Abstract: A method comprising: receiving a plurality of duplicates of a serial bit stream, wherein said serial bit stream comprises a sequence of data packets; continuously dividing each of said duplicates of said serial bit stream based on sequential time windows; with respect to each of said time windows, aligning said data packets associated with each of said duplicates of said serial bit stream, received within said time window, based, at least in part, on data packet similarity; and recreating in real time said serial bit stream by selecting at least one of said aligned data packets as representing a next data packet in said sequence of data packets.

Abstract: A method and system are provided for maximizing reception rate of datagrams transmitted in a packet-switched network, by minimizing their transmission rate. The method comprises: forwarding datagram groups from a first location towards a second location, wherein each of the datagram groups includes a plurality of datagrams each comprising a first indication for identifying the group to which it belongs, wherein each group is forwarded at a different time than others, and wherein all datagrams that belong to a certain group are forwarded at substantially the same rate; at the second location, determining an arrival rate of datagrams which belong to a first group; based on the determined arrival rate, determining whether a change should be affected at the forwarding rate of a second group of datagrams; and if so, forwarding the second group of datagrams at the new rate.

Abstract: A method and systems are provided for transmitting encoded video data over a packet switched network, by: (i) providing a plurality of encoded copies of video data, each encoded at a bitrate different from that of the others; (ii) transmitting one of the copies encoded at a first bitrate from a first end of a communication channel towards a second end of the communication channel; (iii) receiving the encoded copy at the second end and detecting the channel error rate associated therewith; (iv) at the first end, providing an indication associated with the detected error rate to enable transmitting from the first end another encoded copy having a different bitrate; and (v) transmitting a second copy encoded at a second bitrate, wherein the second bitrate is substantially equal to a maximal rate at which that encoded copy is recoverable at the second end with no noticeable apparent errors.
