- W57765977 abstract "ABSTRACT This paper presents a one-chip implementation of a two-dimensional sub-band analysis (and synthesis) function based on Perfect Reconstruction Modulated Filter banks (PRMF) which is able to split an input video signal into 8*8 sub-bands. This chip supports various data rates up to 36 MegaPixel/sec (half a HDTV data rate) and various bi-dimensional decompositions from the 2*2 one up to the widely used 8*8 one with all the intermediate solutions. Such versatility is due to the direct mapping onto silicon of the optimised architectures of both the analysis and the synthesis stages described in [2] and the use of embedded programmable delay lines. Attractive applications like local field/frame commutation modes, HDTV/TV compatibility, TV standard converters, interpolations/decimations are then possible with this chip. The chip is made up of 140 000 transistors for logic and pilelined computing tasks, plus a total amount of 65 KBit of RAM memories resulting in a 82 mm2 chip area in a 0.7 μm double-metal CMOS technology. Key words: Sub-band coding PRMF filter bank VLSI HDTV/TV Compatibility DCT" @default.
