Abstract: 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.

Abstract: The present invention relates to a method and system for generating and retargeting a three-dimensiona video signal for use on a target three-dimensional display device, wherein the three-dimensional video signal comprises three-dimensional video data suitable for driving a multi-view display device and reference disparity mapping data, the reference disparity mapping data indicative of a disparity mapping for the three-dimensional video data for a reference three-dimensional display device and wherein a target disparity mapping is derived based on the reference disparity mapping and characteristics of the reference three-dimensional display device and corresponding characteristics of the target three-dimensional display device, the resulting target disparity mapping is used for retargeting the three-dimensional video data using the target disparity mapping data into a target three-dimensional video data.

Abstract: A control unit of a multipath data transportation system that optimizes the load of the multiple communication paths of this system when the system transmits a data segment over these paths in parallel with forward error correction. The control unit determines an optimized number of packets to send over each path based on a prediction of quality for each path. The transmitted packets include systematic packets and coded packets.
