US Patent:

6650636, Nov 18, 2003

Filed:

Oct 20, 1999

Appl. No.:

09/421961

Inventors:

Steven H. Bradshaw - Escondido CA
Bruce L. Carneal - Del Mar CA
Karl E. Moerder - Poway CA

Assignee:

Tachyon, Inc. - San Diego CA

International Classification:

H04L 1266

US Classification:

370352, 370474, 370522, 725 63

Abstract:

Transmission of TCP/IP data over a satellite link from a hub station to a plurality of remote units. The data, transmitted over the satellite link, uses the digital video broadcast (DVB) protocol. A field in the DVB header is used to indicate the location of the start of a new TCP/IP data packet within the DVB data. Use of a field in the DVB header to indicate the location of the start of a new TCP/IP data packet supports variable location of TCP/IP data within a DVB frame, and therefore more efficient use of the DVB bandwidth.

Assignee:

Tachyon, Inc. - San Diego CA

International Classification:

H04Q 7/38

US Classification:

370329, 370330, 370343, 370478, 370480, 455450, 455509

Abstract:

A system and method for allocating one or more portions of the frequency spectrum among a plurality of radio frequency (RF) transmitters and/or receivers. The system comprises a hub station that dynamically allocates the frequency spectrum in response to demand of the plurality of RF transmitters and/or receivers. Based on the demand, the hub station analyzes the state of performance of one or more groups of RF transmitters and/or receivers, and optimizes utilization of the assigned frequency spectrum.
