4554561, 4554042, 455421, 4554221, 455424, 455436
Abstract:
Disclosed are methods, apparatuses and systems for tracking a location of a mobile device based, at least in part, on measurements over time. In response to measurements, particles in a motion model may be propagated in a first routing graph covering an area. Propagated particles may be indicative of a direction of movement along a second routing graph covering the same area or a larger area in some embodiments.

Dynamic Stream Interleaving And Sub-Stream Based Delivery

View page
US Patent:
20080256418, Oct 16, 2008
Filed:
Apr 15, 2008
Appl. No.:
12/103605
Inventors:
Michael G. Luby - Berkeley CA, US
Payam Pakzad - Berkeley CA, US
Mark Watson - San Francisco CA, US
Lorenzo Vicisano - Berkeley CA, US
Jourdan J. Clish - Fremont CA, US
Assignee:
Digital Fountain, Inc - Fremont CA
International Classification:
H03M 13/05
G06F 11/07
US Classification:
714762, 714E11023
Abstract:
A communications system can provide methods of dynamically interleaving streams, including methods for dynamically introducing greater amounts of interleaving as a stream is transmitted independently of any source block structure to spread out losses or errors in the channel over a much larger period of time within the original stream than if interleaving were not introduced, provide superior protection against packet loss or packet corruption when used with FEC coding, provide superior protection against network jitter, and allow content zapping time and the content transition time to be reduced to a minimum and minimal content transition times. Streams may be partitioned into sub-streams, delivering the sub-streams to receivers along different paths through a network and receiving concurrently different sub-streams at a receiver sent from potentially different servers. When used in conjunction with FEC encoding, the methods include delivering portions of an encoding of each source block from potentially different servers.

Block Partitioning For A Data Stream

US Patent:
20100211690, Aug 19, 2010
Filed:
Feb 12, 2010
Appl. No.:
12/705202
Inventors:
Payam Pakzad - Mountain View CA, US
Michael G. Luby - Berkeley CA, US
Assignee:
Digital Fountain, Inc. - San Diego CA
International Classification:
G06F 15/16
US Classification:
709231
Abstract:
A method for serving a data stream from a transmitter to a receiver includes: determining an underlying structure of the data stream; determining at least one objective, selected from a group of (1) reducing a start-up delay between when the receiver first starts receiving the data stream from the transmitter and when the receiver can start consumption of blocks of the data stream without interruption, according to the underlying structure, (2) reducing a transmission bandwidth needed to send the data stream, and (3) ensuring that the blocks of the data stream satisfy predetermined block constraints; and transmitting the blocks of the data stream consistent with the at least one objective and the underlying structure.

Enhanced Block-Request Streaming Using Url Templates And Construction Rules

View page
US Patent:
20110231519, Sep 22, 2011
Filed:
Sep 21, 2010
Appl. No.:
12/887492
Inventors:
Michael G. Luby - Berkeley CA, US
Mark Watson - San Francisco CA, US
Lorenzo Vicisano - Santa Clara CA, US
Payam Pakzad - Mountain View CA, US
Bin Wang - Fremont CA, US
Thomas Stockhammer - Bergen, DE
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
G06F 15/16
US Classification:
709219
Abstract:
A block-request streaming system provides for improvements in the user experience and bandwidth efficiency of such systems, typically using an ingestion system that generates data in a form to be served by a conventional file server (HTTP, FTP, or the like), wherein the ingestion system intakes content and prepares it as files or data elements to be served by the file server, which might include a cache. A client device can be adapted to take advantage of the ingestion process as well as improvements that make for a better presentation independent of the ingestion process. The client devices and ingestion system can be coordinated to have a predefined mapping and template for making block requests to HTTP file names that a conventional file server can accept through the use of URL construction rules. Segment size might be specified in an approximate manner for more efficient organization.

US Patent:
20110231569, Sep 22, 2011
Filed:
Sep 21, 2010
Appl. No.:
12/887483
Inventors:
Michael G. Luby - Berkeley CA, US
Mark Watson - San Francisco CA, US
Lorenzo Vicisano - Santa Clara CA, US
Payam Pakzad - Mountain View CA, US
Bin Wang - Fremont CA, US
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
G06F 15/16
US Classification:
709234
Abstract:
A block-request streaming system provides for improvements in the user experience and bandwidth efficiency of such systems, typically using an ingestion system that generates data in a form to be served by a conventional file server (HTTP, FTP, or the like), wherein the ingestion system intakes content and prepares it as files or data elements to be served by the file server. A client device can be adapted to take advantage of the ingestion process. The client device might be configured to optimize use of resources, given the information available to it from the ingestion system. This may include configurations to determine the sequence, timing and construction of block requests based on monitoring buffer size and rate of change of buffer size, use of variable sized requests, mapping of block requests to underlying transport connections, flexible pipelining of requests, and/or use of whole file requests based on statistical considerations.
