More Information
Summary:A block encode circuit (800) including a scanner (820) operable to scan a block having data values spaced apart in the block by run-lengths to produce a succession of pairs of values of Level and Run representing each data value and run-length, and wherein the Level values include one or more AC values succeeded by a DC value in the succession, and a Run-Level encoder (830) responsive to said scanner (820) to encode the values of Level and Run in a same AC to DC order as in the succession of pairs of values from said scanner (820) to deliver an encoded output. Other encoders, decoders, codecs and systems and processes for their operation and manufacture are disclosed.
