1. A method for receiving and outputting one or more representations of a video signal in a video stream, the method comprising:

  • receiving a video stream, wherein the video stream includes one or more representations of a video signal, wherein each of the one or more representations of the video signal (OOMROTVS) includes a respective sequence of compressed pictures, wherein each of the OOMROTVS represents a respectively corresponding decimated version of the video signal, wherein each compressed picture of each of the OOMROTVS represents a respectively corresponding decimated picture of the video signal, wherein each respective picture of the video signal is represented by at most one compressed picture of each of the OOMROTVS;

    selectively shifting a first representation of the video signal relative to a second representation of the video signal;

    outputting plural reconstructed pictures, wherein each of the plural reconstructed pictures comprises information corresponding to one or more received compressed pictures that represent the same respective picture of the video signal, wherein each of the plural reconstructed pictures is reconstructed in accordance with plural pixel sampling lattices (PPSL), wherein each of the PPSL respectively corresponds to a decimated version of the video signal, and wherein each of the plural reconstructed pictures corresponds to a respective picture of the video signal;

    determining at least one impaired portion of a first received compressed picture that represents a first picture of the video signal; and

    outputting a first reconstructed picture corresponding to the first picture of the video signal, wherein the first reconstructed picture excludes information corresponding to the at least one determined impaired portion of the first received compressed picture (ALODIPOTFRCP), wherein the first reconstructed picture comprises information corresponding to a first plurality of received compressed pictures (FPORCP), and wherein each of the FPORCP represents the first picture of the video signal, wherein the FPORCP excludes the first received compressed picture.
