<p>A digital media data stream including image data (32) and ancillary data (36) is received at a digital media input circuit. The ancillary data includes ancillary data words and an index characterizing the ancillary data words and/or image data. A control signal is generated at an interpreter (29) based upon the value of the index. The ancillary data words and/or image data in are processed based upon the control signal, words with different indexes being processed differently. A memory (60) storing control data values can be used in the interpreter, the index being used to address the memory.</p> |
