By utilizing diversity and adaptive antennas, the pick-up can be installed by a consumer without use of a computer monitor or other device to determine alignment. In addition, the arrangement increases the level of signal available to a data decoding system. In combining the two types of pick-ups and using the best features of both, we additionally gain performance on synchronizing frame rate and picking up data.

Abstract: A film mode detection method using a periodic pattern of a video sequence comprises the steps of: computing every absolute value of differences between every pair of corresponding pixels in two fields which are arranged within a predetermined distance on a time line; comparing a sum of the absolute value of differences between every corresponding pixels in two fields with the first predetermined threshold value M1 and limiting the sum to the first threshold value if the sum is greater than the first threshold value; filtering the video sequence and calculating a power of the filtered sum; and comparing the calculated power with the second predetermined threshold value M2 so as to determine the signal as a film mode if the power of the sum is greater than the second threshold value.

Abstract: An auxiliary digital data extractor in a television receiver includes a source of a composite video signal. The composite video signal includes an auxiliary digital data component which is either a first frame code having a predetermined number of bits and auxiliary data in a first format, or a second frame code having the same number of bits and auxiliary data in a second format. A frame code detector is coupled to the composite video signal source. The frame code detector is responsive to one subset of the frame code bits to detect the first frame code and to a different subset of frame code bits to detect the second frame code. An auxiliary data utilization circuit is coupled to the composite video signal source and the frame code detector. The auxiliary data utilization circuit receives auxiliary data in the either first format when the first frame code is detected or the second format when the second frame code is detected.

Abstract: A method and system of noise filtering is provided. The pixels of a first filter mask are separated into groups based on luminance . . . The sizes of each group is determined and a largest group is selected. The distance of each group of pixels from the largest group is also calculated. Pixels in groups that are small compared to the largest group and far from the largest group are tagged as noisy. After tagging the noisy pixels, additional filtering can be applied to the pixels of first filter mask without degradation from the tagged pixels.

Abstract: A system and method for using a remote control device to simulate a skip search operation on a consumer appliance playing a recorded media. In response to a sensed activation of a skip search button, the remote control transmits at least one recorded media shuttle command to the consumer appliance and, after waiting a period of time, transmits an additional command to the consumer appliance to cause the recorded media to resume playback at a standard speed. When the media shuttle command is a fast forward command, the simulated skip search is effective for forwarding past timed portions of the recorded media. When the media shuttle command is a rewind command, the simulated skip search is effective for replaying timed portions of the recorded media.

Abstract: A method for placing overlay elements in images of a digital video so that desirable viewing areas of the images are not occluded by the overlay element, the method includes extracting frames from the video, each of the frames defining an image which may have one or more desirable viewing areas. For each frame, an area is selected in the image for placing an overlay element and the percentage the overlay element overlaps the desirable viewing areas is determined for the selected area. The overlay element is placed in the selected area if the percentage is below a maximum allowed predetermined percentage of overlapping. If it is not, one or more other areas in the image are selected and/or the size, shape, aspect ratio of the overlay element is changed until a position and/or size, shape, aspect ratio is found which minimizes occlusion of the desirable viewing areas in the image.
