1. A system configured to perform scalable video encoding comprising:

  • a memory;

    a buffer; and

    a processing unit, wherein the processing unit is configured to;

    generate a base layer bit stream based on one or more frames;

    generate inter-layer data including either residual data or reconstruction data based on a block type of the base layer bit stream, wherein a same number of bits are used for the residual data and the reconstruction data in the inter-layer data;

    upsample the inter-layer data;

    generate an enhanced layer bit stream based on the one or more frames and the upsampled inter-layer data; and

    merge the base layer bit stream and enhanced layer bit stream into a video stream.
