Claim One:
1. An apparatus comprising: a communication interface; a memory; and a processor configured to: perform intra-prediction video encoding of a first frame of an input video signal to generate a first portion of an output video bitstream; select a subset of the first frame of the input video signal and provide the selected subset to the memory for storage therein, wherein the selection is based, at least in part, on the intra-prediction video encoding and control or coordination signaling; transmit the output bitstream or a signal corresponding to the output bitstream to another apparatus via the communication interface, wherein the subset of the first frame of the input video signal is also selected based, at least in part, on the control or coordination signaling from the another apparatus; and perform inter-prediction video encoding to generate at least one motion vector using the subset of the first frame that is stored in the memory and a second frame of the input signal, wherein 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.
