SYSTEMS AND METHODS TO GENERATE COPIES OF DATA FOR TRANSMISSION OVER MULTIPLE COMMUNICATION CHANNELS
Publication number: 20230146420Abstract: Systems and methods to transmit data over multiple communication channels in parallel with forward error correction. Original packets are evenly distributed to the channels as the initial systematically channel-encoded packets. Subsequent channel-encoded packets are configured to be linearly independent of their base sets of channel-encoded packets, where a base set for a subsequent channel-encoded packet includes those scheduled to be transmitted before the subsequent packet in the same channel as the subsequent packet, and optionally one or more initial packets from other channels. The compositions of the sequences of the encoded packets can be predetermined without the content of the packets; and the channel-encoded packets can be generated from the original packets on-the-fly by the transmitters of the channels during transmission. When a sufficient number of packets have been received via the channels, a recipient may terminate their transmissions.Type: ApplicationFiled: November 17, 2022Publication date: May 11, 2023Applicant: Dolby Laboratories Licensing CorporationInventors: Mingchao Yu, Mark Craig Reed -
Patent number: 11533127Abstract: Determining data availability is disclosed, including: performing a data availability challenge with respect to a claimer node to determine whether the claimer node stores at least some elements included in a base layer in a digital tree corresponding to a data entity; and publishing a first set of elements associated with the base layer of the digital tree and the data availability challenge. Furthermore, encoding auditing is disclosed, including: obtaining a first set of elements associated with a base layer of a digital tree corresponding to a data entity; and generating an encoding validity determination of the digital tree based at least in part on whether the first set of elements is usable to recover a second set of elements associated with the base layer of the digital tree.Type: GrantFiled: January 29, 2020Date of Patent: December 20, 2022Assignee: Kaleidoscope Blockchain, Inc.Inventors: Mingchao Yu, Sreeram Kannan, Pramod Viswanath, Songze Li, Amir Salman Avestimehr

Patent number: 11012190Abstract: Systems and methods to transmit data over multiple communication channels in parallel with forward error correction. An optimized number is determined to partition a data segment of a given size into the optimized number of original packets of the same size, by reducing the cost of transmitting dummy data added to the original packets due to the partition, the data fields added to communication packets to support decoding, and redundant packets that are expected to be transmitted via a plurality of parallel channels before the termination of the transmission, as well as the computation cost that increases as a function of the number of original packets. Copies of packets are generated by distributing the original packets to the copies as initial packets and generating each subsequent channel-encoded packet by rejecting useless channel-encoded packets in view of packets assumed to have been received prior to the transmission of the subsequent channel-encoded packet.Type: GrantFiled: July 22, 2019Date of Patent: May 18, 2021Assignee: Dolby Laboratories Licensing CorporationInventors: Mingchao Yu, Mark Craig Reed
