1. A system for transmitting multimedia information via a network, comprising:

  • means for retrieving a frame of multimedia information for transmission over the network;

    means for converting the frame from a first color space to a second color space, wherein each component of the second color space is formed as a weighted combination of components of the first color space;

    means for slicing the frame into a plurality of frame slices;

    means for transforming each of the plurality of frame slices into a plurality of corresponding frequency domain components;

    means for quantizing the frequency domain components of each frame slice when it is determined that each frame slice is to be processed as one of an intra-slice and a refresh slice to generate quantized frequency domain components of each frame slice;

    means for variable-length encoding the quantized frequency domain components of each frame slice to generate compressed multimedia information associated with each frame slice;

    means for constructing network packets of the compressed multimedia information associated with each frame slice; and

    means for transmitting the network packets via the network.
