Channel bonding for ultra-high definition video background
View Patent ↗Systems and methods are provided for communication ultra-high definition (UHD) video. At the transmitter-side, a single packet stream may be generated based on a plurality of UHD video streams; and the single packet stream may be split into a plurality of sub-streams, with each sub-steam comprising at least one or more packets from the single packet stream. The plurality of sub-streams may be processes concurrently via a plurality of transmit paths, to generate a corresponding plurality of signals for transmission over a particular physical medium. At the receiver-side, the plurality of signals may be concurrently received and processed, via a plurality of receive paths, and the plurality of sub-streams may be reconstructed based on processing of the plurality signals. The plurality of sub-streams may be combined to re-generate the single packet stream; and the plurality of encoded UHD video streams may then be extracted from the single packet steam.
