摘要： A system-on-a-chip (SOC) includes a memory system, a data processor and a read only memory (ROM). The memory system includes random access memory and a memory controller. The data processor includes at least one functional block that communicates data with the memory system via the memory controller. The ROM stores data and one or more parity bits for detecting and correcting errors in the data. The data includes chip information and/or security information for the SOC. A method of using the SOC includes storing data in the ROM that includes chip information and/or security information for the SOC; storing in the ROM the one or more parity bits for the data; reading the data and the one or more parity bits from the ROM; detecting and correcting errors in the data using the one or more parity bits; and outputting the corrected data.

摘要： For spatial resolution conversion of an image signal, a magnitude of a motion vector is compared to a threshold value. Single channel interpolation is performed if the magnitude of the motion vector is greater than a threshold value, and multi-channel interpolation is performed otherwise. In addition, single channel interpolation is performed for spatial resolution conversion of any frame that does not refer to another frame.

摘要： A video decoder removes noise caused by a luminance signal component when separating a chrominance signal from a composite video baseband signal. The video decoder includes a first signal generator multiplying the composite video baseband signal by a cosine component having a predetermined frequency and low-pass-filtering the multiplied signal to generate a first signal, a second signal generator multiplying the composite video baseband signal by a sine component having the predetermined frequency and low-pass-filtering the multiplied signal to generate a second signal, a third signal generator differentiating the first and second signals and performing a predetermined operation on the differentiated signals to generate a third signal having a value corresponding to a frequency band in which the chrominance signal exists, an operating unit receiving the third signal and performing a predetermined operation on the third signal to output the chrominance signal, a fourth signal generator performing a predetermined operation on the first and second signals to generate a fourth signal having a value corresponding to the amplitude of the chrominance signal, and a noise removal unit receiving the chrominance signal, the third signal and the fourth signal and correcting the chrominance signal in response to the third and fourth signals to remove luminance component noise included in the chrominance signal.

摘要： An adaptive digital video signal processing apparatus and method for Y/C separation. In the video signal processing apparatus, an adaptive 2D BPF carries out Y/C separation through comb filtering and bandpass filtering selected according to local characteristics of an image (e.g., based on the direction in which an edge in the image extends in vertical and horizontal directions. The adaptive 2D BPF performs 2D bandpass filtering in general case. The 2D BPF adaptively executes a series of selections of the various filtering operations in a continuous manner.

摘要： A synchronization detecting apparatus includes a counter, an error detector, and a line length generator. The counter counts to a predetermined counter value in response to a clock signal. The error detector generates an error, which is the difference between a current counter value received from the counter and a previous line length, in response to a synchronization flag signal. The line length generator generates a current line length based on a compensated error and the predetermined counter value. The synchronization flag signal has an active level at a transitioning edge of a synchronization pulse signal contained in an input signal.

摘要： Sync positions are detected from a video signal. The detected sync positions are processed (e.g., averaged) to generate modified sync positions. The detected sync positions and the modified sync positions are selectively used to sample and synchronize a color signal derived from the video signal. For example, the detected sync positions and the modified sync positions may be selectively used to sample and synchronize the color signal responsive to differences between the modified sync positions. The invention may be embodied as apparatus and/or methods.
