  • Patent number: 9247261
    Abstract: A video decoder includes an entropy decoding device that includes a first processor that generates first entropy decoded (EDC) data from a first portion of an encoded video signal and further that generates second EDC data from a second portion of the encoded video signal. A general video decoding device includes a second processor that generates a first portion of a decoded video signal from the first EDC data and that further generates a second portion of the decoded video signal from the second EDC data. The entropy decoding device and the general video decoding device operate contemporaneously in a pipelined process where the general video decoding device generates the first portion of the decoded video signal during at least a portion of time that the entropy decoding device generates the second EDC data from the first portion of the encoded video signal.
