Abstract

A method of transmitting a video frame over a plurality of communication channels involves selecting a number of communication channels available between the transmitting and the receiving devices; partitioning spatially correlated pixels of the video frame into a number of different partitions equal to the number of selected communication channels; and transmitting the different partitions, where each partition is transmitted on a distinct communication channel among the selected communication channels. Such a method is suitable for use in a communication system, especially a wireless communication system, in which data of a channel can be lost or corrupted. The method can maximize diversity in the transport of the video frame pixels and improve robustness.

A method of transmitting a video frame from a transmitting device to a receiving device, the method comprising the following steps executed in the following order:

selecting a number of communication channels available between the transmitting and the receiving devices;
partitioning spatially correlated pixels of the video frame into a number of different partitions equal to the number of selected communication channels by defining linear blocks of pixels for partitioning the pixels of the video frame, wherein the number of pixels per block equals the selected number of available communication channels and wherein the linear blocks are staggered by shifting by at least one pixel from one row to another;
and
assigning each pixel of a block to a distinct partition;
and
transmitting the different partitions, where each partition is transmitted on a distinct communication channel among the selected communication channels.
