Title: High efficiency technique for coding a digital video signal
Inventor: KONDO TETSUJIRO
IPC: H03M7/36
Filed: 1986-10-30
Granted: 1991-11-05
Abstract: ABSTRACT OF THE DISCLOSURE         The invention relates to a high efficiency apparatus for coding   digital video  data  in which the number of bits per picture element  in the video data such as a digital video signal or the like is compressed!  The video data of a television picture plane is divided into a number of three-dimensional blocks, i.e., spatial blocks.  The picture element data in the block can be coded by the reduced number of bits by the bit compression by performing the coding process adapted to the narrowed dynamic range on the basis of the correlation among the picture elements in each block.      The transmission data of the number of bits reduced as compared with the number of bits of the original data can be formed.  By coding only the necessary frame by discriminating the movement of the image in the block, the redundancy in the direction of time can be removed.

Title: Pipe connection
Inventor: WEINHOLD KARL
IPC: F16L27/04
Filed: 1987-01-21
Granted: 1991-03-05
Abstract: ABSTRACT     A pipe connection for the connection of two pipe ends each provided with a collar.  One end is a socket part surrounding the pipe end assigned to it and sealed off with respect to it by a ring gasket.  This socket part surrounds a plug part joined to the other pipe end and is sealed off with respect to its outer wall by means of a further ring gasket.  The socket part is displaceable in an axial direction with respect to the pipe end assigned to it, the part of the pipe end engaging in the socket part being prevented from coming out by a shoulder. There is an outer collar on the socket part and on the plug part, with a quick closure that has detachably interconnected shell sections with radially inward-directed flanges and engages with the flanges behind both collars when the pipe connection is closed.  A ring part is inserted between the collar at one pipe end and the radially inward-directed shoulder on the socket part, which ring part has a wedge-shaped tapered face at one end.  The invention is characterized in that the face of the shoulder on the socket part turned toward the ring part and/or the surface of the collar lying against the ring part is tapered in a wedge shape at the surface turned toward the ring part.  Also a pipe piece is moulded or attached to the ring part, extending outward past the shoulder, coaxially between the shoulder and the pipe and at a distance from the latter, on which pipe piece handles are provided for turning the pipe piece with the ring part.

Abstract: ABSTRACT                  VIDEO IMAGE PROCESSING             A video processor identifies the head from a head against background scene using Vector Quantisation operating on a composite vector codebook including "head" vectors and "background" vectors.           The codebook is initially derived by storing several frames of an image training sequence (1); diffferencing adjacent frames (2); thresholding the difference data against a luminance threshold (3); median filtering (4); clustering the data sets (5); determining the minimum rectangle which will contain all the remaining non-zero pels (6); generating a border around the rectangles (7); generating a head codebook from the pels of the original frames of the image that fall within the borders (8); s       similarly generating a background codebook; and finally generating a composite codebook (9) in which "head" and "background" vectors are distinguished by flags. Then the head is tracked by Vector Quantising (10) the image with this codebook (9); and analysing the flags (11) (12) to obtain the head position (13).

Abstract: KEY SIGNAL ENCRYPTION AND DISTRIBUTION SYSTEM FOR CONTROLLING SCRAMBLING AND SELECTIVE, REMOTE DESCRAMBLING OF TELEVISION SIGNALS ABSTRACT OF THE DISCLOSURE A system and method for scrambling and selectively descrambling television signals that are transmitted to subscribers' descramblers in a subscription television system. A working key signal is generated by processing an "initialization vector" signal in accordance with the DES algorithm upon the algorithm being keyed by either a common category key signal or some other key signal. A unique encryption keystream is generated by processing the initialization vector signal in accordance with the DES algorithm upon the algorithm being keyed by the working key signal. A television signal is scrambled in accordance with the unique encryption keystream to provide a scrambled television signal. A plurality of unique encrypted category key signals individually addressed to different selected subscribers' descramblers are generated by processing the initial common category key signal in accordance with the DES algorithm upon the algorithm being keyed by a plurality of different "unit key" signals unique to different selected descramblers. The scrambled television signal, the initialization vector signal, and the plurality of encrypted category key signals are broadcast to the descramblers. A corresponding tier of DES algorithms are employed at the descrambler to reproduce the encryption keystream; and the TV signal is descrambled in accordance therewith. Each descrambler has its unique unit key signal stored in a secure memory for use in reproducing the common catagory key signal when the descrambler is addressed by its unique encrypted cateaory key signal.
