Abstract: A multimedia-source system comprises a reconstruction block for counting the units of an incoming digital packet intended to comply with a digital transport stream standard, the digital transport stream standard requiring fixed-length digital packets with each digital packet containing a standard number of units, to determine at least if the unit count matches the standard number of units; and a packet transfer block coupled to the reconstruction block for transferring the digital packet to a multimedia destination if the reconstruction block determines that the unit count matches the standard number of units.

Abstract: A method and apparatus for determining the position of a head with respect to a rotating magnetic disk within a disk data storage device using standard signals output from a head/drive assembly (HDA). Servo zone detect pulses are used to determine the position of the read/write head with respect to the servo cells. An index pulse determines the angular position of the head. A servo zone counter is incremented by one in response to a servo zone detect pulse. Accordingly, the servo zone counter maintains a unique value which is corresponds to each data wedge on a surface of the disk. A servo clock has a constant number of cycles between sectors. The servo clock is coupled to the clock input of a sector counter. A sector pulse is generated and the sector counter is reset to zero when the number of cycles counted indicates that the beginning of a sector is under the read/write head. A sector ID counter counts the number of sector pulses.

Abstract: This invention relates to a system for determining an effective address based upon a calculation performed on address information. Depending upon the result of the calculation firmware or hardware will control further operation of the system.
