Title: Splicing compressed packetized digital video streams
Inventor: CHEN DAVID
IPC: H04N21/226
Filed: 1997-10-10
Granted: 2007-01-09
Abstract: A secondary packetized data stream (IS), such as a commercial, is spliced with a primary packetized data stream (MS), such as a network television program. The system does not require decompression of the data in the primary data stream, and is particularly suitable for use at a cable system headend to allow the insertion of commercials from local businesses into a nationally broadcast television program. When a start signal (T_in)is received, a pre-splicing packet (700, 800, 900, 1000) of the primary stream is determined. The pre-splicing packet is the packet closest to the start time which carries an anchor frame (e.g., I or P frame) start code (706, 804, 905, 1003). To prevent a potential discontinuity at the decoder (168), the pre-splicing packet (700, 800, 900, 1000) is processed to discard the anchor frame data, and to insert a number of stuffing bytes (712, 812, 912, 1012) which is equal to the number of bytes discarded into an adaptation field of the pre-splicing packet. To further maintain continuity at the decoder, identifying data of the primary stream such as PID and PSI data, is retrieved and provided to the secondary stream. A number of null packets (430) are inserted into the output stream (OS) at the transition point between the main program and the commercial to prevent a buffer overflow at a decoder (168) which receives the output stream (OS).

Abstract: Cette installation lumineuse, commandée par un capteur de mouvement passif à infrarouge, comprend un socle (10), un ou plusieurs supports (11) de lampes fixés sur ce socle, ainsi qu'un boîtier (12), également fixé sur celui-ci et contenant le capteur de mouvement. Les supports de lampes comportent chacun une douille (13) destinée à recevoir une ampoule (16) du type projecteur ou analogue, ainsi qu'un abat-jour ou réflecteur (17) placé sur l'avant de la douille (13). L'ensemble support de lampe est relié au socle (10) par un bras (21) porteur, lequel est monté pivotant sur une paroi latérale de la douille (13), de manière décalée par rapport à l'extrémité de celle-ci, plutôt que d'être raccordé, de façon classique, au niveau de l'extrémité de la douille. Le montage (22) latéral pivotant du support permet à celui-ci de pivoter avec un bras de levier dont la longueur est nettement plus courte que celle hors tout du support de lampe. Ce bras de levier permet de monter le boîtier du capteur de mouvement plus près du socle tout en laissant un espace suffisant aux supports de lampe pour que ceux-ci puissent osciller sur une large plage de déplacement sans risquer d'induire de fausses activations, par interférence avec le boîtier (12) mobile du capteur de mouvement.

Abstract: A continuous flow chemical heat pump system is described which can be used for heating, refrigeration or for the two simultaneously.  The system includes a decomposition reactor and synthesis reactor.  Flow means are provided for moving a slurry containing particulate solids in a flow cycle through the decomposition reactor, then transferring to the synthesis reactor, through the synthesis reactor and then back to the decomposition reactor to repeat the cycle in a continuous manner.  Heating means are provided for heating the slurry passing through the decomposition reactor to decompose reacted solids of the slurry to release a reactive gas and leave a slurry containing unreacted solids.  The reactive gas is passed through a condenser in heat exchange flow with a cool fluid to cool the gas and at least partially condense it to a liquid phase.  Thereafter, the reactive gas is passed through a pressure reducing valve to reduce both the pressure and temperature.  It is then passed through an evaporator to evaporate the reactive gas to the gas phase by transferring heat to a warm refrigerant stream thereby producing a cooled refrigerant stream.  The evaporated reactive gas passes through the synthesis reactor in counter current flow contact with the slurry containing unreacted solids to thereby form a slurry containing reacted solids which is transferred back to the decomposition reactor.

Title: A method of coding and decoding audio signals
Inventor: BRANDENBURG KARLHEINZ
IPC: H04B1/66
Filed: 1996-11-21
Granted: 2002-08-06
Abstract: A method of encoding time-discrete audio signals comprises the steps of weighting the time-discrete audio signal by means of window functions overlapping each other so as to form blocks, the window functions producing blocks of a first length for signals varying weakly with time and blocks of a second length for signals varying strongly with time. A start window sequence is selected for the transition from windowing with blocks of the first length to windowing with blocks of the second length, whereas a stop window sequence is selected for the opposite transition. The start window sequence is selected from at least two different start window sequences having different lengths, whereas the stop window sequence is selected from at least two different stop window sequences having different lengths. A method of decoding blocks of encoded audio signals selects a suitable inverse transformation as well as a suitable synthesis window as a reaction to side information associated with each block.

Abstract: Cette invention concerne un circuit de traitement de vidéos animées numériques qui peut saisir, visualiser et manipuler des informations vidéos animées numériques du fait qu'on utilise la mémoire système d'un ordinateur comme mémoire tampon de données pour conserver les données vidéos condensées en provenance du circuit. Ce circuit peut accéder à la mémoire système par l'intermédiaire d'un bus normalisé. Un organe de commande intégré au circuit fait transiter le flux de données à destination ou en provenance, soit d'un point d'accès en entrée/sortie qui transfère un train de données de type pixels, soit du bus normalisé. Cet organe de commande fait transiter les données à destination ou en provenance du bus normalisé ou du point d'accès en entrée/sortie par l'intermédiaire de circuits conçus pour comprimer, décomprimer, mettre à l'échelle et stocker en mémoire tampon. Ledit bus normalisé peut être un bus PCI. Le circuit de traitement des vidéos animées possède un bus de données acceptant des données de type pixels et des données de synchronisation représentatives de la taille d'une image définie par des données de type pixels. Chaque composant qui traite les données de type pixels utilise et/ou génère des données de synchronisation, ce qui lui permet de traiter ces données de type pixels sans connaissance préalable du format de l'image. L'utilisation d'unités de traitement pour la gestion des deux formats de compression des données de vidéos animées, qui sont reliées au bus de données, permet d'exécuter une conversion entre des formats de compression tels que les formats MPEG et JPEG-animation.
