Abstract: A signal adaptive filtering method for reducing blocking effect and ringing noise, a signal adaptive filter, and a computer readable medium. The signal adaptive filtering method capable of reducing blocking effect and ringing noise of image data when a frame is composed of blocks of a predetermined size includes the steps of: (a) generating blocking information for reducing the blocking effect and ringing information for reducing the ringing noise, from coefficients of predetermined pixels of the upper and left boundary regions of the data block when a frame obtained by deconstructing a bitstream image data for inverse quantization is an intraframe; and (b) adaptively filtering the image data passed through inverse quantization and inverse discrete cosine transform according to the generated blocking information and ringing information. Therefore, the blocking effect and ringing noise can be eliminated from the image restored from the block-based image, thereby enhancing the image restored from compression.

Abstract: A bandwidth allocation method used in a point-to-multipoint communication system, for efficiently using the bandwidth while shortening delay time. A central unit quantizes round-trip propagation delay times of subsidiary units, groups the subsidiary units, assigns the same quantized round-trip delay time to the same group, and allocates allocation request signal bandwidths to the subsidiary units of the same group when receiving allocation requests within a predetermined period. Based on the quantized round-trip delay time, the bandwidths are located as close as possible while the bandwidths do not temporally overlap with each other and as temporally ahead as possible. Data signal bandwidths are also allocated to the subsidiary units of the same group, based on the quantized round-trip delay time and requested amounts of data, in a manner such that the bandwidths are located as temporally ahead as possible but temporally behind in comparison with the allocation request signal bandwidths.

Title: Method and apparatus for interrupting interfolded sheets created by a lapping interfolder
Inventor: WHITE BARTON J
IPC: B65H33/12
Filed: 2003-06-10
Granted: 2012-09-25
Abstract: A system for forming a discontinuity or interruption in a stack of interfolded sheets, which are formed by a pair of folding rolls acting on a stream of overlapping sheets supplied to a nip area defined between the folding rolls. The stream of overlapping sheets is supplied to the folding rolls from a pair of feed rolls located upstream of the folding rolls. Normally, the feed rolls are operated at a surface speed substantially the same as the surface speed of the folding rolls, to feed the overlapping sheets to the folding rolls. When a desired sheet count has been attained, the feed rolls and the folding rolls are operated so as to eliminate the overlapping relationship between a downstream sheet and an upstream sheet in the stream of overlapping sheets. To accomplish this, the feed rolls and the folding rolls are operated at a differential rate of speed, which results in advancement of the downstream sheet relative to the upstream sheet in a manner sufficient to eliminate the overlapping relationship of the downstream sheet with the upstream sheet. Such elimination of the overlap between the downstream and upstream sheets separates one group of sheets in the stack from the next adjacent group of sheets, which facilitates separation of the groups of sheets for subsequent processing such as packaging. The folding rolls are operated at a substantially constant rate of speed, and the feed rolls are selectively slowed upon discharge of the downstream sheet therefrom, to slow advancement of the upstream sheet while the downstream sheet is moved downstream by the folding rolls. The slow operation of the feed rolls is maintained until the trailing edge of the downstream sheet is moved forwardly out of overlapping relationship with the upstream sheet, which occurs prior to the point at which the trailing edge of the downstream sheet and the leading edge of the upstream sheet reach the nip between the folding rolls. The folding rolls function to place the downstream panel of the upstream sheet onto the upstream panel of the downstream sheet in the stack of sheets, and separation between the downstream and upstream sheets functions to form a discontinuity or interruption in the stack of interfolded sheets, to divide the stack into groups of sheets according to a desired sheet count and to facilitate separation for processing.
