Title: Switching between bit-streams in video transmission
Inventor: KARCZEWICZ MARTA
IPC: H04N19/89
Filed: 2002-01-03
Abstract: The invention relates to a method for transmitting video information, in whi ch at least a first bit-stream (510) and a second bit-stream are formed. The first bit-stream (510) comprises at least one video frame, and the second bi t- stream (520) comprises at least one predictive video frame (524). At least partly different encoding parameters are used with encoding of the frames of  said first bit-stream (510) and said second bit-stream (520). At least one frame of said first bit-stream (510) is being transmitted, and the transmission is switched over from said first (510) to said second bit-strea m (520). In switching the transmission over from said first (510) to said seco nd bit-stream (520), a secondary switching frame (550) is transmitted, which ha ve been encoded using the encoding parameters of the second bit-stream (520) an d at least one reference frame from the first bit-stream (510). Said secondary  switching frame (550) is used as a reference frame in the reconstruction of said at least one predictive video frame (524) of the second set of video frames. The invention also relates to an encoder for encoding video information, a decoder for decoding a video information, and a signal representing encoded video information.

Abstract: The present invention relates to terrain navigation wherein an earth-reflected satellite signal is received from at least one reference signal source whose position is known (120), for example a navigation satellite. Based on information contained in the received signal a measured estimate of a shortest reflection distance (d1(t b)) to the satellite (120) is derived. A relative spatial movement (.DELTA.x, .DELTA.y, .DELTA.h) of a relevant craft (110) since a previous positioning instance (t a) is registered onboard the craft (110). Moreover, stored surface information is retrieved pertaining to an elevation (h1b) of the earth surface (130) in relation to the mean sea level (z0) at at least one geographical position (x1b, y1b). Based on the relative spatial movement (.DELTA.x, .DELTA.y, .DELTA.h) and the retrieved surface information at least one calculated estimate of the shortest reflection distance (d1(t b)) to the satellite (120) is derived. Finally, a geographical position (x1a, y1a, h1a) is determined on basis of the measured and calculated estimates of the shortest reflection distance (d1(t b)).      Thus, a highly reliable and entirely passive positioning may be accomplished on basis of external signals from as few satellites (120) as one.

Abstract: For converting a stream of flat articles (5), e.g., of stacks of different part products to be supplied to a binding machine, from transverse conveyance to parallel conveyance, two continuously operated conveyors (1 and 2) are provided, a transverse conveyor (1) having a direction (FQ) of transverse conveyance and serving as supplying conveyor (I) and a parallel conveyor (2) having a direction (FP) of parallel conveyance and serving as removing conveyor. The direction (FQ) of transverse conveyance and the direction (FP) of parallel conveyance encompass an angle. The articles (5) are pushed one after the other out of an outlet (13) of the supplying conveyor towards an entrance (21) of the removing conveyor. Before a trailing zone of the article (5) has left the supplying conveyor, a leading zone of the article is grasped by an alignment means (3) and is conveyed onwards with the speed of the parallel conveyor (2) in the direction (FP) of parallel conveyance and is such aligned to the entrance (21 ) of the removing conveyor, while the trailing zone is bent between the alignment means (3) and the outlet (13) of the supplying conveyor.  The stream conversion can also be operated in the reverse sense and again with continuously operated conveyors and nonetheless the articles are at all times during conversion safely guided.
