Benefits of technology

[0014] Synchronization generally comprises transmitting a bit or bits that are used by a receiver to synchronize it with a transmitter. The synchronization codes of the present invention may be used for synchronization between communicating devices. Since the codes are invalid for data, a receiving device will not confuse them for data, thereby increasing the robustness, or Quality of Service of the communication. In addition, the codes may be used for channelization of communications between devices in an environment where there are numerous devices communicating.

Problems solved by technology

Such transmissions require significant bandwidth to transmit the large data files in a reasonable amount of time.
These large data files, as well as the large data files that provide real-time home video are simply too large to be feasibly transmitted without an increase in system bandwidth.
The need for more bandwidth is evidenced by user complaints of slow Internet access and dropped data links that are symptomatic of network overload.

Abstract

A system, method and computer software product are provided. One embodiment of the present invention provides a method for generating and employing numerical sequences that may be used for synchronization codes. In one embodiment of the present invention, the derivation of numerical sequences, or codes is based on an encoding algorithm. These codes enable synchronization between communicating devices, and may also be used for channelization. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the subject matter of the disclosure contained herein. This Abstract is submitted with the explicit understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.

Description

[0001] This application claims priority under 35 U.S.C. §120 as a divisional of U.S. patent application Ser. No. 10 / 897,281, filed Jul. 21, 2004, entitled “Synchronization Code Methods.”FIELD OF THE INVENTION [0002] The present invention generally relates to communications. More particularly, the invention concerns systems and methods to derive and employ unique synchronization codes. BACKGROUND OF THE INVENTION [0003] The Information Age is upon us. Access to vast quantities of information through a variety of different communication systems is changing the way people work, entertain themselves, and communicate with each other. [0004] For example, because of the 1996 Telecommunications Reform Act, traditional cable television program providers have now evolved into full-service providers of advanced video, voice and data services for homes and businesses. A number of competing cable companies now offer cable systems that deliver all of the just-described services via a single broad...
