Abstract: A data call control method for a mobile station includes detecting reception of a Release order message from a corresponding base station during a data call for a service option, determining if call retry restriction is necessary on the basis of the received Release order message, and restricting, if call retry restriction is necessary, retrying of the data call for the service option for a retry delay period. A device that implements such methods includes a radio frequency unit and a control unit to restrict retrial of a data call during the data call delay period.

Abstract: A video signal mixing apparatus and a method thereof, which is capable of minimizing timing jitter caused when onsynchronized video signals are digitally mixed. A signal subtractor subtracts a second video signal synchronized with a clock signal from a first video signal which is not synchronized with the clock signal, and a weighted value extractor divides one period of the clock signal into N intervals, detects the interval where a digital selection signal is generated, among the N divided intervals, and outputs a predetermined value (where 0≦predetermined value≦1) allocated to the detected interval as a weighted value. A multiplier multiplies the weighted value with the output of the signal subtractor and outputs the multiplication result, and a signal mixer mixes the multiplication result with the second video signal and outputs the mixed result as a mixed video signal. Therefore, error causing timing jitter is reduced to 1/N, thereby minimizing dot crawling of the mixed image.

Abstract: A non-linear response correction apparatus and method reduce look up table size and output error. In one embodiment, a range of an N-bit input signal is split into two or more sectors, based on a gradient of a non-linear correction curve and an allowable error, and then a N-bit input signal is divided into U upper bits and D lower bits where U and D depend on which sector contains the input signal. First and second look up tables read first and second data stored therein, respectively, using the upper bits of the digital signal as an address. The first data is the difference between a corrected signal and the input signal, and the second data is the gradient of the corrected signal with respect to the gradient of the input signal. The second data read from the second look up table is multiplied by the lower bits, and the first data read from the first look up table is added to the upper bits.
