U.S. Patent Issued for DSL Video and Data Delivery Technology Employed by mPhase Technologies
Patent Issuance Covers The Technology That Ensures Accurate Synchronization Of MPEG-2 Broadcast Quality Video With DSL Data Streams
NORWALK, Conn.--(BUSINESS WIRE)--May 2, 2001-- mPhase Technologies (OTC BB: XDSL - news), the leading designer of broadcast digital television and high-speed data solutions for the telecommunications industry, announced that a second U.S. patent has been issued covering the system mPhase is deploying to provide a suite of DSL services via its Traverser Digital Video and Data Delivery System (DVDDS). U.S. Patent No. 6,208,666, issued on March 27, 2001 to the Georgia Tech Research Corporation (GTRC), is entitled ``System and Method for Maintaining Timing Synchronization in a Digital Video Network.'' The technology is exclusively licensed worldwide to mPhase Technologies, Inc. by GTRC, contracting entity for the Georgia Tech Research Institute (GTRI). Through its R&D contract with mPhase Technologies, GTRI collaborates on digital systems engineering and design.
According to the issuance, the patent covers ``a novel system and method for maintaining timing synchronization in a digital video network, in conjunction with a digital video and data delivery system, (that) makes possible the delivery of digital video content, bi-directional data services such as Internet data, and plain old telephone service (POTS) to an end user over a communications channel,'' typically the copper wire pair that extends between a telephone company central office (CO) and a customer's residential premises. However, the method of delivery covered may be any communication medium that supports the communication of compressed digital video, bi-directional data, such as Internet data, and POTS, and may also be a wireless connection. A distinguishing characteristic of the technology is that it enables the delivery of MPEG-2 broadcast quality video, therefore not suffering the limitations, reception difficulties or lower quality issues inherent in the Video Over Internet Protocol commonly used by the rest of the industry.
The core technology contained within the patent has the potential for numerous applications throughout the telecommunications industry. A device known as the ``framer'' keeps track of timing information contained with the data stream, and makes automatic adjustments, as needed, to ensure that timing accuracy is maintained whilst the data is being delivered to its ultimate destination. This technique sidesteps implementation problems facing others in the industry that must employ elaborate techniques to recover timing information lost during delivery due to network congestion. In the context of mPhase's more immediate application, the framer allows each Traverser DVDDS customer to enjoy MPEG-2 broadcast quality video and Internet data free from the quality limitations facing Video Over Internet Protocol techniques employed by others.
``This U.S. patent represents an extraordinary achievement and now fully protects our method of transmitting television over a telephone network,'' said mPhase president & CEO Ronald A. Durando. ``Not only is our Non-Internet Protocol (NIP)-based option a superior technology for telcos seeking to enhance their competitive positions and revenues by adding television programming, the Traverser DVDDS is highly scalable over a large number of users and is the most cost-effective model for providing live broadcast TV, high speed Internet access and standard telephone service.''
