摘要： A television standards converter comprises a motion analyzer for analyzing the motion between consecutive fields of an input television signal of one television standard and for deriving motion vectors in dependence on the motion, a filter for recursively filtering the motion vectors, and an interpolator for aligning the fields in dependence on the filtered motion vectors so as effectively to represent static pictures, and means to effect conversion using the static pictures to derive the required output television signal of a different television standard.

摘要： Data formatting apparatus for formatting variable bit length data words into successive fixed bit length data words comprises an N-bit circular buffer comprising a plurality of concatenated buffer sections, each buffer section having the same bit length as one of the fixed bit length data words. A modulo-N counter generates a count of the cumulative length of received variable bit length data words. Each received variable bit length data word is stored in the N-bit circular buffer at a bit position dependent on the count signal, and, in response to a detection that data has been stored in all of the bits of that buffer section, the stored data from that buffer section is output as a fixed bit length data word.

摘要： A serial data decoder is described employing a bank of parallel primary Huffman decoders 70 each operating to decode a stream of variable length code words with embedded control code words into a stream of fixed length index values. The fixed length index values are fed to a secondary decoder which operates under control of the fixed length index values representing control code words to decode the fixed length index values representing the variable length code words into output data.
