Abstract: A page (BASE PAGE) modification method in a printer subsystem of the partial page buffer composing type for generation of distinct copy groups (CG #1, CG #2, CG #3) or versions of a base page. A printer subsystem receives a packet containing a page of characters, coded overlays/elisions (OL #1, OL #2, S #1, S #2) and combining data from an external source. The packet is translated into a linked list of character placement representations for each of the doubly indexed coded characters within the page. Elisions (S #1, S #2) from the page are made by inhibiting the formation of a linked list segment for each character sequence within elision markers set out in the page. In contrast, coded character overlays are appended to the list as addenda. The list governs the placement of characters into a partial page buffer, whose contents are system accessible in row major order.

Abstract: A system and method for detecting which head in a multiple head storage device contains errors and may be misaligned, and correcting for that misalignment so that the data can be recovered. These features allow for data to be recovered from the multiple head storage device in an efficient manner, without corrupting data read from those heads of the multiple head storage device which were not misaligned.

Abstract: A media streamer (10) includes at least one storage node (16, 17) for storing a digital representation of a video presentation. The video presentation requires a time T to present in its entirety, and is stored as a plurality of N data blocks, each data block storing data corresponding approximately to a T/N period of the video presentation. The media streamer further includes a plurality of communication nodes (14) each having at least one input port and at least one output port; a circuit switch (18) connected between the at least one storage node and input ports of the plurality of communication nodes, the circuit switch selectively coupling one or more of the input ports to the at least one storage node to enable the digital representation stored thereat to appear at one or more of the output ports; and at least one control node (18) coupled at least to the plurality of communication nodes and to the at least one storage node for enabling any one of the N blocks to appear at any output port of any of the plurality of communication nodes.

Abstract: Disclosed is an array controller for controlling the transfer of data from a host system to an array of data storage devices, comprising a processor connected via a local bus to a data buffer in which data is staged during said transfer. The array controller is provided with a buffer controller for controlling the operation of the buffer and is further provided with channel hardware for manifesting a plurality of data channels, selectable by the local bus address, over which data is transferred in and out of the data buffer.
