Patent number: 10511869Abstract: A system for resource provisioning for content delivery of multiple services is disclosed. The system may be configured to offer multiple services, wherein at least one first offered service is delivery of prerecorded content and at least one second offered service is content delivered according to a deadline. In at least one embodiment, the first offered service may be video content, and the second offered service may be broadcast television content. The system may also be configured to deliver at least a portion of the first offered service in advance of use of that portion of the first offered service such that resource demand in connection with delivery of service content of the second offered service at peak delivery may be reduced. As such, fewer resources are needed to provide uninterrupted service of the first and second offered services.Type: GrantFiled: November 16, 2016Date of Patent: December 17, 2019Assignee: AT&T Intellectual Property I, L.P.Inventors: Rittwik Jana, Vaneet Aggarwal, Xu Chen, Vijay Gopalakrishnan, Kadangode Ramakrishnan, Vinay Vaishampayan

Patent number: 9100127Abstract: A method and system for encoding and determining labels in a Dual Polarization (DP) Quaternary Phase Shift Keying (QPSK) signal is provided. A label frame, signature sequence, and data payload are combined using a complementary constant-weight code encoding (CCWC) encoder, the output of which is deinterleaved and differentially precoded to generate a polarized tributary of a DP-QPSK signal. This encoding can be duplicated for a second tributary of the DP-QPSK signal. The label can be determined using one or more polarizers and corresponding low-speed photodetectors, each applied to a copy of the DP-QPSK signal. The strongest output of the photodetectors is then used to determine the label. Alternatively, the DP-QPSK signal can be viewed as having XI, XQ, PH, and PV tributaries. These tributaries can then be translated into XI, XQ, YI, and YQ tributaries are encoded into a standard DP-QPSK signal.Type: GrantFiled: November 27, 2012Date of Patent: August 4, 2015Assignee: AT&T Intellectual Property I, L.P.Inventors: Mark D. Feuer, Vinay A. Vaishampayan

Patent number: 8131693Abstract: Methods and systems for managing the transfer of large data files across electronic data networks optimally in accordance with the desired results of the users. The present invention takes into consideration the user-defined transfer requirements, the data characteristics, and the characteristics of the entirety of the network, including both the access links and the backbone and processing and storage resources in the backbone. The present invention the enables users to more optimally transfer data within the limitations of the existing network capabilities, negating requirements to update local or remote network facilities.Type: GrantFiled: November 30, 2009Date of Patent: March 6, 2012Assignee: AT&T Intellectual Property II, L.P.Inventors: Matti A. Hiltunen, Richard D. Schlichting, Vinay A. Vaishampayan

Patent number: 6665646Abstract: A balanced multiple descriptive coder codes data in streams so that an acceptable replica of source data can be generated if either stream is lost. The balanced multiple descriptive coder may include a pair of coding branches, each branch including a coding chain and a prediction chain.Type: GrantFiled: December 10, 1999Date of Patent: December 16, 2003Assignee: AT&T Corp.Inventors: Sam John, Vinay A.

Patent number: 6516297Abstract: Data is transmitted using multiple description vector quantization by first quantizing the source vector at a lattice vector quantizer. After quantization, a labeling function is applied to the quantized source vector, creating a plurality of data streams. Each data stream is encoded and transmitted over a separate channel. Furthermore, the encoded data is decoded by first retrieving a representation of a sublattice point from a set of sublattice points from the data stream and then, determining a single data code word being associated with the retrieved representation of the sublattice point.Type: GrantFiled: December 23, 1999Date of Patent: February 4, 2003Assignee: AT&T Corp.Inventors: Sergio D.

Patent number: 6160505Abstract: A generalized frequency modulation (FM) based method for converting an analog signal to a digital signal. An analog input signal is sampled at the Nyquist rate. Each sample is converted to a corresponding modulated chirped FM signal. The digital signal is generated by sampling each modulated chirped FM signal at a rate which depends upon the bits per sample of the analog-to-digital (A/D) converter.Type: GrantFiled: September 24, 1998Date of Patent: December 12, 2000Assignee: AT&T CorpInventor: Vinay A.
