International Classification:

H04N 7/26

US Classification:

37524026, 375E07026

Abstract:

A method for processing a plurality of multilayer bit streams includes receiving a plurality of multilayer bit streams each having a base layer and at least one enhancement layer. One or more of the enhancement layers are extracted in whole or in part from at least one of the multilayer bit streams so that the plurality of multilayer bit streams are collectively reduced in their total bandwidth. Each of the multilayer bit streams are rewritten to a single layer bit stream. The single layer bit streams are multiplexed to form a multiplexed single layer bit stream.

International Classification:

H04N 7/26

US Classification:

37524002, 375E07026

Abstract:

A method for delivering streaming media content to client devices over a network includes receiving a plurality of media streams encoded at different bit rates. The media streams for each service contains common content to be received by one or more of the client devices. Each includes a plurality of segments having a prescribed duration. For each service a need parameter is obtained for each segment. Each need parameter reflects a bit rate needed to transmit over the network the respective segment of the media streams for that service at a given quality level. One of the media streams for each service is selected by allocating bandwidth to the media streams based at least on the need parameters for each corresponding segment of the media streams. The selected media streams are multiplexed to form a multiplexed stream. The multiplexed stream is adaptively streamed over the network to client devices.

Divicon, Inc. - Milpitas CA

International Classification:

H04J 324

US Classification:

370394

Abstract:

A remultiplexer is disclosed for communicating plural programs. Each program comprises one or more elementary streams that are encoded in relation to a single common time base corresponding to the respective program. The communicated programs originate from plural input transport streams that each comprises plural transport packets. Each transport packet contains a packet identifier indicating the data contained therein. Within each transport stream, unique packet identifiers are assigned to each elementary stream of each program. The data of each elementary stream is only contained in transport packets having a corresponding packet identifier. Each input transport stream contains time stamps for reconstructing the single program time base corresponding to each program conveyed therein. The remultiplexer has a data link module which receives the plural input transport streams. The data link module also selectively extracts transport packets from the received input transport streams.

Appl. No.:

6/529067

Inventors:

Mark R. Magee - Saratoga CA

Assignee:

GTE Communication Products Corporation - Stamford CT

International Classification:

H05F 300

US Classification:

361225

Abstract:

Apparatus for making an electret tape having an electrically conductive strip with a dielectric layer on one side thereof comprises tape supply and take-up reels arranged to move the tape from the former to the latter in an upwardly inclined plane and an electrostatic charging assembly between the reels having a dielectric fluid applicator for applying the fluid directly to the dielectric layer, a sponge-like electrode connected to a high dc voltage source, and an air blower for drying the fluid on the tape. The electrode is longitudinally spaced from the fluid application point in the direction of tape movement, engages the dielectric layer across its full width, and is wetted on the tape input side by the fluid on the layer. The blower is on the tape output side of the electrode with a baffle spaced closely to the dielectric layer between the blower and the electrode. This arrangement insures that the electrode is continuously wet and that the fluid is dried on the dielectric layer before the latter moves away from the electrode.

International Classification:

G08B 1316

US Classification:

367 94

Abstract:

Drift of the standing wave pattern in an acoustic doppler intrusion detection system in a confined space is compensated by adjusting the relative radiating and receiving positions of the radiator and receiver transducers, respectively, either mechanically or electrically until the signal level of the carrier wave at the receiver transducer is optimized. In the mechanical adjustment mode, either the receiver transducer or the radiating transducer is supported for movement relative to the other and is moved by a motor energized under the control of a signal level sensor circuit connected to the output of the receiver transducer. In another mode, a plurality of receiver (or alternatively radiator) transducers are connected through a switch to the signal level sensor circuit which in response to a drop in received signal level below a predetermined threshold, selectively switches the active transducer to optimize the received signal level. In still another mode, one of at least two radiator (or alternatively, receiver) transducers is connected through a variable phase shifter to the signal generator (or to the receiver circuit for the receiver transducer), the phase shifter being adjustable in response to the output of the signal level sensor to optimize the signal level at the receiver transducer. The invention comprehends the apparatus for and method of optimizing signal strength at the receiver transducer.

International Classification:

B05C 104

US Classification:

361225

Abstract:

Apparatus for continuously making an electret tape having an electrically conductive strip with dielectric layers on opposite sides thereof in which the tape is moved vertically in the direction of its length. A pair of opposed electrodes connected to a high voltage source and continuously wetted with a dielectric fluid contact the respective dielectric layers to electrostatically charge each layer. A second pair of identical electrodes connected to the high voltage source and the dielectric fluid supply is spaced above the other electrode pair and repeats electrostatic charging of the dielectric layers to insure uniformity of charge thereon. Fluid on the layers is dried by air blown against them as the tape emerges from the second electrode pair.
