1. A combiner processing system for support layer processing of video data, the combiner processing system comprising: a bit-rate reduction unit that receives an original video input (VOriginal), a video input signal for unconverted and reconstructed main layer (UBL), a motion vector input signal of a main layer from a main compressor (Umv), and a mode input from the main compressor (Umode) as inputs, wherein the bit-rate reduction unit detects textual information, edges, and busyness in one or more images in the video data on the input signals, and selectively reduces or processes large edges and overly-busy busyness areas in the video data to generate a bit-rate reduced signal output, wherein the bit-rate reduction unit is executed on a memory unit and at least one of a programmable device and another hardware device; a non-linear quantization module that selectively outputs non-linearly quantized and bit-rate reduced signals, wherein the non-linearly quantized and bit-rate reduced signals retain textual and other large-signal level information as well as small high-frequency details and small-signal level information present in an original version of the video data; an inter or intra selection and motion vector detection unit that makes a decision for inter or intra mode selection and detects motion vectors based on full image information reconstructed from an addition of upconverted image signals to residual signals; and a loop filter unit that provides a filtered reconstructed residual signal to the inter or intra selection and motion vector detection unit.
