1. An apparatus, comprising: a video encoder for performing intra-prediction video encoding of a first frame of an input video signal thereby generating a first portion of an output video bitstream; and a memory for storing a subset of the first frame of the input video signal selected based, at least in part, on the intra-prediction video encoding and control or coordination signaling; and a transmitter for transmitting the output bitstream or a signal corresponding to the output bitstream to at least one destination device via a communication network; and wherein: the subset of the first frame of the input video signal also selected based, at least in part, on control or coordination signaling from the at least one destination device; the video encoder for performing inter-prediction video encoding thereby generating at least one motion vector based on the subset of the first frame of the input video signal and a second frame of the input signal a second portion of the output video bitstream; and the subset of the first frame of the input video signal being a down-sampled version of the first frame of the input video signal or a down-sampled version of one of a plurality of regions of the frame of the input video signal.
