Patent EP-0506435-A3 (EP)
IPC: H04N5/00
Filed: 1992-03-27
Abstract: A decoder for descrambling encoded satellite transmissions comprises 
an internal security module and a replaceable security module. The 
program signal is scrambled with a key (704) and then the key itself is 
twice-encrypted (710,715) and multiplexed (732) with the scrambled 
program signal. The decoder (706) performs a first key decryption using 
the second secret serial number (SSN₂) stored within the decoder (712). 
The partially decrypted key is then further decrypted by the replaceable 
security module (714) using the first secret serial number (SSN₁) stored 
within the replaceable security module (717). The decoder then 
descrambles (708) the program using the twice-decrypted key. The 
replaceable security module (714) can be replaced, allowing the security 
system to be upgraded or changed following a system breach. Either security 
module may become the active security module to finally decrypt the 
seed, selectable by a signal transmitted from the encoder (721).  
     Also disclosed is a method for transmitting (1284) the encrypted 
keys and secret serial numbers to a plurality of broadcasters (1286) who 
may in turn multiplex this signal with their own program signals so that 
any given channel received by a subscriber (1289) contains the key and 
secret serial numbers. Additionally, the decoder (1306,1390) may be 
upgradeable to accept both analog and digital video signals without 
significant redundant circuitry.

Filed: 1994-02-17
Abstract: A distributor unit (1) for heating and/or cooling systems operated by a heat carrier capable of flowing consists of a tubular housing (2) intended for vertical installation, in which a tube (5) of smaller cross-section is arranged coaxially and concentrically with the housing wall. The inner tube (5) forms an inner distributor chamber (6) and the annular space between the latter and the wall of the housing (2) forms an outer distributor chamber (7). In two planes (II-II and IV-IV) running at right angles to the longitudinal axis (Z-Z) of the housing (2) there are provided in each case radially running connections (10, 11, 12 and 13, 14, 15, respectively) to the outer (7) and inner (6) distributor chamber, respectively. Further connections (8, 9, 16) to the inner distributor chamber (6) are arranged at the end faces (3, 4) of the housing (2) and in an intermediate plane (III-III), respectively. The heating-circuit distributor (1) intended for vertical insertion by its longitudinal axis (Z-Z) can be pivoted for different installation not only about its longitudinal axis (Z-Z) but also about 180 degrees about its transverse axis and used in such a way that the inner and the outer distributor chamber can be used both as flow and as return chamber. <IMAGE>

Abstract: An ATM switch accommodates a plurality of input
lines. Conversion controlling units (16) are disposed
corresponding to the input lines. Each of the
conversion controlling units analyzes a header of a
cell received through the relevant input line and
accesses a common conversion table (20) corresponding to
routing information included in the header. The
common conversion table is disposed in common with the
input lines. The common conversion table collates
routing information of cells received through the
input lines with output routing information and stores
the collated data. Each of the conversion controlling
units extracts output routing information from the
common conversion table corresponding to the routing
information of a cell received through the relevant
input line, adds output routing information to the
header of the cell, and sends the resultant cell to

Abstract: A new predictive coding is used to increase the temporal frame
rate and coding efficiency without introducing excessive delay.
Currently the motion vector for the blocks in the bi-directionally
predicted frame is derived from the motion vector of the corresponding
block in the forward predicted frame using a linear motion model. 
This however is not effective when the motion in the image sequence is
not linear. According to this invention, the efficiency of this method
can be further improved if a non-linear motion model is used. In this
model a delta motion vector is added to or subtracted from the derived
forward and backward motion vector, respectively. The encoder performs
an additional search to determine if there is a need for the delta
motion vector. The presence of this delta motion vector in the
transmitted bitstream is signalled to the decoder which then takes the
appropriate action to make use of the delta motion vector to derive the
effective forward and backward motion vectors for the bi-directionally
predicted block.

Abstract: This invention describes how commercial silicon-on-insulator material can
be used to fabricate both wavelength filters and wavelength-selective
photodetectors. The silicon-on-insulator substrates (100) have a buried
silicon dioxide layer (102) and a thin top silicon layer (104) and are
manufactured for high speed electronics applications. However, in this
invention, the thin silicon layer (104) is used as the core of a
waveguide and the buried silicon dioxide (102) as a lower cladding
region. Another cladding layer (106) and a low index waveguide (108) is
fabricated on the commercial substrate to form an asymmetric waveguide
coupler structure. The added low index waveguide (108) and the original
thin silicon layer (104) form the two waveguides of the coupler. Since
the two waveguide materials have very different indices of refraction,
they are only phase-matched at one wavelength (111). Thus for a given
thickness of materials, only one wavelength (111) couples between the two
waveguides (104, 108). By adding an absorptive layer in the silicon
waveguide and electrical contacts, wavelength sensitive photodetection is
obtained. The buried insulator layer (102) is the key to device
operation, providing a very low index buried cladding region.
