Method and apparatus for automatic slip defect management in a DVD drive

Abstract: A slip defect management apparatus and method efficiently avoids processing of bad data read from a DVD and provides very rapid slipping of defective sectors in a write operation.

Method and apparatus for seeking the burst cutting area of DVD media

Abstract: Methods and apparatus for reading data from the burst cutting area of a digital video disc. The present location of an optical head assembly is determined. The distance from the present location of the optical head assembly to the burst cutting area is calculated. The optical head assembly is moved by the calculated distance toward the burst cutting area. Data stored in the burst cutting area is read. The read data is checked for error. Repeat until there is no error in the data.

Algorithm and architecture for multirate polyphase video scaling with panoramic effect and enhanced video quality

Abstract: Traditional digital video scaling methods usually employ only linear approximation for output pixels, without any post processing. A new scaling method is presented in this paper. We propose an 8-fap 64 phases polyphase filter bank that combines a 3-tap peaking filter and a 6-tap 64 phases scaling polyphase filter. A third order cubic polynomial approximation method is introduced to generate linear and nonlinear scaling operations with the new polyphase filter structure. Panoramic effects are achieved by applying proper initial parameters for the first, second, and third order derivatives to control the behaviour of polynomial. Moreover, a simple implementation of horizontal and vertical peaking and scaling architecture is presented. Finally, examples showing different video enhanced results are provided.

Single integrated monitor with networking and television functionality

Abstract: A personal computer (PC) monitor system (30) is disclosed in accordance with an embodiment of the present invention to include a display unit (31) and a base coupled the display unit (31) for use by a user. The base (32) includes a control module responsive to input television (TV) signals (40) for processing the same to generate output TV signals (40), the control module further responsive to input PC data (42) for processing the same to generate output PC data (42), the control module further responsive to input network application data (36) for processing the same to generate output network application data (36), the control module further responsive to pointer data and low-resolution data, wherein the control module overlays the output network application data (36), the pointer data, and the low-resolution data to generate a first overlaid output data. The control module transfers the first overlaid output data, the output TV signals (40), and the output PC data (42) to the display unit (31) for viewing by a user.

Methods and systems of scanning an input device having multiple key switches

Abstract: A method of having multiple devices share a circuit's input/output (I/O) terminals includes applying first and second input signals to first and second I/O terminals to generate first and second output signals at the second and first I/O terminals, respectively. The first and second I/O terminals are coupled to first, second, and third devices via a plurality of signal paths. The method determines which, if any, of the first, second, and third devices is activated based on the first and second output signals. In some embodiments, the three devices correspond to three key switches of a keyboard through which a user can enter operation instructions. In some other embodiments, the three devices correspond to three signal receivers, which are controlled by a local or remote signal source that transmits activation signals in a wired or wireless manner.
