1. A method of live broadcasting of light field media content from a capture device, comprising:
estimating an upstream bandwidth available to the capture device for uploading content in a network;
receiving, from the capture device, a request for a first service tier from a plurality of service tiers, wherein each service tier is based on a different network condition and is associated with a different respective quality level of network resources for transmission and processing of the light field media content captured by the capture device, the light field media content comprising an image array;
determining that a bandwidth associated with the first service tier is greater than the estimated upstream bandwidth;
determining a second service tier based on the estimated upstream bandwidth, wherein the second service tier is associated with a lower quality level of network resources than the first service tier;
determining parameters for reducing the image array to a reduced image array based on the second service tier, wherein determining the parameters comprises selecting a number of sub-aperture images from the image array based on maximizing feature saliency of the image array;
allocating, to the capture device, resources corresponding to the second service tier for transmission of the reduced image array; and
allocating, in a cloud system, resources corresponding to the second service tier for processing the transmitted reduced image array.
