Patent ID: 8611418

Claim:
An apparatus comprising: a first circuit configured to generate an intermediate bitstream by transcoding an input bitstream carrying a picture, wherein (i) said input bitstream comprises a Joint Picture Expert Group (JPEG) bitstream, (ii) said picture is represented by a plurality of discrete cosine transform coefficients in said input bitstream, (iii) said discrete cosine transform coefficients form at least five bit-planes, (iv) said intermediate bitstream comprises a Motion Picture Expert Group (MPEG) bitstream, (v) said intermediate bitstream includes at least five encoded frames arranged in a sequence of one intra-frame followed by at least four consecutive predicted-frames and (vi) each of said encoded frames represents a different subset of said bit-planes; and a second circuit configured to (i) generate a plurality of decoded images by decoding said encoded frames of said intermediate bitstream in said sequence and (ii) recreate said picture by adding said decoded images to each other to rejoin said subsets of said bit-planes, wherein each of said decoded images when added increases a respective resolution of each one of a plurality of pixel values in said picture.
