COMPLEXITY DETERMINING APPARATUS FOR CONTROLLING ENCODING OF VIDEO SIGNAL

摘要

A complexity determining apparatus (16) is disclosed which comprises a source of a data signal and a subsampler system (60), coupled to the data signal source, for producing a subsampled signal representing the data signal. A variable bit rate (VBR) encoder (66) is responsive to the subsampled signal and produces an encoded signal representing the subsampled signal. A counter (68) accumulates the number of bits in the encoded signal and produces a complexity representative signal corresponding to the accumulated number of bits.
