Abstract: A home security and control system for monitoring and controlling an external environment such as a home environment comprising: an Internet browser connectable to an extranet; an extranet located external to the home environment and accessible via the Internet browser; a communications server located in the extranet and adapted to interconnect on demand with one of a series of connection gateways located in predetermined home environments; and a connection gateway located in the home environment adapted to control and/or monitor the operation of at least one security device in the home environment; wherein upon accessing a predetermined address by the Internet browser on the extranet, the communications server connects to a predetermined one of the connection gateways to control and/or monitor the operation of the security device. The extranet can ideally be implemented as a Virtual Private Network (VPN) across an Internet substrate.

Abstract: Disclosed is a computer processor (300) comprising a plurality of processing units (FU_n) and communication means (302) by which the plurality of processing units are interconnected. The communication means is dynamically configurable based on a computer program to be processed such that the processing units can selectively be arranged in at least first and second distinct configurations. The first distinct configuration (eg. FIG. 5) has a larger number of the processing units arranged in parallel than the second distinct configuration (eg. FIG. 6), and the second distinct configuration has a deeper pipeline depth than the first distinct configuration.

Abstract: A method for performing an Inverse Discrete Wavelet Transform is disclosed. The method comprises inverse transforming, using filters (706–710) having specified filter widths, data from associated sub-bands in a first sub-band level, to form processed data in a corresponding sub-band in the second sub-band level. The method further inverse transforms, in a pipeline fashion, using second filters (712–716) having the same corresponding associated filter widths, the processed data in conjunction with corresponding data from associated sub-bands in the second sub-band level.

Abstract: A method (40) and apparatus (30) is described for performing image rendering of high resolution computer generated images using limited memory and constrained rendering architectures. An image is segmented into a plurality of tiles (110). A graphics renderer (17), which is usually used for rendering low resolution images onto a display device (19), is used to render one tile (110) at a time. The rendered tile images are combined to form a band of the image (101) and the image data of the band (101) is transferred to a printer engine (20) for printing. Each band (101) is rendered and transferred to the printer engine (20) until the whole image is printed.

Abstract: A method of selecting transform segments from a data stream (426), the stream comprising a plurality of blocks each comprising a plurality of transform segments, is disclosed. The selection reorders the transform segments in a block, and comprises, for each said block, steps of selecting a first set of transform segments (426-432) suitable for direct inverse transformation to form a first data segment, selecting a second transform segment (1612) which is directly inverse transformable given availability of the first set (426-432), identifying a third transform segment (1608, 1610) which is not directly inverse transformable given availability of the first set (426-432) and the second transform segment (1612), and selecting a fourth transform segment (1610, 1608) which is required to support direct inverse transformation of the third transform segment (1608, 1610).
